Build your second brain on your phone, just by talking

11 followers

Tap and talk. SecondBrain writes a clean note in your words, files it in the right folder, and turns dates into calendar events and reminders. It never guesses a time, it asks. Later, ask anything and it answers from your notes. Pro adds a shared memory for Claude, ChatGPT, Gemini and Cursor over MCP, so every AI you use knows your context. iPhone, Android and web, in 5 languages. Free plan: 10 notes and 3 AI requests a day. Your notes are not used to train AI models.
This is the 2nd launch from SecondBrain. View more

Build your second brain just by talking, now on the web too
New since our June launch: SecondBrain is rebuilt around your voice, and it now runs in your browser too. Tap and talk: it writes a clean note in your words, files it, and turns dates into events and reminders. No time given? It asks. Share links, PDFs and photos from any app, then watch it work live. Ask anything and the answer streams from your notes. Pro adds one shared memory for Claude, ChatGPT, Gemini and Cursor over MCP. iPhone, Android and web. Free: 10 notes and 3 AI requests a day.
