Our verdict on Checksub
Checksub is a web-based video localization platform for creators, businesses, media teams, and organizations. It combines automatic subtitle generation, translation, AI dubbing, voice cloning, script-to-subtitle conversion, and speaker detection. Teams can edit subtitle timing and text, customize styles and animations, export burned-in videos, or download SRT and VTT files. Its feature set suits small teams that need more than caption generation, particularly when dubbing and branded subtitle presentation are part of the workflow.
Pricing is organized around credits and access to localization features. According to the published plans, Junior costs $18 per user per month when billed monthly, or $12 per user per month when billed annually. The monthly plan includes 2 hours of credits, while the annual plan includes 24 hours of credits per year; both include one translation per project, SRT and VTT export, 20GB of storage, and a 4GB upload limit. Starter costs $59 per user per month monthly, or $48 per user per month annually, with 5 hours of monthly credits or 60 hours of annual credits. It adds no-watermark exports, AI dubbing, lip-sync beta, voice cloning, and one YouTube channel connection.
The standout breadth is the combination of caption production and video localization in one product. Subtitle styling, speaker ID editing, burn-in export, translation, dubbing, and voice cloning cover several stages of multilingual video preparation. Enterprise adds custom credits, translation in 187 languages, API access, YouTube channel connections, and an account manager, making it the clearest fit for organizations with custom workflows. Checksub is a sensible choice for teams prioritizing subtitles and dubbing, but teams seeking a wider integration ecosystem should look elsewhere because YouTube is the listed integration.
