Best open-source models in one private chat
No juggling subscriptions. Switch between leading AI models freely. All conversations protected by the same TEE encryption.
Privacy in AI isn’t optionalit is essential
Your conversations never leave your encrypted enclave.
Encrypted Chat
This conversation is encrypted. Only you can read it.Message to Wisp
Features
Real-time web search, minus the tracking
What you search stays yours. Brave Search provides results without profiling you or building a search history.
Context across all your chats
Your AI remembers. WISP doesn’t. Context is held inside the enclave — never logged, never stored outside your session.
Upload documents. Get insights. Keep ownership.
Your files stay yours. Analyse contracts, reports, and data with full TEE protection. Nothing leaves the enclave.

FAQ
A Trusted Execution Environment is an isolated region inside a CPU where code and data are encrypted in memory and sealed off from the host OS, hypervisor, and cloud operator. For AI, it means your prompts and responses are processed in hardware no one — not even us — can peek into. You get cloud-scale models with on-device-level privacy.
Yes. Every enclave produces a cryptographic attestation that proves which exact code is running inside it before your session starts. You can verify the attestation against our published, open-source binaries. If the build doesn't match, your client refuses to send data — so privacy isn't a promise, it's a pre-condition of the conversation.
Hosted assistants run on infrastructure where the operator can read, log, and train on your conversations. Wisp runs the model inside a TEE, so your chats are never visible to us, never stored on a server in plaintext, and never used for training. Same frontier-quality answers, none of the data exhaust.
Wisp supports leading open-weight models (Llama, Mistral, Qwen, DeepSeek) plus hosted frontier models routed through the enclave. Built-in tools include web search, document Q&A, code execution, and image understanding — all running inside the TEE, so the tools see your request but no third party ever does.
