SubLime Captions is a web-based AI editor for refining and translating subtitle files.
What SubLime Captions is
SubLime Captions is a web-based AI editor for refining and translating subtitle files. It works with .srt, .vtt, and .ass formats, and can proofread spelling, punctuation, and grammar. Users can also give plain-language instructions to change a subtitle’s tone, summarize its content, or adjust localization. Filters can remove filler words, stutters, or profanity, and change punctuation. For translation, SubLime says it considers surrounding captions, terminology, and style preferences, while reading the full file to follow dialogue and tone. Listed languages include Chinese, English, Japanese, Korean, French, and Spanish. SubLime says files are processed rather than kept permanently, and are wiped when the session closes; subtitle data is not used to train AI models. The Free plan costs nothing. Its daily AI allowance is an estimate, roughly 15,000–80,000 subtitle characters for typical proofreading, shared by users on the same public IP and reset daily at 00:00 UTC. Actual allowance varies with language, task, context length, and complexity.
