How do I import a recording?

Choose up to 10 audio or video files saved on your device, or drop it into the tool. Check its name and duration, select the spoken language, then press Start transcription.

On iPhone, use Share in Voice Memos to save the recording to Files or transfer it to your computer. On Android, use Share or Export in your recorder app. Choose the actual audio file, not a cloud sharing link or a recorder project.

If a recording is only a cloud placeholder, download it first. A laptop or desktop is recommended for longer recordings and larger models.

Which files can I use?

Audio: MP3, M4A (AAC), WAV, FLAC, OGG, Opus, AAC and M4B. Video: MP4, MOV, WebM, MKV and TS; only the audio track is used. Local files have no product size or duration cap. Files are read and decoded in sections. Codec support, memory and speed depend on your browser and device.

Not supported: Apple Lossless (ALAC) M4A, AIFF, WMA, AMR voice recordings (.amr or .3gp), AVI, ADPCM WAV, and videos with Dolby (AC-3 or E-AC-3) audio. Convert these to MP3 or WAV first; renaming a file does not convert its audio. An unsupported file is reported as soon as you add it.

YouTube links and Notion

Paste a public YouTube link on the homepage or the YouTube transcript page. Original captions are free without an account. A video without captions can be transcribed on your device after signing in, up to five per day; the audio is fetched once by a service hosted on Cloudflare and is not kept. Saving to Notion requires signing in and authorizing your workspace. Cloud transcription is not open yet.

TXT, SRT, Markdown and ZIP downloads include the full available text, even for long recordings. Cancelled or failed recordings can export their partial text. Use Save to Notion beside Export to prepare a local text draft and continue in a new tab. Your recording stays open; login and Notion connection happen in My library. Notion saves currently accept up to 60 minutes, 10,000 segments and 1 MB of text per recording.

MP3

A supported MP3 can be selected directly, including recordings longer than 60 minutes. Keep this page open while processing.

M4A

Most M4A files contain AAC audio and work. iPhone Voice Memos recorded with Audio Quality set to Lossless use Apple Lossless, which Chrome and Edge cannot decode: choose Compressed for new recordings, or convert existing ones to AAC M4A or WAV.

WAV and damaged files

WAV works with 8-, 16-, 24- and 32-bit PCM, 32-bit float, µ-law and A-law audio, decoded in sections. If a file fails, check that it plays in your recorder, export it again, or try a shorter recording on a computer.

Why does a model download? Where does my audio go?

Speech recognition runs on your device. Selected files and your transcript stay in the current page; the original file is unchanged. The browser downloads model and runtime files, and the site sends anonymous usage events without audio, filenames or transcript text.

Fast and Balanced are intended for English. Selecting another language switches to Best. Open Quality before starting to review quality and approximate model download sizes. Larger models need more memory; preparation takes time even after downloading.

Speaker labels are also found on your device. If you know how many people speak, set Speakers in Settings; choose One speaker to skip this step. After transcription you can rename speakers, or give two the same name to merge them.

The browser may reuse cached models, but caches can be cleared or evicted. Keep the tab open while it works. For download errors, check your connection and retry. For memory problems, try a shorter file on a computer.

The full transcript is free, with no signup or commercial minutes quota. Format and device limits still apply. Refreshing clears the local audio queue. Saving to Notion is optional and requires signing in; its existing transfer limits are separate from local transcription.

How do I check, edit and save the text?

Search for a phrase and choose Next to move through matching segments. Long transcripts are shown in pages of up to 100 segments. Search covers the entire transcript and opens the matching page. Click a timestamp to listen back. Choose Edit to correct the text, then Done editing. Timestamps cannot be edited.

For lectures, check names and technical terms against the recording. For podcasts, verify wording and timing before using a subtitle export. Speaker labels are not automatically identified. Chapters and extracted key points are optional navigation aids and update when you edit the text.

Copy takes the complete edited text. Export offers TXT for plain text, SRT for subtitles and Markdown for text with timestamps and chapters.

You can cancel during file checks, model preparation or recognition. Completed sections remain a partial transcript that you can edit and export. Retrying starts from the beginning; export anything you want to keep before replacing a result.

Copy or export before refreshing, leaving or closing the page. Files, text and edits only live in page memory and are not saved automatically.
