# SubtitleFlow

> SubtitleFlow is a free online AI subtitle translator and audio/video transcription tool. It translates SRT and VTT subtitle files into 100+ languages with context-aware AI that never shifts your timestamps, and turns audio and video into accurate, timed captions — all in the browser, with no signup required to start.

Unlike a general translator (e.g. Google Translate) or an all-in-one video editor, SubtitleFlow is built specifically for the subtitle job: it translates each cue in context so meaning stays natural across a sentence split over several lines, preserves every timestamp so the output stays in sync, supports bilingual (dual-language) export, and provides a line-by-line editor to review the result before exporting clean SRT/VTT. There is a free tier with no account, then simple per-minute credit pricing.
