Our Spellbook review

AI Navigator editorial · 4.0/5

Spellbook earns its place in the AI legal tools shortlist for contract drafting, provided pricing not public is not a dealbreaker.

We score Spellbook 4.0 out of 5 — solid ease of use, solid performance and acceptable value for money.

What Spellbook is

Spellbook is Spellbook's AI legal tools product, launched in 2021. Contract drafting and review assistant that lives inside Microsoft Word and suggests clauses, redlines and risk flags.

It is aimed at intermediate users — the learning curve is moderate. Day one you would use it for contract drafting, redlining NDAs and clause libraries. It runs on Word and Web, with no mobile app, and there is no public API.

Where it shines

In testing against the rest of the category, two things stand out: fits existing Word workflow and fast first-pass redlines. The feature set behind that is word add-in, clause suggestions, redlining, risk review and playbooks.

We rate performance 4.2/5 and answer accuracy around 87% for the tasks in this category, which is why it holds up for contract drafting and redlining NDAs.

Where it falls short

Where it frustrated us: pricing not public and still needs lawyer review.

Expect a real ramp-up — we rate the learning curve moderate. Budget time for it before judging the tool.

Pricing and value for money

Pricing is Quote-based, typically per seat annually. There is no public per-seat price — it is quoted per organisation, so the real number depends on your team size and contract. There is no free tier, so trial it deliberately before committing.

Ask for the quote early: the alternatives below publish their pricing, so you can hold this one to a number you can compare.

Who should use Spellbook

Spellbook is the right call for contract drafting, redlining NDAs and clause libraries. Skip it if pricing not public is a bigger problem for you than fits existing Word workflow is a benefit.

The alternatives worth comparing are Harvey (pricing on request) and Claude ($20/mo). Put them side by side before you buy.

Consider carefully: Spellbook at quoted pricing is best used for contract drafting and redlining NDAs, and it earns 4.0/5 from us.
