RECORD. TRANSCRIBE. ASK. Cosmonote is the AI assistant that captures what you hear and what you read, turns it into clear notes, and answers your questions from everything you kept. YOU LISTEN, IT TAKES THE NOTES Hit record in a meeting, a lecture, an interview. Two hours come back as clear notes: the takeaways, the open questions, the full summary, and a word-for-word transcript. ASK ALL YOUR NOTES Your assistant has read every note you recorded. "Sum up Monday's meeting" "What keeps coming up across all my notes?" "Explain this chapter in simple terms" Answers in seconds, based on what was actually said. IMPORT AN AUDIO OR VIDEO FILE A voice memo, someone else's recording, a file from WhatsApp: import it and get clean notes. A YouTube link works too: paste it, notes arrive. FLASHCARDS AND QUIZZES FROM YOUR OWN NOTES Ask for flashcards from a note, get quizzed on the week. Everything comes from what you captured, not a generic textbook. SCAN ALL YOUR DOCUMENTS Photograph a page, a contract, a handout, a notebook: the text comes out on your phone, page after page. Handwriting too. The pages stay in the note, and the assistant reads them like everything else. YOUR CALLS TOO Connect your calendar and a bot joins your Zoom, Meet, and Teams calls. Think out loud in a voice memo: Cosmonote turns it into clear content with tasks extracted automatically. USE WITH YOUR FAVORITE AI Connect Cosmonote to Claude (via MCP) or ChatGPT (via a custom GPT) and work on your notes from the chat you already use. PERFECTLY STRUCTURED NOTES Every note is organized automatically: - TLDR: the key points at a glance - Open questions: what still needs clearing up - Summary: the full context - Transcript: word for word, with speaker labels SUBSCRIPTION The features described above (AI notes, assistant, scanning, flashcards, quizzes, imports) require a Cosmonote Pro subscription. Your first 3 notes are free. Billed through your App Store account, cancel anytime. Stop retyping everything. Hit record, Cosmonote handles the rest. --- Privacy Policy: https://cosmonote.ai/privacy/ Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
