MashuPack solves a small but constant annoyance: getting the right slice of a codebase into a browser AI chat without messy copy-paste or hitting file limits. Select exact files or subsystems from a local repo, and MashuPack compiles them into one structured text file ready to paste into ChatGPT or Claude.
## How it works
It runs entirely in the browser — no backend, no account, no repo upload. Your code never leaves your machine. Built for planning, debugging, architecture review, and codebase understanding: the workflows where you want to reason over a chunk of a project with a chat model rather than hand it to a coding agent.
## Why it matters
There’s a whole micro-category here (Repomix, files-to-prompt, code2prompt) because the friction is real: chat models have context limits and no filesystem access, so feeding them code means packing it first. MashuPack’s no-upload, browser-only stance is the privacy-conscious take — useful for anyone who can’t paste proprietary code into a SaaS packer. Small tool, frequent use.
