Subtitles vs dubbing — pick the job first
The two tools aren't really competitors; they do different jobs. Dubbing replaces the spoken audio with a translated voice track — Rask AI's specialty, complete with voice cloning and lip-sync. Subtitles keep the original audio and show translated text on screen — SubtitleFlow's specialty. If you only need captions, dubbing tooling is expensive overkill; if you need a spoken track, subtitles alone won't cut it.
Subtitle translation
For the subtitle job specifically, SubtitleFlow reads the cues around each line, so a sentence split across several subtitles still reads naturally and keeps its tone — and it never reflows your timestamps. Rask AI can output subtitles too, but as a by-product of its dubbing pipeline. If translating an SRT or VTT file is your main task, SubtitleFlow's subtitle translator is the specialized, lower-cost fit.
Pricing & free tier
Rask AI's pricing reflects its dubbing and voice-cloning engine, which is far more compute-heavy than text translation — so if subtitles are all you need, you're paying for capabilities you won't use. SubtitleFlow lets you start free with no account — a free preview translates the opening lines so you can judge quality before spending anything — then bills simple per-minute credits. For subtitle-only work, SubtitleFlow is usually far cheaper.
Which should you choose?
- Choose SubtitleFlow if you need translated subtitles — SRT/VTT with locked timing, bilingual export, context-aware AI, and a free, no-signup start.
- Choose Rask AI if your deliverable is a dubbed video — AI voiceover, voice cloning, or lip-synced translation of the spoken audio.
