Point at it.

Paste a screenshot, tap the spots that matter and leave a note on each. Then share one link. Your AI agent sees every note on the exact spot it’s about.

Invite‑only for now. We’ll email you when there’s room.
An example Posterize board. A screenshot of a cabin booking app has three numbered pins on it, and each pin has a note, listed below.
  1. A1

    Make Reserve full width and give it more room. Next to the price it’s easy to miss.

  2. A2

    Check-out should default to two nights after check-in.

  3. A3

    Show the total with fees here, not on the next screen.

Tap the screen to add a pin.

Here’s how feedback usually sounds.

so the button thing on the right kind of gets lost, and the dates are annoying? also the price feels off somehow. can you just make it better

Your agent has to guess which button, which dates and what’s wrong with the price. On a board, each one is a pin with its own note.

One link carries all of it.

Send the link to the AI agent you build with. It gets the images and every note, each one tied to the spot it’s about, in an order it can work through.

Screen recordings work too.

What the agent receives from the link: one screenshot and three callouts, each with its position on the screen and its note.

Say it once.

A note that sits on the exact spot doesn’t need a follow-up. Nobody has to ask which button you meant.

Keep moving.

Pointing is quick, so you can hand off a problem the moment you see it and get back to what you were doing.
