Harvey vs Spellbook: Enterprise Platform or Word Add-In?
Harvey and Spellbook are not two versions of the same product. Harvey is a legal AI platform for large firms and in-house departments, covering research, drafting, document review at volume and custom agents, and it is sold only through a demo. Spellbook is a contract drafting and review assistant built around a Microsoft Word add-in, with a multi-document agent on top, and you can start a 7-day free trial without talking to anyone. Both overlap on one job, drafting and redlining contracts in Word, and both answer the price question the same way: our directory lists each as "pricing on request", and neither publishes a rate card as of September 23, 2026. If your work is transactional and lives in Word, Spellbook is the narrower, easier tool to evaluate. If you need research, bulk document review and firm-wide workflows under one contract, Harvey is the category you are shopping in, and the contract review piece is one part of it.
We don't sell either tool, or a third one, and no vendor pays to influence this page. Everything below was checked against each vendor's own live pages on September 23, 2026. This is software evaluation, not legal advice.
What is each product actually built to do?
Harvey describes itself as the operating system for legal and professional services. Its product navigation lists Assistant, Agents, Vault (store and bulk-analyze documents), Knowledge (research across legal, regulatory and tax questions), Spaces (shared work with outside teams) and workflows. In its March 25, 2026 funding announcement, Harvey reported more than 100,000 lawyers across 1,300 organizations, a majority of the AmLaw 100 as partners, over 500 in-house legal teams, and more than 25,000 custom agents running on the platform. That round raised $200 million at an $11 billion valuation. Contract drafting is one of many things Harvey does.
Spellbook does one thing and goes deep on it. Its pricing page sells a single "Spellbook Suite": a Word add-in with Review, Draft, Ask, Benchmarks and Playbooks, plus Associate, which Spellbook calls an AI agent that works through multi-document legal matters. It also lists early access to a newer product it calls Autonomous Contract Management. The pricing page says 5,000 legal teams use it. When Spellbook announced its $50 million Series B in October 2025, it said it began by selling to solo and small firms but that half its revenue now comes from large firms and enterprises.
So the honest framing is a platform versus a specialist. The overlap is real, but it is one slice of Harvey and nearly all of Spellbook.
How do Harvey and Spellbook score side by side?
This scorecard grades what each vendor publishes and how each sells, because both can be checked. It does not grade output quality: no independent, reproducible benchmark compares the two tools' drafting or redlines, and we won't invent one. Scores are our editorial judgment, and the basis column shows the evidence so you can disagree with a score without disagreeing with the facts.
| Criterion | Harvey | Spellbook | Basis (verified 2026-09-23) |
|---|---|---|---|
| Scope of legal work | 5 | 3 | Harvey publishes research, drafting, bulk document review, agents and shared workspaces. Spellbook publishes contract review, drafting, benchmarks, playbooks and a multi-document agent, all transactional |
| Word integration | 4 | 5 | Spellbook's core product is the Word add-in. Harvey shipped a Word add-in with Ask and Edit modes in August 2025, and added Microsoft 365 Copilot and Copilot Cowork access in June 2026, but its center of gravity is the web app |
| Research depth | 5 | 2 | Harvey lists a Knowledge product for legal, regulatory and tax research. Spellbook publishes no case-law or regulatory research product; Ask and Compare work against the document and market contract data |
| Buying process | 2 | 4 | Harvey: demo request only, no trial or self-serve signup published. Spellbook: 7-day free trial without a sales call, extended trials for larger organizations, demo for pricing |
| Pricing transparency | 1 | 1 | Neither publishes a price. Spellbook states that cost is set by the number of team members on the license. Harvey publishes nothing at all |
| Ownership stability | 5 | 4 | Both are independent. Harvey raised $200M in March 2026 and is an acquirer (Hexus, January 2026). Spellbook raised a $50M Series B in October 2025 |
| Total | 22 / 30 | 19 / 30 | Different product types; read the rows, not the total |
The total says less than any single row. A transactional boutique would weight Word integration and buying process heavily and never touch the research row. A firm-wide rollout would do the opposite. Pick the two rows that match your actual bottleneck and read those.
Where does Harvey's platform scope matter?
Harvey earns its place when contract work is only part of the problem.
Research and drafting in one system. A litigation team or a mixed practice that needs research, memo drafting and document analysis under one security review gets that from Harvey's Knowledge, Assistant and Vault. Spellbook doesn't try to cover that ground.
Volume review. Vault is built to store and bulk-analyze large document sets, which is the shape of due diligence and investigations work. Spellbook's Associate handles multi-document matters, but Harvey's positioning, customer base and product list are built around volume across practice groups.
Custom agents and embedded engineering. Harvey says it has legal engineers who work alongside customers to build the agents that run their work. That is a real service, and it is also why Harvey is sold by demo: the product is partly configured per customer.
Word is covered too. It's commonly said that Harvey is web-only and Spellbook is the Word option. That was once a fair shorthand, but it no longer is. Harvey's August 2025 drafting release added a Word add-in where lawyers can ask questions about clauses, make clause-level and document-wide edits, pull precedent from Vault and run playbooks against a document. Spellbook's own Harvey comparison page still marks "Word Add-In" as a Spellbook feature Harvey lacks. Treat that row as outdated.
