Audio to notes FAQ
Quick answers on files, limits and downloading your notes.
How do I turn audio into notes?
Drop your audio file into the box at the top of this page, or browse for it. The audio to notes tool starts at once and gives you short notes with the key points.
Is the audio to notes tool free?
Yes, for files of up to 10 minutes and 25 MB, with no account. There is a limit per visitor, shared across the free tools. If you reach it, the page tells you how long to wait.
Do I need an account?
No. You can upload a file, then copy or download the notes without signing up. You need a free account to ask about the audio, make flashcards or save it to your library.
Which audio files can I upload?
MP3, M4A, WAV, OGG and WebM. Gistr checks the file itself, so renaming a file does not change its type.
How long can my audio be?
Up to 10 minutes. Over that, the page offers a free account. A free account takes files of up to 10 MB, so a long recording may need compressing or a paid plan.
Why is my WAV file too large?
The file cap is 25 MB, and CD-quality WAV reaches it in about 2.4 minutes. Save the recording as MP3 or M4A. Ten minutes of MP3 fits under the cap.
What do the notes include?
The key points from the recording, written as short lines that are quick to revise from. The notes come from an AI transcript, so names and technical terms can come out wrong.
Can I download the notes?
Yes. Copy them in one click, or download them as a TXT or Markdown file to revise offline.
Can I get the full transcript instead?
Yes. The audio to text tool gives you every line with timestamps.
What happens to my audio file?
Gistr holds the file in memory during the run and does not save the file itself. The audio goes to a third-party transcription provider, and a third-party AI model writes the notes. Those providers’ own data policies apply. Gistr keeps the notes for up to 30 days, matched to a fingerprint of the file, so the same file gets the same result faster.
What is Gistr?
Gistr is an AI knowledge companion that turns YouTube videos, podcasts, articles and PDFs into knowledge you keep. Ask questions and get answers that cite the exact source, make notes, slides and flashcards, and keep everything in one searchable library.
