What files can I upload?

Common audio and video recordings: MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, WMA, and video like MP4, MOV, M4V, WEBM, MKV, and AVI. For video we extract the audio track first. One recording per job, up to 500 MB.

What do the notes contain?

Always the same six sections: overview, outline, key concepts with the definitions the lecturer gave, examples & case studies, summary, and 5-8 review questions. Everything is written from the transcript - nothing is added from outside the lecture, and a section with nothing to report says so.

Are the review questions answerable from the lecture?

Yes - that is the rule they are written under. Each question comes from material the lecturer actually covered, so you can check your answers against the notes themselves. You can ask for exam-style questions in the instructions box if you want harder ones.

Do I also get the full transcript?

No - this tool returns the study notes, not the word-for-word transcript. If you want the full text of everything spoken, run the same recording through our audio to text tool.

How is pricing calculated?

6 credits per minute of audio. Because the length is not known until the file is processed, the upfront hold is estimated from file size at a typical bitrate for the format (about 1 MB per minute for MP3 audio, more for WAV, FLAC, or video). The minimum is 6 credits.

Are my recordings private?

Yes. Recordings run on our own servers, are never used to train any model, and are auto-deleted 7 days after the job finishes.

How it works

1Upload one recordingDrop in an audio or video file up to 500 MB - a lecture-hall recording, a recorded seminar, or an online class.

2We transcribe, then write the notesThe speech is transcribed on our own servers, then a language model writes study notes from that transcript - and only from that transcript.

Who uses this tool

UNIVERSITY STUDENTS

Lectures you can revise from

Record the lecture, upload it after class, and study from structured notes instead of scrubbing through audio.

EXAM PREP

Quiz yourself on every lecture

The review questions come from what was actually taught, so practicing them is practicing the exam material.

STEM COURSES

Formulas and worked examples, kept

Derivations and worked problems land in the examples section instead of being lost in the recording.

ONLINE LEARNING

Course videos, condensed

Turn a recorded module into notes you can skim in minutes, with the structure the video never had.

CORPORATE TRAINING

Training sessions on the record

A recorded workshop becomes a reference document the whole team can search and revisit.

ACCESSIBILITY

Notes when note-taking is hard

Students who cannot write and listen at the same time get complete, structured notes from every class.

SECURITY

Built for sensitive documents

Bank statements, medical files, case records. Security isn't a feature we added - it's the foundation.

lock

Encrypted in transit

Encrypted in transit over TLS 1.2+, and stored in access-controlled, encrypted object storage. Files are protected the moment they leave your browser.

Your files stay yours

Workspaces are isolated per account. Role-based access shows teammates only what they need.

auto_delete

Deleted, not stored

Files are deleted after processing. Everything runs on our own hardware and is never sent to an outside AI service, so your data is never used to train models.
