One MDX source serves AI agents and human readers from the same URL. And when your product changes, Thally drafts the docs PR.
Built for the AI tools your readers already use
Your team maintains one set of pages. Everyone who reads them, person or agent, gets the version they can actually use.

Write once.Thally creates every format.
How do I rotate an access token?
Send a POST request to /v1/tokens/rotate with your current token. The previous token stays valid for 60 seconds so in-flight requests keep working.
Answers with receipts.Grounded chat cites your docs.
A readiness score you can gate CI on
Score how well each page serves human and AI readers, and fail builds that ship gaps.
Search without leaving the docs
Hybrid keyword and semantic search with grounded answers, all from one index.
Review every docs task in one queue
Updates from merged changes, drift sweeps, and @thally mentions, approved before merge.
Give AI tools a direct path
llms.txt, Markdown projections, and a remote MCP server on every deployed site.
Thally turns shipped code into shipped docs. Every change lands exactly where it belongs.
Bring your existing docs to Thally.
Use Thally Cloud to migrate a public docs site, or run the CLI against a GitHub repository. Either path creates editable MDX and a Thally project you control.

Deploys to
- Vercel
- Netlify
- Cloudflare
- Docker
- Static export
Your migrated docs become an editable Thally project. Self-host the MIT-licensed engine, or let Thally Cloud build and publish it for you.
Thally watches the repos you choose and drafts only the updates the evidence supports.
Set it up once. It runs on every merge.
Install the read-only GitHub App and choose the product repos Thally should watch. You choose exactly what Thally can see.
Understand the change before the update.
Track evaluates merged changes, gathers evidence, and finds the documentation each change affects.
Evidence-backed drafts, ready to review.
Thally opens a pull request on your docs repo only when the evidence says an update is needed.
You approve what ships. Every time.
Your team reviews, edits, and merges. A no-change result is valid. Thally never pushes to main.
Pay for the service. Keep the source. Thally Cloud never takes ownership of your content, repository, engine, or domain.
Your content stays in your repository
Your documentation remains as source files in your repository. There is nothing to export because we never hold the source.
The publishing engine is open source
The engine behind Thally Cloud is available on GitHub under the MIT license. You can host it yourself at any time.
Self-hosting stays available
Clone the repository and deploy the open-source engine wherever Next.js runs. Managed hosting is a service, not a content lock-in.
Your domain stays under your control
Thally never takes ownership of your domain. Use it wherever you deploy the site.
Cancellation leaves you with the source
Your repository and the MIT-licensed engine remain yours. If Cloud hosting ends, you can deploy the site elsewhere.
Humans approve important communication
Thally prepares reviewable work. Your team keeps judgment and publishing authority.
Understand before generating
Thally finds what changed, gathers evidence, and maps the affected knowledge before drafting new words.
A no-change result is valid
Thally reports when no documentation update is needed instead of inventing one.
