YouTube transcription. Better than auto-captions.
Cheaper than human.

YouTube's built-in auto-captions stop at 80% accuracy and don't separate speakers. Human transcribers cost $1–3 per minute and take overnight. Our pipeline lands at 95% on production-quality YouTube, separates speakers on Pro, and finishes in roughly 6× realtime — for $0.03 per minute.

What auto-captions miss

Of words YouTube's built-in auto-captions get wrong on production-quality video. Plus 100% of speaker labels, chapter markers, and citation timestamps — those don't exist in auto-captions at all.

YouTube auto-captions vs. AI service vs. human transcriber

Pick the column that matches what you need. Most teams use AI for the 95% case and a human for the 5% legal/medical edges. Auto-captions are useful as a fallback when there's literally no budget.

BeliefsWhat people assume vs what's actually so

Three things people get wrong about YouTube transcription

These are the assumptions we hear weekly from teams who've never tried it. Each is a real misconception that costs hours.

YouTube's auto-captions are fine for everything except formal stuff.
Auto-captions miss roughly 1 word in 5 on production-quality video, omit speaker turns entirely, and drift on timestamps. Fine for letting a viewer turn captions on; not fine for blog posts, citation, or social-clip captioning.
I have to download the video first, then transcribe it locally.
Paste the URL — we handle the resolution and audio extraction server-side. No local download, no ffmpeg dance, no Python venv. Free /tools/youtube-downloader path exists if you actually want the file, but transcription doesn't need it.
API costs more than the dashboard, so I'll just paste URLs by hand.
Same backend, same pricing. The API costs nothing extra. It exists for batch jobs (back-catalogue archives, weekly automation, multi-channel monitoring) where pasting one URL at a time would be insane.

What you can do with the transcript

01

Re-upload captions to YouTube

Export the SRT and upload it via YouTube Studio → Subtitles. Useful for older videos with auto-captions you don't trust, or for languages YouTube doesn't auto-caption.

02

Convert to a blog post

AI summary + transcript + timestamps gives you the raw material for a long-form post. Most users edit the summary outline, paste in the most-quotable transcript blocks, and ship in 30 minutes.

03

Pull key quotes for social

Find the moment where the speaker says something quotable, take the transcript snippet plus the timestamp, and you have a LinkedIn or X post linked to the exact YouTube moment.

04

Search across hours of video

If you keep a library of research interviews, conference talks, or competitor podcasts, search hits the words inside, not just titles. Click a result and the transcript opens at that moment.

05

Multi-speaker labelling

Podcast on YouTube? Conference panel? Pro and Business plans separate two or more voices. Manual rename per speaker — handy when there's a guest you want to credit.

06

API for batch ingestion

POST a list of YouTube URLs, GET transcripts back via webhook. Useful if you're archiving a creator's full back-catalogue or running competitive analysis. Per-key rate limits, JWT auth.

5.0 / What worksYouTube content types we transcribe well

Types of YouTube videos that work

Anything where the speech is the centre of the audio works. Music videos, ASMR, and silent gameplay won't produce useful transcripts — the words just aren't there. Below: the categories where users actually use this.

CoverageTop-tier languages on YouTube

Languages we transcribe at studio quality

Tier 1 — the languages where you get 95%+ accuracy on production-quality YouTube without an editorial pass. We support 99 total; the 8 below are the ones that matter for the bulk of English-, Spanish-, and European-language YouTube.

Worked exampleFrom the inbox of a working tech reviewer

How one channel back-captioned a 4-year archive

A solo tech-review YouTube channel — 168 videos over 4 years, average 22 minutes each. The creator wanted real captions on the older videos (not auto-captions), plus searchable transcripts to convert top-performing videos into SEO blog posts. Total runtime to caption: 61.6 hours of video.
01

Bulk-uploaded URLs via the API

POSTed all 168 youtube.com URLs in a CSV to the /jobs endpoint, one webhook to receive completion. Pasted the API key, watched the queue.

QualityWhat to expect, honestly

Accuracy on YouTube audio specifically

YouTube audio quality varies more than any other source — a Vox-style production playing back at studio quality, a vlog filmed on a windy beach with a phone, and a Zoom-recording-uploaded-as-a-video are all called "a YouTube video". Here's what to expect.

