In their own words

BlackBoiler

BlackBoiler reviews contracts in Microsoft Word by applying an organization’s playbook, previous redlines, approved wording, and examples. It creates first-pass tracked changes and comments; reviewers then accept, modify, reject, escalate, or negotiate each suggestion. Veris provides conversational access to playbooks and contract language within Word. The service covers recurring agreements such as NDAs, service agreements, and subcontracts, plus construction prime contracts, subcontracts, and professional services agreements using AIA, ConsensusDocs, and EJCDC forms. BlackBoiler is aimed at in-house legal teams, law firms, contract managers, and construction legal, commercial, procurement, and project teams. It concentrates on pre-execution review and redlining, while an existing CLM can handle intake, approvals, signatures, and the broader lifecycle. Platforms are web and API. Starter costs $1,250/user/year, Pro costs $3,000/user/year, Enterprise pricing is custom, and a seven-day trial requires a credit card.

ClauseShift

ClauseShift is a cloud-based tool for reviewing contracts. It extracts clauses, identifies risks, and compares terms. It is available on Android, web, and Windows. The free plan includes 3 reviews per month and 3 questions per day. Lite costs $9 a month, with 10 reviews per month and 20 questions per day; monthly or annual billing is available, and annual billing saves two months. Pro costs $29 a month and includes unlimited reviews and 100 questions per day, also with monthly or annual billing and two months saved annually. For occasional reviews, Pay as you go costs $1.50, with no subscription and a two-model cross-check. Packs of 5, 25, or 50 reviews reduce the per-review price to $0.50. The service is delivered in the cloud, so its listed platform options are Android, web, and Windows.
