A French subtitling and AI dubbing platform that transcribes, translates, voice-clones and lip-syncs your videos, priced in minutes of credit
Best for: Course creators, training teams and YouTubers who need accurate subtitles in several languages, and later want AI dubbing in the same tool.
The short answer
More creators choose Hello8 than Checksub, and it ranks higher in our captions and subtitles list. Pick Hello8 if you want documentary makers, agencies and training teams who deliver subtitles to clients or festivals in several languages and need them proofread, not just generated. Pick Checksub if you want course creators, training teams and youtubers who need accurate subtitles in several languages, and later want ai dubbing in the same tool.
Hello8: A serious subtitle tool aimed at professional delivery, with a proofreading AI Reviewer, frame-accurate editor and broadcast formats. It is overkill for TikTok captions, prices only in euros, and the free plan lets you see but not download your subtitles.
Checksub: A mature subtitling and translation tool with a real editor and a clear minutes-based credit system. Dubbing, voice cloning and the watermark removal all sit on the $48-a-month plan, and the site cannot agree on how many languages it supports.

Strengths and weaknesses
Hello8
- AI Reviewer checks subtitles against the video, which most caption tools skip
- Clear credit math, 1 credit per minute for transcription or translation
- Purchased top-up credits never expire
- Broadcast-style formats and reading-speed checks suit festival and client delivery
- GDPR compliant and hosted in Europe, with content not used for training
- Active development; the public changelog shows releases every few weeks
- Prices are in euros only, with no USD option we could find
- Free plan has no downloads, so you cannot use free subtitles anywhere
- AI Reviewer costs 5 credits a minute, so it burns through Starter fast
- No animated caption styles, emoji or hooks for TikTok, Reels or Shorts
- Pricing page lists SRT, VTT and TXT export; the features page lists SRT, VTT and ASS
- No refunds on unused subscription or top-up credits
- Despite its directory listing as a video translator and dubber, there is no dubbing or voice feature
Checksub
- Credit math is published and simple, measured in minutes of video
- Unused yearly credits roll over to the next year; monthly credits last six months
- Free trial covers about an hour of video and every feature
- Subtitles, translation and dubbing live in one editor
- Dubbing keeps the original music and background audio, per Checksub
- 4K export and 4GB uploads on every paid plan
- Dubbing, voice cloning and lip-sync need the $48 Starter plan or higher
- Junior allows only one translation per project, and so does Starter
- Language counts disagree across the site (80, 120, 180, 187 and 200 all appear)
- Lip-sync is still labelled beta and costs 5 minutes of credit per minute of video
- Every translation also burns credits for the source transcription
- Single user only below Enterprise
