Your voice never leaves the phone — wake word and speech-to-text both run on-device. The resulting conversation text is sent to Anthropic's Claude API, using an API key you supply yourself, so it can think and respond; every transcript is also written to your own Obsidian vault before that request goes out. Those requests carry a web-search tool: Anthropic's servers may run web searches drawn from your conversation to ground the answer before it streams back. If you connect a Notion integration, text from tasks you ask it to save there is sent to Notion's API using a token you provide. Every outbound call — to Anthropic, including its web search, or to Notion — runs on a credential you entered yourself, and every one of them is disclosed on this page.

The waitlist email form on this site is operated by Buttondown; an address you submit there is used for release announcements and nothing else.
