Checksub — AI-assisted subtitling and dubbing service
Checksub is a web-based platform that uses artificial intelligence to create subtitles and localize videos into more than 200 languages. It is offered as a subscription service and is aimed at both solo creators and organizations that want to make their video content more accessible and reach wider audiences.
Core capabilities
- Fully localized dubbing with voice-cloning to preserve original tone and character.
- Fast generation of clean, production-ready subtitles tailored to your script timing.
- Support for translations into 200+ languages to expand global reach.
- Customizable subtitle appearance and motion effects so captions match your brand.
Export and file options
Users can export videos with subtitles permanently embedded, or download separate subtitle files (SRT, VTT, etc.) for flexible use. The platform also converts written scripts into time-aligned subtitles ready for publishing.
Editing and quality control
An online editor lets you review and refine both automatically generated captions and dubbed audio, improving timing, accuracy, and clarity before final export. This makes it easy to correct any machine-generated errors and polish the final output.
Who benefits most
- Individual creators who want to add subtitles or dubbed tracks to increase engagement.
- Businesses and training teams needing to translate course or internal videos for distributed teams.
- Media teams optimizing content for platforms like YouTube and other social channels.
