If you ask ChatGPT or Perplexity to recommend a project management app, a CRM, or a database, it gives you an answer — and that answer either includes your product or it doesn't. That's a new kind of visibility, separate from your Google ranking, and it's becoming known as GEO (Generative Engine Optimization) or AEO (Answer Engine Optimization). A handful of tools now exist purely to measure it: they run hundreds of real questions through AI assistants, track how often your brand shows up, and tell you what to fix. Below are 8 of them, all real products you can sign up for today, ranked from cheapest way to get a first read to the most built-out enterprise option.
The short version
If you just want a free gut-check, start with Bluerails Discovery or Sited — both give you a real report without a credit card. If you want ongoing tracking on a budget, LLMrefs is the cheapest recurring option at a flat $79/month. If you're a local business, findloc.ai is the only one built specifically for city-level searches like "best plumber in Austin." And if you're a funded marketing team that also wants AI to write the content that fixes the gaps, look at Gauge, Rankfender or SnowSEO.
1. Bluerails Discovery — best free first check
Bluerails Discovery is a free scanner: enter your domain and it runs roughly 400 real questions through ChatGPT, Claude, Gemini and Perplexity to see how often you come up, then hands you a report with a confidence interval instead of a vague score. No signup, no card.
Price: one free report per domain; paid tracking plans exist but aren't publicly priced.
Good for: anyone who wants a credible first read before committing budget to the category.
Watch out for: the free report is a one-off snapshot, not continuous monitoring, and there's no public pricing or team information beyond that.
2. Sited — best one-time paid audit
Sited takes a similar approach but sells a single audit for $50 (an early-access price that may rise) instead of a subscription. It checks 5 major AI platforms and also flags technical GEO issues — schema markup, robots.txt, Core Web Vitals — that make it harder for AI crawlers to understand your site in the first place.
Price: $50 one-time; free infographic-style summary with no account needed.
Good for: a founder who wants one solid report without signing up for another monthly tool.
Watch out for: it's a snapshot, not a tracker — pair it with a monitoring tool if you need to see trends over time.
3. LLMrefs — cheapest ongoing tracking
LLMrefs tracks up to 500 prompts across 11+ AI search engines (ChatGPT, Gemini, Perplexity, Claude, Copilot, Meta AI and more) for a flat $79/month with unlimited team members and projects — no per-seat pricing to worry about. Prompts are generated from real conversation patterns rather than guessed keywords, and it supports geo-targeting across 50+ countries and 20+ languages.
Price: $79/month flat, 7-day free trial.
Good for: a small team that wants continuous tracking without enterprise pricing.
Watch out for: the category is under two years old, so there's limited independent verification of how accurately any of these tools capture what AI models actually say — LLMrefs included.
4. Monroya — best for buyer-journey scoring
Monroya checks how ChatGPT, Claude, Gemini and Perplexity describe your company across different stages of the buyer journey (not just "does it mention us" but "does it describe us accurately"), and scores competitive gaps. It also drafts fact-checked content suggestions to close those gaps rather than leaving you with a report and no next step.
Price: Starter $79/month, Growth $199/month, Intelligence $299/month; 7-day free trial.
Good for: marketing teams that want the tracking and the fix-it content in one subscription.
Watch out for: pricing is built for an established marketing budget, not a bootstrapped side project.
5. findloc.ai — best for local businesses
findloc.ai is the odd one out here in a good way: instead of tracking brand mentions in general, it's a public database that checks weekly which local businesses AI assistants recommend for city-specific searches like "best plumber in Austin." There's a free tier to see where you stand, and a Signal Boost package ($499 one-time) that comes with a money-back guarantee if you're not cited by 3+ AI engines afterward.
Price: free to view + claim one listing; Signal Boost $499 one-time (guaranteed), Signal Boost Pro $1,299 one-time, or Pro at $49/month for DIY tracking.
Good for: local service businesses (plumbers, dentists, contractors) rather than SaaS or e-commerce brands.
Watch out for: $1,299 is a real investment for a small local business, and AI answers can shift over time even after you're cited.
6. Rankfender — best combined Google + AI tracking
Rankfender watches your classic Google ranking alongside your visibility across 7 AI engines (ChatGPT, Gemini, Claude, DeepSeek, Grok, Llama and more) in one dashboard, then auto-writes and publishes SEO articles through an 8-step pipeline to close whatever gaps it finds.
Price: Essential $89/month (promo $44), Professional $199/month (promo $99), Business $499/month (promo $249); 7-day free trial.
Good for: teams that want Google SEO and AI visibility tracked together instead of in separate tools.
Watch out for: promotional pricing is temporary — budget for the full $89-499/month range after the first few months, and growth numbers in its marketing are self-reported.
7. SnowSEO — best for high content volume
SnowSEO pairs AI-visibility tracking (ChatGPT, Perplexity) with SEO article generation at real scale — plans range from 30 articles/month up to 1,000/month with automatic publishing to your CMS.
Price: Starter $39/month, Pro $94/month, Scale tiers $199-$999/month; 2 months free annually.
Good for: content-heavy teams that need volume more than they need deep AI-visibility analytics.
Watch out for: the AI-visibility tracking itself is less specialized than dedicated tools like Monroya or LLMrefs, and the higher tiers overlap heavily with Rankfender's positioning.
8. Gauge — best for established marketing teams
Gauge is the most expensive tool here, tracking 600 prompts daily across major AI models plus generating 18 content pieces per month, and it's already used by marketing teams at Supabase, PostHog and Mux.
Price: Growth $599/month; Enterprise on request.
Good for: a funded company with a real marketing budget that wants daily-refreshed data and content production bundled in.
Watch out for: $599/month is out of reach for a solo founder, and like every tool on this list, AI answers are inherently noisy — treat any single measurement as a trend indicator, not gospel.
| Tool | Best for | Starting price | Free option |
|---|---|---|---|
| Bluerails Discovery | Free first check | Paid plans unpriced | Yes, full report |
| Sited | One-time paid audit | $50 one-time | Free infographic |
| LLMrefs | Cheapest ongoing tracking | $79/mo flat | 7-day trial |
| Monroya | Buyer-journey scoring + content | $79/mo | 7-day trial |
| findloc.ai | Local businesses | Free / $49/mo | Yes, view + 1 listing |
| Rankfender | Google + AI combined | $89/mo (promo $44) | 7-day trial |
| SnowSEO | High content volume | $39/mo | No |
| Gauge | Established marketing teams | $599/mo | No |
None of these categories are mature yet — the whole space is under two years old, the underlying AI answers are non-deterministic by nature, and every vendor's growth numbers in this list are self-reported. That doesn't make the tracking useless, but treat any single tool's score as a directional signal, not an exact metric. If you're just getting started, run one of the free options (Bluerails Discovery or Sited's free infographic) before paying for anything — it costs nothing and tells you whether this is even a gap worth closing for your brand.
