AI legal that fits in Word — the right product for the right buyer
Spellbook is the practical AI contract tool for solo lawyers, in-house counsel, and small-to-mid law firms. Drafts and reviews inside Word with no workflow change. Less ambitious than Harvey, more useful for most lawyers.
Spellbook's product insight is the opposite of Harvey's: most lawyers don't need an AI legal research platform, they need their existing Word workflow to be 50% faster. Spellbook ships as a Word add-in that drafts clauses, redlines counterparty contracts, and enforces playbook positions inline. The 2,500+ law-firm customer base reflects the reality: for solo lawyers, in-house teams, and small-to-mid firms, this is the right shape of AI tool.
Versus Harvey, the positioning is clear and complementary: Harvey targets AmLaw 100 firms with complex DMS workflows and significant litigation practices; Spellbook targets the long tail of contract-focused lawyers who live in Word. Both can be right for the same firm in different practice groups. The Pro tier ($179/user/mo) prices below Harvey but well above general-purpose AI ($20/mo Claude Pro), reflecting the specialized clause library and playbook enforcement.
The weakness is depth. Spellbook is a contract-drafting and review tool — it's not a research platform, it's not a litigation tool, and the AI capabilities outside contract work are thinner. Buy Spellbook for any lawyer or in-house team that drafts or reviews contracts daily. Stay with Harvey for AmLaw 100 firms with complex DMS and research workflows. Skip if your practice doesn't involve significant contract work.

Before you buy Spellbook
Vendors don't tell you about their competitors. We do — with verdicts attached when we have them.
What Spellbook actually costs
Sticker price isn't the real cost. We add implementation, training, and a probability-weighted lock-in penalty.
When to negotiate Spellbook
Vendor sales pressure is non-uniform — quarter-close, year-end, and post-funding-round are your high-leverage windows.
Strong negotiation window. Reps will push for end-of-quarter signature. Don't move first — let them initiate the discount. Target 15-30% off list plus negotiated terms.
Take this to your sales call
10 questions vendor sales teams steer around — generated from Spellbook's pricing tier, lock-in profile, and editorial verdict.
- 1PRICINGSpellbook is professional-tier on the public site. What's the discount path for small-sized teams committing annually vs. monthly?
- 2PRICINGWhat overages or seat-overflow charges should we plan for? Show me the worst-case bill if our usage grows 2x in year 1.
- 3CONTRACTAuto-renewal: how many days notice is required to terminate, and what happens if we miss the window? Will you commit to a renewal-reminder email at 90 and 60 days?
- 4MIGRATIONData export: what's the complete spec — format, frequency, and what data does the export NOT include? After contract end, how long do we have read-only access?
- 5MIGRATIONImplementation runs 1–3 days. Who from your team is included by default, and who do we add at additional cost? Is a CSM assigned?
- 6FITSpellbook is best for: Solo lawyers, in-house legal teams, and small-to-mid law firms who draft and redline contracts daily and live in Word.. We're [describe your situation]. Walk me through the failure modes if our profile doesn't match.
- 7FITConnect us with 2-3 reference customers at our company size in your industry — not the case-study list, customers who've been live for 18+ months and have churned at least one tool from your stack.
- 8INTEGRATIONSpellbook lists 2 integrations including Microsoft Word, iManage. Which of OUR existing tools — bring our list — have you confirmed shipping integration with versus "on roadmap"? Show me the actual status.
- 9VENDORTrack record over the last 18 months: any pricing model changes, executive departures, layoffs, M&A activity, or material customer churn we should know about?
- 10VENDORIf you're acquired or shut down, what's the contractual continuity — source-code escrow, data portability, transition period? Show me the actual clause.
What to actually test in the demo
Vendor sales teams script demos to maximize close rate. Here's what they'd rather you not test — derived from Spellbook's lock-in profile and editorial verdict.
- 1PERFORMANCEBring YOUR data, not their demo data. Insist on running the demo workflow against a sample of your real records, files, or queries. If they refuse — that's a signal.
- 2PERFORMANCESpellbook demo will be built around the happy path. Ask: "Show me what happens when [the most common failure mode in our context]" — make them improvise.
- 3EDGE CASESPush the limits live: largest dataset, longest workflow, most users concurrent. Vendors prep demos for medium loads — your real-world usage might 10x what they show.
- 4EDGE CASESMobile and offline behavior: how does Spellbook degrade on slow connections, on iPad, in airplane mode? Test in the demo if your team uses these surfaces.
- 5PRICINGModel your worst-case bill: 2x the seats, 3x the usage. Show the exact dollar figure on screen during the demo. Refuse "we'll get back to you" — get the math live.
- 6INTEGRATIONVendors love their integration logo wall. Test the actual depth: pick the 2-3 (Microsoft Word, iManage-style) integrations you depend on most, and ask the rep to demo a real two-way data sync, not a marketing screenshot.
- 7INTEGRATIONAPI and webhook reality check: rate limits, payload size limits, retry behavior, auth refresh handling. Ask for actual API docs in the demo, not "we'll send those."
- 8MIGRATIONDemo the full data export workflow. Even with low lock-in, you want to see how clean the exit looks before signing.
- 9SUPPORTSubmit a real support ticket DURING the demo. Use the actual support channel customers use, not the rep's email. Time the response. This is your most honest data point about post-sale reality.
- 10SUPPORTAsk to be connected with a customer in the demo who you can email TODAY (not "we'll arrange a reference call next week"). The vendor's confidence in their references is a tell.
