Tresor is a privacy-first AI assistant that processes your conversations inside secure, sealed environments so that nobody — not even Tresor — can read your messages.
Sign up for Tresor with your email and password, verify your email with a 6-digit code, and optionally enable two-factor authentication for extra security.
Send your first message to a private AI in Tresor — type a question, hit Enter, and get an encrypted, verified response.
Tresor offers several AI models with different strengths. Choose Instant mode for quick answers or Thinking mode for complex reasoning — all running inside secure enclaves.
Start new conversations, organize them in the sidebar, search your history, rename or delete chats — all titles and content are encrypted.
Upload documents and images directly into a conversation or project for the AI to analyze, summarize, or reference — everything stays encrypted end-to-end.
Projects let you group related conversations and files into focused workspaces with custom instructions, so the AI understands your context.
Upload documents to a project so the AI can reference them across all conversations in that project — files are encrypted, persistent, and processed inside the enclave.
Tresor offers several AI models with different strengths. Choose between Instant and Thinking mode, compare models, and switch at any time — all running inside secure enclaves.
Enable web search to let the AI research the internet on your behalf. You approve each search before it happens, and your identity stays private.
Create a workspace to collaborate with your team. Invite members, share encrypted projects, assign roles, and use the audit trail for compliance — all with zero-access privacy.
Tresor uses zero-access architecture: your messages are encrypted in your browser, processed inside sealed hardware enclaves, and stored as ciphertext that nobody — including Tresor — can read.
