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
Legalon
Pros
- + 135+ attorney-built playbooks mean policy-grounded review on day one with zero configuration — the differentiator versus chat-based review tools
- + Review and redline inside Microsoft Word as well as the web platform, sharing one review engine across both
- + Unlimited review and redline volume on paid plans, with unlimited assistant chat and prompt library
- + Enterprise security posture (ISO 27001, ISO 27011, SOC 2 Type II) and an explicit no-third-party-training data policy
- + International reach: Translation Agent across 28+ languages and attorney-built playbooks covering 23 countries
Cons
- - No free tier — only a 14-day trial — and the Individual plan runs $550/month billed annually per third-party sources at time of writing
- - The operational depth (custom playbooks, Vault intelligence, intake and triage agents) sits in higher suites behind demo-gated pricing
- - Not a full CLM: no negotiation workspace and lighter repository analytics than dedicated contract-intelligence platforms
- - Matter-management and agent features shipped July 2025 — limited long-term reliability data
- - Review quality depends on playbook coverage; exotic contract types still require lawyer judgment
