Under the hood

Built on the best AI stack

We use production-grade AI tools so you get accuracy without the wait.

OpenAI Whisper is our primary transcription engine. It runs locally, handles accents, technical vocabulary, and background noise better than any cloud alternative — and it's free, keeping our prices low.

  • Handles 50+ languages automatically
  • Strong accuracy on accented speech
  • Processes audio 10x faster than real-time
  • No audio ever stored on third-party servers
# Jack5 captioning pipeline import whisper model = whisper.load_model("large-v3") result = model.transcribe( "client_audio.mp3", language="en", word_timestamps=True ) # Export to SRT format export_srt(result, "output.srt")

Descript gives us a visual editor where we can clean up transcripts like a text document — fixing errors, removing filler words, and styling captions before export.

  • Edit captions as plain text
  • Remove filler words automatically
  • Export to SRT, VTT, or burned-in video
  • Speaker labeling and separation
// Descript export workflow const project = await descript.open({ file: "transcript.json" }); await project.removeFiller(); await project.export("srt");

Make.com connects all our tools automatically — when a client submits a file, it triggers transcription, QC alerts, invoicing, and delivery with zero manual steps.

  • Automatic file intake via Google Drive
  • Triggers transcription pipeline on upload
  • Sends invoice on delivery automatically
  • Slack/email alerts at each stage
# Make.com scenario Trigger: New file in Google Drive ↓ Action: Run Whisper pipeline ↓ Action: QC + deliver to client ↓ Action: Send invoice via Stripe

Questions answered

Frequently asked questions

If something's not covered here, just ask the chat in the corner.

How accurate is the transcription? ▼
We average 98–99% accuracy on clear audio. For challenging recordings (heavy accents, crosstalk, low-quality audio), accuracy can dip to 95–97%. Every transcript is reviewed by a human before delivery. A free revision is included if anything feels off.
What audio/video formats do you accept? ▼
Basically everything: MP3, MP4, MOV, WAV, M4A, AAC, FLAC, AVI, MKV, and more. For very large files (over 2GB), we'll give you a Dropbox or Drive upload link.
How does the 24-hour turnaround work? ▼
The clock starts when we receive your confirmed, paid order. Most files under 60 minutes are delivered well within 24 hours — often same day. Rush (same-day) slots are available for an additional fee.
Is my audio/video kept confidential? ▼
Yes. Your files are processed using Whisper AI running locally — your audio never touches OpenAI's servers or any third-party cloud. Files are deleted within 30 days of delivery. We can provide an NDA for sensitive content on request.
What's the difference between SRT and burned-in captions? ▼
SRT/VTT is a separate file you upload alongside your video — viewers can toggle it on/off. Burned-in captions are permanently embedded into the video, ideal for social media clips or platforms that don't support separate caption files.
Do you handle multiple speakers? ▼
Yes — speaker diarization is included at no extra charge. We'll label speakers by name if you provide a list. Interviews, panels, and roundtables with up to 6 speakers are no problem.
Can you transcribe in languages other than English? ▼
Yes — Whisper AI supports 57 languages including Spanish, French, Portuguese, German, Japanese, Mandarin, Arabic, and more. Just let us know the language when you submit.
What's included in the monthly retainer? ▼
Retainer plans start at $200/month and include up to 3 hours of audio/video, priority turnaround, dedicated handling, and discounted rates on add-ons. Custom plans available — just ask via chat.
