7 Best AEO Tools for Answer Engine Optimization in 2026

Updated · VibeSEO Editorial Team

Answer engine optimization starts from questions: the ones your customers type into ChatGPT or Google and now get a written answer to. An AEO tool tracks those questions, shows whether the answers name you and why, and checks that answer engines can read the pages that should be quoted. These seven tools approach it from different angles.

The short answer

Pick VibeSEO if you want your own questions checked daily on ChatGPT, Gemini, AI Overviews and AI Mode with every answer saved and an audit of AI crawler access, from $189/mo. Pick Otterly.AI for a low-cost start, Ahrefs Brand Radar to benchmark a whole niche without setup, and AthenaHQ if you want to try a free plan first.

What matters most

  1. 01

    Your questions, not only an index

    Pre-built prompt indexes are great for benchmarking, but AEO is won on the specific questions your buyers ask. Make sure you can track your own, without your brand name in them.

  2. 02

    Read the answers

    The answer text shows why a competitor was chosen: the source it quoted, the claim it repeated. Tools that keep full answers make that visible.

  3. 03

    Answer readiness

    Engines quote pages they can fetch and parse. An AEO tool should check crawler access and page readability, not just count mentions.

Our pick

1. VibeSEO

Best for: tracking your buyers' questions on four engines

VibeSEO suggests the questions your buyers ask, without your brand name in them, and checks them on ChatGPT, Gemini, Google AI Overviews and Google AI Mode every day. Each answer is saved with the brands it named and the sources it cited, and the GEO Audit shows whether AI crawlers can fetch and read the pages you want quoted.

What stands out

  • All four engines on every plan, each reported separately with no averaged score
  • Every answer saved in full, with the brands it named, in order, and the sources it cited
  • Official Claude connector, official ChatGPT app and MCP server; SEO tools and articles on the same account

Keep in mind

Four engines only: Perplexity and Claude are not monitored as answer engines. GEO Pro costs $189/mo, more than the entry plans of the smaller trackers.

2. Otterly.AI

Best for: small teams starting prompt tracking cheaply

Otterly.AI is the lowest-priced of the established trackers. It monitors your prompts on ChatGPT, Google AI Overviews, Perplexity and Copilot out of the box, adds other engines as small add-ons, and includes GEO audits of your URLs on every plan.

What stands out

  • Lowest entry price among the established trackers
  • GEO URL audits included, even on the entry plan
  • Unlimited team members and brand reports

Keep in mind

Google AI Mode, Gemini and Claude cost extra per engine, the entry plan tracks only 15 prompts, and MCP and API access start on the $189 Standard plan.

3. Ahrefs Brand Radar

Best for: Ahrefs users benchmarking a whole niche

Ahrefs Brand Radar starts from an index of hundreds of millions of prompts, so you can see any brand's AI visibility without setting anything up, and ties mentions back to search demand from Ahrefs' keyword data. Custom prompt tracking is included from the Lite plan and metered per check.

What stands out

  • A ready-made prompt index: benchmark any brand with no setup
  • AI mentions tied to real search demand from Ahrefs' keyword database
  • Also covers YouTube, TikTok and Reddit visibility

Keep in mind

The index is refreshed monthly; daily numbers need custom prompts, which are metered per check on top of an Ahrefs subscription.

4. AthenaHQ

Best for: teams wanting tracking plus an optimization agent

AthenaHQ has a genuinely free tier across five engines and covers eleven models on its first paid plan. On top of tracking it offers a content optimization agent and manages robots.txt and llms.txt for you.

What stands out

  • A free plan covering five engines
  • Eleven models on the first paid plan, unlimited seats
  • Content optimization agent plus robots.txt and llms.txt management

Keep in mind

A big jump from the free plan to $295/mo, and API access costs extra on the Starter plan.

5. Scrunch

Best for: mid-market brands optimizing for AI agents

Scrunch tracks large industry prompt sets by persona and adds an Agent Experience Platform that serves a compressed, machine-readable version of your pages to AI agents. Agent traffic monitoring and page audits are on every plan.

What stands out

  • Persona-based prompt tracking with large industry prompt sets
  • Serves an agent-readable version of your site
  • Agent traffic monitoring and page audits on all plans

Keep in mind

The highest entry price of the self-serve plans here, with three seats on Starter.

6. Peec AI

Best for: marketing teams wanting polished daily analytics

Peec AI is a dedicated AI visibility tracker priced by prompts and models, with unlimited users on every plan. Beyond visibility and sources it checks how AI describes your brand against facts you set, and tracks shopping results and sponsored placements inside answers.

What stands out

  • Unlimited users on every plan; extra countries and languages cost nothing
  • Brand perception with fact-checking of AI claims against your own facts
  • AI shopping tracking and a library of ads shown inside answers

Keep in mind

Self-serve plans include three models of your choice; every further engine is a paid add-on, and the API is Enterprise only.

7. SurfacedBy

Best for: small businesses wanting tracking plus fixes

SurfacedBy tracks AI visibility per domain and, from its Professional plan, acts on it: it drafts briefs and articles published to WordPress or Shopify, drafts community replies, runs outreach, then re-measures. GA4 attributes AI traffic to revenue.

What stands out

  • Track, act and re-measure in one loop from $99/mo
  • Drafts published to WordPress or Shopify
  • Per-prompt country targeting on every plan

Keep in mind

A small, founder-led product; the entry plan covers only ChatGPT, Perplexity and Gemini and has no action credits.

How to choose

How we ranked them

We ranked the tools on how well they support the AEO loop: tracking your own questions, reading the full answers and their sources, checking that answer engines can read your pages, and pricing that scales with a realistic question set. Prices and plan details were read on each vendor's own pricing page on the date shown on its card.

VibeSEO is ranked first for question tracking with full answers and a crawler audit on the engines most buyers use. If you need Perplexity, Copilot or Claude as answer engines, the tools further down cover them.

Common questions

What is AEO?

Answer engine optimization is the practice of making your brand and pages the ones AI answer engines quote when people ask a question. It covers tracking those answers, publishing clear pages that answer the question, and making sure answer engines can read them.

Is AEO the same as GEO?

Mostly. AEO usually refers to answer engines and question-shaped queries, including featured snippets and voice answers; GEO is the broader term for generative AI search. The tools on this list serve both.

Should my tracked questions include my brand name?

Mostly no. Asking "what is the best X for Y" shows whether AI brings you up unprompted, which is what a buyer sees. Branded questions are useful separately, to check what AI says about you.

How many questions should I track?

Twenty to fifty well-chosen questions across your main topics are enough to see a trend for most small and mid-sized businesses. Larger programmes track hundreds, which is where per-prompt pricing adds up.
