Frequently asked questions

Short answers to the questions people ask before their first transcript. Each one points to the page that carries the full answer.

Do I need an account?

Not for a single video. Without signing in you can extract the caption track from one video at a time and take the text as a plain TXT file. Everything else — AI transcription, playlists, uploads, the other six export formats, and the library that keeps your transcripts — needs a free account. See Get your first transcript.

What does it cost?

Caption extraction is free, on any video, of any length. AI transcription, summaries and RAG JSON are paid for with prepaid credits, and credits never expire. New accounts start with a balance to try it. See Credits for the rates and Pricing for the packages.

What's the difference between captions and AI transcription?

Captions are the subtitle track a video already carries, usually generated by YouTube. AI transcription reads the audio and writes the transcript from scratch, returning punctuation and complete sentences. The choice sets the quality of everything you export afterwards. See How INDXR works.

What formats can I export?

Seven: TXT, Markdown, CSV, SRT, VTT, JSON and RAG JSON. TXT and Markdown each come with and without timestamps, which makes nine downloads in total. Only RAG JSON costs credits, and re-downloading anything you already generated is free. See Export formats.

Which languages does INDXR handle?

Caption extraction works in whatever language the video's track is in, and INDXR anchors on the original-language track rather than a translation. AI transcription covers a wide range of languages, and how well it performs differs per language. See Accuracy and languages.

What if a video has no captions?

INDXR does not check in advance whether a video carries a caption track. If the attempt comes back empty, INDXR says so and offers to transcribe the audio instead. In a playlist, videos without captions are skipped while the job runs and the credits held for them are returned. See Single video.

Can I transcribe a whole playlist at once?

Yes. INDXR lists the videos it can reach and you choose per video whether to take the captions or transcribe the audio. The job keeps running after you close the tab, and finished transcripts appear in your library as they complete. See Playlists.

Can I upload my own audio or video files?

Yes. An uploaded file has no caption track to fall back on, so uploads are always transcribed. There are limits on file size and length. See Uploads and Limits.

What happens to my files?

Audio is deleted as soon as the transcription finishes; INDXR keeps no recording of it. The transcript itself stays in your library until you delete it. See Privacy.

Is there an API?

No. INDXR is a web application; there is no public REST API. See Limits.

What is INDXR.AI?

INDXR turns a YouTube video — or a whole playlist, or an audio or video file you upload — into text, either by copying the captions the video already carries or by transcribing the audio. From there you read it, edit it, and export it as plain text, subtitles, CSV, Markdown or JSON. See How INDXR works.

Do I need a browser extension?

No. INDXR runs entirely in the browser — there is nothing to install, no extension or plugin. Open the site, paste a URL, and extract. See Get your first transcript.

How do I get a transcript as a plain text file?

Paste the video URL, extract, and export as TXT — plain text is the one format you can download without an account. See Get your first transcript for the full flow and Export formats for what each file contains.

How long does transcription take?

Caption extraction is effectively instant — there is no audio to process. AI transcription runs at a fraction of the video's length: an hour of audio is usually done in a couple of minutes, and the app shows an estimate before you confirm.

Can I use the transcripts commercially?

The transcripts you create are yours to use, including for commercial work. INDXR doesn't own or control the videos you transcribe, so the underlying content still belongs to its creator. See our Terms.
