Show HN: Pinpoint – Visual feedback for AI coding agents

[maferland]

I built Pinpoint because I was tired of typing out feedback on the visual work my AI agent did. I want my agent to be autonomous, so having it ask for feedback through a UI felt genuinely better. Dropping a contextual comment on each screenshot is much closer to how you'd give feedback on a design in Figma. It also does side-by-side comparison, which is really helpful, having the before/after screens lets the human in the loop (us!) give better feedback.

It's just screenshots and comments, the same way Plannotator is just a plan and comments, and that's still a successful product. I think there's real value in building a decent UX for this. Chat is the current paradigm for AI agents, but it doesn't have to be, and this is my attempt at changing that.

There's nothing wildly clever going on here. It just works really nicely for me, the same way Plannotator does. Would love your feedback.

Pretty nice to have a figma-esque interface to add comments that goes directly to your agent,

I've tried this one and https://github.com/kunchenguid/lavish-axi (which is similar but more for design documents) and I really like the "comment directly in document" to have modifications.

Impressive @maferland
