Product feedback has a strange habit: it lives everywhere except the product. A broken button becomes a Slack thread, an annotated screenshot, a ticket with three paragraphs describing where to click.

And here's the part that changed recently: most of those fixes aren't waiting on a developer's calendar anymore — they're waiting on a good enough description. Coding agents can handle a lot of this work, if someone tells them exactly where and what.

Sidenote makes the description automatic. You get a browser extension; you click the exact element on the live page and leave your note. The pin captures the selector, the markup, and a screenshot along with it — an annotation like that is 90% of an agent's task spec.

So a review session becomes a work order. Open the project, copy the whole backlog as one agent brief, and paste it into Claude Code or Cursor to work through — or sync it to Linear in one click, every pin an issue a developer or an agent can pick up.

It's in private beta and some edges are rough. But pin → brief → fixed is real today; it's how we build Sidenote itself. If your team gives a damn about the details, I'd love your notes.
