AI Subtitle Editor & Translator

SubLime uses AI to read and understand your entire file at once. This means it grasps the ongoing dialogue, specific terminology, and the actual tone of your video, resulting in edits and translations that feel completely natural and human.

Yes, your privacy is fully protected. We strictly use your files for processing and do not store them permanently. Most importantly, we never use your subtitle data to train any AI models. Your current session is saved only in your own browser so a reload does not lose your work, and it is removed when you start over.

SubLime currently does not charge users. To keep the free service sustainable, each public IP address receives a daily AI allowance. For typical subtitle proofreading, this is roughly 15,000–80,000 subtitle characters per day. This is an estimate rather than a fixed character limit: the actual amount varies by language, proofreading versus translation, context length, and task complexity. Users on the same network share the allowance, which resets daily at 00:00 UTC.
