What is it?

Snip is a visual review layer for AI coding agents. Once installed, a command such as snip setup configures Claude Code (and Cursor, Windsurf, Cline) so that architecture, data models and flows are rendered as Mermaid diagrams or HTML previews instead of text. The user reviews the output on screen, either approving it or annotating it with circles, arrows and notes, and the agent receives structured JSON with the decision and annotations.

Snip also works as a standalone screenshot and annotation tool. Capture shortcuts support region select and window snap, a quick mode copies to the clipboard, and the editor offers rectangle, arrow, text, blur and AI segmentation tools. Saved screenshots are named, categorized and tagged by a local vision model run through Ollama, and can be found with semantic search.

The project is a CLI plus an MCP server for agents without shell access. It runs on macOS 14+ and Linux under Wayland, and its core AI features run locally without cloud APIs.

Key features

  • 01Renders Mermaid diagrams and HTML previews for AI coding agents
  • 02Annotate screenshots with shapes, arrows and text, then send feedback back to the agent
  • 03Configures Claude Code, Cursor, Windsurf and Cline via snip setup
  • 04Screenshot capture with region select, window snap and clipboard quick copy
  • 05Local AI categorization and semantic search of saved screenshots through Ollama
  • 06Includes an MCP server for agents without shell access

Use cases

  • Reviewing architecture diagrams or data models that Claude Code generates before accepting them
  • Marking up UI previews with feedback that the agent can act on in the next iteration
  • Searching a large personal screenshot library by describing what was on screen

Quick start

  1. 1

    Install on macOS with Homebrew

    brew install --cask rixinhahaha/snip/snip
  2. 2

    Configure Claude Code to use visual output

    snip setup

Things to know

  • Requires macOS 14+ or Linux (Wayland), so Windows is not supported.
  • macOS builds are Apple Silicon DMG only in the README; Linux is available as AppImage or deb.
  • Optional AI organization needs a local Ollama vision model installed.
