No typing, no filing, no formatting. The pipeline runs the moment you stop talking.
Speak
Tap record and talk like you would to a friend — rambling welcome.
Transcribe
On-the-spot transcription that keeps up, even when you switch languages.
Structure
Title, summary, tags, tasks, and events are extracted automatically.
Act
Tasks land in your list, events on your calendar — one tap to schedule.
Everything your voice deserves
A full second brain built around the fastest input you have.
Notes that write themselves
Every recording becomes a titled, tagged, summarized note with key insights — searchable and filed into folders automatically.
Tasks & calendar, extracted
Deadlines, priorities, places, and events are lifted straight out of your speech — one tap to schedule them on your calendar.
Knows who's speaking
Enroll a voice once and Hum names speakers in future recordings — meetings and conversations come out attributed, not anonymous.
Ask your notes
Chat with everything you've ever said. Answers are grounded in your own recordings, with citations back to the source note.
Speaks your languages
Multilingual transcription that keeps up when you switch languages mid-sentence — English, Chinese, German, and 100+ more.
Private by architecture
Your notes live in your own protected space — encrypted in transit, never sold, never used for advertising, deletable in one tap.
Your voice stays yours.
No ads. No tracking. No selling data. Voice recordings and transcripts are processed only to build your notes, and deleting your account erases everything — audio, transcripts, and voice profiles included. Read the Privacy Policy.
