Best AI Search Tools in 2026: 8 AEO Tools Compared

The best AI search tools in 2026 are Profound, Peec AI, Otterly, AIclicks, SE Visible, Semrush's AI Visibility Toolkit, Ahrefs Brand Radar, and HubSpot AEO. All eight do the same core job: they send buyer questions to AI engines such as ChatGPT, Gemini, Perplexity, and Google's AI answers on a schedule, then record which brands each answer names and which pages it cites.

Vendors sell this category under three names: AI search tools, AI visibility tools, and AEO tools. If you came for an AI search engine to search with, such as Perplexity or ChatGPT search, this is a different list. These tools measure how those engines talk about your brand.

The eight differ less on features than on three things: which engines a plan includes, what one unit of tracking costs, and whether the tool also helps with the work. Every engine list and price below comes from the vendor's own site, read on 2 October 2026.

One disclosure first. RankZero is a done-for-you AI SEO agency with its own tracking engine, so we left ourselves out of the eight. Where we fit, and who should pick one of these tools instead, has its own section near the end.

Key Takeaways

• Listed entry prices on 2 October 2026 run from $29 a month (Otterly Lite, 15 prompts) and $50 a month (HubSpot AEO, 25 prompts) up to custom Enterprise contracts at Profound.
• The engine list is where plans differ most. Otterly includes four engines and sells Gemini, Google AI Mode, and Claude as add-ons. Peec AI and AIclicks let you choose three models on the entry plan. SE Visible tracks the same engines on every plan.
• Compare prices by answers, not by prompts. One prompt on three engines every day is about 90 answers a month, and both Peec AI and Ahrefs print that arithmetic on their own pricing pages.
• AI search tools and AEO tools are the same products. The label changes with the vendor and the feature set stays the same.
• A tool reports the gap. Closing it is content, technical, and citation work, so the real decision is who does that work after the dashboard is live.

What AI Search Tools Measure

An AI search tool sends a fixed set of prompts to each AI engine and stores every answer. From those answers it works out how often your brand is named, how often your pages are cited as a source, and how you compare with the competitors named beside you.

The four metrics, and a setup you can run before you buy anything, are in our AI search tracking guide. This page is about choosing the software.

The eight tools fall into three types:

• Dedicated trackers: Profound, Peec AI, Otterly, AIclicks, and SE Visible. AI answers are the whole product.
• SEO suite modules: Semrush's AI Visibility Toolkit and Ahrefs Brand Radar. AI answers sit beside the keyword and backlink data you already use.
• A CRM add-on: HubSpot AEO. AI visibility sits beside your marketing and CRM data.

The type decides most of the fit. A dedicated tracker usually goes deeper on prompts and engines, and a module saves you a login.

If your shortlist is about keyword rankings at scale, that is a different purchase, and our comparison of enterprise rank trackers covers it.

AI Search Tools, AEO Tools, AI Visibility Tools: One Category

The three names describe the same software. Which one you see depends on who is selling.

HubSpot calls its product AEO. Profound names its tracker Answer Engine Insights and has a solution page for AEO teams. Ahrefs says Brand Radar helps you "turn SEO into AEO."

Semrush sells an AI Visibility Toolkit, and SE Visible describes itself as an AI visibility tool. Otterly calls its product AI search monitoring and includes a Generative Engine Optimization audit. Peec AI's own page title says AI search analytics.

So an "AEO tools" shortlist and an "AI search tools" shortlist should contain the same vendors. Answer engine optimization is the work, and an AEO tool is the software that measures whether the work is landing.

One split is real: tools that measure, and tools that also help you act.

Several of the eight now go past reporting:

• Otterly includes URL-level GEO audits, 1,000 a month on its Lite plan.
• AIclicks includes AI-optimized articles in every plan, from 5 a month on Starter, and sells managed services beside the software.
• Profound pairs its tracker with AI Marketer and Agents, which run on credits.
• Semrush adds AI search checks to Site Audit, for up to 100 pages on the standalone toolkit.
• HubSpot AEO returns prioritized recommendations with its visibility score.

