Evidence status

CoCounsel Legal

Checked 2026-11-03 at https://legal.thomsonreuters.com/en/c/westlaw/plans-and-pricing. Westlaw Advantage, described as next-gen AI legal research with Deep Research, starts at $288.60/month. Westlaw Edge with AI-Assisted Research starts at $170.95/month. The previously recorded Westlaw Advantage with CoCounsel Essentials price of $415.35/month is not on this page. CoCounsel Legal is presented without a self-serve list price. Broader packages remain sales-quoted.

Open verification questions
  • Standalone CoCounsel Legal seat pricing remains sales-configured.
  • Starting-at Westlaw bundle prices can be personalized by jurisdiction, attorney count, and term.
  • Vendor SOC 2 / ISO 42001 and no-training statements should be confirmed in the current customer agreement.

Official CoCounsel Legal product page describes Westlaw- and Practical Law-grounded research, analysis, and drafting, plus Word/Outlook/Teams integrations and a statement that customer data is not used to train underlying models. The $415.35/month Westlaw Advantage with CoCounsel Essentials figure was on the plans page on 2026-08-26. On 2026-11-03 that page starts Westlaw Advantage at $288.60/month and does not show $415.35. It is not a complete firmwide quote.

Spellbook

Spellbook’s official homepage does not publish a self-serve consumer price list. Official comparison materials describe custom per-seat annual subscriptions. No unverified dollar figure is reported as a list price.

  • Exact per-seat USD pricing is quote-specific and was not listed on the official homepage.
  • Zero-retention and training statements should be confirmed in the current DPA/contract, not only marketing copy.
  • HIPAA/SOC/GDPR resources on the trust center are vendor-published, not independently certified here.

Official homepage describes Word-native contract review and drafting, intake-to-signed-contract search, and a zero-retention statement that LLM providers do not train on or store customer data. A public trust center lists SOC 2 Type II and other vendor compliance resources. Treat those as vendor claims to verify in contract review.
