Best AEO tools 2026: nine platforms, one standard

Every AEO tool answers one of two questions. Most answer: where does my brand appear in AI answers? Only the engineering layer answers: why, and what do we ship to change it? Here are nine tools, what each is genuinely for, what each costs as of August 2026, and who should buy it.

How to read this page.

We sell one of these nine tools. Every claim about the other eight is dated and sourced at the foot of the page, because a comparison you cannot verify is an ad. Where a competitor is ahead of us, we say so in specifics.

The nine

What each tool is actually for.

01ProfoundFull comparison

From $99/mo billed yearly (ChatGPT only). The real floor for most teams is $399/mo.

The category leader in AI answer monitoring: Prompt Volumes demand data and Agent Analytics CDN-log crawler analytics.

Strong at: Answer-side observation at enterprise scale. $155M raised, 700+ enterprises, the deepest engine coverage in the category.
Does not do: Does not probe the live fetch, and does not ship or re-verify engineering fixes. Logs describe visits that already happened.
Buy it if: You need answer-side observation at enterprise scale.

02Peec AIFull comparison

From ~€85/$95 per month. 7-day trial, no credit card.

The cleanest rank-tracking dashboard in the category, captured from real browser sessions across five engines.

Strong at: UI quality, 115+ languages with regional benchmarking, unlimited seats on every plan, transparent pricing.
Does not do: No raw-vs-rendered diff and no shipped fixes. Its Crawlability feature reads server logs after the visit.
Buy it if: You want the cleanest daily scoreboard across many markets.

03Scrunch AI

~$250/mo entry per one 2026 source; sales-led beyond that.

An enterprise AXP that audits your pages the way an AI user agent experiences them, with SOC 2 for procurement.

Strong at: Enterprise readiness and a page-audit orientation that takes the agent experience seriously.
Does not do: Does not publicly offer a live two-fetch diff or a verified-fix loop. Pricing is sales-led.
Buy it if: You are enterprise, need SOC 2 today, and want audit-style reporting.

04Athena HQ

Free Essential tier; Starter $295/mo.

A YC W25 platform from ex-Google Search founders, with an agentic Action Center on top of monitoring.

Strong at: A free Essential tier to start, a $295 Starter plan, and a team that knows search internals.
Does not do: Capture methodology is undisclosed, and the product promotes smart robots.txt and llms.txt, which are not citation levers on current evidence.
Buy it if: You want a free entry point from a pedigreed team.

05Otterly.aiFull comparison

From $29/mo. Gemini, AI Mode, and Claude are paid add-ons on Lite.

The cheapest credible AI search monitoring: prompts, mentions, and citations across the major engines.

Strong at: Price. $29/mo Lite, bootstrapped, a Gartner Cool Vendor 2025, an MCP server, and a public API.
Does not do: Monitoring only. No crawl layer, no diff, no fixes, no verification.
Buy it if: You want the cheapest credible scoreboard and nothing more.

06Ahrefs Brand Radar

Free tier; ~$828+/mo all-in at scale.

The largest prompt database in the category: ~356M+ search-backed prompts inside the Ahrefs suite.

Strong at: Research depth. A free tier to explore, and the May 2026 schema study we cite across this site.
Does not do: It is a research database, not an execution layer. Nothing ships and nothing re-verifies.
Buy it if: You need prompt-demand research more than you need fixes.

07Semrush AI Toolkit

$99/mo per domain, on top of a Semrush subscription.

A $99/mo per-domain add-on to the Semrush suite, with 261M+ prompts and an AI Search Health widget.

Strong at: Convenience for existing Semrush customers; the Health widget does baseline crawlability checks.
Does not do: Baseline checks are not a two-fetch diff, and the toolkit does not ship or verify fixes.
Buy it if: You already pay for Semrush and want AI visibility in the same bill.

08Evertune

Enterprise pricing, sales-led.

Panel-based measurement science from ex-Trade Desk founders, polling 1M+ prompts per brand per month.

Strong at: Statistical rigor. The strongest methodology story on the measurement side.
Does not do: No crawl layer at all. It measures perception, not what agents can fetch.
Buy it if: You are a large brand buying measurement science for planning.

09Bull AI Labs

From free. Proof is never gated; only remedy is paid.

The engineering layer. A live two-fetch diff across 10 crawler user agents and three classes, 51 severity-weighted signals, and a ship-and-re-verify loop.

Strong at: We fetch your pages as the agents themselves, find what they could not read, ship the engineering fix, and re-probe until it verifies. The full diagnosis is free.
Does not do: We do not match Profound’s answer-side observation scale. Saying that plainly is the point of this page.
Buy it if: You need the fetch fixed, not just observed.

The standard

The question that sorts all nine.

Ask any tool on this page, including ours: does it tell you what the agent could read, or only that it visited or answered? A two-fetch diff loads your page twice in the same second - once as a browser that runs JavaScript, once as an AI agent that does not - and diffs the two responses word for word. That diff is the entire engineering question, and only one tool on this page runs it.

FAQ

Questions buyers actually ask.

What is the best AEO tool in 2026?

It depends on the layer you need. For answer monitoring at enterprise scale, Profound is the most mature. For the cheapest credible monitoring, Otterly.ai starts at $29 a month. For engineering the fetch itself, finding what AI agents cannot read and shipping the verified fix, that is Bull AI Labs, and the diagnosis is free.

What is the cheapest AEO tool?

Otterly.ai Lite at $29 a month is the cheapest credible paid monitoring. Ahrefs Brand Radar and Athena HQ both offer free tiers for research and basic tracking. The Bull AI Labs audit is free and is the only free option that tests what AI agents can actually fetch on your pages.

Is there a free AEO tool?

Yes, three kinds. The Bull AI Labs audit is a free full diagnosis: two-fetch diff, competitor citations, and engineering findings on your own domain. Ahrefs Brand Radar has a free research tier. Athena HQ has a free Essential plan. Only the first tests the fetch itself.

What is the difference between AEO monitoring and Engineered AEO?

Monitoring tells you where your brand appears in AI answers and how that moves over time. Engineered AEO works one layer down: it fetches your pages the way AI agents fetch them, diffs raw against rendered, finds what the agent could not read, ships the engineering fix, and re-probes until the fix verifies.

Do any AEO tools fix technical issues?

Almost none. Most stop at reports, scores, or recommendation lists. Scrunch AI audits crawlability and Semrush runs baseline checks, but neither ships fixes. Bull AI Labs is built around the ship-and-re-verify loop: a fix closes only when a re-probe confirms what the agent receives actually changed.

How do I test if AI can read my site?

Run a two-fetch diff: load the same URL as a browser that executes JavaScript and as an AI agent that does not, then compare what each received. The free Bull AI Labs audit runs this across ten crawler user agents on your own pages, with no signup required.
