Maple
Maple's core claim - conversations encrypted on-device and processed in secure enclaves the operator itself cannot read - is a genuinely different architecture from most AI chat products, and using only open-weight models backs that privacy pitch instead of undercutting it. The main app was blocked from direct verification during this review, so the pricing and some feature claims here rely on the vendor's own blog rather than the live app.
Pros
- On-device encryption plus secure-enclave processing is a concrete, named architecture, not just a privacy claim
- Runs only open-source/open-weight models, which is checkable in principle
- Desktop apps for macOS and Linux exist alongside web and iOS
- Ships a developer-facing encrypted API (Maple Proxy), not just a consumer chat app
Cons
- The main application site was not directly reachable during this review
- No confirmed headquarters or country for the operating company
- Free tier is capped at 10 chats per week, quite low for daily use
