What our research says

CoCounsel

CoCounsel is the safe choice for a firm already paying Thomson Reuters: research answers come with Westlaw citations, review tables trace every cell to a source, and it lives inside Word and the document-management systems lawyers already use. It is not a product you can try or price from the website — every number comes from a sales call — and the moat is the content licence, so a firm on Lexis gets far less from it.

Pros

  • Research grounded in Westlaw and Practical Law content with linked citations
  • Tabular document review scales to 10,000 documents against 100 questions
  • Works inside Word, Outlook and Teams and connects to iManage, NetDocuments and SharePoint
  • SOC 2 and ISO 42001 certifications and a stated no-training-on-customer-data policy

Cons

  • No public pricing and no free trial on the product pages
  • Value depends on an existing Thomson Reuters content subscription
  • Reported outcome figures come from a vendor-commissioned Forrester study

Spellbook

Spellbook wins on the thing that decides legal-tech adoption: it lives in Word, where the lawyers already are, instead of asking them to move. The cost of that is a sales process and a price you cannot check before you engage.

Pros

  • Native Word add-in means near-zero behaviour change for the people who have to use it
  • Benchmarks against both market norms and the firm's own precedent, not just generic templates
  • Well capitalised: $50M Series B led by Khosla in October 2025 plus $40M debt in March 2026
  • 7-day free trial is available without going through procurement

Cons

  • No published pricing at any tier, so budgeting requires a sales conversation
  • No API, which blocks integration into an existing contract lifecycle system
  • Priced per seat, so cost scales with headcount rather than contract volume
  • The vendor is now actively acquiring competitors, so the product surface may shift

Which one fits

Choose CoCounsel if you need

  • Tax and accounting practices on Checkpoint content

Choose Spellbook if you need

  • Small and mid-size firms and in-house teams doing high contract volume in Word
  • Practices with an existing precedent bank worth benchmarking drafts against
  • Teams that want redlining suggestions in the document rather than in a separate portal