Recommendations still need someone to carry them out. Keep that in mind when a demo moves from the chart to the to-do list.

How AI Search Tools Are Priced: Prompts, Engines, Frequency

Every vendor prices the same unit, even when the plan pages look different. The unit is one answer: one prompt, sent to one engine, one time.

Peec AI says it directly. Its pricing page defines monthly AI answers as "calculated by multiplying tracked prompts by active models and tracking frequency."

Ahrefs does the same sum in checks: "5 prompts on 1 platform = 150 checks/mo" at one check a day. So 25 prompts on three engines, run once a day, is about 2,250 answers a month.

Three pricing shapes follow from that unit:

1. Flat: One price and a fixed engine list. HubSpot AEO is $50 a month for 25 prompts on three engines. SE Visible tracks the same engines on every plan, and plans differ only on prompts and projects.
2. Choose your engines: Peec AI lets you choose three models on its Starter, Pro, and Advanced plans. AIclicks lets you choose three, four, or six models depending on the plan.
3. Base plus add-ons: Otterly includes four engines, then charges per extra engine by plan: Gemini or Google AI Mode adds $9 a month on Lite and $59 on Standard. Semrush sells 50 more prompts for $60 a month. Ahrefs bills overage at $0.020 per check.

If you want flat pricing, the first shape is the one to shortlist. If you want the most engines for the least money, the second and third need the sum done before the demo.

Put three questions to every vendor: which engines are in the base price, how often does each prompt run, and how many answers a month does that make?

The 8 Best AI Search Tools Compared

These are in no ranked order. Dedicated trackers come first, then the suite modules, then the CRM add-on.

Prices are monthly-billing list prices in US dollars, as shown on each vendor's site on 2 October 2026. Most vendors discount annual billing.

Profound

Best for: enterprise marketing teams that need SSO, SOC 2, and a tracker that comes with agents

Engines: up to 9 answer engines on Enterprise. The free plan covers ChatGPT, Gemini, and Google AI Overviews.

Price as listed: a free plan that runs for 7 days, then custom Enterprise pricing

Profound's pricing page lists two plans and nothing in between. The free plan runs 50 prompts daily for 7 days on three engines, in one language and one region.

Enterprise is a tailored package. It lists a custom prompt tracking plan, up to 9 answer engines, dedicated support, and SSO/SAML with SOC 2 compliance.

Beyond tracking, Prompt Volumes shows what people are prompting answer engines with. Agent Analytics tracks AI-sourced traffic through integrations such as Cloudflare, Vercel, and Google Analytics. AI Marketer runs research and writing tasks on credits.

Pick something else if you need a published monthly price to put in a budget line. Profound does not print one.

Peec AI

Best for: SEO and content teams that want everyone in the tool without paying per seat

Engines: choose 3 models on Starter, Pro, and Advanced. Enterprise lists up to 13 LLM models.

Price as listed: see Peec AI's pricing page. We have not quoted a figure here.

Peec AI's plans are built on prompts and projects. Starter lists 50 prompts and 1 project, Pro lists 150 prompts and 2 projects, and Advanced lists 350 prompts and 5 projects.

Every plan lists unlimited users and daily tracking. Advanced adds multi-country tracking and a Looker Studio integration.

The models you can choose from include ChatGPT, Google AI Mode, Google AI Overviews, Microsoft Copilot, and Gemini. Extra models are sold as add-ons, priced on the prompts in your plan.

Enterprise adds API access, single sign-on, and a choice of daily or weekly tracking. Agencies get a separate pricing page for tracking prompts across multiple brands.

Pick something else if you need more than three engines on a small plan. The add-ons change the sum quickly.