Where does Spellbook's Word-first focus win?
The whole product is where transactional work happens. A Word add-in runs as a task pane inside the document and can be installed by one user or deployed centrally by an administrator. For a lawyer who redlines all day, a product designed around that pane from the start usually fits more naturally than a platform that added one later. Spellbook's feature list (Review, Draft, Benchmarks, Playbooks) maps directly onto the steps of negotiating an agreement.
You can try it before anyone sells to you. Seven days is short for a contract tool, but it is enough to run three or four of your own agreements through it. Harvey offers no published equivalent. For a small team, that difference alone decides which product gets evaluated this quarter.
Market benchmarking. Spellbook's Benchmarks and Compare features compare contract terms against industry standards, and its Series B announcement describes a push toward market data by industry, deal size and jurisdiction. If "is this clause market?" is the question you ask most, that is Spellbook's home ground.
It is no longer only a small-firm tool. Some comparisons still describe Spellbook as a product for solo lawyers. Spellbook's own October 2025 statement that half its revenue comes from large firms and enterprises says otherwise. It serves both ends; it just does one kind of work.

What does each reportedly cost?
Neither vendor publishes a price, so every figure here is reported, not confirmed.
Harvey. Harvey has no pricing page; every route ends at a demo request. The most cited attributed figure comes from Artificial Lawyer's June 2025 analysis, which said "street chatter still pins Harvey's base at ~USD 1.2K / seat / year". Harvey disputed parts of that article. Metronome's pricing index, a billing-infrastructure company's tracker, lists Harvey Assistant at $12,000 to $14,400 per seat per year, and $15,600 to $16,800 for a premium bundle. Those two reported figures differ by a factor of ten. We worked through that gap, including a cross-check against Harvey's own lawyer count, in our Harvey AI pricing breakdown.
Spellbook. Spellbook's pricing page says: "Pricing is determined by the number of team members on a license," and routes buyers to a demo. Third-party estimates exist, but most are published by vendors of competing contract tools and several trace back to each other. We laid out every one with its source in our Spellbook pricing analysis.
What you can say with confidence: Spellbook is the cheaper tool to evaluate, because a free trial costs a week and a demo-only platform costs a sales cycle. Which one is cheaper to own depends entirely on your quote, your seat count and, for Harvey, which modules and content are bundled.
Which teams should shortlist which?
| If your team is... | Shortlist | Why |
|---|---|---|
| A transactional practice that drafts and negotiates in Word all day | Spellbook first | The product is built around that workflow, and a trial costs nothing but a week |
| A large firm buying one AI platform across practice groups | Harvey first | Research, volume review, agents and Word in one contract and one security review |
| An in-house team that mostly reviews commercial contracts | Both, on a pilot | Spellbook fits the daily review loop; Harvey fits if the same team also handles regulatory research |
| A litigation-heavy team | Harvey, then compare peers | Spellbook is transactional by design; research depth is the deciding row |
| A small firm that needs a budget number before any call | Neither yet | Both are quote-only. Start with tools that publish rates |
For that last row, and for anyone who wants to see what else sits near Harvey, our Harvey AI alternatives guide groups the field by product shape. You can also line tools up yourself on our comparison pages.
Whatever you shortlist, pilot it on your own matters. The ABA's Formal Opinion 512 points lawyers using generative AI to their existing duties of competence, confidentiality, communication and reasonable fees, which in practice means your own evaluation of how a tool handles client data and how much checking its output needs. A vendor comparison, including this one, can't do that part for you.
FAQ
Is Spellbook cheaper than Harvey?
There is no verified answer, because neither vendor publishes a price. Spellbook bases its quote on the number of team members on the license. Harvey's reported figures range from about $1,200 to $14,400 per seat per year depending on the source, and neither end is confirmed by Harvey. What is certain is that Spellbook is cheaper to evaluate: it offers a 7-day free trial, while Harvey starts with a demo.
Does Harvey work inside Microsoft Word?
Yes. Harvey announced a Word add-in on August 26, 2025, with Ask and Edit modes, clause-level and document-wide edits, access to precedent in Vault, and playbook runs. In June 2026 it also became available as an agent inside Microsoft 365 Copilot. Pages that describe Harvey as web-only are out of date.
Can a small firm buy Harvey or Spellbook?
Spellbook, yes: its pricing page says it supports teams of all sizes, from individuals up, and the trial is self-serve. Harvey publishes no seat minimum, and in a statement included in Artificial Lawyer's June 2025 piece it said it has "a considerable number of mid-sized law firms and smaller inhouse teams." Its sales motion is still built around enterprise buyers, so expect a longer process.
Is Spellbook a Harvey alternative?
Only for contract work. If what you need from Harvey is drafting and redlining agreements in Word, Spellbook covers that job and is easier to trial. If you need legal research, bulk document review or firm-wide agents, Spellbook doesn't try to replace those, and a broader platform is the right comparison.
