CaptionX Discount Code (2026) — 20% off on the first payment
CaptionX is an AI captioning tool built around an Adobe Premiere Pro plugin (installed free from Adobe Exchange, for Premiere Pro v24+) that auto-transcribes speech and drops styled, animated captions straight onto the timeline, so editors don't have to round-trip through a separate captioning app. For people who don't use Premiere, it also offers a browser-based 'Web Caption Studio' for uploading a video, auto-captioning it, and exporting an MP4 or subtitle file. Beyond core captions it bundles an AI Silence Remover, a Profanity Filter, AI Eye Contact Correction, and an AI Clip Generator that turns long videos or podcasts into short vertical/square clips with captions burned in. The company behind it is Tether Technologies Pty Ltd, whose own site (tethertechnologies.com.au) lists CaptionX as one of its products.

At a glance
Our take on CaptionX
CaptionX is a fairly focused product: an Adobe Premiere Pro auto-captioning plugin with a browser-based companion tool for people editing elsewhere, plus a few genuinely useful extras (silence removal, profanity filtering, AI eye-contact correction, and short-clip generation). For editors who already live inside Premiere Pro, having captions generated and styled on the timeline without exporting to a separate app is the main selling point, and it's a real one.
Public information about the company beyond its own site is thin — it's run by Tether Technologies Pty Ltd, an independent review site rated it 4/5 with the caveat that automatic captions still need manual review on messy audio, and its Capterra listing currently shows no user reviews and pricing numbers that don't match CaptionX's own current pricing page. That inconsistency, plus limited independent scale/founding details, means we'd treat marketed claims (like specific user counts or ratings) with some caution until you've tried the free tier yourself.
Pros & cons
- Captions generate and style directly on the Premiere Pro timeline, no separate app or file round-trip needed
- Free tier with no credit card required, so you can test caption quality before paying
- Supports 100+ languages including right-to-left scripts, with unlimited translation on paid plans
- Useful bundled extras: silence remover, profanity filter, AI eye-contact correction, AI clip generator for shorts
- Also works outside Premiere Pro via the browser-based Web Caption Studio
- Its most complete feature set (Clip Generator, unlimited transcription, watermark removal) is really built around the Premiere Pro plugin, so non-Premiere users get a lighter experience
- Like most auto-captioning tools, accuracy drops with overlapping speakers, noisy audio, or heavy accents and needs manual cleanup
- Pricing has appeared inconsistent across sources (its own site vs. third-party listings), so double-check the live price before subscribing
- Very little independent, verifiable information about company scale or track record beyond its own marketing
Who CaptionX is for
Video editors who work inside Adobe Premiere Pro and want captions, silence removal, and short-clip creation handled without leaving their timeline.

Frequently asked questions
What does CaptionX actually do?
It's an AI captioning tool, mainly used as an Adobe Premiere Pro plugin that auto-transcribes your audio and adds styled, animated captions directly on the timeline. It also has a browser-based Web Caption Studio for captioning videos outside Premiere, plus extras like a silence remover, profanity filter, AI eye-contact correction, and an AI clip generator for turning long videos into short captioned clips.
Do I need Adobe Premiere Pro to use CaptionX?
No. Premiere Pro integration is its main workflow, but CaptionX also offers a browser-based Web Caption Studio where you can upload a video and export a captioned MP4 or subtitle file without any editing software installed.
