Best AEO Tools (Answer Engine Optimization) in 2026
The short answer
The best AEO tools probe live AI engines with real buyer questions and report whether you're cited, mentioned, or absent — then audit why. cited? is the strongest free option for diagnosis and audits; Otterly.ai, Profound, and Peec AI lead for ongoing monitoring. Classic suites like SEMrush and Ahrefs add AI features but aren't AEO-first.
What makes a good AEO tool?
- ▪Probes live AI engines (ChatGPT, Perplexity, AI Overviews), not just crawls HTML.
- ▪Reports cited / mentioned / absent and competitor share of voice.
- ▪Generates buyer questions from your site, not only prompts you type.
- ▪Audits crawler access, extractability, schema, and trust.
- ▪Samples repeatedly, since AI answers vary run to run.

Free vs paid — which do you need?
Start free to diagnose: a scanner tells you today whether you're cited and what's blocking you. Add a paid monitor when you need continuous tracking across many prompts and engines. Most teams run both layers.
Where to start
cited? gives a free baseline — it generates your buyers' questions, probes live engines, scores visibility, names who's cited instead, and ships a fix prompt per failed check. Run it before committing to any paid platform.
Frequently asked questions
+What is the best free AEO tool?
cited? is a strong free choice: it probes live AI answer engines with your customers' questions, scores how often you're cited, and runs an 18-point technical audit with copy-paste fixes — no signup required.
+Do I need an AEO tool if I already use SEMrush?
Often yes. SEMrush is built around keyword and backlink SEO. An AEO-first tool measures live AI citations and audits the specific technical causes — crawler access, extractability, entity trust — that SEO suites don't focus on.
+How do AEO tools measure visibility?
They ask live AI engines real questions and record whether your domain is cited, your brand is mentioned, or you're absent, usually weighting by query intent and sampling multiple times to handle variation.
