Maple Chat is a private AI chat app. Your chats are end-to-end encrypted, so Maple cannot see them. Ask about your health, your money, a contract or a hard conversation, and get answers from leading open AI models without handing your words to anyone. No one at Maple can read your chats. They are encrypted on your device and decrypted only inside a hardware-isolated secure enclave running open-source code you can verify. Since we can't read them, we can't train on them either. THE BEST OPEN MODELS, RUNNING PRIVATELY Maple runs leading open models in secure enclaves in the cloud. You get the speed and intelligence of cloud AI without draining your battery, and without giving up your privacy. Switch models in any chat. New models are added as they are released. WHAT YOU CAN DO • Chat about anything: long, thoughtful conversations on the topics you would never type into another AI app. • Analyze documents: attach a PDF or file and ask for a summary, the key points or what to watch out for. • Ask about photos: snap a picture and ask what you are looking at. • Talk instead of type: voice mode for fast, natural input. • Search the web: live, ad-free web results inside your private chat. • Pick up anywhere: your encrypted chat history syncs across iPhone, iPad, Mac and the web. BUILT FOR THE CONVERSATIONS THAT MATTER • Health: understand a diagnosis, prepare questions for your doctor, organize notes. • Money: plan a budget, prepare for tax season, compare options. • Legal: read a lease or contract and understand what you are agreeing to. • Work: draft sensitive emails, summarize confidential documents, think through a decision. • Personal: journal, process a hard day or practice a difficult conversation. • Travel: translate menus, signs and conversations as you go. PRIVACY YOU CAN CHECK • End-to-end encryption for every chat. • Models run inside attested secure enclaves, so no third party can read your chats. • Your encryption key is managed for you inside the secure enclave. • Your chat history is stored encrypted. • Open-source code and cryptographic attestation let you verify how it works, at maple.ai/proof. FAIR QUESTIONS Can Maple read my chats? No. They're only decrypted inside a secure enclave. Will my chats train your models? We'd have to read them first. We can't. What if someone demands my chats? They'd get encrypted data. So would we. How do I know you're not bluffing? The code is open source. Check it yourself at maple.ai/proof. FREE TO START Create an account and start chatting in seconds.
