Capture your writing style once, reuse it in every draft
Your coding agent selects writing samples with your permission, or you add them yourself. Tin saves an editable voice guide that later content workflows load.

What the workflow does.The same steps, every run.
A Tin workflow is a repeatable job: declared inputs, a bounded run and a defined output.
- 01Asks once, in a short conversation, which samples it may use.
- 02Reads the samples at the path you give it.
- 03Writes a voice guide you can edit like any other project file.
- 04Later drafts load the guide, so the voice stays consistent.

What every workflowcomes with.
Battle tested on real products
These are the workflows we run for real companies. Claw Messenger went from about $45 to $2,105 in monthly revenue in 124 days on them. Each one has declared inputs, bounded execution and tests, and anything public waits for your review.
See the case study →Open source: read it, fork it, self-host it
Apache 2.0. Every workflow is a folder in the repository: the steps it runs, the data it reads and what it is allowed to do. Change it, or run the whole system on your own machine.
Open the repo →Runs on the agent that already knows your product
Your agent already knows where your writing lives in the repository, so picking good samples takes a minute.

Questions.
Which samples work best?
Finished writing in the voice you want: blog posts, essays, longer notes. A handful of strong samples beats a large pile.
Can I change the guide later?
Yes. It is a plain file. Edit it and future drafts follow the new version.
Is Tin really open source?
Yes. Tin is licensed under Apache 2.0 and the source is at github.com/tin-computer/tin. You can read every workflow, change it, and self-host the whole system.
Which coding agents can run Tin workflows?
Any agent that speaks MCP, including Claude Code, Codex and Cursor. There is also an API, and the same projects run in the browser at app.tin.computer.
Why run marketing from a coding agent?
Because it already knows your product. It has the repository open, so it fills workflow inputs accurately, reviews output against what the product really does, and can act on the results in the same session.
Add Tin to your coding agent.It takes one command.
