Frequently asked questions
Can I dub Japanese videos to English for free?
Yes. Spimov's free plan lets you dub your first Japanese video into English with AI — no credit card required. Paid plans add more minutes, lip sync, and remove the watermark.
Will the English dub keep the original speaker's voice?
Yes. Spimov clones the original speaker's voice, so the English version sounds like the same person and preserves tone and emotion instead of a generic voice.
How accurate is the Japanese to English translation?
Spimov uses large language models for context-aware translation — adapting idioms and meaning rather than word-for-word — then aligns the English audio to the video timing.
