Frequently Asked Questions
Do I need an account?
No signup to start. BrainFlow opens as a guest, so you can record right away. When you're ready, claim an account with Apple, Google, or an email code to back up your notes and pick them up on another device.
Where is my data stored?
Your notes, transcripts, and recordings live in your own private BrainFlow library in the cloud, backed up and synced across your devices. It stays yours: export or delete it anytime, clear local copies when you like, and we never sell your data.
Can I upload existing audio?
Yes. Import audio or video from your device (MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, MP4, MOV, and more, up to about 100 MB), and BrainFlow pulls out the speech and writes it up.
Can I continue a note later?
Yes. Add more recordings to a note over time and BrainFlow keeps its history. Recordings still processing wait for you in your list, so nothing gets lost.
Can I export my notes?
Anytime. Export a note or your whole library as a Markdown archive, send it to your email, or sync it to Notion. Your notes belong to you.
Does it work offline?
You can record offline. BrainFlow safely holds new recordings until you're back online, then uploads and writes them up. Browsing and organizing your full library need a connection.
Is there dark mode?
Yes. Choose light, dark, or match your system. Dark mode is tuned for comfort in low light.

What early users are saying
Alex Morgan
Product Manager · SaaS
“Half my PRD comes out of user calls, and I used to lose most of it in the moment. Now the key points are sitting in bullets by the time I open the doc.”
Hannah Fraser
Teacher · Secondary School
“Parents evening is fifteen conversations in a row, I jot quick notes between them and get something coherent later, instead of guessing which parent said what.”
Luca Martínez
Podcaster · Weekly Show
“I talk through the next episode out loud while I cook or do chores. By the time I sit down to prep, the rough parts are already sketched and I edit from there instead of starting from scratch.”
Sam Lee
Content Creator · Independent
“My best ideas appear on walks and usually are gone before I get home. Now I talk them out straight away and there's an outline waiting. The titles it suggests I mostly rewrite so I can find them easier, but it's still super useful!!”
Jordan Rivera
Registered Nurse · Clinical
“Handover gives me about two minutes. I take notes through the shift and then skim the summary right before, so I'm not deciphering my own scribbles later.”
Daniel Morris
Attorney · Boutique Practice
“I'd leave myself voice memos after client meetings and never play them back. Now I get a summary with the follow-up tasks pulled out, which was the only part I needed anyway.”
Nadia Park
Journalist · Freelance
“The transcripts aren't flawless, but they're close enough to search for the one line I half-remember. And the notes are very good and concise.”
Taylor Brooks
Undergrad
“I talk through whatever's on my mind and read it back later as something I can actually use.”
Priya Rao
Therapist · Private Practice
“The few minutes between clients are when things occur to me. I say it out loud so it's not filtered by how fast I can type, and read it back at the end of the day when I do my notes.”
Erin Brooks
Program Manager · Non-profit
“We're four people, so time stretched as it is. I upload my field notes and get a short brief I can send the team without spending all afternoon on it.”
Ishaan Patel
Founder · Seed-stage startup
“Every meeting we do gets recorded now and then put in our Notion. No more figuring out why we decided to do a certain thing from some half-assed notes.”
Aiko Tanaka
International Student · Computer Science
“My tutor sessions go very fast and English is my second language, so I miss bits often. I play the recording back and read the summary in Japanese. Revision is so much easier.”
Maya Ortiz
Art Student · Studio Program
“After a crit I ramble into my phone on the walk home. By the time I'm back in the studio it's readable notes, not some blurry photos of a whiteboard.”
Taylor Brooks
Student Dorm 2
“I talk through whatever's on my mind and read it back later as something I can actually use.”
Clarence Nguyen
Attorney · In-house
“I dictate whatever's on my mind between calls. By later it reads well enough to forward to the team without a rewrite.”
Riley Chen
PhD Researcher · Human-Computer Interaction
“I run a lot of interviews and was drowning in audio files. Everything's tagged and searchable now, so when I'm writing up I can find the exact moment I need.”
Beth Carter
Undergraduate Student · Economics
“I tape our study sessions and get back a summary plus a list of what to review before the exam. Works well :)”
