Checksub · Voice & Language · Video
Checksub Com is an online platform that builds subtitles, translations and AI dubbing for video. It works as an AI subtitle generator first, then doubles as a video translation and dubbing tool. It auto-writes subtitles, translates them into 200 languages, and dubs the result with voice cloning that keeps the original background audio intact. Teams use it to localize training videos, grow YouTube channels, and publish the same clip to audiences that speak different languages.
About Checksub Com
What Is Checksub Com
Checksub Com is a web-based subtitle and dubbing service aimed at creators and companies that publish video in more than one language. The pitch is simple: upload a video, let the AI write the subtitles, then translate or dub it without hiring a separate voice cast for each market. The company says it spent six years building the automatic subtitling engine, and the site now claims more than 500 businesses as customers.
The part that separates it from plain caption tools is dubbing. Checksub keeps the music and background noise from your original clip and swaps only the spoken voice, which is why a dubbed video still sounds like it was recorded in the same room. Why does that matter? Because most dubbed clips sound flat and detached, and that's exactly the tell that turns viewers off. Voice cloning extends that further. You record a sample once, and the platform reads your translated lines in a voice that sounds like yours across 30 languages.
The catch is scope and cost. Subtitling and translation run automatically, but complex languages and dense jargon still need a human pass. The editor exists for that. Pricing starts at $18 a month. The heavy lifting (unlimited upload sizes, custom plans, API access) sits behind the Enterprise tier. If you only need captions once in a while, the entry plan's single translation per project will feel tight.
Getting Started
- Create an account at checksub.com and pick a plan, or start with the free trial to test the engine on a real clip.
- Upload your video or paste a script. Uploads run up to 4 GB on the standard plans.
- Let the AI generate the subtitles, then open the editor to fix any lines and style the look.
- Pick a target language for translation or dubbing, and choose whether to clone your voice.
- Export the subtitle file (SRT, VTT and others) or burn the styled subtitles into the video.

Key features
Automatic Subtitles
The platform transcribes speech and times the captions for you, so you skip the manual typing stage. The company leans on the accuracy of its engine to cut down on proofreading, and the built-in editor is there for the lines that still need a fix. It's the fastest part of the workflow. Most creators notice it first.
Translation in 200 Languages
Once the subtitles exist, Checksub translates them into roughly 200 languages. The workflow is built around subtitling specifically, which matters because translation tools not designed for captions often break timing or split sentences badly. You get a translated subtitle file you can still edit line by line.
AI Dubbing With Voice Isolation
This is the feature that sets Checksub apart from a basic caption tool. It separates the original voice from music and background noise, then replaces only the speech, so the dubbed version keeps the same audio atmosphere as the source. A translated video doesn't sound like it was rebuilt from scratch in a studio.
Voice Cloning
You record a sample, and the platform reads your translated lines in a voice modeled on yours. The company puts support at 30 languages. For creators who appear on camera, that keeps a consistent voice across markets without re-recording every version. One click swaps your original voice-over for the clone.
Styled and Animated Subtitles
Checksub offers dozens of style and animation settings, including one-click karaoke animation and pre-built templates. You can burn the styled subtitles into the video, or export a separate subtitle file if you'd rather keep the footage clean. Social teams lean on this for captions that match a brand look.
Online Editor
After the AI finishes, everything is editable. You can rewrite a single sentence and regenerate it, adjust timing, and restyle lines without touching the rest of the project. That matters a lot. Names, technical terms and jokes break machine translation most often, even when the rest of the text is clean.
Script to Subtitles
If you already have a script, Checksub converts it into subtitles synced to your video. This skips transcription errors entirely. That's handy for scripted content like courses and product demos, where you know the exact wording in advance.
YouTube Channel Connection
You can link a YouTube channel and manage the publishing of localized versions from inside the platform. It's aimed at creators running several language-specific channels off one piece of content. It saves the manual re-upload step across each one.
Pros and cons
Pros
- Dubbing keeps original music and background audio, so translated videos sound natural instead of rebuilt.
- Translation covers around 200 languages, which is more reach than most caption tools offer.
- Voice cloning works across 30 languages, letting creators keep one consistent voice per market.
- The editor handles per-line regeneration, so you can fix names and jargon without redoing the whole project.
- SRT and VTT export plus burn-in give flexibility for different publishing needs.
Cons
- No free plan. You get a free trial, but ongoing use starts at $18 a month.
- The entry plan allows only one translation per project, so multi-language work quickly pushes you to the Starter tier at $59 a month.
- Dubbing, voice cloning and API access sit on the Starter and Enterprise plans, which raises the real cost for anyone who needs them.
- Machine translation still needs a human check for technical or idiomatic content, adding a review step.
