Spellbook legal AI, explained

Spellbook is a legal AI tool for contracts. It installs as an add-in for Microsoft Word and works on the document in front of you: it suggests redlines, flags risky or unusual terms, drafts new clauses and answers questions about the agreement.

It describes itself as built for in-house teams and law firms, from individual lawyers to global legal departments. In practice its centre of gravity is the lawyer in Word. You open the contract, open Spellbook in the side panel, and work through what it suggests.

Around that core it has added more. Playbooks let a lawyer check a contract against preferred positions. Associate runs workflows across several documents. ACM, which Spellbook calls Autonomous Contract Management, adds intake, a contract repository and renewal monitoring.

It is a contracts product. Spellbook doesn't cover litigation or legal research, and it doesn't present itself as a general legal workspace. For a lawyer whose day is spent marking up agreements, that focus is the point. For a legal team whose day is spent answering the business, it is the first sign of the limit.

• Review. Reads the contract open in Word, flags risks and proposes redlines for the lawyer to accept or reject.
• Draft. Writes new clauses and sections to fit the agreement, from a prompt in the side panel.
• Compare. Sets the terms of a contract against market benchmarks, so a lawyer can see where a clause sits.
• Ask. Answers questions about the document: what the termination rights are, who carries the risk, what is missing.
• Playbooks. Checks a contract against a set of preferred positions, so a review follows a standard rather than a hunch.
• Associate. Multi-document workflows, for jobs that span more than one file.
• ACM. Autonomous Contract Management: intake, a repository of signed contracts and renewal monitoring.

The working pattern is simple. A contract arrives. A lawyer opens it in Word, starts Spellbook and asks for a review. Spellbook marks the issues and suggests changes. The lawyer reads each suggestion, accepts what is right, rewrites what isn't, and sends the document on.

That is drafting help, and good for the lawyer who wants it. The judgement, the sequencing and the follow-through stay with the person at the keyboard. If they are in a board meeting, on leave or buried in a dispute, the contract waits.

Spellbook is Word first. A review aggregator reports no Google Docs support, so teams that draft in Google Workspace should check before they buy. Spellbook hosts on AWS in Canada and says it holds zero data retention terms with its model providers, which it doesn't name.

Spellbook doesn't publish prices. Its pricing page prices by the number of people on the licence, offers a seven-day free trial, and adds dedicated support above ten seats.

Estimates put it at about $89 to $200 or more per user per month, and up to about $500 on annual terms.

Price is the wrong place to start, though. The better question is what you are paying for: help for each lawyer while they do the work, or the work itself done for the team. Our legal AI pricing guide sets the numbers side by side.

A Word add-in starts when a lawyer opens a document. In-house legal work starts much earlier, and ends much later. A sales lead pings about a customer's paper. Procurement forwards a supplier MSA. Someone in HR needs a contractor agreement by Thursday. Each request has to be picked up, triaged, done, sent back, filed and remembered at renewal.

Spellbook speeds up the middle of that chain, for the lawyer doing it. Everything either side, and the doing itself, still sits with a person. A team of three with sixty contracts a month still has sixty contracts a month to open, review, accept and send.

Claren is built for the whole chain. Its envoys are AI employees, each with its own computer and its own memory. They take requests from the Claren app or straight from Slack. They read the contract, check it against the team's positions and hand back a tracked-change redline in Word, with a comment on every change, your fallback positions applied and a summary of what is off-playbook. Before anything leaves the team, they ask.

Then they keep going. Envoys file every contract and its key terms in the team's datastore, build the trackers and dashboards the team wants on top, and run routines on a schedule or when a message lands: checking renewals each morning, reviewing every NDA posted in a channel. Your playbook goes in once, and every envoy follows it on every contract.

That is the difference. Spellbook helps a lawyer do the work. Claren's envoys do the work, and hand it to the lawyer to approve.

1. Do you want help with the work, or the work done? If a lawyer wants suggestions while they mark up a contract, Spellbook gives them that. If the team wants contracts reviewed and returned without a lawyer driving each one, that is what Claren's envoys are for.
2. Where do requests come from? In-house requests come from the business, in Slack and email. Claren's envoys pick them up there. A Word add-in starts once a lawyer has the document open.
3. Is it all contracts? Spellbook covers contracts only. If your team also handles diligence, advice notes and the questions that don't fit a template, you need something that takes those too.
4. Who keeps the records? Claren's envoys file every contract and its terms as they go, and build the trackers you want on top: your own CLM views, kept current without anyone updating a spreadsheet.
5. Where does your data need to live? Spellbook hosts in Canada. Claren hosts in the US, UK or EU and holds both SOC 2 Type II and ISO 27001.

If your team has built a playbook for Spellbook, it is the right starting point for Claren. Give it to an envoy once, as a document or in your own words. The envoy keeps it in memory and applies it, with your fallback positions, to every contract that comes in.

Then point the envoy at the work. Link a Slack channel to the team and the envoy picks up what lands there. Drop in your signed contracts and it builds the datastore: parties, dates, renewal terms, liability caps, whatever the team tracks. Set a routine to check renewals each morning. Lawyers keep working in Word for the documents they want to draft themselves, and approve what the envoys send back.

Once envoys are running, the shape of the team's day changes. The routine contracts arrive already reviewed. The lawyers spend their time on the clauses that need a decision, the negotiations that need a person and the advice the business actually asked for.
