Spellbook Pricing: How a Small Firm Should Read the Quote

Spellbook does not publish a price: a small firm gets a quote based on the number of licensed team members, with a seven-day free trial available. Set it beside Microsoft Copilot Business ($21 per user a month on an annual term) and Gavel Exec ($160 monthly or $1,740 a year per user), line by line, then test all three on one NDA.

So the useful skill is reading the quote, not guessing the number. Spellbook's pricing page says nothing about contract length, billing period, minimum seats or cancellation, which are the lines where small firms tend to lose money. Demand those lines in writing, set the three tools side by side, place the quote on a price ladder, and run one NDA through all three before you sign.

What Spellbook publishes and what it keeps for the quote

Everything on Spellbook's pricing page that bears on cost fits in a short list. Pricing is determined by the number of team members on a licence, and a personalised figure requires a demo. Lawyers and legal teams can try it free for seven days, with extended trials possible for larger organisations. A law firm plan lists the Spellbook Suite (a Word add-in plus Associate, which it describes as a multi-document agent), group training, online support and, for teams over ten, dedicated support. In-house plans add a playbook build service.

The product itself, per its home page: Review redlines contracts and flags risks, Draft writes from scratch or from saved libraries, Ask answers questions, Compare checks against industry standards, Playbooks turn the firm's standards into automated checklists, and Associate works across several documents. It lists Word and Google Docs as places it works, plus integrations with Slack, OneDrive, Dropbox, SharePoint, Google Drive and iManage. A separate product called ACM is offered as early access, so keep it out of the quote unless you ask for it.

What the page does not say is the cost-relevant part: price per seat, tier names, billing period, minimum seats, contract length, cancellation, and whether the Associate agent or any integration is priced separately. Treat each as a line to fill in. Also note the support tiers: dedicated support begins above ten users, so a firm of four will be on group sessions and online support unless the quote says otherwise.

The quote line by line, beside Gavel Exec and Copilot

Here are the lines every quote for a Word-based AI tool should settle, with what each vendor publishes. Blank cells in Spellbook's column are your questions. Microsoft's figures come from its Copilot Business page as read on 4 November 2026. Microsoft now calls its app Microsoft Copilot, though the product page still says Microsoft 365 Copilot Business.

Two cells deserve a second look. Gavel's 1,000 queries a month is a cap, and its Exec pricing page says a paid plan includes "1,000 completions per month" without saying what happens after that, so ask. Microsoft's trial is the opposite problem: it converts to a paid subscription on its own, so put the end date in your calendar. Microsoft also bills some advanced AI features by usage on top of the seat, so ask which ones and whether they are switched on by default. Spellbook's seven days is the tightest clock of the three, which is why the trial plan further down matters.

For a feature-by-feature view of the products, the comparison of Spellbook and Gavel Exec for lawyers and Spellbook against Copilot for drafting in Word go deeper than this tutorial does. The question here is narrower: what you pay and what you must get in writing.

A price ladder to place the quote on

Even without Spellbook's number you can say where a quote should land. Per user per year, the listed prices are $252 for Copilot Business ($216 on the promotional $18), $1,740 for Gavel Exec billed annually and $1,920 for Gavel Exec billed monthly. For a three-lawyer firm that is $756, $5,220 and $5,760 a year. When Spellbook's figure arrives, divide it by the seat count and by twelve, then place it on the ladder. If it sits near the top rung, you are paying a Gavel-sized price and should ask what extra it buys. If it sits far above, ask what is bundled in.

The per-year figure hides the real question, which is what each reviewed document costs. Cost per document is the monthly seat price divided by documents reviewed per user per month. The third column uses a placeholder $200 seat price, not a Spellbook quote:

Turn that into minutes. At a fee-earner cost of $200 an hour, a minute is worth about $3.33. At 20 documents a month, Gavel Exec on an annual plan has to save about 2.2 minutes per document to break even, and the placeholder $200 seat needs 3 minutes. Copilot needs under half a minute. At 5 documents a month, the same Gavel seat needs nearly 9 minutes saved on each. The tool you should buy depends heavily on volume, and a firm reviewing five NDAs a month per lawyer is paying for a lot of idle capacity on any of the premium seats. As with all time-saving sums, the minutes only count if they turn into billed work, faster turnaround that wins a client, or work you no longer have to hire for.

