Description

Reflect is a beautifully minimalist, open-source, and AI-native note-taking application designed to function as a digital second brain. Built with end-to-end encryption, it mirrors human thought patterns by associating notes through automatic backlinks. Reflect natively integrates models like Claude Sonnet 3.7, GPT-4, and Whisper to assist with summarizing links, editing custom prompts, and audio transcribing. It also offers friction-free integrations with Kindle highlights, Google Calendar, Outlook, and web browsers via Safari and Chrome extensions.
