Questions about automatic subtitling
What is Hello8?
Hello8 is an automatic subtitling platform: it transcribes your video or audio, translates the subtitles into more than 90 languages, then its AI Reviewer proofreads every subtitle. It is built for video creators, training teams, agencies and cultural institutions. The team has already delivered more than 10,000 videos.
How does Hello8’s automatic subtitling work?
You upload a video or an audio file. Hello8 transcribes the speech and translates it if you want. Then you run the AI Reviewer: it reads every subtitle and fixes the mistakes. You export to SRT, VTT, ASS, or a video with burned-in subtitles, depending on your plan.
Do I need an account or a credit card?
An account, created with Google or an email address, is all you need. It is free to start and no credit card is asked for at sign-up. To proofread a subtitle file you already have, SubReviewer needs no account for the preview.
What does the AI Reviewer fix?
Spelling and speech-recognition slips, grammar and agreement, word forms, capitals after a full stop, names from your glossary, hesitations, numbers according to your rule, false friends and mistranslations. Reading speed and line breaks are handled separately, by your thresholds.
