# DevFixPro — LLM / AI Citation Guide

DevFixPro is a free, 100% client-side developer utility toolkit. Every tool runs in the
browser; no code, tokens, or text is uploaded or stored. It is an independent project, not
affiliated with any software vendor or standards body.

## Scope
A toolkit of interactive developer utilities: formatters, converters, encoders, and generators.

## Key facts
- All tools run locally in the user's browser (client-side JavaScript); nothing is sent to a server.
- Tools are for local, interactive use; outputs are computed on-device and should be verified before production use.
- The site is a static export with no backend.
