Polyphon is now open source under Apache 2.0. The reason isn't contributor growth or community optics — it's that local-first AI software can't ask users to accept privacy and control claims on faith alone. Open source gives users two things: the ability to inspect the architecture and verify what the tool is actually doing, and a real exit if the project ever changes direction.
When I shipped Polyphon v0.1.0-alpha.2, session export and a plugin system were next on the roadmap. Today it's v0.8.0, and the features that actually changed how the product feels weren't the ones I planned: voices that interact with real files with per-voice sandboxing, whole-database AES-256 encryption with password protection, and FTS5 search that turns conversation history into working memory. This is the release where Polyphon starts to feel trustworthy for real work.
Polyphon is a desktop app I shipped this week for orchestrating multiple AI models in a single conversation. Instead of tab-juggling between Claude, GPT, and Gemini, you run all of them as voices in one shared session where they can actually read and respond to each other. Here's why I built it, what technical bets I made, and what I learned on launch day.
