Key features
Known Agents
- Agent Analytics
- Lists the crawlers, scrapers and AI agents visiting a site in real time, with traffic trends, pages visited, sessions, errors and robots.txt violations per agent.
- AI chat referral tracking
- Counts human visits that come from ChatGPT, Claude, Gemini, Copilot, Perplexity, DeepSeek and other AI chats, kept apart from bot traffic.
- Automatic robots.txt
- Serves a robots.txt that blocks or allows agents by category and updates itself as new bots are found; the WordPress plugin can block bots that ignore it.
- Agent Identification API
- Identifies and verifies the agent behind an incoming request from your own code, for setting access rules by verified identity.
- Server-side collection
- Data is sent from the server, CDN or backend rather than a browser script, so it still works when browser analytics are blocked.
- Agent Directory
- A public directory of thousands of agents and bots that says who runs each one, what it does and how to manage its access.
Promptwatch
- All-model monitoring
- Every tracked prompt runs across all supported models at once, comparing visibility, citations and sentiment by model on one dashboard.
- Content gap analysis and AEO articles
- Uses the sources AI cites to find missing content, then writes and refreshes articles meant to be cited more often (Professional and up).
- Crawler logs and agent analytics
- Logs AI crawler visits through Cloudflare, Vercel and other connections, with conversion tracking for AI-referred traffic.
- Local and shopping tracking
- Country-level tracking on every plan; Business adds state and city tracking, shopping insights and Ads Radar for ads in AI answers.
- Agent Chat and technical fixes
- An agent answers questions about the data and suggests technical and competitor-driven optimizations.
- MCP, API and CMS connections
- MCP and API access on every plan, Data Studio, and connections to WordPress, Webflow, Framer, Search Console, Bing Webmaster Tools and Slack.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
