Spellbook
Officially listedA Word-native AI contract review assistant built for transactional lawyers and in-house teams.
Spellbook
Spellbook (formerly Rally Legal) is an AI copilot deeply customized for transactional lawyers and corporate legal teams, running ingeniously as a native Microsoft Word plugin. The design means legal professionals never have to leave the drafting environment they know best — powerful AI sits seamlessly in the document sidebar, transforming the tedious traditional workflow of contract drafting and review.
Core Capabilities
- AI contract review and redlines: Automatically deep-scans the open contract, rigorously checking it against your configured 'Playbooks' (custom rule sets) to precisely identify risky clauses, then generates suggested edits and professional redline comments in one click.
- Smart drafting and precedent text: Lawyers enter natural-language instructions (for example, 'draft a non-compete clause for executives'), and the AI generates legally sound clauses from scratch or intelligently pulls from your preferred precedent library.
- Market-standard benchmarking: Innovatively cross-references current contract clauses against a vast database of thousands of industry-standard agreements, helping lawyers quickly confirm whether existing wording meets industry 'market standard.'
- Advanced multi-document agent: The built-in Spellbook Associate breaks the single-document limit, operating as a high-level AI agent on complex multi-document workflows and efficiently running cross-file information review and key-clause comparisons.
- In-document legal Q&A: Lawyers can ask specific questions about the long, complex contract they are reading; the AI not only extracts answers fast but attaches precise in-document citation sources.
Use Cases The perfect partner for standardized legal documents such as commercial agreements, M&A papers, and employment contracts — especially suited to transactional lawyers, in-house legal teams, and small-to-mid-size law firms urgently seeking higher per-person output.
Unique Advantages Unlike Harvey AI's multi-thousand-dollar entry point or CoCounsel's litigation-research focus, Spellbook is obsessively focused on contract drafting. Its biggest killer feature is 'zero-friction workflow' integration plus a SOC 2 Type II certified 'zero data retention' policy, ensuring a firm's core secrets are never used to train external models.
Editor's Verdict Spellbook targets the most time-consuming, most mechanical part of legal work — contract review — and delivers a perfect answer in the form lawyers cannot resist: a Word plugin. Google Docs is not supported, but within its contract-drafting vertical, the extremely low learning cost and immediately visible efficiency gains make it easily the best AI productivity choice for transaction lawyers today.

FAQ
Is Spellbook free?
Spellbook is not a free tool; it mainly uses a custom quote model based on team size and feature needs. However, it offers a 7-day free trial for new users to experience.
What can Spellbook be used for?
Spellbook mainly helps lawyers draft and review contracts inside Microsoft Word. It automatically identifies risky clauses, generates redline comments, drafts new language, and benchmarks against market standards.
How does Spellbook differ from Harvey AI?
Harvey AI is expensive and aimed at the comprehensive needs of large law firms, while Spellbook focuses on contract work for transactional lawyers, running as a Word plugin at a friendlier price with a lower learning curve.
Does Spellbook support use in Google Docs?
Not currently. Spellbook is a native plugin built specifically for Microsoft Word and cannot run in Google Docs or other web-based document editors.
Is it safe to process clients' confidential files with Spellbook?
Very safe. Spellbook holds SOC 2 Type II certification and enforces a strict 'zero data retention' policy, guaranteeing it never uses clients' confidential legal documents to train global AI models.
Is Spellbook suitable for litigators?
Not really. Spellbook is designed for transactional lawyers handling commercial agreements, M&A documents, and similar paperwork. The case management and case-law research litigators need most are not its core strengths.
