Our recommendation
Pick Harvey if you are at an Am Law 200 firm or large in-house team that needs deep diligence, litigation research, and verified-citation discipline at enterprise governance. Pick Spellbook if you are solo, small-firm, or in-house and your work centers on drafting and reviewing contracts inside Microsoft Word. Many in-house teams adopt both — Spellbook for daily drafting, Harvey (or Vault) for big projects.
How to choose the right platform
Choosing between automation platforms isn't just about features — it's about matching the tool to your team's technical capability, budget constraints, and specific use cases. The "best" platform is the one your team will actually use consistently.
Decision framework
Ask these questions before committing to a platform:
- Who will build the automations? Non-technical users need visual builders (Zapier, Make). Developers prefer code-first tools (n8n, custom).
- How complex are your workflows? Simple A→B integrations work on any platform. Multi-step, branching workflows need Make or n8n.
- Do you need AI/LLM capabilities? Only n8n has native LangChain integration for AI agent workflows.
- What's your data sensitivity? If data must stay on your servers, only self-hosted options (n8n) qualify.
Migration considerations
Switching platforms after building 100+ workflows is painful. Factor in migration cost when choosing — it's worth paying slightly more upfront for the right platform than saving money now and facing a 6-month migration later.
Sources: Assessments draw on vendor documentation, public user reviews (G2, Capterra), community forums, and NextAutomation's hands-on experience building on these platforms.
Frequently Asked Questions
For deep diligence, litigation research, and firm-wide knowledge work at large firms — yes. For day-to-day contract drafting and review in Microsoft Word — Spellbook is genuinely the better fit and dramatically cheaper. They overlap less than the marketing makes it seem.
Harvey does not publish pricing. Reported deals run from roughly $500K/year at the low end to multiple millions for large firm-wide rollouts with Vault and custom workflows. Spellbook, by contrast, lists $159-$329 per seat per month publicly.
Practically, no. Harvey sells enterprise contracts with significant minimums and 8-16 week implementations. Solo and small-firm lawyers are better served by Spellbook, which is self-serve and works on day one. Some lawyers also use Claude or ChatGPT directly for general drafting tasks.
Not really — Spellbook is built for contract drafting and review, not for diligence of large data rooms. If M&A diligence is a major part of your practice, Harvey (with Vault) or a purpose-built tool like Kira / Luminance is a better fit.
No, both publicly state they do not train models on customer data. Harvey offers zero-data-retention configurations. Spellbook is SOC 2 Type II and contractually does not use customer documents for training. Always confirm the current DPA before signing.
