Key takeaways
- Mentionable is cheaper to start (EUR79/mo vs $95/mo) and includes all 7-8 AI engines on every plan with no per-engine gating. Promptwatch caps active model tracking at 4 concurrently even on paid tiers, despite listing 8 supported engines.
- Promptwatch actually writes and publishes content. Its Content Agent generates AEO articles and pushes them live to Webflow, Framer, or WordPress. Mentionable drafts copy but has no CMS integration, so a human still has to publish the fix.
- Mentionable has unique discovery features Promptwatch lacks: fan-out query tracking, a "missed citations" report (content used by an LLM without your brand named), and a Quantified Backlinks module pricing out placements on domains models cite in your niche.
- Promptwatch has crawler log analysis, geographic (state/city) tracking, Shopping Insights, and Ads Radar, all things Mentionable simply doesn't build for.
- Promptwatch is backed by a funded team (EUR6M seed, 1,840+ customers, 4.7/5 on G2 from 17 reviews); Mentionable is built and run solo by one French developer with no outside funding, which matters if you're betting an agency offering on the roadmap staying alive.
- If your team is comfortable writing its own pages and just wants broad, ungated engine coverage cheaply, Mentionable wins on price-to-coverage. If you want monitoring and content production in one subscription, Promptwatch wins.
Overview
Promptwatch is an AI search visibility platform that tracks how brands show up across ChatGPT, Gemini, Claude, Perplexity, Grok, Meta Llama, DeepSeek, and Mistral, and then does something most trackers don't: it acts on what it finds. Its Content Agent plans, writes, and publishes GEO-optimized articles straight into your CMS, backed by crawler log analysis that shows exactly how AI bots are reading your site. It's used by 1,840+ brands including Duolingo, Yelp, and Amazon, and carries a 4.7/5 on G2.
Mentionable is a smaller, faster-moving GEO tracker built by a solo developer in France, launched in January 2026. Its pitch is straightforward: track all major AI engines daily without gating features behind per-model add-ons, and surface the specific questions where competitors get cited instead of you. It skips the content-publishing layer entirely and focuses on measurement, competitor benchmarking, and lead-magnet tools that agencies can use for prospecting.

Head-to-head deep dive
Engine coverage
This is the single biggest structural difference between the two. Mentionable's whole pitch is that every plan, even the EUR79/mo Growth tier, gets all 7-8 engines with zero gating. Promptwatch technically supports 8 engines (OpenAI, Perplexity, Google AI Overviews and AI Mode, Claude, Gemini, Meta Llama, DeepSeek, Grok) but its own pricing page caps active concurrent tracking at 4 models per project regardless of tier. If comprehensive multi-model coverage on a tight budget is the priority, Mentionable wins this round outright.
Verdict: Mentionable, on paper. Promptwatch's model cap is the one pricing decision that's easy to miss and genuinely worth double-checking before you buy.
Content and remediation
Here's where the story flips. Promptwatch doesn't stop at telling you where you're invisible, it generates AEO articles (5 to 30 per month depending on tier) and its Content Agent publishes them directly into Webflow, Framer, or WordPress on a schedule you control. Mentionable's own comparison materials are candid about this gap: it finds where you're missing but doesn't write the fix into a CMS. You get drafted copy, then you're on your own to publish it.
Verdict: Promptwatch, clearly, if you want a tool that closes the loop rather than just generating a to-do list.
Discovery and diagnostic features
Mentionable has a few genuinely distinctive tools Promptwatch doesn't ship: fan-out query tracking (showing the sub-queries an LLM runs before answering), a missed-citations report (content that's being used by an AI answer without your brand being named), and a Quantified Backlinks module that prices out placements on domains models cite in your niche. Promptwatch counters with crawler log analysis and agent analytics, which show exactly when ChatGPTBot, ClaudeBot, and PerplexityBot visit your site, what they read, and whether they hit errors, something Mentionable has no equivalent for.
| Diagnostic feature | Promptwatch | Mentionable |
|---|---|---|
| AI crawler logs (bot visits, errors) | Yes | No |
| Fan-out query mapping | No | Yes |
| Missed citations detection | Via content gap analysis | Dedicated report |
| Prompt volume + difficulty scoring | Yes | No |
| Shopping/Ads tracking in AI answers | Yes (Shopping Insights, Ads Radar) | No |
| Quantified backlink pricing | No | Yes |
Verdict: split. Promptwatch goes deeper on technical/crawler-side diagnostics; Mentionable goes deeper on query-level and citation-gap discovery.
Ease of use and onboarding
Independent reviewer Brandon Leuangpaseuth found Promptwatch's demo and onboarding frictionless compared to rivals like Profound, but flagged that the dashboard, spanning visibility, crawler logs, mentions, and content generation, can feel like a lot for a first-time user. Mentionable's dashboard is narrower by design: mention rate, citation rate, competitor table, and a list of missing prompts. Fewer tabs, less to learn, but also less depth once you outgrow the basics.
Verdict: Mentionable for a faster ramp-up, Promptwatch for teams that will eventually want the extra tabs anyway.