Otterly

Best for: solo marketers and small teams that want the lowest listed entry price, and agencies that qualify for its partner program

Engines: ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot are included. Gemini, Google AI Mode, and Claude are paid add-ons.

Price as listed: Lite $29 a month (15 prompts), Standard $189 a month (100 prompts), Premium $489 a month (400 prompts), Enterprise custom from 1,000 prompts

Otterly's pricing page lists daily tracking and unlimited team members on every plan. Lite comes with one workspace. Standard and Premium come with unlimited workspaces.

Standard is where the integrations start: API access, MCP access, and a Google Looker Studio connector. An extra 100 prompts costs $99 a month on Standard and Premium.

For agencies, Otterly runs an Agency Partner program on top of Standard or Premium. It lists pitch workspaces for prospects, reports in Looker Studio with your branding, and more prompts: 150 on Standard and 500 on Premium.

Pick something else if Gemini or Claude matter to your buyers and your budget is fixed. On Standard, Gemini adds $59 a month and Claude adds $109.

AIclicks

Best for: content teams that want tracking and drafted articles in one subscription

Engines: choose 3 models on Starter, 4 on Pro, and 6 on Business, from a menu of 11 that includes ChatGPT, Gemini, Perplexity, Google AI Overviews, Google AI Mode, Claude, and Microsoft Copilot

Price as listed: Starter $59 a month (30 prompts), Pro $189 a month (150 prompts), Business $499 a month (300 prompts), Enterprise custom

AIclicks' pricing page lists daily prompt runs on every plan. It also states the answer count outright: 4,650 LLM responses a month on Starter, 18,600 on Pro, and 55,800 on Business.

Each plan includes AI-optimized articles: 5 a month on Starter, 15 on Pro, and 30 on Business. GA4, API, and MCP integrations start on Pro.

Pro and Business list unlimited websites and unlimited countries per project. Starter is limited to one country.

Pick something else if you only want measurement. Part of what you pay for here is content output.

SE Visible

Best for: agencies and teams that want a large prompt allowance with every engine included

Engines: ChatGPT, Gemini, Perplexity, Google AI Mode, and Google AI Overviews, on every plan

Price as listed: Basic from $99 a month (200 prompts, 3 projects), Core from $189 a month (450 prompts, 5 projects), Plus from $355 a month (1,000 prompts, 10 projects)

SE Visible is built by the SE Ranking team and sold as its own product. Its plans are the simplest to compare: the engine list never changes, so you are only choosing prompts and projects.

It lists unlimited users, multiple brands or clients in one account, and CSV export. That combination suits an agency that wants one login for the whole team.

Country coverage is narrower than some rivals. The site lists the US, UK, Canada, France, Germany, the Netherlands, and Spain, in five languages.

Pick something else if your buyers are outside those seven countries, or if you need Claude or Microsoft Copilot tracked today.

Semrush AI Visibility Toolkit

Best for: teams already working in Semrush every day

Engines: Semrush's help page names "platforms like Google AI Mode and ChatGPT." We did not find a full engine list on the pages we read.

Price as listed: the standalone toolkit is $99 a month. Semrush One bundles SEO and AI visibility from $199 a month.

Semrush's toolkit page lists what $99 a month includes: 1 domain, 25 prompts for Prompt Tracking, and 300 daily queries in its AI analysis reports. Extra domains cost $99 each, and each extra user needs another $99 license.

Semrush One raises the prompt limits. Starter is $199 a month with 50 prompts tracked daily, Pro+ is $299 with 100, and Advanced is $549 with 200.

Prompt Research is the report to look at in a demo. It shows topic-level volume, difficulty, and intent, which works like keyword research for prompts.

Pick something else if AI visibility is your main metric. At 25 prompts the standalone toolkit is a small allowance, and white-label reporting is a separate add-on.

Ahrefs Brand Radar

Best for: established brands that want a benchmark without any setup, and existing Ahrefs users

Engines: Google AI Overviews, Google AI Mode, ChatGPT, Perplexity, Gemini, and Copilot. Claude is available for custom prompts and uses 8 checks per update.

