X posts that sound like you, because they learn from you
Tin reads up to 50 of your own public X posts, favoring recent writing, or samples you supply instead. It proposes an editable voice guide, and future X drafts use it once you approve.

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.
- 01Samples your connected X account, skipping reposts, quotes, duplicates and thin replies, or uses samples you supply.
- 02Writes a voice guide from what it finds, stating its limits when the sample is small.
- 03Waits for your review in Decisions.
- 04Saves the approved guide as an editable file that later X drafts load.

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 can add preferences you have stated before, such as words you never use, so the guide starts closer to right.
All workflows →Runs well with.Workflows that feed this one, or follow it.
Questions.
Do I need to connect X?
No. You can supply samples or a Markdown file instead. Connecting lets Tin read your own public posts.
Can I edit the guide?
Yes. It is a plain file. Edits you make shape every later draft.
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.
