Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
MyCase
- All plans are per-user pricing, not per-firm; previously paid fees are non-refundable
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.
