Freemium

AI subtitling, transcription and live captioning in 95+ languages, with dual ASR engines, enforced glossaries and broadcast-ready export formats.

Dual ASR Engines per Language Pair: Two recognition engines run together with millisecond timecodes and silence recovery for higher accuracy than a single-model pass.
Enforced Glossaries: User-defined terms are corrected before translation and every substitution is logged, so product names and jargon stay consistent across a project.
Code-Switching Support: Handles recordings where speakers mix languages mid-sentence, with particular strength in Cantonese alongside English and 95+ other languages.
Broadcast Export Formats: Delivers SRT, VTT, FCPXML, XLSX and Markdown, plus a burned-in subtitle master at up to 4K with custom caption styling.
Meeting Notetaker: Joins Google Meet, Zoom and Teams as a bot, or captures audio through a no-bot browser extension, then produces shared notes and action items.
Live Event Captioning: Generates translated captions in real time for webinars, classes and public displays, with separate audience and public-display views.
Searchable Interview Archive: Indexes long-form research recordings so a keyword returns every timestamped match across multiple sessions.
Automated Proofreading Score: Grades a finished subtitle pass and marks each cue as verbatim, timed or fixed so reviewers know what was changed.

Multilingual Film and Video Release: Subtitle a feature or launch film into several languages at once with a locked glossary and a burned-in 4K master.
Cantonese and Mixed-Language Transcription: Transcribe Hong Kong meetings, interviews or broadcasts where speakers switch between Cantonese and English.
Meeting Capture and Action Items: Record a weekly sync across Meet, Zoom or Teams and distribute shared notes with assigned follow-ups.
Accessible Live Events: Caption a webinar, lecture or conference session in real time and translate it so every attendee reads in their own language.
UX and Academic Research: Search an archive of interview recordings by theme and pull timestamped quotes across multiple participants.
Social Video Localization: Produce styled subtitles for YouTube, podcast clips and short-form social video in dozens of languages.
