Why You Need JamPack

AI models and code review tools have limits – JamPack helps you work around them.

The Problem

GPT, Claude, and other AI models can't read more than 10 files at once.

  • Real projects have dozens or hundreds of files
  • Manual copy-pasting is tedious and error-prone
  • Context is lost without proper file organization

JamPack's Solution

One simple drag-and-drop to combine multiple files into a perfectly formatted text file.

  • Preserves file paths and formatting automatically
  • AI-friendly output that maximizes token efficiency
  • Customize file order for logical presentation
