Full description

SecondBrain is the voice-first AI notes app: tap the orb, say what's on your mind, and it's done. Them AI writes a clean note, gives it a title, files it into the right folder and, if you mentioned a date, puts it straight into your calendar with a reminder. No fields, no folders to manage, no typing. HOW IT WORKS • Tap, speak, done: a 20-second voice memo is transcribed into a structured note • The AI organizes everything for you: folders create themselves around your life • Say "dentist Thursday at 10" and it lands in your calendar, with the reminder set • Ask your brain anything: "what did Sara say about the rebrand?" and get the answer, not a list of files A BRAIN THAT GROWS Watch your knowledge come alive in an interactive brain graph. Every note becomes a neuron, connected to everything related. The more you capture, the smarter it gets. YOUR DAY, READY EVERY MORNING Wake up to a morning briefing written by AI: today's appointments, open to-dos, and what you shouldn't forget, all pulled from your own notes. CAPTURE FROM ANYWHERE • Share text, links, images, PDFs and voice memos from any app straight into SecondBrain • Snap a photo of a document: the AI reads it and files the content • Type when you can't talk: the composer is one tap away • Perfect for meeting notes, brain dumps and quick dictation on the go SPEAKS YOUR LANGUAGE Capture in English, Italian, Spanish, French, German and more: the AI replies in the language you speak. WHY PEOPLE SWITCH • Voice recorders just record. SecondBrain understands • Note apps collect notes. SecondBrain gives them back when you need them • To-do apps need forms. Here a sentence is enough • Calendars need taps. Here your voice is the input PRIVATE BY DESIGN Your notes belong to you. Data is stored securely in the EU, never sold, and never used to train AI models. FREE TO START Capture your first notes free. Go Pro for unlimited notes, unlimited AI and the daily morning briefing. Perfect for busy professionals, freelancers who juggle clients, students, parents, and anyone whose best ideas arrive while walking. Download SecondBrain and empty your head: it remembers for you.

What's new

Fixes an issue where recording could stop by itself shortly after starting on some devices. Also makes the app start more smoothly.