Price as listed: custom prompt packages from $50 a month for 2,500 checks. The AI Visibility Index is $199 a month.

Brand Radar tracks visibility two ways. The AI Visibility Index is a ready-made database of more than 448 million monthly prompts, modeled from searches in Ahrefs' keyword data, so you can look up any brand without setting anything up.

Custom Prompts tracks the questions you define. Paid Ahrefs plans already include some: Lite comes with 150 checks a month, which is 5 prompts a day on one platform.

Ahrefs is candid about the index's limit. It says coverage may be limited for brands with little or no search volume.

Pick something else if you are a young brand with few branded searches. Start with custom prompts instead, in Ahrefs or in a dedicated tracker.

HubSpot AEO

Best for: small teams that want one flat price, especially if HubSpot already holds their marketing data

Engines: ChatGPT, Gemini, and Perplexity

Price as listed: $50 a month, or $45 a month paid annually, for 25 prompts

HubSpot's AEO tool is the easiest of the eight to budget. One price covers 25 prompts on three engines, and you can buy more prompts at any time.

It gives you four things: a visibility score, prompt tracking, citation analysis, and prioritized recommendations. It also suggests prompts from your company, competitors, and industry, which helps a team that has never written a prompt set.

HubSpot says the recommendations get more specific with Marketing Hub Pro and Enterprise, because your CRM data is already connected.

Pick something else if Google's AI Overviews or AI Mode matter to you. Neither is on the engine list.

AI Search Tools Comparison Table

Read the last two columns together. SE Visible's entry plan costs more than Otterly's and carries more than ten times the prompts.

Which AI Search Tool Fits Your Team?

The right tool depends on who reads the dashboard and who acts on it. Check your GA4 referral report first: it shows which AI engines already send you visits, and those are the engines to insist on.

You run an SEO agency with several clients: look at SE Visible, Otterly, and Peec AI first. SE Visible lists multiple brands and unlimited users, Otterly's partner program adds pitch workspaces and branded reports, and Peec AI has separate agency pricing. If you would rather offer the service than run the tooling, see the AI SEO for agencies page.

You lead growth at a SaaS company: the question is whether your team has time to act on the data. If it does, Peec AI's unlimited users or HubSpot AEO beside your CRM both fit. If it does not, a dashboard adds a report and no result.

You are a small team without an analyst: start flat and small. HubSpot AEO at $50 a month or Otterly Lite at $29 a month gives you a number to watch while you learn which prompts matter.

You are enterprise and need compliance: Profound lists SSO/SAML and SOC 2 on its Enterprise plan. Otterly and Peec AI list single sign-on on theirs, and Semrush's enterprise offer lists SSO and audit logs.

You already pay for an SEO suite: use what is included before you add a vendor. Ahrefs plans come with free checks, and Semrush's toolkit bolts onto an existing subscription.

You want to test before spending anything: The free AI SEO audit tool runs on any URL with no signup and shows you citation-readiness issues on your most important pages. Profound's free plan also gives you seven days of data on 50 prompts.

How Accurate Are AI Search Tools?

They are as accurate as their sample is large. AI engines do not give the same answer every time, so one run of a prompt tells you little.

We measured this on our own tracking data: 96,720 AI answers, collected from June to September 2026. Across the 368 prompts that ran ten times or more, the brand named most often for a prompt appeared in 50.9% of that prompt's runs.

In the other half, that brand was missing from the answer. A tool that checks a prompt once a week can report swings that are only noise.

That makes three checks worth running on any tool before you commit:

• Open the raw answers. If you cannot read the answer behind a score, you cannot tell a real change from a wording quirk.
• Count the runs behind a figure. A visibility score built on 30 runs of a prompt means more than one built on 4.
• Run ten prompts by hand. Compare what you see in the engine with what the tool recorded for the same week.

