Prefer (site) is an AEO execution tool that shows how ChatGPT, Claude, Gemini and Perplexity describe a brand, flags where it's missing, and uses autonomous agents to act on the gaps rather than just report them. It's freemium with a free trial and free audit, with paid plans starting at $24/mo (Starter, or $21/mo billed annually), rising to $129/mo (Growth) and $399/mo (Scale), plus custom Enterprise pricing. If that's more than you need right now, here are four cheaper or free-tier options, cheapest first.
Comparison
| Product | Free tier | Starts at | Best for |
|---|---|---|---|
| EzSeoAeo | Yes | $4.99/mo | One-off or occasional AEO/SEO copy generation |
| AEO Checker | Yes | $8/mo | On-demand and recurring AI visibility reports |
| Appsrow AEO Analyzer | Yes | Not stated | A free first audit before committing to a paid tool |
| Videcode AEO | Yes | $49/mo | Teams needing a high volume of AI-credit-based audits |
EzSeoAeo
EzSeoAeo (site) takes a website URL and returns copy-ready SEO and AEO headers. It suits solo site owners or small teams who want quick, pasteable output rather than a dashboard or agent system. The free version gives one SEO/AEO header generation per browser with no login; the paid subscription, starting at $4.99/mo, unlocks unlimited generates, a history library, batch processing of up to 5 URLs, and exports. The limitation: it generates copy and headers, not the broader monitoring or action layer that Prefer provides across AI models.
AEO Checker
AEO Checker (site) is a reporting tool built around a simple premise: track how AI models answer questions about a brand. It fits people who want recurring, on-demand reports without a full execution platform. The free tier gives one preview report across 2 AI models; paid plans start at $8/mo (Reports, unlimited on-demand reports), rising to $22.50/mo (Marketer) and $49.40/mo (Pro) for daily monitoring. Its limitation is that it's focused on reporting and checking, not the autonomous action Prefer offers.
Appsrow AEO Analyzer
Appsrow AEO Analyzer (site) offers a free AI website audit covering 8 key AEO factors, aimed at anyone wanting a quick first look at how their site reads to AI search before spending money. No paid-tier pricing is stated, so it's hard to compare direct cost against the others here. It's best treated as a free starting point or second opinion rather than a long-term replacement for a monitoring or execution tool, since its scope beyond the audit isn't detailed.
Videcode AEO
Videcode AEO (site) audits and optimizes a brand for AI search and LLM citations, built around a credit system. It suits teams that expect to run a lot of audits or checks monthly and want predictable capacity. The free option is a 7-day trial with no card required; the paid plan starts at $49/mo for 500 AI credits monthly with rollover (capped). At $49/mo it's actually more expensive than Prefer's own Starter tier at $24/mo (or $21/mo annual), so it's only "cheaper" in the sense of being below Prefer's higher Growth and Scale tiers.
How to choose
If budget is the main constraint and you just need generated AEO copy, EzSeoAeo at $4.99/mo is the cheapest paid option. If you want recurring visibility reports across AI models without execution features, AEO Checker's $8/mo tier is the next step up. Appsrow is worth trying first since its audit is free, even though its paid pricing isn't public. If you need credit-based volume and don't mind paying more than Prefer's own entry tier, Videcode fits. If none of these go far enough and you want action taken automatically across ChatGPT, Claude, Gemini and Perplexity, Prefer's $24/mo (or $21/mo annual) Starter plan is the closest match to that need.
