Mutable AI
What it is: Production-grade AI for large codebases. Semantic search, automated refactoring, test generation. Enterprise-ready.
What It Does Best
Ask about your codebase. "Where do we handle payments?" AI finds it across millions of lines. Semantic, not keyword search.
Refactor safely. AI suggests refactors, shows impact analysis. What will break. What tests need updating. Confidence before changing.
Auto-document code. Generate docstrings, update READMEs. Keeps documentation in sync with code changes.
Pricing
Individual: Free for personal projects
Team: $20/user/month
Enterprise: Custom pricing (SSO, security)
When to Use It
✅ Large legacy codebase to understand
✅ Major refactoring projects
✅ Need to onboard developers faster
✅ Documentation always out of date
When NOT to Use It
❌ Small projects (overkill)
❌ Just want autocomplete (use Copilot)
❌ Solo developer (team features wasted)
Bottom line: Serious tool for serious codebases. Not for writing your next weekend project. For teams maintaining complex systems long-term.
