Where each stands

Casetext CoCounsel

Pros

  • Zero hallucination design backed by comprehensive Thomson Reuters legal databases
  • Saves litigation attorneys dozens of hours on discovery document review and research
  • Understands complex multi-jurisdictional legal doctrine and precedent

Cons

  • Priced strictly as enterprise and professional legal software subscriptions
  • Requires legal training to construct optimal litigation search questions
  • Engineered specifically for US legal systems and litigation practice

Spellbook

Pros

  • Lives inside Word, so there's no context-switching to a separate app for drafting or review
  • Playbook approach encodes a firm's actual negotiation positions rather than generic AI suggestions
  • Strong fit for transactional practices with high contract volume across employment, vendor and commercial agreements

Cons

  • Pricing isn't published and third-party estimates vary widely between plans, so a real quote is needed before budgeting
  • Only available as a Word add-in, so teams drafting outside Word get no benefit from it
  • Quality depends on how well a playbook is set up — a thin or generic playbook produces thin, generic redlines

Which should you choose?

Casetext CoCounsel is the better fit for:

  • Conducting fast, reliable case law research across state and federal jurisdictions
  • Reviewing thousands of litigation discovery documents for relevant key facts
  • Drafting deposition outlines and witness cross-examination question lists
  • Checking legal briefs for citation accuracy and verifying good law status

Spellbook is the better fit for:

  • Reviewing and redlining vendor or customer contracts against standard positions
  • Drafting first-pass clauses for common commercial agreement types
  • Giving in-house counsel a consistent negotiation position across many contracts
  • Getting a plain-language summary of an inbound contract before reviewing it
  • Flagging where a counterparty's terms sit outside market norms
  • Letting a small legal team handle contract volume that would otherwise need outside counsel
