What people transcribe

One transcript, and every other format from it.

Interviews

Get a quotable transcript with each speaker labelled, so you can find the line you need.

Lectures

Turn a long lecture into searchable text, then study from notes, a quiz or flashcards.

Podcasts

Transcribe an episode for show notes, accessibility, or to repurpose into posts.

Research

Transcribe field recordings and focus groups without paying by the minute for a typist.

How it works

1

Add your recording

Drop in an MP3, WAV, M4A, MP4 or MOV, or paste a link from YouTube, TikTok, a podcast and more.

2

We transcribe it

Speech recognition runs over the audio, labels who is speaking, and timestamps every line.

3

Search, read, export

Read the transcript beside the player, jump to any moment, then export SRT, VTT or plain text.

ONLY WELTO

Anyone can summarize. We put your language on the video.

Translated subtitles

On screen while you watch, or exported as SRT and VTT.

Bilingual synced reader

The original and your language together, in step with playback. Tap any word.

Summary, notes, flashcards, quiz

Table stakes. Welto does these too, in your language.

Questions

What files can I transcribe?

Audio: MP3, WAV, M4A, AAC, FLAC and OGG. Video: MP4, MOV and WebM. You can also paste a link from YouTube, TikTok, Instagram, X, Vimeo and more, and Welto fetches the audio for you.

How accurate is the transcript?

Clear speech transcribes very accurately. Strong accents, crosstalk and background noise are harder, as they are for any system, so the transcript stays editable and every line links back to its moment in the audio.

Which languages does it handle?

Over 50, and the language is detected automatically. You can translate the finished transcript into any of them afterwards, keeping the original timings.

Is it free?

The free plan includes 3 videos a day and 3 file uploads a month, up to 20 minutes each. Pro adds longer recordings, bigger files and unlimited uploads.
