Write down the brand you already have
Tin inspects your website, and your repository if you want, and proposes two documents: a concise brand guide for future marketing, and a record of the product design you have today. You review both before any workflow uses them.

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.
- 01Reads your public site, and the selected GitHub repository when you include it.
- 02Records colors, type, tone and the components you already use, keeping any choices you note.
- 03Proposes brand/BRAND.md and DESIGN.md together for one review.
- 04After approval, later work such as diagrams uses them as active guidance.
Capture our brand and design in Tin from the website and the repo, and let me review it.
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 knows where the design tokens and components live, so the guide describes what the product really uses.
All workflows →Runs well with.Workflows that feed this one, or follow it.
Questions.
Will it redesign my brand?
No. By default it records the identity you have. A develop option allows modest supporting guidance for new marketing assets.
Does it change my repository?
No. It reads the repository only. The documents live in project Files.
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.
