MindWork AI Studio
A rare thing: a genuinely free cross-platform desktop chat client where you hold the keys and no subscription sits in the middle. The trade-off is that you handle provider accounts, billing and key hygiene yourself, and the licence is source-available rather than fully open.
Pros
- No subscription, and free for commercial use as well
- Wide provider coverage including local inference backends
- Native builds for macOS, Windows and Linux
- Source is on GitHub, with an open ERI spec for private data retrieval
Cons
- You must obtain and manage an API key for every provider you use
- FSL-1.1-MIT restricts competing commercial use until it converts to MIT
- Single-user desktop only, with no hosted or mobile version
