About SecondBrain: AI Voice Notes
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.

Bro, i woke up thinking I wanted to build the exact idea with exact technologies and decided to check if anyone had done something similar. you did an amazing job and i decided to use your app instead of building one. very cool features, and nice design and i believe it will get better. just a suggestion, think abou...
Amazing app that files and sets up folders for your voice notes automatically. It can integrate with its calendar and set reminders for you. I use it to brain dump my random thoughts so that I wouldn't forget anything and they get sorted and organised automatically. Support is superb too; had a glitch due to OS upda...
This app is one of a kind. I’m not even going to complain about the limited AI use. It’s annoying, but the app is still well worth it, even if I have to wait 24 hours between entries. Keep working on it and making it even better—it has so much potential!
