Your private, all‑in‑one conversation and visual‑note recorder – 100 % offline. The meeting is more than a simple audio call—it enables interactive dialogue among participants. Your whiteboard sketches and notes are as valuable as the spoken conversation. The application seamlessly integrates voice transcription and camera captures into the meeting transcript, then generates a comprehensive summary that incorporates both forms of information. Why pay for a subscription when your device already works like a mini‑supercomputer, transcribing and summarizing everything locally? Offline Notes AI works entirely on your device, transforming spoken conversations and whiteboard drawings into accurate, searchable notes with zero internet connection. Just fast, private AI working for you. Never miss a detail—without sacrificing privacy. Perfect for Chalk Talk, Meetings, Interviews, Lectures, and anytime, anywhere. Key Features Transcribes spoken words in near real time and automatically separates each speaker. Analyzes photos with a Vision‑powered Large Language Model. Instead of traditional OCR, the app looks at the image, recognizes objects, handwritten sketches, diagrams, and any text, and produces a natural‑language description that captures the full meaning of the picture. Creates a single, searchable record that combines the spoken transcript and the Vision‑LLM description of every photo you captured. Summarizes the entire session—both the conversation and the visual content—into a concise overview you can read in seconds.
