Casetext CoCounsel
Pros
- + Citations in my checks resolved to real documents in the account library, with KeyCite treatment signals attached
- + Task-shaped outputs (research memos, obligation logs, timelines) rather than raw chat
- + Word drafting anchored to Practical Law precedent cut my NDA first-draft time to about 15 minutes
- + Document review reliably handles first-pass summarisation and clause extraction
- + Bundled Westlaw and Practical Law access removes the tab-switching that slows legal research
Cons
- - Standalone Casetext was retired on 2025-04-01; you cannot buy the old product at any price
- - No self-serve trial or published list price — everything routes through a configurator or sales call
- - Estimated $293/seat/month floor for the entry tier (Spellbook's configurator read, June 2026), roughly 30% above the old $225 standalone price
- - US law is the centre of gravity; most of the value evaporates for non-US practice
- - Missed a cross-reference in a lease amendment during my document review test — human review still required
Contractbook
Pros
- + Post-trial limited free plan rather than hard lockout — unusual retention design per contractbook.com/pricing
- + AI Import extracts structured fields from uploaded PDFs with OCR for scans (Centralize and up)
- + Praise for ease of use and support is consistent across G2 (4.7, 75 reviews) and Capterra (4.7, 78 reviews)
- + Unlimited eSignatures within the per-tier annual contract caps (100/350/500 per year)
- + Automation layer plus Zapier (3,000+ apps), Make.com, HubSpot, Pipedrive and Salesforce hooks
Cons
- - No generative drafting or legal research AI — the intelligence is extraction and reminders only
- - Centralize and Accelerate pricing is quote-based on the public site; budget discovery requires a call
- - Dynamic templates with conditional logic and full automations gate at Accelerate, not Centralize
- - Annual signed-contract caps (100/350/500) bound heavy users; upload cap is 50 on Essential
- - AI extraction accuracy is not benchmarked publicly — unverifiable before a pilot
