Announce what shipped, in the shape each channel expects
Give Tin the entries for one release. It writes a post for each of X, LinkedIn, Reddit and Hacker News, plus a newsletter email for people who already follow the product, and mentions nothing that did not ship.

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.
- 01Takes this release's changelog entries, one change per line.
- 02Extracts what changed and who it matters to.
- 03Writes posts for X, LinkedIn, Reddit and Hacker News, and a newsletter email, in your tone and voice notes.
- 04Saves the drafts for review, with the release link as the only link.
Use Tin to draft release posts from the entries for v2.3 in our CHANGELOG.
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 read the merged pull requests behind the changelog, so every claim in the posts matches what actually shipped.
All workflows →Using something else for this?What it replaces, and what it does not.
Runs well with.Workflows that feed this one, or follow it.
Questions.
Will it post for me?
No. You copy each draft to its channel. For X, Draft for X can take a post through preview and approved publishing.
What if the changelog is vague?
The posts only cover what the entries say. Write one concrete change per line for the best result.
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.
