Questions & Answers

As answered by people managing Postbox and ShadowGit.

What makes your product unique?

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.

Which are the primary technologies used for building your product?

ShadowGit's answer:

Electron is the primary technology being used.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.
