How it works
Add your recording
Drop in an MP3, WAV, M4A, MP4 or MOV, or paste a link from YouTube, TikTok, a podcast and more.
We transcribe it
Speech recognition runs over the audio, labels who is speaking, and timestamps every line.
Search, read, export
Read the transcript beside the player, jump to any moment, then export SRT, VTT or plain text.
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
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.
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.
Over 50, and the language is detected automatically. You can translate the finished transcript into any of them afterwards, keeping the original timings.
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.
