Show HN: Mark edits on images, then send them to AI

1 point

5 months ago

While testing Nano Banana Pro, I tried a different habit: instead of explaining “change this area,” I simply marked the exact spots on the image. The results felt instantly more controllable, so I turned that workflow into a canvas-based editor that sends the image + marks to the model in one step.

Canvas-first editing: doodle/annotate directly on the image (circle/paint/point) to show where to change

One-click “image + marks → AI” loop, designed to reduce ambiguity and cut down retries

A few tuned presets that most people tend to like (e.g., 1-click contact sheet, 2D → 3D conversion)
