4 things LexDraft does that Spellbook doesn't
Shipped in 2026 — the moats that turned the Spellbook comparison upside-down. All live in the LexDraft free tier.
Word-level diffs, not whole-paragraph replacement
Spellbook replaces the entire paragraph when it suggests a change — your formatting, defined-term capitalization, and surrounding clauses all get rewritten. LexDraft's surgical-edit engine identifies the exact 3-12 word span that needs to change and applies a tracked change scoped only to that span.
4 attorney-authored playbooks built in
Mutual NDA, SaaS MSA, Data Processing Addendum, Services Agreement — each with specific rules ("Is the LOL capped at 12 months of fees?", "Is there a survival clause for confidentiality?") that LexDraft injects into the review prompt. Free tier. Spellbook gates equivalent playbooks behind a Premium tier upgrade.
Instant defined-term + cross-reference scans (no AI)
Regex-based checks that run in single-digit milliseconds — catches "Customer Data" used 3 times but never defined, or "Section 5.4" that doesn't exist after an edit. Spellbook does AI review but no fast-path consistency scanning, so these errors slip through.
Case-law citations verified against CourtListener
When LexDraft's Assistant cites case law, every citation gets cross-checked against the CourtListener database (4.2M US opinions) and tagged ✓ verified or ⚠ unverified before you see it. Spellbook's drafting assistance does not include case-law verification — the #1 hallucination risk that's stopped lawyers from trusting AI tools.
Why Legal Professionals Choose LexDraft Over Spellbook
1. Start Free, No Credit Card Required
LexDraft's free plan (2,000 words/month) lets you draft 3-5 simple contracts per month with zero commitment. Spellbook requires payment from day one. Try LexDraft risk-free before upgrading.
2. Works Natively in Microsoft Word (No Separate Platform)
LexDraft is a lightweight Word add-in that works exactly where you already draft. No switching between apps, no browser windows, no clunky interfaces. Generate, edit, and save—all in Word.
3. Purpose-Built for Legal Drafting (Not a Research Platform)
LexDraft focuses exclusively on contract drafting and review. You don't pay for unused research features or Westlaw/Lexis integration you might not need. Keep your workflow simple and costs low.
4. 4x Lower Pricing for Professional Features
LexDraft Professional ($99/mo) offers AI drafting, review, and redline—features Spellbook charges $400+/mo for. Same capabilities, 1/4 the price.
Testimonial: Switching from Spellbook to LexDraft
"We've been using Spellbook for 2 years, but the pricing never made sense for a 4-person firm. At $400/month, we were paying $4,800/year for a tool we used maybe 20 hours per month. Switched to LexDraft Professional at $99/month and haven't looked back. Same Word integration, faster drafting, and we're saving $3,600/year. The AI is just as good."
