AI documentation generator
Point it at the code. Get a docs site with guides and API reference.
Sites built with Chatly
Every one of these is a page type the builder makes. Open one to build it.
How it works
Connect the source
Link a repository, upload an OpenAPI or GraphQL schema, or drop in existing docs and README files. Chatly reads the code, comments and examples.
Review the docs
You get a getting started guide, how-to guides and an API reference with a page per endpoint. Edit any page, and every claim links back to the code it came from.
Publish and keep current
Publish on your docs domain. When the code or spec changes, Chatly drafts the updates as a change you approve, so docs stop drifting.
Features
The spec and 84 files read; the reference is generated from them.
What people build with it
API and platform teams
Publish a reference that matches the API on the day it ships, with samples developers can paste. Support questions about undocumented fields stop arriving.
Open-source maintainers
Turn a long README and scattered issues into a proper docs site with a quickstart and guides. New contributors find answers without opening an issue.
Internal engineering teams
Document internal services and tools from the code they live in, so the next engineer to touch them does not have to ask around first.
Everything a site needs, built in
Hosting and a custom domain
Publish to an chatly.site address, then connect your own domain. SSL is handled.
Forms that go somewhere
Submissions land in Chatly, your email, a spreadsheet or your CRM, with spam filtered.
SEO, Open Graph and schema
Pages ship as static HTML with meta tags, share images and structured data from day one.
Analytics from the first visit
Visits, sources and conversions, collected without a tag manager.
Edit by clicking, or in the chat
Rewrite a headline where it sits, or describe the change and watch it land.
Your code, exportable
Drop in custom HTML, CSS or scripts, and export the static files whenever you want.
Pay for finished work

Frequently asked questions
What can it generate documentation from?
Code repositories, OpenAPI and GraphQL schemas, code comments, README files and existing docs. The more of these you connect, the more complete the result.
Will the docs go out of date?
Connected sources are watched. When the code or spec changes, Chatly drafts the matching doc changes for someone to approve.
Does it write code samples?
Yes. Every endpoint gets request samples in several languages and an example response, based on your schema and real examples in the repo.
Can I host the docs on my own domain?
Yes. Publish on a docs subdomain you own, with your logo, colours and navigation.
Can I edit what it writes?
Yes. Every page is editable, and your edits are kept when Chatly updates the generated parts around them.
