Why Choose Octarine Over Agenda

Flexible knowledge base over rigid timelines

Octarine is built on a simple but powerful philosophy: your notes should truly belong to you. Not locked in proprietary databases, not held hostage by subscription services, but stored as plain Markdown files that you control completely.

Everything You Need, Nothing You Don't

Octarine ships complete. While other note-taking apps require hunting for plugins, configuring extensions, and hoping they all play nicely together, Octarine gives you a thoughtfully curated set of features that simply work out of the box:

• WYSIWYG Markdown Editor – Write in rich text that stays as clean Markdown
• Daily Desk – Start each day with a dedicated space for tasks and thoughts.
• Linked Notes – Build connections between ideas with bidirectional linking
• Graph View – Visualize your knowledge web at a glance
• Templates – Create reusable structures for recurring note types
• Git Sync – Automated backups to GitHub or GitLab
• Ask Octarine – AI-powered chat that understands your entire note collection
• Multi-color Highlights – Organize with up to 6 different highlight colors
• Command Bar – Lightning-fast keyboard-driven workflow
• Split Panes & Tabs – Work with multiple notes simultaneously

No plugin marketplace to navigate. No compatibility issues to troubleshoot. Just a cohesive, well-designed experience.

Octarine vs Agenda

90% Smaller, 100% Capable

Built with Rust and Tauri, Octarine achieves something remarkable: it's 90% lighter than typical note-taking apps without compromising on features or experience.

What this means for you:

Your Data, Your Terms

Your notes live on your device, in folders you choose. Not in our servers. Not in our databases. We don't want to know what you write—and we've designed Octarine so we never have to. Works fully offline. Your data never touches our servers. Period.

• Smart Dates – Use natural language to navigate your Daily Desk
• Recently Viewed – Quickly jump back to what you were working on
• Multiple Workspaces – Separate work, personal, and projects with distinct settings
• Focus Mode – Fade everything except your current sentence
• 13+ Beautiful Themes – Find the look that helps you concentrate
