Turn lectures and meetings into notes you can study | Free tier | - **Capture from many sources**: Record live, upload MP3, WAV, M4A, AAC, or OGG audio, import PDF, DOC, or DOCX files, add public web pages or YouTube videos, or scan up to 9 images per note.

AI receptionist and business agent for local businesses | Free tier | - **24/7 AI Receptionist**: Answers inbound calls with a real conversation instead of voicemail or a phone tree.
