Checksub: AI Subtitles, Translation & Dubbing Tool

Checksub is an AI-driven video localization platform built to help creators and businesses reach global audiences without the headache of manual subtitling or hiring voice talent. Simply upload a video and the platform automatically transcribes the audio, generates accurate subtitles, and translates them into more than 200 languages. From there, Checksub can go a step further by dubbing the video with lifelike AI voices, complete with voice cloning and lip-sync technology so the final output feels natural rather than robotic. Beyond translation and dubbing, Checksub includes a full-featured online editor that lets users fine-tune subtitle styling, timing, and animations to match brand guidelines or platform requirements. This makes it a versatile tool for everything from corporate training materials to viral social media clips. Whether the goal is expanding YouTube reach, improving accessibility, or localizing internal training content for international teams, Checksub streamlines a traditionally time-consuming and expensive process into a few clicks.

1. Upload your video file to the Checksub platform. 2. Let the AI automatically generate accurate subtitles from the audio. 3. Select your target language(s) and translate the subtitles into one or more of 200+ supported languages. 4. Optionally, generate an AI dub using cloned voices with lip-sync for a natural result. 5. Use the online editor to customize subtitle styling, timing, and animations before exporting or publishing.