Two seat-count tricks affect the ladder. Buy only for people who will review contracts weekly; a seat for the litigator who sees one NDA a year is waste. And ask whether seats can be added mid-term at the same rate, because a quote that is cheap for three seats may step up at ten, which is about where Spellbook's dedicated support and Gavel's team pricing both begin.

A realistic mistake: a five-lawyer firm accepts a per-seat price that looks lower when five seats are bought together, then finds that only two lawyers review contracts regularly. At the placeholder $200 a seat, the two working seats cost $4,800 a year and the three idle ones cost $7,200. The saving on the headline rate was real; the waste was bigger. The fix is to size the quote to the people who will use it weekly, and to ask for a price at that number.

One NDA, three tools: a test that settles the argument

A demo on the vendor's own sample contract proves little. Write one mutual NDA of about 1,800 words with six problems planted in it, and run the same document through each tool inside the same trial window. Use made-up party names; never a client's real agreement.

1. An indemnity buried inside the confidentiality clause that binds only one party.
2. A confidentiality term of ten years where your standard is three.
3. No carve-out for information the recipient already knew or developed independently.
4. A non-solicitation clause that does not belong in an NDA.
5. A governing-law clause that names one place and a courts clause that names another.
6. A definition of confidential information covering "all information", with no marking requirement.

Give every tool the same instructions. Spellbook and Gavel Exec both advertise playbooks, so load your rules there. Copilot has no playbook feature in the pages I read, so paste the rules into the prompt.

Our NDA rules:
1. Obligations bind both parties equally; no one-sided indemnity.
2. Confidentiality lasts three years from disclosure.
3. Excludes information already known, public, or independently developed.
4. No non-solicitation or exclusivity terms.
5. Governing law and courts must match.
6. Confidential information must be marked or identified as confidential.

Review the attached mutual NDA against the six rules. For each rule, say
pass or fail, quote the clause, and propose replacement wording as a
tracked change. Do not change anything that already passes.

Score each tool on the same grid. This filled-in sheet uses invented results to show how to read it:

Look at what the sheet says. Tool Y found one fewer issue than Tool X but raised no false alarms and was quickest, which for a busy small firm may be the better product. Tool Z found the fewest, raised three false alarms and asked to send text elsewhere, so it fails on both quality and data handling whatever its price. The sheet tells you which price to negotiate: the quote for the tool that passed, not the cheapest.

Here is one illustrative output line and what to do with it. The tool reports: "Rule 2: fail. Clause 9 sets confidentiality for ten years from the effective date. Proposed: replace 'ten years' with 'three years from the date of disclosure'." The wording is right for your rule, but a lawyer must still decide two things the tool cannot: whether trade secrets need a longer tail than three years, and whether this counterparty deserves the standard at all. A tool that applies the playbook is saving typing and checking, not judgement.

Data handling and term: what belongs in the order form

Client confidentiality makes this the part a partner should read before the price. The published statements are encouraging, but they are marketing, not contract terms. Spellbook says its zero-data-retention agreements mean its AI providers "never learn from, train on, or store your data", and it lists SOC 2 Type II. Gavel's Exec page makes no specific data claims and sends security questions to a demo. For Microsoft, the Copilot Business page says prompts and responses are not used to train the underlying large language models, and Copilot in Word works within Word and your Microsoft 365 content without connecting to outside tools.

Whichever tool wins the test, get these into the order form or an attached data processing schedule:

1. The zero-retention commitment, in the vendor's own words, covering every AI provider it uses.
2. A named list of sub-processors, with notice of changes.
3. A statement that your documents and prompts are not used to train any model.
4. Where documents are processed and stored, and how long the vendor keeps them.
5. Deletion on request and at termination, with a date by which it is complete.
6. The vendor's security report (the SOC 2 Type II report, under a confidentiality agreement) for your insurer or a client who asks.
7. Notification of any breach, and by when.

Then the term, which Spellbook's page does not describe at all:

1. Contract length, whether it renews automatically, and how much notice cancels it.
2. Whether the per-seat price is held at renewal or reset.
3. Whether you can reduce seats at renewal, and add seats mid-term at the same rate.
4. What the trial converts into, and on what date, if you do nothing.
5. Whether the Associate agent, any integration or a playbook build service is a separate charge.
6. A refund or exit right if the tool fails your test in the first month.

