Sound familiar?

You know the pain.
We built the cure.

If you edit video in a language Adobe ignores, every project starts with the same dread.

Typing every subtitle by hand

3 to 5 hours of manual subtitling for every hour of footage. Time you'll never get back.

"Your language isn't supported"

Adobe's Speech-to-Text works great — if you speak one of 16 languages. Yours isn't one of them.

// thanks, Adobe

Another monthly subscription

Creative Cloud. Spotify. Netflix. ChatGPT. Every tool wants $15/month — forever.

Uploading client footage to who-knows-where

Cloud tools send your confidential footage to servers you don't control. NDA? What NDA?

// privacy nightmare

Why CaptionLab

Four reasons it just feels right

Buy once

No subscription. Ever.

Pay $39 one time. Use it forever. No monthly invoice, no "your plan expired" message at 2am before a deadline. You own it.

Your machine

100% offline. No API keys.

No Deepgram account. No Groq key. No OpenAI credits. Whisper runs locally on your Mac. Your footage never touches the internet.

Your language

99 languages. Including yours.

The Eastern European, Middle Eastern, and Asian languages Adobe never supported. If Whisper speaks it, CaptionLab subtitles it.

Your timeline

Native Premiere integration.

Subtitles appear as a real, editable Premiere caption track — not a screenshot, not an export. Edit timing and text like always.

Questions

Before you ask

Do I need an internet connection?
Only once — to download the Whisper model during setup (~1.5 GB). After that, CaptionLab runs 100% offline. No internet, no servers, no nothing.
Do I need an API key or an OpenAI account?
No. Unlike cloud tools, CaptionLab runs the Whisper model locally on your Mac. No Deepgram, no Groq, no OpenAI credits. Nothing to sign up for.
Is my footage uploaded anywhere?
Never. Every byte of audio is processed on your own machine. Perfect for client work under NDA.
Which Premiere Pro versions are supported?
Premiere Pro 2023 through 2026 (versions 23.x–26.x). Works on Apple Silicon (M1–M4) and Intel Macs.
Is there a Windows version?
In active development. Right now CaptionLab is Mac-only. Join the list and you'll be first to know when Windows drops.
What languages are supported?
All 99 languages Whisper supports — including Ukrainian, Polish, Turkish, Indonesian, Vietnamese, Arabic, Thai, Romanian, Czech, Slovak, Hungarian, Greek, Hebrew, Persian, Urdu, and dozens more.
