Key takeaways
- Mentionable includes all 8 AI engines (ChatGPT, Claude, Perplexity, Gemini, Copilot, Google AI Mode, Google AI Overviews, plus one more) on every plan at no extra cost. AI Peekaboo treats Claude and Copilot as paid add-ons on top of its 5 core models.
- AI Peekaboo's entry price is technically lower ($29-50/mo) but its pricing is a usage slider based on brands, prompts, models, and frequency, so real costs climb fast once you want daily tracking and white-label reports.
- For agencies, Mentionable is the clear pick: unlimited client projects on its €299/mo Agency plan versus AI Peekaboo's hard cap of 5 brands even at $200/mo.
- AI Peekaboo has more visible third-party proof (9 reviews on G2, 4.8/5) even though the sample is small. Mentionable has no G2 page yet but a solid independent review from Salesdorado (4.2/5).
- Mentionable goes a step further than tracking by drafting pages aimed at closing citation gaps it finds; AI Peekaboo stops at tracking, benchmarking, and a to-do list of actions you execute yourself.
- Both tools are run by small teams (Mentionable by a solo developer, AI Peekaboo out of a dual Lisbon/Minnesota HQ), so neither has the depth of a large enterprise platform. If you need crawler logs, AI traffic attribution, and CMS publishing baked in, that's a different category of tool entirely.
Overview
Mentionable is a French-built GEO tracker that scans 8 AI engines daily, without gating any engine behind a paid add-on. It generates prompts automatically from your URL, shows you which sources AI engines cite instead of you, and, on higher plans, drafts the actual page you're missing and then tracks whether that page gets cited. It launched in January 2026 and is run by one developer who ships fast based on user feedback, which is either exciting or a little risky depending on how you feel about single-person software.
AI Peekaboo is a visibility tracker aimed squarely at SaaS companies, with a slider-based pricing model: you pick your brand count, prompt count, model selection, and check frequency, and the price adjusts accordingly. It covers 5 core engines by default (ChatGPT, Gemini, Perplexity, Google AI Overviews, Google AI Mode) with Claude and Copilot as paid extras. It's newer to the MCP game but has caught up with a Claude Desktop/Cursor integration, and it ships Looker Studio and Google Search Console connections already, with GA4 and WordPress listed as coming soon.
Side-by-side comparison
| Feature | Mentionable | AI Peekaboo |
|---|---|---|
| Starting price | €79/mo (Growth) | $29-50/mo (Starter, usage-based) |
| Pricing model | Fixed tiers + credit overage | Continuous slider (brands x prompts x models x frequency) |
| Engines included by default | 8, all included | 5, with Claude and Copilot as paid add-ons |
| Tracking frequency | Daily | Every 2 days (Starter) or daily (Peek/Grow) |
| Free trial | 4 days, no card | 14 days, card sometimes required |
| Multi-brand agency plan | Unlimited client projects at €299/mo | Capped at 5 brands even at $200/mo |
| White-label reports | Yes, on Agency plan | Yes, from $100/mo tier up, but full white-label domain still "coming soon" |
| MCP integration (Claude/Cursor) | Yes, Pro and Agency plans | Yes, newly added |
| Content generation for citation gaps | Yes, credit-based AI page drafting | No, tracking and to-do list only |
| Google Search Console / Looker Studio | Not confirmed as native | Yes, both live |
| Third-party review presence | No G2 listing yet; strong independent reviews (Salesdorado 4.2/5) | G2 listing, 4.8/5 from 9 reviews |
| API access | Included via MCP on paid plans | Included from Peek ($100/mo) tier up |
Engine coverage
This is the single biggest differentiator between these two tools. Mentionable puts all 8 engines, including Claude and Microsoft Copilot, on every plan starting at €79/mo. AI Peekaboo's self-serve tiers only cover ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode; if you want Claude or Copilot data, that's an add-on cost on top of your base plan.
If your buyers are the kind of people who ask ChatGPT questions on their phone and ask Copilot the same thing at work, missing Copilot coverage is a real gap. Mentionable's flat inclusion of every major engine is the more defensible pricing decision here, and it's the reason Salesdorado's review calls it the best quality-price ratio in the category.
Verdict: Mentionable wins clearly on engine coverage. AI Peekaboo's add-on model punishes exactly the buyers who care most about full coverage.
A quick aside on AI visibility data in general
Worth noting, since both tools are chasing the same signal: which sources actually get cited shifts fast. Reddit's share of ChatGPT Search citations dropped from roughly 4% to 0.5% in a single day in August 2026, per Promptwatch's tracking of daily citation share (see Promptwatch Data's Reddit citation report). Any tool that only refreshes weekly is going to miss swings like that entirely, which is one reason daily scanning matters more than it sounds like on a feature list.
Pricing model philosophy
Mentionable uses three fixed tiers (Growth, Pro, Agency) plus metered overage at €0.02/scan if you blow through your monthly credits. AI Peekaboo uses a continuous slider: pick brands, prompts, models, and frequency, and watch the price move. AI Peekaboo's published reference points are Starter ($50/mo), Peek ($100/mo,
