Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 146 of the 157 other AI search visibility tools we grade
Known Agents shows which AI crawlers, scrapers and agents visit a website, what pages they read and whether they break robots.txt rules, and it counts the human visits that arrive from ChatGPT, Claude, Gemini and other AI chats. It also serves a robots.txt that updates as new bots appear, and an API that identifies and verifies agents. It was called Dark Visitors until it took its current name.
To get you started, here are 9 things to know about Known Agents, taken from its own pages and our grades.
Data comes from your server, CDN or WordPress rather than a pasted script, so there's a bit of plumbing before anything shows up.
- 1
Best for seeing which AI bots visit your site
Known Agents, once called Dark Visitors, shows which AI crawlers and agents hit your site, what they read and whether they ignore robots.txt, and counts the people AI chats send you.

Paid plans start at $25 a month
As its pricing page puts it: $25 per month for 1M events, billed yearly ($29 billed monthly).

There is a free plan
1 project and 100,000 events a month with the basic features; the event limit is a hard cap. No credit card needed.

- 6
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.
- 7
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.

The report card
Best for seeing which AI bots visit your site
Known Agents, once called Dark Visitors, shows which AI crawlers and agents hit your site, what they read and whether they ignore robots.txt, and counts the people AI chats send you. The free plan covers 1 project and 100,000 events a month. But it doesn't check what AI answers say about you, every API call counts as an event, the free cap is hard, and it needs a server, CDN or WordPress hookup to collect anything.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | Startup is $25 a month billed yearly, or $29 monthly, for 3 projects and 1 million events. That's inside the cheaper quarter of this category, which starts at $29, and well under Siteline's $49. |
| Free plan and trial | B | Free with no card and no time limit: 1 project and 100,000 events a month, which the vendor says covers most websites. It's a hard cap, though, and the premium features are paid. |
| Features | C | Bot and agent analytics, AI chat referrals, a robots.txt that updates itself and an API to verify agents. It does that job fully, but it's a smaller one: it doesn't check what AI engines say about your brand. |
| Ease of use | C | No rating on record. Data comes from your server, CDN or WordPress rather than a pasted script, so there's a bit of plumbing before anything shows up. |
| Platforms and integrations | B | Web only, with no desktop or phone app. It hooks into WordPress, Cloudflare, Fastly, Akamai, AWS, Google Cloud, Vercel and Node.js, and has an agent identification API. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Known Agents is for
- Fits if you publish online and want to choose which AI crawlers can read your site
- Works for developers who need to verify AI agents in their own code through an API
Who it is not for
- Skip it if you want to know what ChatGPT says about your brand, as it doesn't check answers
- Tight if your site is busy: every API call and batch item counts, so budget about twice your human visits
- Not for you if you can't touch your server, CDN or WordPress setup, as there's no pasted script
- Watch out: the free plan stops at 100,000 events a month, with 1 project and only the basic features
- Watch out: custom features, a custom API and live support are on Enterprise, arranged through a demo
Good to know
Good for
- Publishers deciding which AI crawlers to let in or block
- Sites that want to measure visits sent by AI chat apps
- Developers who need to verify AI agents in their own code
Worth knowing
- It measures bot visits and AI referrals to your site; it does not check what AI engines say about your brand in their answers.
- Events include every API call and each item in a batch; the vendor suggests budgeting about twice your monthly human visits.
- The free plan stops at its monthly event limit; paid plans get an email suggesting an upgrade when they run over.
- It needs a server, CDN or WordPress integration to collect data, rather than a script pasted into the page.

- Agent Identification API

Keep it
Nothing Known Agents does is plain enough to make in a weekend. The 3 things listed below take a company.
It is one of the better ones too: its GPA of 2.6 is higher than 146 of the 157 other AI search visibility tools we grade. It costs $300 a year.
What you could not
- A tracking script and a database that counts every visit.
- The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept.
- It plugs into other products, WordPress, Cloudflare and Fastly among them, and has an API.
What this rests on. Known Agents’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
