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

SecondBrain
Launched this week
New since our June launch: SecondBrain is rebuilt around your voice, and it now runs in your browser too.

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.

As an engineer with ADHD having a short memory is a mess, I always used to miss calls, forget new great ideas loose documents and so on.
I built this for myself, but now more than 3500 users are actively using it, and feedbacks are great. Give it a try and let me know!
@fed3c3sa one memory shared across Claude, ChatGPT and Cursor is what caught my eye. Right now I paste the same context into every tool. Do I need to set it up separately for each app or does it just work once it’s connected?
This is really cool! :) I will show my husband haha. I'm curious: how does SecondBrain decide which folder a spoken note belongs in?
