Comparison
version90 vs Spellbook
This one's less a fight than a category clarification. Spellbook is genuinely good at what it is: an AI copilot that sits inside Microsoft Word and makes a lawyer faster — drafting clauses, proposing redlines, flagging risk while they type. If your day job is drafting, it's a fine tool priced like lawyer software (custom quotes, commonly reported around $99–$199+ per user per month).
But a copilot is not a filing system, a version history, a team, or a memory. When the counterparty's reply lands at 11pm, Spellbook doesn't catch it, version it, diff it, or remind anyone it exists — that's not its job. It makes the typing smarter; version90 keeps the deal under control: every version immutable, every change attributed, AI review with verified citations, the archive searchable, the whole team in — for less than one seat of the copilot.

Frequently asked questions
What's the difference between version90 and Spellbook?
Category. Spellbook is an AI copilot for lawyers inside Microsoft Word — it drafts clauses, suggests redlines and flags risks while an attorney works. version90 is a system of record for the whole negotiation: versions, tracked changes, team discussion, AI review with verified citations, and a searchable archive. One assists a lawyer's keystrokes; the other keeps the entire deal under control.
Is version90 a Spellbook alternative?
For a law firm associate drafting all day inside Word, no — Spellbook is built precisely for that person, at a per-lawyer price (commonly reported around $99–$199+ per user/month, by quote). For a business team whose problem is negotiation chaos rather than drafting speed, version90 is the fit: it manages the versions, the redlines, the counterparty email and the archive — for $100/month covering everyone.
Can I use Spellbook and version90 together?
Yes, and it's coherent: your outside counsel can draft in Word with whatever copilot they like, while version90 remains the system of record — every version they send is preserved, diffed, AI-reviewed and archived. version90 doesn't care which tool wrote the words; it cares that nothing about the negotiation gets lost.
Why does version90 cost less than one Spellbook seat?
Different economics. Per-lawyer copilots price against a lawyer's billable hour, so ~$150/user/month clears easily. version90 prices against what a small business can pay every month without a budget meeting: $100 for the whole organization, metering work rather than people.
