A few things you might be wondering.
What is NoteCube?
NoteCube is an AI voice recorder and note-taking app for iOS and Android by SecondEarth. It turns lessons and meetings into transcripts, summaries and documents you can keep updating.
What can I use for free?
Your first cumulative 60 minutes of transcription are free. Summaries and notes from transcribed content stay free. Free usage includes 3 AI document updates and 3 social drafts per day. Every host can start an event with up to 20 attendees without an attendee pass; transcription usage limits still apply.
What are living documents?
Living documents bring material from separate recordings into one document, such as a vocabulary collection or project notes. You can review entries, update their status and inspect revision history rather than starting a new document after every conversation.
Do event participants need the app?
No. Participants open the host’s QR code or link in a browser, enter their name and choose a caption language. Contact information is optional. The host uses the NoteCube app.
