Hello8

Hello8 generates subtitles and translations in more than 90 languages, then runs an AI Reviewer pass that flags grammar, conjugation, punctuation, hesitation and glossary errors with one-click fixes. It targets documentary, corporate, agency and cultural-sector teams that need publish-ready captions rather than raw transcripts.

Hello8 is a subtitle and translation platform built around a simple premise: the AI that writes your captions should also check them. You upload a video or audio file, the system transcribes the speech, translates it into your target language, and then a separate AI Reviewer pass reads every line and flags problems before the file reaches you. The output is a preview you can publish straight away, or correct first if you prefer. The reviewer is the part that separates Hello8 from a generic transcription service. It checks for grammar, verb conjugation, punctuation, hesitations and glossary consistency, and it shows each issue with a timestamp, a short explanation and a proposed correction you can apply in one click. The company frames this as eight quality criteria: duration, text, segmentation, rules, translation, speaker identification, styling and sync. The pitch is that manual proofreading of subtitles can take six to ten times the length of the video, while the automated pass runs in minutes. Cleanup is handled at the same time. Filler words, repeated phrases and non-verbal cues such as laughter or throat clearing are stripped from the transcript, which matters most for interview footage where raw speech reads badly on screen. Supported output includes SRT, VTT and a subtitled video file, and the language list runs past 90 entries with dedicated pages for major languages and their specific quality checks. Hello8 positions itself for professional localization rather than casual captioning. Documentary filmmakers, corporate learning teams, video agencies and museums are the named audiences, and each has its own use case page. Data protection is part of the offer: GDPR compliance, encryption in transit and at rest, EU hosting with some vetted processing partners outside the bloc, and a stated policy that content is never used for model training. Competing tools tend to sell raw transcription speed or translation breadth; Hello8 sells the review layer on top of both.
