12 Best Answer Engine Optimization Tools (2026)

The AEO tool market grew from ~3 products in early 2024 to 30+ by mid-2026.¹ Most of them are SEO tools with an AEO module bolted on. A few are purpose-built. This post compares the 12 answer engine optimization tools I'd actually consider, with honest takes on where each one wins and where it doesn't. I've built the tooling that tracks brand mentions across 9 AI engines — ChatGPT, Claude, Gemini, Perplexity, Copilot, DeepSeek, Grok, Google AI Overviews, and Google AI Mode — and I talk to people shopping for this every week, so this is the buyer's-guide version I wish existed when I started.

Example: ChatGPT (logged out) ranking AEO tools, with its reasons for each. This is how buyers discover tools now.

Disclosure: FixAEO is our product, and it's listed first. I've kept the comparison fair — including pointing out where competitors are stronger for specific use cases. If you want zero-bias coverage, also check the G2 AEO Software grid.

What to look for in an AEO tool

Before the comparison, here's the framework. A serious AEO tool should at minimum do five things:

1. Heuristic audit — schema, robots.txt, llms.txt, OpenGraph, FAQ structure, sitemap
2. Live LLM brand recognition — actually ask ChatGPT/Claude/Copilot/Gemini about your brand
3. Prompt tracking — monitor a set of buyer-intent prompts over time
4. Competitor benchmarking — see how you stack up against named competitors
5. Actionable fixes — not just a score, but a ranked list of what to change

Bonus features that matter at scale:

• API access for integrating into your own dashboard
• Daily/weekly automation rather than on-demand scans
• White-label reporting (for agencies)
• Citation tracking (which third-party sources feed AI answers about you)

Example: the domains AI engines cite most in InsiteChat's category — FixAEO's citation-source view.

Answer engine optimization tools compared

Here's the whole field in one table before the write-ups. "Engines covered" is the number of AI engines each tool tracks by default. "Free tier" means usable without paying — a time-limited trial is not a free tier. Where a vendor doesn't publish a number, I've written "not published" rather than guess.

Tool	Engines covered	Entry price	Free tier
FixAEO	6 (9 on Enterprise)	$29/mo ($25 annual)	Yes — 22 free tools + Gemini scan, plus a 7-day Lite trial
Profound	8	~$100/mo	No
Peec AI	3 (add-ons for more)	from €89/mo (~$95)	No — 7-day trial
Otterly.ai	6	$29/mo	No — 14-day trial
RadarKit	6 (no Claude, Grok, or DeepSeek)	$29/mo	No
AthenaHQ	8	$295/mo ($95 annual)	Free Essential tier
SearchFit	6 (per their tagline; unverified)	not published	not published
AEO Engine	4	$1,597/mo (done-for-you)	No
AEO Checker	not published	$5/mo	Yes — free scanner
xFunnel	9 (2 more coming soon)	Custom (enterprise)	Yes — one-time 50-query audit
Rankscale	9–10 distinct ("17+" counts GUI+API twice)	$20/mo	No — paid trial
Authoritas AEO	not published	~$500/mo	No

Prices are entry-tier and change often. Treat the table as a starting point and verify on each vendor's pricing page. Now the tool-by-tool breakdown.

The 12 tools, ranked by fit

1. FixAEO

Best for: indie founders, indie marketers, and small teams who want fast, useful audits without committing to a $99+/mo tool.²

FixAEO is our product, so read this section knowing that. The model that makes it work: free for daily heuristic scans and 22 utility tools, with paid tiers unlocking multi-engine LLM queries and automated tracking. The free tier is genuinely free — a Gemini-powered scan and the full tool catalog, no card on file, no signup. Lite is $29/mo, or $25/mo billed annually, and covers 6 engines with auto-rescans every 72 hours; Growth is $79/mo ($68/mo annually) and steps that up to daily rescans, 5 brands, and 50 tracked prompts. Both monthly plans include a 7-day free trial (card required, you're charged when it ends unless you cancel).

The differentiator is price and honesty of the free tier. Most tools in this list gate everything behind a trial or a sales call. We put a real scan and a 22-tool catalog in front of you with zero friction. Scans run in a few seconds, the scoring methodology is published, and the API is free.

The honest limitation: there are no agency-team seats yet, no deep citation graph like Authoritas builds, and no in-editor content writer like Frase. If you manage 20 client brands or need enterprise SSO, we're not the pick today.

Who it's for: sub-$1M/mo MRR SaaS, indie founders, and anyone who wants to know where they stand before paying anyone. Run a free scan, or open the full AEO audit tool for the detailed checklist behind every scan.

2. Profound

Best for: brands tracking sentiment over time across many AI engines.

