Submind

What is Submind?

Submind is an offline-first note app that helps you capture ideas, meetings, and media — then chat with that content using AI. Record high-quality audio, transcribe it offline or online, and get concise summaries, highlights, and action items. You can ask questions of videos, PDFs, images, and web links to extract key points without rewatching or rereading. Everything is stored locally for privacy, with optional secure online AI features and easy exports to PDF, DOCX, Markdown, text, or images.
