AI captions, animated emojis and multi-platform resizing in seconds
Uploads are transcribed automatically in 100+ languages, making the tool usable for non-English and multilingual creators.
Word-by-word animations, emphasis and emoji can be applied from presets, then fully customised for fonts, colours, size and position.
Fix words and adjust caption timing on a simple timeline instead of re-recording or exporting to a separate editor.
Reformat a single captioned project for TikTok, Reels, Shorts and LinkedIn aspect ratios without manual reframing.

Studio-quality podcast and video recording, editing, and publishing in your browser
Every participant records locally on their own device, capturing up to 4K video and 48kHz uncompressed audio in separate tracks that stay sharp regardless of connection quality.
Edit video by editing the transcript — search, cut, copy, and paste words and the footage updates. AI then removes filler words and silences or fixes eye contact in one click.
Turn a finished session into promotional assets: short clips optimized for each platform, thumbnails, headlines, show notes, transcripts, and translations or dubs in over 30 languages.
Broadcast in full HD 1080p to unlimited destinations simultaneously, or host webinars with registration, branded emails, Q&A, live call-ins, polls, and HubSpot lead capture.
