As answered by people managing CalyxOS and ShadowGit.
ShadowGit's answer:
ShadowGit is the only tool where AI assistants can directly search your code history to debug faster while using 50% fewer tokens. Auto-captures every change without touching your main git repo. Built specifically for AI-assisted development.
ShadowGit's answer:
Electron is the primary technology being used.
ShadowGit's answer:
ShadowGit is the only tool built specifically for developers using AI. Unlike generic backup tools, your AI can actually search the history to debug faster and use 50% fewer tokens. Separate shadow repo means your main git stays clean. 100% local.
ShadowGit's answer:
AI-Accelerated solo developers that use AI coding assistants daily (Claude, Cursor, Copilot), experienced enough to feel the pain (2-10 years of coding) and that want to move fast, ship often and experiment constantly.
ShadowGit's answer:
I built ShadowGit after losing 3 hours of work to a bad AI refactor. Started as a personal backup tool, but when I added MCP integration so AI could search the history, debugging time dropped 80%. Had to share it.
