Fresh off the drawing board v0.1.0 ↗

A little ink.
A lot of
clarity.

A UI annotation library for hand-sketched marks on live interfaces. Built for coding agents and developers, with project skills and a typed API that work on the controls you already have.

Your agent. Your code.
The same little marks.

Install Stet, then add marks with your coding agent or write them yourself. Your UI keeps its layout, focus, and clicks.

Start with your agent.

Project skills guide annotation choices, validate plans, and provide examples for your framework. Supports Codex, Claude Code, Cursor, and OpenCode.

Start with the API.

Typed primitives and framework adapters let you attach marks directly. The browser core has zero runtime dependencies.

Sticks with you.

Marks follow resizing, wrapped text, and scrolling. Life happens. The ink keeps up.

Knows when to be still.

Motion is optional. Reduced-motion preferences are respected. A quiet kind of playful.

WORKING UI / SHARED CONTEXT

Explain the risk.
Show what changed.

Use hand-drawn annotations in documentation, product demos and implementation reviews. A coding agent can turn a request into a validated plan and framework code, then visually hand off its work. Your app keeps its controls; Stet adds the marks.

Product intent, UX critique and QE findings can point to the same interface. No accounts, comments service or collaboration platform required.
