Spellbook vs Harvey: Pricing, Seat Minimums and Which Firm Each Fits
Spellbook vs Harvey on price, seat minimums and the work each is built for. Harvey's reported 20 to 25 seat floor settles it for most firms under 20 lawyers.
Spellbook is the contract drafting tool a small or mid-size transactional practice can actually buy. Harvey is the enterprise platform large firms buy for research and litigation. Neither publishes a price. On what buyers report, a Spellbook seat runs somewhere between $99 and $500 a month with no stated minimum, while Harvey runs about $1,200 per seat per month with a floor of 20 to 25 seats, which puts Harvey's entry contract near $288,000 a year. Under about 20 lawyers, that floor decides the question before the features do.
A disclosure before the detail. Most pages ranking for this comparison are written by legal AI vendors, including Spellbook itself. So is this one. CaseClerk does one narrower job than either tool: it reads every document in a matter and answers questions that name the source document, at a price we publish. We have kept the Spellbook and Harvey facts to what each company says on its own site, and labeled everything else as reported.
Spellbook vs Harvey pricing
Spellbook's pricing page says pricing is custom and "structured around the number of team members on your license", offers a 7 day free trial, and mentions discounts for teams over 10. Harvey offers nothing on its site but a demo request. Every dollar figure below comes from buyer reports and review sites, and they disagree:
| Spellbook | Harvey | |
|---|---|---|
| Published price | None. Pricing page says custom, set by the number of team members on the license | None. harvey.ai offers a demo request only |
| Free trial | 7 days, stated on its pricing page | No self serve trial |
| Reported seat price | Anywhere from $99 to about $500 per seat per month, depending on the source | About $1,200 per seat per month for the core product, with a reduced tier near $399 reported |
| Reported seat minimum | None stated. Discounts mentioned for teams over 10 | Roughly 20 to 25 seats |
| Implied entry cost | A single seat, if you buy one | About $288,000 a year at 20 seats |
| How you buy | Trial, then a quote. Solos and small firms can start directly | Enterprise sales process and procurement |
The Spellbook range is wide because the published estimates contradict each other. We walk through where each one comes from in what a Spellbook seat really costs. The Harvey numbers are more consistent, and the one on record from Harvey itself is thin: "a few hundred dollars per seat" for large companies, with a high employee floor. The full sourcing is on our Harvey AI pricing and seat minimum page.
Spellbook vs Harvey cost at four firm sizes
Here is the arithmetic, using the reported figures and Harvey's reported minimum. It is a way to size the conversation before a demo, not a quote. First quotes in this market reportedly come down a long way in negotiation.
| Firm size | Spellbook, at $200 to $500 per seat per month (reported range) | Harvey, at $1,200 per seat per month with a 20 seat floor (reported) |
|---|---|---|
| 1 lawyer | $2,400 to $6,000 a year | Not realistically available |
| 5 lawyers | $12,000 to $30,000 a year | About $288,000 a year, paying for 15 empty seats |
| 15 lawyers | $36,000 to $90,000 a year | About $288,000 a year, paying for 5 empty seats |
| 30 lawyers | $72,000 to $180,000 a year | About $432,000 a year |
The seat floor is the whole story for small firms. A 5 lawyer practice looking at Harvey is not choosing between two products, it is choosing between a tool it can license for its lawyers and a contract sized for a firm four times its size. Above 30 lawyers the question becomes the work itself.
Is Spellbook better than Harvey for contract review?
For drafting and redlining contracts in Word, yes, for most firms. Spellbook is built around that job: its Word add-in reviews a draft, suggests redlines, benchmarks terms against market data and applies a firm's saved playbooks. Harvey is broader and deeper on research, litigation and large document analysis, and it is sold to firms that want one platform for all of it.
| Job | Spellbook | Harvey |
|---|---|---|
| Drafting and redlining contracts in Word | Its core product: Review, Draft, Ask, Benchmarks and Playbooks inside a Word add-in | Available, but drafting is not what Harvey is bought for |
| Market standard checks on clauses | Benchmarks compares terms against market data | Not its focus |
| Legal research and litigation work | Not its focus | Its core: research, document analysis, brief and argument review |
| Multi-document matters | Associate, an agent that works through multi-document matters with your oversight | Vault and workflows for large document sets |
| Security | SOC 2 Type II, GDPR and CCPA, per its own page | SOC 2 Type II, ISO 27001, 27701 and 42001, per its own site |
| Who it says it serves | 5,000 legal teams, firm and in-house, commercial law | 2,400+ legal organizations, large firms and corporate legal teams |
Spellbook also argues that Harvey takes longer to roll out across a large team. That is a vendor claim about a competitor, so weigh it as one, but it matches the difference in how the two are sold: one starts with a trial, the other with procurement.
Which is cheaper, Spellbook or Harvey?
Spellbook, by a wide margin at any firm under about 30 lawyers. The reported per seat price is lower, but the bigger difference is that Spellbook states no seat minimum, so a firm pays for the lawyers who use it. Harvey's reported 20 to 25 seat floor means a 10 lawyer firm pays for at least twice the seats it needs.
Who should choose Spellbook
A transactional practice of 1 to 30 lawyers doing commercial contracts, M&A support, leases, vendor agreements and NDAs, where the lawyers live in Word and the bottleneck is turning drafts and markups faster. Start the 7 day trial on a real agreement from your own files, ask for a written quote for your exact seat count, and ask whether the price holds at renewal.
One thing neither tool handles is what happens after signing. A vendor agreement that requires the other side to carry insurance still needs someone to collect and chase the certificates of insurance it calls for, and that is a separate system from anything that drafts the contract.
Who should choose Harvey
A firm or legal department large enough to clear the seat minimum comfortably, doing litigation, regulatory and research heavy work across practice groups, with an IT and procurement team to run an enterprise rollout. If you are in that group, compare Harvey against Legora, which reportedly starts at a 10 seat floor. We priced that matchup in Harvey vs Legora pricing.
Is there a Spellbook or Harvey alternative with a published price?
Yes, if your real job is reading documents rather than drafting them. A lot of what firms want from a Harvey demo turns out to be simple: put a deal file or a production in one place, ask questions across all of it, and see which document each answer came from. That is what CaseClerk does. It holds up to 1,000 documents per case across 18 file formats and names the source document in every answer. Prices are published: $99, $249 or $499 a month for the account, not per user, with a quoted Enterprise tier above that. It does not draft or redline in Word, so it does not replace Spellbook for drafting work.
For transactional teams, our AI contract review software page shows how that works on a deal file: which agreements contain a change of control clause, where the indemnity caps differ, which schedules are missing. If you are shortlisting more broadly, Harvey AI alternatives for small law firms puts the tools a 1 to 20 lawyer firm can buy side by side, with the prices each vendor posts.
Questions to ask either vendor before you sign
- What is the seat minimum, in writing? For Harvey this sets the whole contract. For Spellbook, confirm there is none for your size.
- Does the price hold at renewal? Ask for a cap on the renewal increase, especially on a first year discount.
- Is any usage billed on top of seats? Agent features across the category are moving to credits or consumption charges.
- What happens to our documents? Ask about training, retention and deletion on exit, and get it in the contract, not the sales deck.
- Who is on the license? Paralegals and contract managers count as seats under per user pricing. Price the team you will actually run.
If you would rather test the reading job before any of those calls, upload one real matter to CaseClerk: 25 pages, up to 5 files, no card. You will know in an afternoon whether the problem you are pricing Harvey or Spellbook to solve is drafting or reading.
