Create, translate, edit, and export video subtitles in one workflow. This app is designed for video creators, editors, students, language learners, and anyone who needs a practical way to add subtitles to videos. You can use locally deployed models to recognize speech and translate subtitles, or use OCR to detect existing on-screen subtitles and translate them into another language. Whether you are adding captions to your own videos, translating videos without subtitles, or preparing subtitle files for editing and publishing, the app helps you manage the process from recognition to final export. Key features: Local speech recognition and translation Use locally deployed models to process video audio and generate subtitles. This is useful when you want more control over your workflow and prefer not to rely entirely on online subtitle services. OCR subtitle recognition For videos that already contain on-screen subtitles, OCR can help extract the text so you can translate, correct, and reuse it. Subtitle editing and correction Edit recognized text, adjust subtitle timing, refine translations, and correct segmentation before exporting. This makes it easier to prepare subtitles that match the pace and meaning of the video. Export video or SRT Export a video with subtitles embedded, or save subtitles as an SRT file for use in video editors, media players, or other production tools. Useful for: Adding subtitles to personal videos, vlogs, tutorials, and courses Translating videos without subtitles Extracting and translating existing on-screen subtitles Creating bilingual subtitles Exporting SRT files for editing, publishing, or archiving From subtitle recognition to translation, editing, and export, the app brings the main subtitle workflow into one place so you can create captions with more control and less switching between tools.
