Both platforms offer transcription and subtitles — but the approach to quality couldn't be more different. Here's an honest comparison to help you decide.
HappyScribe is a transcription and subtitle platform trusted by over 6 million users. It offers AI-powered transcription in 120+ languages with optional human proofreading, a meeting notetaker for Zoom, Meet, and Teams, and a web-based collaborative editor. It is a solid general-purpose tool for converting speech to text.
Hello8 is a professional subtitling and video localization platform. It offers AI transcription and translation in 90+ languages with optional human review for broadcast-quality results. Every file goes through reading speed validation, timing checks, and language-specific typographic rules. Hello8's unique AI Reviewer checks conjugation, grammar, translation, hesitation, and glossary like a human would, leaving comments you can approve in one click.
A high-level overview before we get into the details.
A side-by-side look at what each platform offers for professional subtitle workflows.
Most platforms bolt on a chatbot that answers questions about your file. Hello8's AI watches your video, reads your subtitles, and tells you exactly what to fix — then lets you apply the fix in one click.
You type a prompt, you get a wall of text. The AI is completely disconnected from the subtitle editor.
The AI reviews your entire subtitle file proactively. It posts comments directly on problematic subtitles — each with the exact issue and a proposed fix.

HappyScribe's AI-only transcription starts at $0.20/min with up to 85% accuracy. Hello8 targets higher accuracy with its AI Reviewer catching grammar, conjugation, and translation issues automatically. For projects where quality matters — and re-work costs more than getting it right the first time — Hello8 delivers better value.
HappyScribe focuses on transcription accuracy but doesn't include automated subtitle-specific QA. Hello8 validates reading speed (CPS), characters per line (CPL), and language-specific typographic rules on every subtitle file.
HappyScribe supports 120+ languages for AI transcription. Hello8 supports 90+ languages with full transcription, translation, and subtitle validation — including language-specific QA rules for each target language.
Hello8 is optimized for video and media content — subtitles and professional translations. If you primarily need meeting notes and real-time transcription, HappyScribe or a dedicated meeting tool may be a better fit.
AI generates the initial transcription and translation. Hello8's AI Reviewer then checks for conjugation, grammar, translation, and hesitation issues, leaving comments you can approve in one click. For projects that need it, you can add human review as an option — expert linguists refine accuracy, tone, and cultural context.
