Overview

Octarine is a privacy-first, markdown-based note-taking app designed for speed, simplicity, and data ownership. Your notes are stored as local files you control completely, with optional Git synchronization to GitHub or GitLab for automated backups. The app features a powerful Command Bar for keyboard-driven navigation, Filter Views for database-style note organization, document linking with backlinks, hierarchical tags, and reusable content blocks. Octarine's AI Writing Assistant helps create and refine content with web search integration for current information, supporting 9 cloud AI providers plus local models through BYOK. The Ask Octarine feature lets you chat with your workspace to gain insights across all your notes. With multiple isolated workspaces, custom properties with frontmatter metadata, natural language date navigation, and beautiful themes, Octarine serves writers and knowledge workers who want AI-enhanced note-taking without sacrificing privacy or data control.
