Apioni vs Obsidian
Both keep your writing as plain .md, and both are honest about letting you leave. The split is who does the work of connecting it. Obsidian hands you files and a deep toolbox and trusts you to build the system. Apioni reads what you wrote, builds the structure itself, and lets you ask questions against it.
| Feature | Apioni | Obsidian |
|---|---|---|
| Where notes live | Your Apioni account — open a browser on any machine and everything is there | Plain .md files in a folder on your device |
| Note format | Plain Markdown | Plain Markdown |
| Who builds the connections | Apioni does — notes become atoms, and people, projects, books, and events are extracted, tagged, and related as you write | You do — links, tags, and folders are yours to author and maintain |
| Search | Full-text and meaning in a single query | Full-text search across the vault |
| AI | Built in — three rewriting strengths and chat grounded in your notes, with nothing to configure | Through community plugins, typically with your own model API key |
| Answers you can check | Every claim names the atoms it came from, and thin evidence gets a refusal instead of a guess | Depends on the plugin you install |
| Works without a connection | ✗ Notes sync and AI runs server-side, so it needs a connection | ✅ Fully local |
| Graph view | ✅ Notes, atoms and objects, with focus and depth | ✅ |
| Canvas (freeform boards) | ✗ Not part of Apioni | ✅ |
| Plugin ecosystem | ✗ Not part of Apioni | ✅ Large community ecosystem |
| Getting your content out | Export a note, a folder, or everything as Markdown, Word, PDF, HTML, or JSON | The files are already yours on disk |
| Pricing | Free · Pro $12/mo ($10/mo billed annually) | Free for personal use, with paid sync and publishing add-ons |
TL;DR
- Choose Apioni if: maintaining the system is the part you never get around to, and you would rather write and have the links, tags, and answers come back on their own.
- Choose Obsidian if: you want the files on your own disk, you enjoy tuning the setup, or you need graph view, canvas, and the plugin ecosystem.
