PatchLook lightweight diff viewer

A tiny Git change and commit viewer built for the AI-coding era

Problem

Developers keep an IDE open next to Codex just to review local changes and history because Codex diffs are hard to use. A second IDE eats memory and spikes CPU in the background; free or open-source alternatives are either paid, ugly or bloated.

Solution

A very lightweight cross-platform Git viewer focused on uncommitted changes, commit history and file-level diffs. It lives in the tray with low memory, refreshes as AI tools edit files, and filters by folder or author.

Users

Developers using AI coding tools who review local changes often; users on low-spec machines

MVP

Local repo changes and commit history list; file-level diff view; auto refresh and tray mode; filter by folder/author; very low resource usage

Revenue

Free and open-source core; one-time Pro unlock for multi-repo workspaces, themes and exports

Why now

AI coding tools generate many local changes, making diff review a frequent need; lightweight desktop stacks are mature enough for an indie to differentiate
