Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

NetDocuments

  • Quote-only pricing per user with no published rates
  • Migrating an existing document store is a substantial project, and legacy metadata rarely survives cleanly
  • Aimed at mid-size and large firms; solo practices find it heavier than needed
  • Adoption depends on fee earners filing correctly, and habits are the hard part

Spellbook

  • It publishes no accuracy figure for its own output and no independent evaluation exists, so a firm must run its own assessment on real agreements.
  • The ten times more accurate claim originated in a funding announcement as a statement of intent and has no methodology, dataset or baseline behind it.
  • Contract text is processed by third-party model providers, so despite the zero data retention agreements this still needs checking against client confidentiality terms and outside counsel guidelines.
  • Pricing is not published, so seat cost cannot be compared against competitors without booking a demo.
  • It is a drafting assistant rather than a contract lifecycle system, so it does nothing for execution, obligation tracking or renewals.

Answered from the vendors’ own pages

NetDocuments: What does NetDocuments cost?

It quotes per user and does not publish rates.

Spellbook: Is Spellbook's accuracy independently verified?

No. It publishes no accuracy figure of its own, and no third-party evaluation has been published. It did not participate in the Vals Legal AI Report, the main independent lawyer-baselined benchmark. Evaluate it on your own agreements during the trial.

NetDocuments: Why not just use SharePoint or Dropbox?

Neither expresses matter-centric security or ethical walls in an auditable way, which is a professional obligation rather than a preference in legal practice.

Spellbook: Which models does it use and where does our text go?

Spellbook names OpenAI GPT-5 and Anthropic Claude models, and states it has zero data retention agreements with both providers. Confirm the current terms and subprocessor list against your client confidentiality obligations before use.

NetDocuments: Does it handle email?

Yes, capturing correspondence into the matter record, which is where most legal email otherwise fails to land.

Spellbook: What does it cost?

Pricing is per seat but is not published. The vendor quotes it after a demo, so the seat rate cannot be compared with competitors in advance.
