What is TheSubAI?

TheSubAI is a browser-based AI subtitle translator for people who work with subtitle files rather than video timelines. Upload an SRT, VTT, ASS, SSA, SBV or TTML file, choose one of 130+ target languages, and get back the same file with translated text and byte-identical timing.

What separates it from a generic translator is the two-pass approach. The first pass translates with the surrounding dialogue as context; the second refines phrasing, resolves idioms and slang, and fixes what machine translation usually gets wrong in subtitles - grammatical gender, formality levels, and lines split mid-sentence by the timing.

Alongside it is a free toolbox that needs no account: format converter, resyncer with frame-rate conversion, encoding fixer, SDH/HI cleaner, dual-subtitle merger, validator and styler - plus a YouTube subtitle translator and an audio-to-subtitle converter.

Pricing is pay-as-you-go: first 500 lines free, then credit packs from $5. No subscription, credits never expire.