Profound's wedge is sentiment analysis. They go deeper than "are you mentioned?" into how AI engines talk about you. That makes it useful for PR-conscious brands and reputation monitoring where the tone of the mention matters as much as the mention itself. Their positioning leans toward "AI engineer" teams that want full-stack automation rather than a quick self-serve audit.

The limitation is the flip side of that depth: heuristic site auditing is thin, and there's no free tier, so you can't kick the tires without a conversation. Entry pricing sits around $100/mo and climbs from there.

Who it's for: funded brands with a comms function that cares about share-of-voice and sentiment, not just presence. See the full head-to-head: FixAEO vs Profound.

3. Peec AI

Best for: European teams that want a clean AI-visibility analytics dashboard.

Peec AI is a well-built analytics tracker popular in Europe, priced in euros from €89/mo (roughly $95). It covers 3 engines by default — ChatGPT, Perplexity, and Google — and treats additional engines as paid add-ons on top of the base plan. So the wider coverage is reachable, but the entry cost climbs engine by engine.

The differentiator is a polished, data-pipeline-style product for teams that want visibility numbers feeding into their own reporting. The limitation is that it's paid-only. There's a 7-day trial but no free forever tier, and the default 3-engine scope is narrow next to tools that ship 8.

Who it's for: European marketing teams with budget who want analytics depth over breadth. See the full head-to-head: FixAEO vs Peec AI.

4. Otterly.ai

Best for: marketing teams that want a turnkey "AI search ranking" dashboard.

Otterly was one of the earliest in the space (mid-2023). Mature product, clean UI, leans heavily on Perplexity and ChatGPT tracking, and covers 4 core engines (Gemini, Google AI Mode, and Claude are paid add-ons). Pricing runs $29/$189/$489/mo across three tiers after a 14-day free trial.

The differentiator is maturity — the dashboard and mention tracking are accurate and battle-tested. The limitation is less depth on the technical side: schema and llms.txt auditing is lighter than a purpose-built audit tool, and the free trial expires rather than converting to a free tier.

Who it's for: marketing teams that value a proven dashboard and don't need heavy heuristic auditing. See the full head-to-head: FixAEO vs Otterly.

5. RadarKit

Best for: teams that want broad engine coverage including the newer models at a mid-market price.

RadarKit covers 6 surfaces — ChatGPT, Copilot, Gemini, Perplexity, Google AI Overviews, and Google AI Mode. It skips Claude, Grok, and DeepSeek, three engines FixAEO does track. Pricing runs $29 (2 projects, 15 prompts), $79 (5 projects, 50 prompts), and $139/mo (10 projects, 100 prompts).

The differentiator is engine breadth at a reasonable price point and multi-project support. The limitation is there's no free tier, so the $29 entry is the floor for trying it at all.

Who it's for: growing teams tracking a handful of brands who want the newer engines covered. See the full head-to-head: FixAEO vs RadarKit.

6. AthenaHQ

Best for: enterprise teams that want a dedicated GEO specialist alongside the tool.

AthenaHQ is the enterprise end of the field. It covers 8 engines on a credit-metered system, with a limited free "Essential" tier (300 credits/mo, 5 models) and a $295/mo floor ($95/mo effective if billed annually) above it. The pitch pairs the software with a dedicated specialist, so you're buying a service wrapper as much as a dashboard.

The differentiator is the white-glove, done-with-you model — good if you want a human accountable for the program. The limitation is the price floor and the credit metering: this is not a tool you spin up for a quick check, and the $295/mo entry rules out most sub-enterprise buyers.

Who it's for: funded companies that want enterprise GEO with a specialist attached. See the full head-to-head: FixAEO vs AthenaHQ.

7. Rankscale

Best for: teams wanting an AI-search rank tracker with a familiar SEO-tool feel.

Rankscale frames AI visibility like a classic rank tracker — score, position, movement over time — which makes it approachable for teams migrating from traditional SEO tooling. It's a newer entrant positioning itself as a straightforward AI-search monitor rather than a full audit-plus-content suite.

The differentiator is the familiar rank-tracker mental model, which lowers the learning curve for SEO teams. The limitation is that a rank-tracker framing can under-serve the audit and fix side of AEO — knowing you dropped is only half the job; you still need the ranked list of what to change.

Who it's for: SEO teams who think in rankings and want AI visibility in the same shape. See the full head-to-head: FixAEO vs Rankscale.

8. SearchFit

Best for: teams that want an integrated stack and don't mind a gated product.

SearchFit says it scans six engines — their own tagline's count, which I can't independently verify because their site blocks crawlers — and positions itself for the engineer-in-your-stack buyer who wants integrations wired in. It's built as a fuller platform rather than a quick audit.

