Use tool ↗About Checksub
Checksub automates subtitles, translation, and dubbing for video, claiming coverage of roughly 200 languages with AI dubbing, voice cloning, and voice isolation. An editor lets you fix transcripts and subtitle styling after generation, including karaoke-style animated captions, and a script-conversion feature re-syncs an edited script back to the original video timing. The France-based company was founded solo in 2017 by Florian Stegre, who built it after struggling to create subtitles manually for an earlier video project, and it says it has processed over 150,000 videos for more than 500 companies. Plans are billed in hours of video credits per month rather than per video or per minute.

Pros & cons of Checksub
Checksub covers the full pipeline from subtitles to full AI dubbing with voice cloning, which saves stitching together separate transcription and dubbing tools. The credit-per-hour pricing is straightforward to reason about compared to per-minute billing elsewhere, though the entry Junior tier's 2 hours a month will not stretch far for a channel publishing regularly. It is a mid-size, France-based vendor rather than a large platform, which shows in the tier structure jumping from $59 straight to a $299 Enterprise plan.
Pros
- Subtitles, translation, and AI dubbing with voice cloning in one workflow
- Editable transcripts and post-generation subtitle styling, including animated captions
- Direct YouTube channel connection for publishing
- Free trial credits to test the pipeline before paying
Cons
- Entry Junior tier's monthly credit allowance is small for regular publishers
- Large price jump between the Starter and Enterprise tiers
- AI-dubbed voices will not match professional human dubbing quality in nuance
Best for
- Creators and small teams localizing video into multiple languages
- YouTube channels wanting subtitles plus optional AI dubbing in one tool
Not for
- High-volume publishers needing more than a few hours of monthly credits without jumping to the Enterprise tier
- Teams wanting broadcast-grade human dubbing rather than AI voices
Watch out: Credits are consumed by video duration across subtitling, translation, and dubbing combined, so using multiple services on the same video draws down the monthly allowance faster than expected.
