Use tool ↗About Hei.io
Hei.io takes a video or audio file, or a YouTube link, and produces synced captions, translated subtitles and dubbed voiceovers without a studio. It covers more than 140 languages with over 440 synthetic voices, and instant voice cloning keeps a dub close to the original speaker in 32 of them. Exports include MP4, MP3, SRT, VTT and TXT, and lip-sync is still listed as coming rather than shipped. It is aimed at creators, video agencies and marketing teams localizing content, and is run by HeiTech Oy of Espoo, Finland.

Pros & cons of Hei.io
Hei.io covers the full localization pipeline, captions, translated subtitles, and dubbed voiceover, in one place, which saves stitching together a transcription tool and a separate dubbing tool. Voice cloning in 32 languages is a real differentiator versus subtitle-only tools, though lip-sync is still listed as coming rather than available. The plan structure mixes per-minute plan allowances with a separate pay-as-you-go hourly rate, which is hard to compare at a glance.
Pros
- Combines captioning, translation, and AI dubbing in one workflow
- 440+ voice options and cloning across 32 languages
- Exports to standard formats (MP4, MP3, SRT) rather than a proprietary player
- 140+ supported languages for translation
Cons
- Lip-sync is not yet available, only listed as upcoming
- Pricing mixes monthly plan minutes with a separate hourly pay-as-you-go rate
- No visible permanent free plan, only a trial
Best for
- Video agencies localizing content into many languages at once
- YouTube creators wanting dubbed versions instead of just subtitles
- Marketing teams needing translated voiceovers without hiring voice actors
Not for
- Anyone needing lip-synced dubs today rather than in a future release
- Users who just want free automatic captions and nothing else
Watch out: Check whether the advertised price is a limited-time discounted rate before budgeting for renewal, since the site lists both a regular and a halved promotional price side by side.
