Key Takeaways
- Mentions.so is the cheaper way in: $49/mo for 25 prompts, versus Promptwatch Essential at $95/mo for 50 prompts. At roughly $99 vs $95 the prompt counts are the same (50), but Promptwatch includes all models, Agent Chat and MCP/API.
- Promptwatch goes past monitoring. It has content gap analysis, a Content Agent, Content Refresh, the Action Board and publishing to WordPress, Webflow and Framer. We found none of that on Mentions.so.
- Promptwatch has IP-verified AI crawler logs and visitor analytics, so you can see whether AI bots read your pages and whether AI traffic converts. Mentions.so mentions AI traffic analytics, but with less detail.
- Mentions.so wins on seats and agency pricing: unlimited seats on every plan and a $399 Agency tier with white-label and a pitch workspace.
- Promptwatch has a free Explore plan and a 7-day trial. Mentions.so has neither that we could find.
- Promptwatch tracks the real UIs of ChatGPT, AI Overviews, AI Mode, Copilot, Gemini, Perplexity and more, plus Reddit, YouTube and LinkedIn citations. The Mentions.so demo shows a narrower, older-looking model list.
Overview
Promptwatch
Promptwatch is an end-to-end AI search visibility and GEO platform. It tracks how your brand appears in ChatGPT, Google AI Overviews, AI Mode, Gemini, Perplexity, Copilot, Claude and others, by scraping the real user interfaces rather than relying only on APIs. That matters because user-facing answers and citations often differ from API output.

The part that separates it from most trackers is what happens after the numbers. Content gap analysis shows which prompts you lose, the Content Agent writes and publishes to your CMS, and the Action Board gives you a prioritized to-do list. Published pages then get tracked through crawls, citations and AI traffic. It reports 1,840+ brands and a 4.7/5 rating on G2 (self-reported), with customers like Yelp, Duolingo and Typeform.
Mentions.so
Mentions.so is a monitoring tool for brand mentions in AI answer engines. The demo dashboard shows a visibility score, average position, sentiment, share of voice, a competitor ranking table and a live feed of individual AI responses, with filters for model, competitor, location and topic.

It is simple and cheap, which is its appeal. The downside is that the public site is thin. There is no pricing page (it returns a 404), no integrations list, and no visible content or optimization tooling. Plan details below come from a third-party review of the pricing cards, and that reviewer (Trakkr) is a competitor, so treat the numbers as probably right but not gospel.

