Checksub - 2026 Pricing, Features, Reviews & Alternatives

Checksub is a cloud-based web application that automates video subtitling, translation, and dubbing for businesses, content creators, media groups, TV channels, tech startups, and enterprise organizations with high-volume localization needs. The platform performs automatic speech recognition to generate subtitles from audio or uploaded scripts, translates content into 200 languages, and produces AI-dubbed audio tracks with voice cloning that replicates original speaker intonation and prosody in 80+ languages. Lip-sync generation, speaker diarization, and background audio preservation are included in the dubbing workflow. An online editor allows post-generation review and fine-tuning of text, timing, synchronization, and prosody at the individual sentence level, with AI correction guidelines configurable per project.

Subtitle output supports multiple export formats including SRT, VTT, TXT, and ITT, as well as direct video export with burned-in subtitles. Style and animation customization covers fonts, colors, karaoke animation, and pre-built templates. Term bases enforce consistent terminology and pronunciation across projects. A YouTube publishing integration supports direct distribution. For teams and enterprise accounts, Checksub provides user management, collaboration tools, and an external API with project management and export capabilities, making it suited for e-learning, training video localization, and large-scale content distribution workflows. Tiered subscription plans scale from individual professionals to enterprise-level volume, with a free trial covering one hour of video translation.
