Stays on your device
AI chats and prompts. Mentria's built-in AI tools run the model on your device's graphics chip, so your questions, the answers and the pictures you show the AI are processed in your browser and not sent to a server. Files you open. Photos, videos, music, PDFs and documents are read inside the page. Tools that change a file give you a new copy to save, without uploading anything. Camera, microphone, motion and location. Phone tools read them inside the page while you use them, and the readings aren't sent anywhere. What you save. Notes, settings, learning progress, imported packs, the extensions you add, game saves and your Mentria identity live in this browser's storage. Clearing the site's data removes them. Backups. A backup is one encrypted file that you download and keep. Mentria never gets a copy, and nobody can open it without your passphrase.
What uses the network
Loading Mentria Every visit. Pages, pictures, music and app files come from the servers that host Mentria. Like any website, they see your IP address, the page you open and your browser's name. Mentria's pages have no analytics scripts, ads or trackers. AI models When you open an AI tool and its model isn't saved yet. The model downloads once and is saved in your browser, so the AI keeps working offline. The server sending it sees the download, as with any file. Comms, online chess and device sync Only when you use them. What you send is encrypted on your device first. To connect, your device and the other one see each other's IP address, and Mentria's relay helps them find each other. Messages for someone who's offline wait on the relay, encrypted, for up to 30 days. In Comms, turn on “hide my ip” to send everything through the relay, so the other person doesn't see your address. Model Mirror Only if you turn it on. Your browser shares AI model files with other visitors, peer to peer. As with any peer-to-peer sharing, they can see your IP address. Notifications Only if you turn them on for timers or Comms. Your browser maker's push service delivers an alert that only says Mentria. The details are filled in on your device. Posting to GitHub Only when you choose to post something, like a story or a bug report. You post it yourself, under your own GitHub account, and it's public there. AI Chat web search Only if you connect AI Chat to a search server you run yourself. Search questions go only to that server, which you control. Your browser's AI assistant Only if your browser has one and you ask it to use Mentria. Mentria offers it tools, like search and your note titles. What a tool returns goes to that assistant, which may run in the cloud. Extensions When you run one. Anyone can build an extension, so each one works in its own way, and some send what you give them over the internet. Check what an extension does before you use it, and only add ones you trust.
What Mentria's servers keep
Check it yourself
Open your browser's developer tools (F12, or Option-Command-I on a Mac) and choose the Network tab. Use any tool or chat with an AI model. Every request shows up in the list, with the server it went to. Once a model is saved, chatting with it adds no requests. You can turn off Wi-Fi and keep going. Read the code.
