Marky is point-and-comment review for the things Claude makes. Claude writes a plan, a spec, a page — you publish it to a link, then click any line and leave a note, Figma-style. Claude reads the comments and ships a new version on the same link, with history. No screenshots, no re-pasting "the third paragraph, the one about pricing."

Easiest: in a Claude Code session, just ask — "install the marky-im/marky plugin." Claude runs it for you (you approve the install once, or it's automatic on auto-approve), then run /reload-plugins to switch it on live — no restart.

Or do it by hand:

/plugin marketplace add marky-im/marky
/plugin install marky@marky-im
/reload-plugins

/reload-plugins activates everything live in the current session — the marky skill and the marky command on PATH, no restart. (Requires bun.)

How it works

Once installed, just tell Claude to "marky it" after it writes something:

1. Claude runs marky push <file> and hands you a marky.im/canvas/<slug> link.
2. Open it. Hover any element, click, leave a comment. Share the link — anyone comments as a guest, no sign-up, live cursors.
3. Tell Claude "address the canvas" (or set it live) — it reads each thread, edits the source, and pushes a new version on the same link. Old versions are kept.

You talk; Claude runs the commands. You never touch the CLI yourself.

What's in the box

• The marky skill — teaches Claude the whole loop: publish, read comments, reply on the canvas, mark threads done, push revisions, roll back. Claude loads it on its own when you say "marky it" / "share this for feedback" / "what did they comment".
• The marky CLI — a thin HTTP client (no keys — it starts as a persistent guest stored in ~/.marky, and marky login opens your browser to sign in, one sign-in covering web + CLI, when you want to keep canvases). push, watch, inbox, reply, resolve, mode, claim, and the rest.

Modes

A canvas has one mode, and Claude sets it from how you talk:

Mode	Viewers comment	Claude acts on comments
readonly	no	—
feedback (default)	yes	no — parked until you say go
live	yes	yes — works them as they arrive

"Go live" arms a realtime doorbell so Claude reacts the moment you comment; "park it" stops it.

Privacy & telemetry

The CLI starts as an anonymous guest — no account, no email — until you choose to marky login (which opens your browser) to keep canvases under a real account. It sends basic usage events (e.g. canvas.published) to marky.im so I can see what's used; set MARKY_NO_ANALYTICS=1 to turn that off. It only ever talks to marky.im (override with MARKY_BASE_URL).
