Home / Contract Review & Drafting AI
6 toolsAI that reviews, redlines, summarizes and drafts agreements inside Word or a browser, against your own playbook and precedents.
The six tools here are mostly Word add-ins, and they split by how they are priced. Three post a per-user price: Gavel Exec redlines whole agreements, flags missing terms and applies the firm's playbooks inside Microsoft Word at $160/user/mo (or $1,740 per user billed/yr), with 25 free queries to start; Law Insider SimpleAI drafts, reviews and redlines with a database of 20M+ contracts and 200M+ clauses behind it, at $1,790/user/yr after a 7-day trial; and Macro, the one browser workspace in the set, has a free macro-sm tier and plans from $20/user/mo with all features in every plan. Three are priced by quote: Spellbook, a Word add-in with Review, Draft, Ask, Benchmarks and Playbooks plus the Spellbook Associate multi-document agent; LegalOn, whose Core Review tier is written for solo attorneys and fractional GCs; and Lexis Create+, which brings the LexisNexis Protégé assistant and Shepard's citation validation into Word and Outlook.
Across the set the AI reads an agreement, redlines it against the firm's playbook or market terms, flags what is missing, summarizes the other side's changes and drafts new clauses or whole documents from precedent, with Macro's AI Citations and Lexis Create+'s Shepard's checks tying each output back to a source. Posted prices run from Macro's free tier and $20/user/mo to $1,790/user/yr, three of the six are quoted, and every figure was read on the vendor's own site on October 31, 2026. This is the one category where every vendor posts a confidentiality statement: all six state that client data is not used to train their AI models, all six name SOC 2 Type II, and LegalOn, Lexis Create+ and Macro also name ISO 27001. None of the six lists Clio, MyCase, PracticePanther, Smokeball or CosmoLex as an integration; five run inside Microsoft Word, Spellbook and Macro list iManage, Macro also lists NetDocuments, and Lexis Create+ lists document management systems and DocuSign.