95%+
On videos with clear speech, decent mic, single or two speakers. This is the typical podcast-on-YouTube, tutorial, conference talk, news clip — the long tail that actually gets transcribed.
What we deliver
95%+

Production-quality YouTube.

USB or shotgun mic, indoor or controlled outdoor, one to two speakers. The result you get on most channels you'd actually want to transcribe.

  • Tutorial channels with a podcast-style mic setup
  • Conference talks captured by venue PA
  • Interview podcasts on YouTube (e.g. solo + guest)
  • News and explainer videos with voice-over
What's normal
85%+

Phone-recorded YouTube.

Vlog filmed on a phone, multiple speakers in a panel, light music bed, occasional background noise. Most words right; an editorial pass catches the rest.

  • Phone-recorded vlogs
  • Multi-host livestream replays
  • Outdoor street interviews
  • Mobile-recorded conference panels
What blocks YouTube transcription

Private and members-only

Anything that requires a YouTube login — private videos, channel-members content, age-gated videos — won't resolve through our URL pipeline. If you have authorisation, download the file via YouTube Studio and upload it directly to us instead.

Live streams

Active live streams aren't supported. Wait for the stream to end and YouTube to publish the VOD. Then paste the VOD URL.

YouTube anti-bot challenges

YouTube occasionally blocks server-side fetches as a bot. If we hit this, the dashboard tells you exactly so — download the audio yourself via the /tools/youtube-downloader path and upload the file. We're working on a more reliable URL fallback.

Music-heavy content

Music videos, lyric videos, ASMR, and silent gameplay won't produce useful transcripts. The words aren't there.

ReferenceCommon questions

Frequently asked questions

  1. 01Which YouTube URLs work?
    Public videos at youtube.com/watch?v=…, youtu.be/…, music.youtube.com, and m.youtube.com. Both desktop and mobile URLs resolve. Private, members-only, age-restricted, and live-streaming videos won't resolve through the URL pipeline. Playlist URLs need to be split — paste the individual video URL.
  2. 02Does it transcribe long videos like 4-hour podcasts?
    Yes. The Business plan accepts up to 4 hours per file. Long videos split into chunks server-side and process in parallel — a 4-hour talk typically completes in 35 minutes. Pro caps at 60 minutes per file; Free at 30 minutes.
  3. 03How accurate is the transcript on YouTube content?
    95%+ on production-quality YouTube — tutorials, podcasts on YouTube, conference talks, news clips. ~85% on phone-recorded vlogs, multi-speaker panels with crosstalk, or videos with a strong music bed. We recommend a single editorial pass for anything you'll publish without watching back.
  4. 04Are speaker labels included?
    Yes, on Pro ($19/month) and Business ($49/month) plans. Two or more voices are separated and labelled. Quality depends on audio: clearly recorded interviews work best; three speakers talking over each other is harder.
  5. 05Can I get an SRT file to re-upload as captions?
    Yes. Export SRT (and VTT) directly from the transcript page. Upload to YouTube Studio → Subtitles → Add → Upload file. Useful for older videos with bad auto-captions or for languages YouTube doesn't auto-caption well.
  6. 06Does it work for non-English YouTube videos?
    Yes — 99 languages auto-detected. Studio-grade quality on tier-1 (English, Spanish, German, French, Portuguese, Italian, Dutch, Polish), production-grade on tier-2 (Russian, Japanese, Mandarin, Korean, Indonesian, Swedish, Norwegian, Danish, Finnish, Czech, Ukrainian, Greek, Turkish), usable on tier-3 (Arabic, Hebrew, Hindi, Vietnamese, Thai, Romanian, Hungarian).
  7. 07Do I need a YouTube Premium account?
    No. We don't use your YouTube account at all. Public videos resolve through their public URLs. The /tools/youtube-downloader path is a free utility you can use without an account; the transcription pipeline does require a free account to save your transcripts.
  8. 08What happens if YouTube blocks the request?
    Sometimes YouTube's anti-bot system flags server-side fetches. If we hit it, the dashboard tells you with a clear message — download the video file yourself (e.g. via /tools/youtube-downloader or YouTube Studio if it's your video) and upload the file to us. Same accuracy, no URL-blocking risk.