Once the sample is sound, AI search share of voice is the metric to watch over time.

Where RankZero Fits, and Who Should Pick Another Tool

RankZero is an agency first. We do the AI SEO work for SaaS and ecommerce brands, and our own software is the engine behind that work and the proof of it.

The engine tracks your prompts on ChatGPT, Perplexity, Google AI Overviews, and Gemini as standard, with Claude on request. It records brand mentions, cited URLs, sentiment, and share of voice against your competitors, and it connects to GA4 and Search Console.

It also audits pages one by one for citation readiness. The free AI SEO audit tool runs on any URL with no signup.

Pick one of the eight tools instead if any of these is true:

• You want a dashboard to run yourself, and you have people with time to act on it.
• You need Microsoft Copilot or Google AI Mode tracked. Otterly, SE Visible, and Ahrefs cover them, and we do not track them as standard.
• You only need a visibility number for a monthly report. HubSpot AEO or Otterly Lite does that at a flat monthly price.
• Procurement needs SOC 2 and SSO on a published plan page. Profound lists both.

We are the better fit when the gap is the work, not the data. We find the prompts you lose and why, rebuild the pages that should win them, fix what blocks AI crawlers, and earn mentions on the sites the engines already cite.

Retainers are scoped and quoted on a call, so there is no price to compare in the table above. Get your AI search audit and you will see your citation share against your top three competitors.

FAQ

What is the best AI search tool?

There is no single best AI search tool, because the eight are built for different buyers. Profound suits enterprise teams, Otterly and HubSpot AEO suit small budgets, SE Visible and Peec AI suit agencies and larger teams, and Semrush and Ahrefs suit teams already inside those suites. Choose on engines, answers per month, and who will act on the data.

Are AEO tools and AI search tools the same thing?

Yes. AEO tools, AI search tools, and AI visibility tools are three labels for software that tracks how AI engines name and cite your brand. HubSpot and Profound use AEO, Semrush and SE Visible use AI visibility, and Otterly and Peec AI use AI search. The features overlap almost completely.

How much do AI search tools cost?

On 2 October 2026, published entry prices ran from $29 a month for Otterly Lite to $99 a month for SE Visible Basic and the Semrush toolkit. Mid plans sit near $189 a month at Otterly, AIclicks, and SE Visible. Enterprise plans are custom everywhere. Compare by answers per month, since prompt counts and engine lists differ.

What is the best AI search tool for agencies?

Agencies should shortlist tools with separate client spaces and no per-seat cost. SE Visible lists multiple brands and unlimited users, Otterly offers unlimited workspaces from Standard plus an Agency Partner program, and Peec AI has separate agency pricing. Ask each one how reports can carry your own branding.

Do I need an AI search tool if most of my traffic still comes from Google?

A tool is worth it once AI answers influence your buyers, even if the clicks are still small. An AI answer can shape a shortlist without sending a single click, and that never shows up in Search Console. A free AI SEO audit shows where your pages stand today without any cost or commitment.

How quickly do changes show up in an AI search tool?

Content changes typically show up in tracking within two to four weeks, depending on how quickly the engines re-crawl the page. Earning mentions on other sites takes longer. The fastest diagnostic is the free AI SEO audit, which identifies the highest-impact fixes on your existing pages before you change anything.

Pick the Unit First, Then the Tool

Start with three numbers: how many prompts your buyers ask, which engines they ask them in, and how often you need a fresh reading. Multiply them, and you have the answers per month you are shopping for.

Then shortlist two tools from the table and run the same 20 prompts through both for two weeks. The one whose raw answers match what you see by hand is the one to keep.

If you want to see where your site stands before choosing a platform, the free AI SEO audit runs in under a minute on any URL with no login.

If you would rather have the gap closed than charted, book an AI search audit call. We will show you where your brand sits in the answers your buyers are reading, and what it takes to move it.