The honest limitation: I can't tell you what it costs, because SearchFit's pricing page returned a 403 to our checks³ — it blocks bot user-agents wholesale, which is why the table says "not published." That same bot-blocking is a strategy question for an AEO product, since AI crawlers are bots too. If pricing transparency and open access matter to you, that's a real difference.

Who it's for: teams comfortable with a gated dashboard and a sales conversation to learn pricing. See the full head-to-head: FixAEO vs SearchFit.

9. AEO Engine

Best for: brands that want done-for-you AEO and have the budget for a retainer.

AEO Engine isn't a self-serve tool — it's a done-for-you agency service with software attached. It covers 4 engines, and pricing runs $1,597/mo (Scale $2,997, plus Enterprise) with a 90-day commitment, so the effective minimum spend is around $4,791.

The differentiator is that a human team executes the work — content, entity presence, technical fixes — not just reports it. The limitation is obvious: this is an agency budget, not a tool budget, and the 4-engine coverage is narrower than the self-serve trackers. It's a different category of buy.

Who it's for: funded brands that want to outsource the whole program. See the full head-to-head: FixAEO vs AEO Engine.

10. AEO Checker

Best for: budget-conscious teams that want a cheap multi-language scanner.

AEO Checker is the low-cost entrant. It doesn't publicly list which engines its scanner queries, but it's available in 8 languages and starts at just $5/mo, climbing to $55/mo on higher tiers. There's a free scanner up front, so you can check a URL before paying.

The differentiator is price and language coverage — nothing else here starts at $5, and multi-language matters if your buyers search in more than English. The limitation is that the very cheap entry tier is thin; the broader toolkit and daily tracking that most teams actually need sit on the higher plans.

Who it's for: solo operators and multi-language sites doing spot checks on a tight budget.

11. xFunnel

Best for: enterprise teams evaluating a heavily-funded AI-search analytics platform.

xFunnel is an enterprise-oriented AI-search analytics product that HubSpot bought for roughly $30 million in late October 2025, per HubSpot's own SEC filing. It covers 9 AI surfaces — ChatGPT with and without browsing, Gemini, Claude, Perplexity, AI Overviews, AI Mode, Copilot, and Grok, with Meta AI and DeepSeek marked coming soon — and offers a free Starter tier — but that's a one-time audit capped at 50 queries, not an ongoing free plan. Beyond that, pricing is "Custom" enterprise, which means a sales call.

The differentiator is enterprise-grade analytics and the credibility of major-vendor attention. The limitation is the "custom" pricing wall and the one-shot free audit: you can't run repeatable free scans, and you can't see the cost without a conversation.

Who it's for: enterprise teams that want a funded analytics platform and are comfortable with custom pricing. See the full head-to-head: FixAEO vs xFunnel.

12. Authoritas AEO

Best for: enterprise SEO teams already on the Authoritas platform.

Authoritas added an AEO module on top of their long-running SEO product. The advantage: it integrates with their existing rank tracker, so you can see SEO position and AEO Visibility Score in one dashboard, backed by a genuine citation-source graph and a large prompt library.

The disadvantage: pricing assumes you're already a customer. Standalone AEO use is expensive — roughly $500/mo and up — and the learning curve is steep. It's overkill for sub-$1M ARR companies.

Who it's for: enterprise SEO teams that already live in Authoritas and want AEO in the same pane.

Honorable mentions: Brand24, Mentionlytics, and Frase

Brand24 and Mentionlytics, from earlier versions of this list, still deserve a line — and Frase earns one from the content side. Brand24 bolted an AI-mention module onto its social-listening platform — if you already pay for Brand24, the alerting and sentiment infrastructure translate well, but it isn't a purpose-built AEO tracker. Mentionlytics is the cheaper, agency-oriented cousin: solid mention tracking across client brands, basic on the audit side.

Frase pivoted from SEO content generation to including AEO scoring. It's a content tool first, not a monitoring tool, so it doesn't fit cleanly in the ranking — but it's worth knowing about. It scores your draft for AEO fit while you write, with GPT-driven outline generation, priced $44–$179/mo, or from $39/mo billed yearly. The limitation is thin live LLM brand recognition; the audit side is mostly heuristic. Useful if your content workflow already lives in Frase.

AEO tools vs AEO services

A tool hands you the dashboard and the fixes; you do the work. A service does the work for you. Most of this list is tools. AEO Engine and AthenaHQ blur into the service side (a human team or a dedicated specialist), which is why they cost 10–50x a self-serve tracker.

The right choice comes down to time and budget. If you have someone in-house who can act on a ranked fix list, a $29/mo tool beats a $1,597/mo retainer every time. If you don't, paying for execution can be worth it. I wrote the full tradeoff — DIY, agency, or self-serve tool — in the answer engine optimization services buyer's guide.

