Speaker 3: Design team approved the final mockups yesterday.
Speaker 2: Great. I'll update the project board with the new dates.What is AI voice transcription?
AI voice transcription turns spoken audio into written text using a speech-to-text model instead of a human typist. You record or upload audio, the model listens for words and sentence boundaries, and it returns a readable transcript. The faster and more accurate the model, the closer the text gets to what was actually said.
BrainFlow uses cloud-based AI transcription. Your recording uploads to a secure service, gets transcribed, and the text syncs back to your private library. Because the work happens in the cloud rather than on your phone, you get strong accuracy across accents and languages without draining your battery or waiting on a slow device.
BrainFlow is built for the messy, real-world audio most people actually have: a quick idea on a walk, a meeting with three people talking over each other, a lecture from the back of the room, an interview on a noisy street. The same engine runs every other BrainFlow workflow, including voice notes and meeting notes.
What you can transcribe
One transcription flow covers most of the spoken material you deal with in a week. You record or import the audio, BrainFlow transcribes it, and you get back text you can search, edit, and export.
- Voice notes and ideas — capture a thought out loud and read it back as text. See voice notes to text.
- Meetings — transcribe a stand-up, a client call, or a planning session, with speaker labels for meetings when more than one person is talking.
- Lectures and talks — record a class or a conference session and keep a searchable transcript to study from later.
- Interviews — transcribe a one-on-one so you can quote it accurately instead of scrubbing the audio.
- Imported audio and video — drop in a file you already have, including MP3, M4A, WAV, AAC, FLAC, OGG, and video like MP4 or MOV.
- Dreams on waking — speak a dream before it fades and read it back later in a voice dream journal.
How BrainFlow transcribes your audio
Recording to transcript takes four steps. Most of it happens on its own once you stop talking.
Record or import
Tap record in the app, or bring in an audio or video file you already have. You can record offline; the audio is held safely and uploads once you are back online.
Upload to the cloud
Your recording uploads to a secure speech-to-text service over an encrypted connection. Nothing is sold or used for ads.
Transcribe and structure
The AI detects the language, transcribes the speech, and applies any custom keywords and speaker labels you set. In the same pass it drafts a title, a summary, suggested tags, and any tasks you mentioned.
Sync to your library
The finished transcript and notes land in your private library, backed up and searchable across your devices. Edit the notes, file them in folders, or export them whenever you like.
Speaker labels and custom keywords
Speaker labels mark who said what in a multi-person recording, so a meeting or interview reads as a conversation instead of one long block of text. They are opt-in: turn them on for the recordings that need them, and leave them off for a solo voice note where they would only add noise.
Custom keywords (also called keyterms) tell BrainFlow about the words it would not otherwise guess. Add the names of people on your team, your product names, industry acronyms, or anything spelled in a way the model might miss. With those terms in place, your transcripts spell them correctly every time instead of leaving you to fix the same word over and over.
Together these two settings handle the parts of transcription people usually have to clean up by hand. For meetings in particular, pairing labels with keywords is the difference between a transcript you trust and one you have to babysit. See meeting transcription with speaker labels.
Languages and file formats
BrainFlow transcribes audio in many languages and detects the language for you, so most recordings need no setup at all. Record in the language you think in; you do not have to tell the app which one it is.
You can transcribe a fresh recording or import audio and video you already have. Supported audio includes MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, and WEBM. Supported video includes MP4 and MOV, with BrainFlow pulling the speech out of the file. That makes it easy to transcribe a voice memo from another app, a recorded call, or a video you took on your phone.
What BrainFlow transcription includes
Most transcription tools stop at the text. BrainFlow returns a full note from a single recording.
| You get | Included | Notes |
|---|---|---|
| Full transcript | Yes | Accurate text from your audio in many languages |
| Title | Yes | A short, descriptive title drafted for you |
| Summary | Yes | A markdown summary of what you said |
| Extracted tasks | Yes | Action items with sub-tasks and checkable status |
| Suggested tags | Yes | Tags applied automatically so notes stay findable |
| Speaker labels | Optional | Turn on for multi-speaker recordings |
| Custom keywords | Optional | Add names, acronyms, and jargon for accuracy |
| Export | Yes | Markdown archive, email, or Notion |
Every transcript becomes a searchable, exportable note in your private library.
Private storage and export
Your recordings and transcripts sync to your own private cloud library, backed up and available on every device you use. They are encrypted in transit, and we never sell them or use them to target ads. You can export or delete anything whenever you want, and clear local copies from a device when you are done with them.
To find an old transcript, search by keyword across your titles, summaries, transcripts, tasks, and tags. The exact phrase someone said is enough to surface the right note. Organize with folders (one per note, with an Inbox by default) and as many tags as a note needs.
When you want a transcript out of BrainFlow, export it as a Markdown archive, send it by email, or push it to Notion. You can start as a guest with no signup and later claim your library with Apple, Google, or an email code to sync across devices. The same library handles shorter spoken thoughts as voice notes to text, and feeds AI meeting minutes when more than one person is talking.
Transcription FAQs
Which languages does BrainFlow transcribe?
BrainFlow transcribes audio in many languages and detects the language for you, so most recordings come back accurately with no setup. Record in the language you think in; you do not have to tell the app which one it is.
What audio and video formats can I upload?
You can upload MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, and WEBM audio, plus video files like MP4 and MOV. BrainFlow pulls the speech out of any of them, so you can transcribe a recording from another app or a video from your phone.
How long does transcription take?
Most recordings come back soon after the upload finishes. Longer recordings take a little more, but you are not waiting hours. The work happens in the cloud, so it does not depend on how fast your phone is.
Can I edit the transcript after it's generated?
Once processing finishes you can edit the generated notes and summaries. The raw transcript stays read-only so the speaker labels and timing keep matching the recording, but the note you work from is fully yours to change.
How do custom keywords improve accuracy?
Add your acronyms, product names, people's names, and other jargon as custom keywords. BrainFlow then spells those terms correctly in every transcript instead of guessing, which is especially helpful for technical or industry-specific recordings.
Does BrainFlow label different speakers?
Yes, but it's opt-in. Turn on speaker labels for a multi-person recording and BrainFlow marks each segment by speaker so the conversation is easy to follow. Leave it off for a solo voice note where labels would only add clutter.
Where is my audio processed?
BrainFlow transcribes your audio in the cloud over an encrypted connection, then stores the recording and transcript in your own private library, backed up and synced across your devices. We never sell it or use it for ads. You can export or delete it anytime, and clear local copies whenever you like.
Is my audio private?
Yes. Your recordings and transcripts live in your own private cloud library, encrypted in transit. We never sell them or use them to target advertising. You can export everything or delete what you want, and you can start as a guest with no signup.
Do I get more than a plain transcript?
Yes. A single pass returns the full transcript plus a title, a markdown summary, suggested tags, and any tasks you mentioned, complete with sub-tasks and checkable status. Everything is searchable by keyword and exportable as Markdown, by email, or to Notion.
