European transcription and subtitle platform with AI subtitles in 150+ languages, a collaborative editor, burned-in MP4 export and optional human proofreading

Best for: Creators, educators and small teams who subtitle long-form or multilingual video and want accurate, editable subtitle files with an option to pay for human review.

The short answer

More creators choose Hello8 than HappyScribe, 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 HappyScribe if you want creators, educators and small teams who subtitle long-form or multilingual video and want accurate, editable subtitle files with an option to pay for human review.

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.

HappyScribe: A mature, privacy-focused subtitle and transcription platform with broad language coverage, proper subtitle file formats and human proofreading when accuracy matters. It is not a flashy short-form caption styler, the free plan is only a 10-minute trial, and the product's focus has shifted toward meeting notes.
