So the channel hit 100k subs in eight months — what actually moved the needle?
Honestly, posting Shorts daily for six weeks. The long-form watch time followed.
And the thumbnail rework — was that A/B tested in YouTube Studio?
Yeah, the new Test & Compare tool. Two of three winners had no face on them.
↓ This is the dashboard
Same layout as the real dashboard — Summary, full Transcript, Speakers tab, Exports. Key points and action items extracted automatically. Auto-tags on every job.
Sample preview from a founder interview about post-call workflow. Real transcripts look exactly like this — same tabs, same summary block, same key-points / action-items split, same auto-tag chips.
Three real options · honest comparison
YouTube ships auto-captions on every video for free — they're just not very accurate and have no speaker labels. Rev sells human-typed transcripts at $1.50/min. We sit in the middle: AI at 95%+, speaker labels, three-minute turnaround.
Free, baked into every public video. No punctuation pass, no speaker labels.
Paste the URL. Three minutes later: clean transcript, SRT/VTT, AI summary with chapter links.
A human types it. Highest accuracy, slowest turnaround, priced per minute.
Pricing accurate as of 2026. Rev rates reflect their standard service tier; AI-only tiers from competitors not compared here.
Specific to YouTube
YouTube audio has quirks that off-the-shelf transcribers don't handle. Flip the right settings and the transcript comes back ready to re-upload as captions.
Paste a YouTube URL and these flip on by default. Override per-job from the form.
Accuracy · real-world numbers
YouTube content varies wildly — a studio podcast and a Fortnite stream are not the same problem. Lapel-mic talking-head is the best case; background music and overlapping game audio drag accuracy fastest. Numbers below are from real customer YouTube URLs in production.
Joe Rogan-style setup: each guest on a separate boom mic, light room treatment, no music bed. Diarization is trivial when voices don't bleed.
Standard tutorial or video essay. One speaker, indoor audio, intro music ducked under voice. Most YouTube uploads land here.
Wind, traffic, ambient music under voiceover. Words still usable; expect occasional misses on proper nouns and brand names.
Game SFX, music, and chat-reading at variable volume. Streamer's voice usually clear; teammates on Discord drop fastest. Worst case in our data.