The wider supplier checks, covering supervision and data, are in the two-week trial scorecard for lawyers and the small-firm test of Microsoft Copilot in Word and Outlook.

Seven days is short: a plan for the trial

Spellbook's trial is seven days and Gavel Exec's is 25 queries per user, so neither gives you a leisurely month. Prepare before you start the clock.

• Before day one. Write the six-issue NDA and the six rules. Decide who will score. Put the Microsoft trial end date in your calendar so it does not roll into a paid term.
• Day one. Install, then run the NDA through Spellbook. Record the grid. Do the same on Gavel's 25 free queries and on Copilot.
• Day two. Run two or three closed, de-identified agreements of different types, such as a supply contract and an engagement letter, to see whether the playbook rules carry across.
• Day three. Ask the data questions above, in writing, and see how fast and how specifically each vendor answers.
• Day four. Request the quote with the lines from the table. Ask for a longer trial if one is needed; Spellbook says extended trials may be available for larger organisations.
• Days five to seven. Compare quotes against the ladder, read the term lines and decide.

Which seat for which kind of small firm

• Reviews contracts every week and wants firm-specific rules applied. Spellbook or Gavel Exec. Both document playbooks and benchmarking, so choose on the test score and the quote, not the feature list.
• Mostly drafts and summarises, reviews contracts now and then. Copilot Business may be enough at a fraction of the price, provided you paste the rules each time and check every answer. It is also the simplest to explain to a client who objects to a new processor, since it stays inside your Microsoft tenant.
• Under ten lawyers. You are below the line where Spellbook's dedicated support and Gavel's team pricing begin. Ask what support and discount you do get, and do not assume the large-firm terms apply.
• A mixed firm. Buy two or three premium seats for the contract specialists and give everyone else Copilot, then compare the per-document figures after a quarter.

A phased route suits many small firms. Start with Copilot Business for everyone who drafts and keep the firm's NDA rules in a shared prompt. For a quarter, log each time a lawyer says the tool missed something. If the log shows repeated clause-level misses on contract types a premium tool is built for, you now have evidence for the quote: how many seats, which document types, which playbooks. Send it in this shape.

Subject: Quote request, [firm name], [number] seats

We are a [number]-lawyer firm reviewing about [number] contracts a month per user.
Please quote, as separate lines:
1. Price per seat per month, and the price if billed annually.
2. Contract length, renewal terms, notice period and price at renewal.
3. Whether Associate, integrations and playbook set-up are included.
4. Support included at our size, and the step-up point.
5. Trial length and conversion terms; can the trial run 14 days?
6. Data terms: zero retention, sub-processors, training exclusion, deletion.
7. The security report available under NDA.
Thank you, [your name]

Whatever you choose, buy with an exit. The per-document sums only work if the volume is real, and volume is easy to overestimate in the excitement of a demo. For the wider context, per-seat against pay-as-you-go pricing for legal AI explains why some tools charge by use and what that does to a small firm's bill.

Spellbook pricing questions

Does Spellbook publish a price?

No. Spellbook's pricing page says pricing is determined by the number of team members on a licence and that personalised pricing needs a demo. It shows no per-user rate, tier names, billing period or minimum seats. Third-party price guides publish estimates without a source, so ignore them and wait for the quote.

How long is the Spellbook free trial?

Seven days. Spellbook's FAQ says lawyers and legal teams can try it free for seven days, and that extended trials may be available for larger organisations. Seven days is short, so prepare the test documents and playbook rules before you start, and ask in writing for a longer trial if you need one.

Is Gavel Exec the same as Gavel's document automation plans?

No. Gavel's published Lite, Standard and Pro plans, from $83 a month, are for document automation. Exec is a separate contract review tool in Word, priced per user at $160 a month or $1,740 billed annually, with 25 free queries per user to start and 1,000 queries a month on paid plans.

Can Copilot in Word review a contract like Spellbook does?

Copilot in Word can draft, rewrite, summarise and answer questions about a document, working within Word and your Microsoft 365 content. The pages I read describe no playbooks or clause benchmarking, so for repeat reviews you would paste your rules into the prompt each time and check every answer yourself.

Does Spellbook train its models on my documents?

Spellbook says it has zero-data-retention agreements so its AI providers never learn from, train on or store your data, and it lists SOC 2 Type II. That is the vendor's statement. Ask for it to be written into the order form together with the list of sub-processors.
