Overview

AI Subtitle Translator batch-translates subtitle files – hundreds at a time – across more than 100 languages and seven formats (SRT, VTT, ASS, LRC, SBV, SMI, TXT), with automatic timestamp alignment and a built-in editor for post-translation adjustments. A single file can translate into over 100 languages, or into up to five languages simultaneously in one pass.

True batch processing across hundreds of files, rather than one-at-a-time upload, is what actually makes this useful at a creator or studio scale, where a channel with a large existing library needs its whole catalog translated, not just its next upload. Context-aware translation – demonstrated handling idiomatic phrasing correctly rather than literally – also matters specifically for subtitles, where a literal translation of an idiom reads as obviously wrong to native speakers.

Credit-based pricing (0.1 credits per 1,000 characters, tiers from $9.90-$49.90/month) needs modeling against real subtitle volume – a large back-catalog translation project could consume a monthly allowance quickly. The free tier’s 14-day file retention also means downloading results promptly rather than treating it as storage.
