How it works
Cataloger.me is a macOS desktop app. Links and files become markdown notes in a folder you control.
Capture
- Paste a URL — the app fetches the page and writes a structured note.
- WhatsApp — forward links to your bot; processing runs on your Mac when the app is running.
- Folder watch — drop PDFs or HTML into a watched directory; new files become notes automatically.
What you get in each note
Every capture becomes plain markdown with YAML frontmatter, typically including:
- Title and source URL
- TL;DR and key points
- A mermaid diagram when useful
- Topic folder placement for your library
Open the same folder in Obsidian if you want its graph and plugins—no export step required.
Summarization
Default: bundled on-device assistant (downloads on first run; works offline after setup).
Optional: connect Ollama, OpenAI-compatible APIs, or other providers you already use. You decide what leaves your Mac.
Where files live
Notes and prompts live under directories you choose in app settings—portable markdown on disk, not a proprietary cloud vault.
