Master Notion and Zotero for Effective Research

Notion

If you are using Notion you might already have Notero installed to manage you references and annotations.

One issue that always bugged me and I never had the time to explore is that autotagging in Zotero is not fantastic.

And when I am in research deep dive I am not always great in adding meta data. So, while catering for my pain management, aka reading in bed I have time to explore.

This is the result

What’s in the guide

Part 1 — Notion setup

Add a Tags property (Multi-select, exact capitalisation) to your Notero database. The property schema table lists all supported Notero fields. Connect Notero via OAuth and enable “Sync when items are modified” — that’s the hook the whole pipeline relies on.

Part 2 — Actions & Tags configuration

Install the plugin, store your API key securely in Zotero’s own preferences (not in the script), and create a createItem → Script action.

Part 3 — The automation script

The core JavaScript uses async/await and fetch() inside Zotero’s privileged context. It:
Guards against non-regular items and missing/short abstracts
Reads the key from Zotero.Prefs (never hardcoded)
Sends title + abstract to the LLM with a librarian-style system prompt
Parses the JSON array response with a regex fallback for non-compliant models
De-duplicates against existing tags, then calls item.saveTx() — which automatically triggers Notero’s sync

Part 4 — Provider swaps

Drop-in replacements for Anthropic Claude and local Ollama, including the CORS flag Ollama needs to accept requests from Zotero.

Part 5 — Timing details

Explains why saveTx() is the correct sync trigger, plus a Zotero.Notifier observer pattern for when the browser connector saves abstract metadata in a second pass.

Part 6 — Troubleshooting table

Seven common failure modes with specific fixes.

Part 7 — Enhancements

Colour-coding AI tags teal in Zotero’s tag panel, writing to a separate Extra field instead of mixing with manual tags, and exporting the action to a .yml backup.
