Key takeaways
- MentionFlow undercuts Promptwatch on price at every tier ($89/$199/$499 vs $99/$249/$579) for functionally identical prompt and project limits, so on paper it looks like the better deal.
- Promptwatch is the more proven platform: live since April 2025, 1,840+ customers including Duolingo and Yelp, and a 4.5/5 rating across 17 G2 reviews. MentionFlow has been collecting data only since July 2026, has 25 brands total on the platform, and no reviews yet on Capterra.
- MentionFlow's crawler analytics go a step further with a crawl-to-citation join, matching which crawled pages actually get cited versus crawled and ignored, and it supports more CDN log sources (Cloudflare, Vercel, Fastly, Akamai, AWS CloudFront, Netlify, GTM) plus more CMS targets (adds Sanity, Contentful, Strapi, Shopify).
- Both platforms cap live model tracking at 4 engines per plan, though MentionFlow markets 10 total (with Claude and Grok on a weekly, not daily, refresh) versus Promptwatch's steadier daily coverage of its core model set.
- MentionFlow's agency angle is built around unlimited "pitch projects" for sales prospecting; Promptwatch's agency plans focus on unlimited managed client projects with white-labeling and 10 seats.
- If you want a platform with a longer track record, deeper enterprise usage, and an agentic content pipeline that publishes without much hand-holding, Promptwatch is the safer pick. If you want the newest feature set at a lower price and don't mind a platform still building its review history, MentionFlow is worth a serious look.
Overview
Promptwatch is an AI search visibility and GEO platform that tracks brand mentions across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews/AI Mode, then does something most trackers don't: it acts on what it finds. Content Agents write and publish AEO articles straight into your CMS, Unified Actions turns your visibility data into a prioritized to-do list, and Agent Chat lets you interrogate your own data conversationally. It launched in April 2025, passed EUR 2M ARR by May 2026, and now counts 1,840+ brands including Duolingo, Yelp, and Typeform as customers.
MentionFlow is a newer entrant chasing the same problem from a slightly different angle: every mention, ranking, and citation across 10 AI engines, with a "receipt" (the literal saved answer text) behind every metric. Its pitch leans on transparency, you can read the exact AI response behind any visibility number, and on crawler analytics, where it claims a crawl-to-citation join that tells you not just whether a bot visited a page but whether that visit led to an actual citation. It's the younger platform by a wide margin: live data collection only started in July 2026.

Pricing
Comparing tier-for-tier, MentionFlow is consistently $10 to $80 cheaper per month for the same prompt and project limits.
| Plan tier | Promptwatch | MentionFlow |
|---|---|---|
| Entry | Essential $99/mo (1 site, 50 prompts, 5 articles) | Starter $89/mo (1 project, 50 prompts, 5 articles, 500 agent credits) |
| Growth | Professional $249/mo (2 sites, 150 prompts, 15 articles) | Growth $199/mo (2 projects, 150 prompts, 15 articles, AI Shopping, Looker) |
| Scale | Business $579/mo (5 sites, 350 prompts, 30 articles) | Advanced $499/mo (5 projects, 350 prompts, 30 articles, chat+email support) |
| Agencies | Kick-off $199/mo, Growth $399/mo, Scale $799/mo (unlimited projects/prompts, 10 seats) | Agency track from $199/mo (unlimited client projects, per third-party listing) |
| Free tier | No, but 7-day trial | No, but 7 days for $1 |
The tier structure is close to a mirror image of each other, right down to the 1/2/5 site-or-project counts and 50/150/350 prompt allowances. That's either a coincidence or MentionFlow benchmarked directly against Promptwatch when building its pricing page. Either way, if price per prompt is your only variable, MentionFlow wins outright.
Head-to-head deep dive
Model coverage and tracking frequency
Promptwatch tracks ChatGPT, Claude, Gemini, and Perplexity as its core set, plus Google AI Overviews and AI Mode, with daily refresh across the board according to G2-reported integration data. MentionFlow advertises a longer list, 10 engines including Copilot, Grok, DeepSeek, and Mistral, but only 4 run concurrently per plan and you have to actively swap models in and out. Worse, Claude and Grok on MentionFlow only refresh weekly (every Monday), which is a real gap if a competitor gets cited by Claude on a Tuesday and you don't see it for six days.
Verdict: Promptwatch's narrower but daily-refreshed core coverage beats MentionFlow's wider-but-thinner spread, especially for anyone trying to catch fast-moving citation changes.
AI crawler analytics
Both platforms let you see which AI bots (GPTBot, ClaudeBot, PerplexityBot, and dozens more) are hitting your site, via Cloudflare, Vercel, Fastly, Akamai, AWS CloudFront, or Netlify logs. MentionFlow's specific claim to fame here is the crawl-to-citation join: it doesn't just tell you a bot visited a page, it tells you whether that visit later turned into an actual citation, versus a crawl that went nowhere. That's a genuinely useful distinction that plain crawler logs can't give you on their own.
Promptwatch's Agent Analytics covers similar ground, showing crawl timing, pages read, and errors encountered, with a citation rate per page baked into its reporting. Functionally the two are close, but MentionFlow's explicit framing of
