The runners-up
Spellbook
Spellbook works inside Microsoft Word, suggesting clause language, flagging unusual terms, and accelerating drafting without switching platforms. It is the go-to firm-side alternative to Harvey for transactional attorneys who live in Word, with a faster entry point than an enterprise rollout. Best for mid-market firms wanting drafting help in their existing document workflow.
CoCounsel
Thomson Reuters CoCounsel (built on CaseText) drafts and reviews with the advantage of tying work back to verified legal databases. Where Harvey is a broad firm platform, CoCounsel’s strength is research-grounded output you can trace to sources. A strong choice when drafting must be anchored to authoritative legal research.
GC AI
GC AI targets in-house counsel with agentic drafting and review, Playbooks for repeatable standards, and exact-quote citations. It addresses the corporate legal side where Harvey leans firm-side. A fit for in-house teams that want drafting aligned to their own playbooks with traceable citations rather than a law-firm-oriented platform.
