Reflect is a SaaS note-taking application built around networked, backlinked notes and a graph-based knowledge architecture. It integrates OpenAI's GPT-4 for text-based AI assistance and Whisper for voice transcription, with custom prompt support. Notes are end-to-end encrypted, meaning even Reflect cannot read your content. The platform exposes an API for programmatic access and supports Zapier for no-code automation, plus native integrations with Google Calendar, Outlook, Readwise, Chrome, Safari, and Kindle.