Head-to-head deep dive
Monitoring and data quality
Both tools give you the basics: visibility, position, sentiment and share of voice against competitors. Mentions.so's "Your Mentions" feed is nice, since you click through to the exact response for each prompt. Its demo also shows an "Open Web Share of Voice" metric across analyzed sources.
Promptwatch collects from the real interfaces in each country and language, adds prompt volumes, difficulty scores and query fan-outs, and breaks citations into content and source types. It also tracks Reddit, YouTube and LinkedIn citations, which most trackers skip. The demo model labels on Mentions.so (Claude 3.5 Haiku, ChatGPT 4o-mini) look stale, which makes me doubt how closely it follows model changes.
| Area | Promptwatch | Mentions.so |
|---|---|---|
| Visibility, position, sentiment, SOV | Yes | Yes |
| Prompt volumes and difficulty | Yes | Not found |
| Query fan-outs | Yes | Not found |
| Reddit / YouTube / LinkedIn citations | Yes | Not found |
| Per-response view | Yes | Yes |
Verdict: Promptwatch, clearly. It answers why you are or aren't visible, not just whether you are.
Optimization and content
This is the widest gap. Promptwatch's Content Agent plans, writes and publishes against your visibility gaps on a schedule, with a review inbox if you want a human gate. Content Refresh gives git-diff-style updates for existing pages, and a Knowledge Base and Brand Book keep tone consistent. The Action Board's Discovery agent suggests up to five evidence-backed actions a week.
Mentions.so's tagline says "actionable insights," but we found no content generation, gap analysis or CMS integration. That may just mean it isn't documented. If you plan to act on the data yourself, it may be enough.
Verdict: Promptwatch, by a wide margin.
Technical visibility and traffic
Promptwatch logs GPTBot, ClaudeBot, PerplexityBot and other crawlers with IP verification, so spoofed bots get filtered out. You see which pages they read, which errors they hit, and the crawl-to-citation path. Visitor analytics then tie AI traffic to conversions, and Search Console and Bing data sit next to AI data per page. Weekly site audits run 21 checks.
Mentions.so's Starter plan lists AI traffic analytics, but there is little public detail on how it works.
Verdict: Promptwatch.
Integrations and automation
Promptwatch connects to Cloudflare, AWS CloudFront, Fastly, Vercel, Netlify and others for logs, publishes to three CMSs, connects Slack, Looker Studio, Google Search Console and Bing Webmaster Tools, and ships a hosted MCP server and REST API. We found no integrations list for Mentions.so.
Verdict: Promptwatch.
Teams and agencies
Here Mentions.so is competitive. Unlimited seats on every plan is a real perk if you have a big marketing team, and the $399 Agency plan (300 prompts, unlimited sites, pitch workspace, custom domain, 100% white-label) is aggressively priced. Promptwatch's Agencies plans (Kick-off $199, Growth $399, Scale $799) include unlimited projects, 10 seats, pitch projects, a white-label workspace and client portal, and more responses, but cost more at the top end.
Verdict: Mentions.so for raw price and seat count; Promptwatch for depth per client.
Ease of use
Mentions.so is the simpler product. Fewer features means a shorter learning curve. Promptwatch has more surface area, though Agent Chat (a conversational analyst over your data) softens that, and the onboarding is well regarded in third-party reviews.
Verdict: Mentions.so for simplicity, Promptwatch for what you get once you learn it.
Pricing comparison
Always confirm on promptwatch.com/pricing. Mentions.so figures come from a third-party review, with about 16% off for yearly billing.
| Plan level | Promptwatch | Mentions.so |
|---|---|---|
| Free | Explore: $0 (1 project, 10 prompts, ChatGPT only) | None found |
| Entry | Essential: $95/mo (50 prompts, 6,000 responses, all models) | Starter: $49/mo (25 prompts, 3 LLMs, 1 site) |
| Mid | Professional: $245/mo (150 prompts, 2 projects, 5 AEO articles) | Pro: $99/mo (50 prompts, 5 sites, all LLMs) |
| Upper | Business: $579/mo (350 prompts, 5 projects, Content Agent) | Business: $199/mo (100 prompts, 10 sites) |
| Agency | Kick-off $199, Growth $399, Scale $799 | Agency: $399/mo (300 prompts, unlimited sites) |
| Enterprise | Custom, SSO, dedicated success manager | Not listed |
The cost per prompt favors Mentions.so on paper. But Promptwatch pricing buys you content tools, crawler logs and the Action Board, which Mentions.so doesn't show. If you only need prompt tracking, you're paying for things you won't use.

Who should pick which
| If you are... | Pick |

| A large team that needs many seats on a small budget | Mentions.so |
| A small agency that mainly needs white-label reporting | Mentions.so (Agency) or Promptwatch Agencies |

If you're still shopping around, the GEO software directory lists more options. For context on what AI models cite, Promptwatch's software citation share report (Sep 28 to Oct 4, 2026) shows GitHub, Microsoft's docs and G2 leading, with documentation and help centers earning the largest share. That's a good reminder that tracking mentions only gets you so far; the pages AI actually reads matter.
Final verdict
Promptwatch is the better platform; Mentions.so is the cheaper one. If a mention count is all you need and every dollar counts, Mentions.so does the job at $49. If you want AI search to become a revenue channel, with crawler logs, content gap analysis, publishing and traffic attribution, Promptwatch is the one to buy.
