Documents and notes decision
Paperpile
A technically competent developer can build a usable subset (capture, store, Drive sync, basic citation insertion) in a multi-week effort, but matching Paperpile's polish, full integrations, and enterprise features would be costly; consider self-hosting prior-art projects first.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Capture reference metadata + PDF from webpages, store and index references, sync/store PDFs in users' Google Drive, insert citations into Google Docs/Word, view/search and annotate PDFs in-browser.
What it still won’t have
- Enterprise features (SSO, custom SLAs, HIPAA support, vendor security reviews)
- Polish and cross-platform native apps (iOS/Android/Word/Google Docs official plugins)
- Large-scale reliability, vendor-managed hosting, and formal support/SLAs
- Advanced integrations and long tail publisher support
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal web-based reference manager using: React frontend, a Chrome extension, Node.js + Express backend, Postgres DB, and Elasticsearch (or Postgres full-text). Implement: Google OAuth sign-in; extension that captures metadata and downloads PDFs; backend endpoints to create/update/delete references and store annotation metadata; sync PDFs to the user's Google Drive via Google Drive API and store file IDs; a Google Docs add-on (or Docs API integration) to insert formatted citations and generate bibliographies (supporting at least one citation style); full-text search across metadata and PDF text; an in-browser PDF viewer with highlights saved to the backend. Out of scope: enterprise SSO/SAML, paid billing flows, HIPAA compliance, advanced publisher scraping, and mobile native apps. Include error handling, retry logic for Drive API calls, unit/integration tests for core API endpoints, and a README with deployment steps (Docker + managed Postgres).

- Price verified on pricing page+3
- Evidence score58
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
