A note-taking app for class
Lecture halls are a cocktail party: the professor across the room, people talking, chairs, doors. Add a heavy accent and most apps give up. Verbat records the room, follows the voice you choose, and writes every word. After class, it turns the lecture into notes you'll actually reread.
Free during the pilot. iOS first. One email when it's ready.
The problems
The cocktail-party problem. The professor is five meters from your phone, someone drops a backpack, the room echoes, people whisper. Your phone hears all of it, mixed into one wall of sound. Verbat separates the voice you care about from the room.
A professor's English carries an accent you're still learning to hear. Most transcription apps guess, and the guess lands wrong. By the time you decode the sentence, the lecture has moved on. Verbat is built for accented English, and we publish the numbers.
The solution
Verbat sits in your pocket during class. It hears everything, writes it down in real time, and keeps each voice separate so you can always tell who said what.
The whole class, start to finish. You never have to write fast again.
Read along while the professor speaks, through the noise and the accent.
Each speaker gets their own clean transcript. Read just the professor's words, without the room.
After class, the lecture becomes clean, organized notes: the key ideas, in order, ready to review. Not a transcript dump.
Hear it yourself
A real lecture, recorded the way it actually sounds: professor at a distance, room noise, accented English. During class it's a wall of sound, and most apps leave it that way forever. After class, Verbat separates the voices and writes each speaker clean. Here is the same moment, as typical apps left it and as Verbat returns it.
The recording: a real Korean-accented lecture, captured from the back of the room. The professor is far from the mic. The room is alive.
Same audio, same moment, same conditions. Typical apps is the best result from the other engines we tested. Full numbers below.
This recording has two voices talking over each other. Live captions mix them into one mess, and most apps leave it that way. After class, Verbat separates the recording by speaker: tap a track to hear one voice alone.
Tap a voice to hear it alone. Voices are separated cleanly, one track per speaker.
Not a live effect: separation runs after the recording finishes.
After class
Nobody rereads a transcript dump. After class, Verbat separates every voice, writes each speaker clean, and condenses the lecture into the notes you actually want: the key ideas, organized, ready before your next exam.
The lecture is condensing.
The benchmark
No marketing numbers. Every score below comes from the same 20-second clips, run through real classroom acoustics and real classroom noise at three levels. Lower is better: 0% means every word right, 100% means word soup.
Honest note: these scores come from our far-field test rig: real room acoustics,
real classroom babble, phone-style capture. The test set mixes real lecture recordings with synthesized
accented voices where real recordings are not available yet, marked above. Real classrooms are the next test.
Methodology: same 20-second clips, three noise levels, measured August 2026. Typical apps in the demo above =
the best of the other engines we tested under identical conditions. No engine names here: you don't buy engines,
you buy your lecture back.
These are the first published numbers, not a ceiling: the pipeline improves continuously, we re-run the
benchmark every time it does, and the scores on this page get updated as they get better.