Agency and white-label features
Mentionable's Agency plan (EUR299/mo) is packaged specifically for agencies: white-label reports with custom logo, colors, and domain, bulk audits across up to 500 sites, unlimited client projects, and six free lead-magnet tools including a visibility checker and llms.txt generator for prospecting new clients. Promptwatch has its own dedicated Agencies tier structure (Kick-off, Growth, Scale) with unlimited projects and prompts and 10 seats, plus enterprise-level white-labeling on custom plans, but the prospecting-tool angle is less built out than Mentionable's.
Verdict: Mentionable edges ahead for agencies focused on client acquisition tooling; Promptwatch edges ahead for agencies managing larger enterprise accounts that need the full monitoring-plus-content stack.
Company stability and track record
This one matters more than most comparison pages admit. Promptwatch has 1,840+ customers, a EUR6M seed round led by Seed + Speed Ventures, and a 4.7/5 rating across 17 G2 reviews. Mentionable is built by a single French developer, Alexandre Rastello, with no outside funding, roughly 50 brand customers, and no G2 presence yet as of this writing. The founder is transparent about MRR and roadmap on LinkedIn, which is refreshing, but it's still a one-person bet.
Verdict: Promptwatch, if platform longevity and support responsiveness under scale matter to your decision. Mentionable is fine for teams comfortable with an early-stage, indie tool.
Pricing comparison
| Plan tier | Promptwatch | Mentionable |
|---|---|---|
| Entry | Essential: $95/mo (1 project, 50 prompts, 4 models, 6,000 responses/mo) | Growth: EUR79/mo (1 project, up to 115 prompts, 1,500 scan credits) |
| Mid | Professional: $245/mo (2 projects, 150 prompts, 18,000 responses, 5 AEO articles) | Pro: EUR149/mo (3 projects, up to 231 prompts, 3,000 credits, MCP access) |
| Top | Business: $579/mo (5 projects, 350 prompts, 42,000 responses, 10 AEO articles, Shopping Insights, Ads Radar) | Agency: EUR299/mo (unlimited client projects, up to 385 prompts, 5,000 credits, white-label) |
| Overage | Not stated publicly | EUR0.02 per scan credit, user-set spend cap |
| Free tier | Free trial only, no permanent free plan | Free trial only, no permanent free plan |
One independent review (Citeme) flagged that Promptwatch's genuinely useful tier starts around $245/mo, not the $95 entry price, because the entry tier's 4-model cap and lack of AEO articles limit what you can actually do with it. Mentionable's Salesdorado review rated its quality-price ratio at 4.6/5, specifically citing the no-per-engine-upcharge structure as the standout value, while rating its overall maturity lower at 3.7/5.
Pros and cons
Promptwatch pros
- Generates and publishes AEO content directly into your CMS, closing the loop from insight to action
- Crawler log analysis shows exactly how AI bots crawl your site, a feature Mentionable doesn't have at all
- Funded company with 1,840+ customers and a 4.7/5 G2 rating
- MCP and API access on every tier, including the entry plan
- Shopping Insights and Ads Radar track a part of AI search most competitors ignore
Promptwatch cons
- Model tracking capped at 4 concurrent engines even on paid tiers, despite listing 8 as supported
- The genuinely useful tier starts around $245/mo, not the $95 entry price
- Dashboard complexity can overwhelm first-time users
Mentionable pros
- All 7-8 AI engines included on every plan, no per-engine upcharge
- Cheaper entry point at EUR79/mo
- Fan-out query tracking and missed-citations reports are genuinely useful discovery tools
- Agency plan bundles white-label reporting and free prospecting tools
Mentionable cons
- No CMS publishing, drafts content but doesn't ship it for you
- Single-developer product with no outside funding and no G2 track record yet
- Scan-credit model means lower budgets get sparser data refreshes
- Trial length is inconsistently reported across the company's own materials (4 vs 7 days)
Who should pick which tool
Pick Promptwatch if you're an SEO team or agency that's already producing content and wants one subscription that monitors AI visibility and then writes and publishes the fix, especially if you also care about crawler-level technical data, Shopping/Ads visibility in AI answers, or geographic tracking down to the state and city level. It's also the safer bet if platform stability and vendor track record matter for a client-facing offering.
Pick Mentionable if you're a solo founder, small SaaS team, or lean agency that wants broad engine coverage without paying extra per model, doesn't need in-product content publishing because your team writes and ships pages anyway, and wants agency-prospecting tools like a free visibility checker to pull in new clients. Just go in aware you're betting on a single-developer product at this stage.
If what you actually need is broader AI search visibility strategy rather than just a tracker, either tool works as raw data; you'll still want a content and technical execution plan around it. For teams weighing several AI visibility platforms at once, the GEO software directory at bestgeosoftware.com is a reasonable place to see how these two stack up against the wider field.
Final verdict
Mentionable wins on price-to-engine-coverage and gives you sharper discovery tools like fan-out tracking and missed citations. Promptwatch wins on doing something about what it finds, with content generation, CMS publishing, and crawler-level diagnostics that Mentionable simply doesn't build for. If your bottleneck is finding gaps, start with Mentionable's cheaper plan. If your bottleneck is turning gaps into published, cited content, Promptwatch is worth the higher price.
