What is it?

EditHere is a desktop tool for telling an AI assistant exactly where and how to change a user interface. You capture a screen region, pin numbered comments to points, boxes or the whole image, or split the page into movable components and drag them to new positions. Each change is recorded with its real before-and-after coordinates, so the assistant gets precise pixel locations instead of a paragraph of directions.

For video and animation, you pause on a frame, annotate it, and the export keeps timestamps and frame captures for each note. Screenshots, element detection, OCR and editing run locally using built-in system engines on Windows and macOS. EditHere does not call any model itself; the feedback is delivered as JSON and images that you paste into any AI tool, or passed through the included edithere-cli and skill so the assistant can open the editor and wait for your submission.

Windows 10 1809+ is the supported platform, with macOS 14+ and Linux (Ubuntu 24.04) marked as previews.

Key features

  • 01Hover-to-select screen elements with a magnifier and pixel readouts.
  • 02Numbered point, box and global annotations exported as structured JSON.
  • 03Explode a page into components and drag, scale or set exact coordinates.
  • 04Pause video frames to annotate, with timestamps and frame images in the export.
  • 05Local OCR using Windows OCR or macOS Vision, with no upload.
  • 06Command-line interface and skill for AI tools to open the editor and receive feedback.

Use cases

  • Telling an AI assistant to move or resize buttons, cards or charts in a web or app UI.
  • Reviewing game HUD or animation timing by annotating specific frames of a video.
  • Marking up design mockups with precise positions before handing them to a coding agent.
  • Walking through a long scrolling page and sending the stitched screenshot with comments.
