Limitations & when to consider alternatives

Known limitations

  • Google Docs feature differences. The Google Docs add-in does not currently provide Draft, Compare to Market, Definitions, Benchmarking, or full Word-equivalent redlining.
  • OCR is required for searchable PDFs. Scanned PDFs without OCR can upload, but Associate cannot reference their contents.
  • Resource sharing is not fully granular. Resources can be shared with teams or the organization, but not with individual users; library sharing is folder-level.
  • No audit logs or dedicated admin portal. Spellbook currently does not provide audit logs for role changes or resource sharing, and administration occurs in the add-in.
  • Word documents are the only directly editable Associate files. Associate can reference several file types, but only DOCX files can be edited directly.

Look elsewhere when

  • You need a native mobile application.
  • You need a public developer API.
  • You need full feature parity in Google Docs.
