An open-source Frase alternative, run by your coding agent
Frase helps you research a query and write a brief and draft in its editor. Tin does the research, the plan and the draft as open-source workflows, and adds answer pages built from AI visibility findings.

What Tin does not replace
Tin is not a clone. Here is where each one fits.
Frase still does this better
- An in-browser editor with SERP research side by side.
- Optimization scoring.

What every workflow here comes 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
Tin connects to Claude Code, Codex or Cursor over MCP. That agent has your repository open and knows your product, customers and voice, so it fills the inputs and reviews the output. You never brief a new tool from zero.

Each one is a folder in the repo. Open a page for its steps, inputs and output.
Questions
Can Tin write a content brief?
The content plan records each piece with its evidence, which serves as the brief for the drafting workflow.
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.
