I'm Logan. Built DeepTutor after running a beta signup last month.

Got 200 researchers in 48 hours. Asked them to screen share their workflow.

What I saw: Copy text from Zotero → paste into ChatGPT → upload PDF to NotebookLM → back to Zotero → repeat.

Everyone was doing this tab circus just to ask questions about their own papers.

So I forked Zotero and embedded the chat directly into the library.

Technical bits: - Built on Zotero's open source codebase - One-click import of existing workspaces - Understands figures/tables, cites exact locations - Agent mode: chat with entire library without manual file selection

Current state: - Some plugin compatibility issues (fixing) - PDF only for now - Paragraph-level highlights (working toward word-level)

Next: MCP integration with Claude Code.

Happy to discuss architecture or product decisions.

(I'm not affiliated with Zotero, though I've enjoyed the advantages of their open source software for research and bibliographic metadata)

pyzotero, paperqa.contrib.ZoteroDB,

Paperai supports "Report Schemas" in YAML that could be useful for systematic reviews

IIRC the Zotero Connector doesn't work on students' Chromebooks.

Tabulator was a cool extension. A clone of Tabulator as a Web Extension that has local storage with a remote sync option would be useful.

Zotero does bibliographies with CiteProc and CSL Citation Style Language;