Which one should you pick?

A decision matrix by stage:

You are…	Pick
An indie founder doing first AEO audit	FixAEO Free — start with one scan, see where you stand
A 5-50 person SaaS, $10K-100K/mo MRR	FixAEO Lite or Profound
A growth-stage SaaS, $100K-1M/mo MRR	FixAEO Lite or Profound + Frase for content
A marketing team at an enterprise	Authoritas (if you're already on their SEO stack) or AthenaHQ
An agency tracking 10+ client brands	Authoritas Agency or RadarKit for multi-project
A comms team focused on sentiment	Profound
A multi-language site on a tight budget	AEO Checker
A team that wants execution done for you	AEO Engine or AthenaHQ

The one thing none of these tools can do

Pick the right prompts to track. This is the single hardest part of AEO measurement — knowing what your buyers actually ask AI assistants. Every tool listed above tracks the prompts you feed it; none will tell you the right starting list.

Three rules:

1. Reformulate your top 10 SEO keywords as questions. "Best CRM" → "What is the best CRM for a 5-person team?"
2. Add 5 problem-statement prompts. "I'm overspending on CRM software, what should I do?"
3. Add 5 comparison prompts. "X vs Y" — including your direct competitors.

That's a starter list of 20. Refine quarterly. If you're still deciding whether to pay for a tool at all, see AEO services vs doing it yourself with tools for the tradeoffs.

What we won't tell you

This is a buyer's-guide post and we are one of the tools. So one honest disclaimer: most AEO tools will tell you the same handful of things on your first scan. The real differentiator over months is whether the tool keeps tracking the right prompts and surfaces changes — that's where you find the moments where your competitor just earned a Wikipedia mention and your Visibility Score quietly dropped 8 points.

That tracking work is where AEO tools earn their subscription. The one-time audit is almost commoditised.

FAQ

Are AEO tools worth paying for?

Yes, if you have an active brand to defend. The 30-second scan is free everywhere. The week-over-week tracking is the paid value.

How much do AEO tools cost in 2026?

It ranges wildly. The cheapest self-serve entry is around $5/mo (AEO Checker); most mainstream trackers land in the $29–$129/mo band (FixAEO, Otterly, RadarKit, Peec AI). Enterprise tools like AthenaHQ start at $295/mo, and done-for-you services like AEO Engine run $1,597/mo and up. A few — SearchFit, xFunnel — don't publish a public price at all. For a solo founder, budget $0–$29/mo. For an enterprise with a comms team, expect $100–$500/mo. For fully outsourced work, four figures a month.

Do I need an AEO tool if I already have Semrush/Ahrefs?

Different jobs. Semrush and Ahrefs tell you where you rank on Google's results page. An AEO tool tells you whether ChatGPT, Claude, Perplexity, and the rest actually name your brand inside their answers — which is a different question with different sources feeding it. Some SEO suites are bolting on AEO modules, but they're thin next to purpose-built trackers. If AI traffic matters to you, keep the SEO tool for rankings and add a lightweight AEO tool for citations. You don't have to spend much — a free tier covers the audit.

Can I do AEO without a tool?

Partially. You can manually audit robots.txt, schema, llms.txt, and check a few prompts on ChatGPT yourself, and the AI SEO tools for doing the work faster can speed up the classic-SEO half of that. But tracking change over time across N engines manually is a 4 hour/week job — usually cheaper to pay $29/mo than burn that time.

Why is FixAEO so much cheaper than the others?

Two reasons: we charge less because our infra is leaner (Cloudflare Pages + Go on a $0/mo VM, not AWS Enterprise), and we're newer. Once we have agency-team feature parity, expect prices to move.

Will Google's AI Overviews replace these tools?

No. AI Overviews are one engine of many. AEO tools track across ChatGPT, Claude, Copilot, Gemini, Perplexity, Grok, and DeepSeek — Google AI Overviews is a slice. For the full rundown, see the best AI search engines.

Does the engine list matter?

Yes — but maybe less than you'd think. We've found correlation between Visibility Scores across major engines is ~0.7. Sites that rank well in one usually rank decently in others. Track at least 3 engines; tracking all 9 is diminishing returns unless you're a comms team.

In one paragraph

The AEO tool market has matured fast — 12 tools worth knowing, from a $5/mo scanner to a $1,597/mo service. Pick FixAEO if you want the cheapest, most-transparent free-tier audit and you're sub-$1M/mo MRR. Pick Profound if sentiment depth matters more than heuristic auditing. Pick Authoritas or AthenaHQ if you're enterprise. Pick AEO Engine if you want the work done for you. Start with a free FixAEO scan — 30 seconds, no signup, and you'll know exactly where you stand before paying anyone anything.
