Legal AI pricing, and Harvey's cost

Ask Harvey, Legora or Spellbook what they cost and the answer is a sales call. None publishes a price list; each prices by quote.

What fills the gap is estimates: review sites, pricing indexes and guides written by other legal AI companies. Several of the guides that rank for these searches come from the vendors' own competitors, and many repeat each other. They are a starting point, not a quote.

Below, every figure for a named vendor is labelled as an estimate and linked to where it comes from. Claren's figures are its published plans.

1. The price per seat. Most legal AI is sold per person, per month or per year. It is the figure articles quote, and the least useful on its own.
2. The minimum number of seats. Enterprise vendors are reported to set a floor on licence counts. A team of five that must buy twenty seats pays for fifteen people who don't exist.
3. The contract term. Twelve-month contracts are reported for Harvey and annual terms for Spellbook. An annual commitment makes a trial a year's budget line.
4. Usage. AI runs on models, and models cost money per use. Ask whether it is in the seat price, and what happens in a heavy month.
5. The hours your lawyers spend running it. A tool that drafts for a lawyer to finish still needs the lawyer. The real cost of legal AI is the price plus the time your team spends driving it. Most comparisons leave it out.

Harvey doesn't publish prices. It sells by custom quote, and minimum licence counts and 12-month contracts are reported.

LawXYAI's review puts Harvey at about $1,200 per seat per month with a 20-seat minimum: about $288,000 a year before the first matter. Vaquill, itself a legal AI vendor, estimates $1,200 to $2,000 or more per seat. Both are estimates.

For that, a firm gets Harvey's platform: Agents, Vault for bulk document analysis, Knowledge for research, Spaces, Contract Intelligence, Horizon Scanning, and Word and Outlook add-ins. Intake and Legal Work Orchestration, aimed at in-house teams, are marked new.

It is a toolkit priced for a large firm with many lawyers to put in front of it. For an in-house team of five, the seat minimum alone sets the bill.

Legora doesn't publish prices either. Estimates from Layer3Labs, Spellbook and Vaquill put it at about $3,000 per user per year with a 10-seat minimum, which is about $30,000 a year at the floor. Larger enterprise deals are reported at $5,000 to $8,000 per user per year.

The money buys Legora's Agent, Tabular Review (one grid that pulls the same answers from many documents), Workflows, Legal Research, Word and Outlook add-ins, a client Portal and newer modules including Intake.

Tabular Review is suited to bulk review on a deal. In-house work mostly arrives one request at a time, and a ten-seat floor is a lot of seats for a team that size.

Spellbook prices by the number of people on the licence and doesn't list a figure. It offers a 7-day free trial and dedicated support above ten seats. Estimates run from about $89 to $200 or more per user per month, with figures up to about $500 reported on annual terms.

It works mainly inside Microsoft Word: review with redlines, drafting, market comparison, playbooks, multi-document workflows, and ACM for intake, a repository and renewals. It covers contracts only.

On the estimates, it is the cheapest seat of the three. It is also the narrowest: drafting help for one lawyer at a time, in Word.

A five-person team pays for five seats on Claren and Spellbook. On Legora's reported floor it pays for ten, and on Harvey's for twenty. Half of the Legora licence, and three quarters of the Harvey one, would sit unused.

Claren's $15,000 also carries $12,000 of usage: $200 per seat per month, pooled across the team, covering models, computer time and storage. Beyond the pool, usage is pay-as-you-go at the plan's rate.

Spellbook comes out cheapest on paper. It buys a drafting assistant in Word for each of the five, and the work still waits for one of them to finish it.

Every other product on this page sells seats of a tool. A seat gives one lawyer a better way to research, draft or review. The lawyer still picks up the request, runs the tool, checks the output and files the result. The price buys speed for the person at the keyboard.

Claren is priced per seat too, but a seat buys something different. It gives the team envoys: AI employees, each with its own computer and its own memory. They take requests from the Claren app or straight from Slack, review every contract against the team's playbook, hand back tracked-change redlines in Word with a comment on every change, and file each contract and its terms in the team's datastore. Routines run on a schedule or when a Slack message lands, without anyone asking.

That changes the sum. The cost of a tool is its price plus the hours your lawyers spend driving it. The cost of an AI employee is its price, and the hours come back. Every contract redlined, every renewal flagged and every request picked up is time the team gets back, every week.

For a team with more requests than lawyers, the useful comparison isn't Claren against another tool's seat. It is Claren against outside counsel and the next hire.

The general AI assistants publish their prices, and they are low. Claude Pro is $20 a month ($17 on annual billing); Claude Team Standard is $25 per seat monthly ($20 annual) for 2 to 150 seats, and Team Premium $125 ($100 annual). Claude Enterprise is $20 per seat on an annual plan plus usage at API rates, with a 20-seat minimum. Anthropic's legal plugins run on these plans.

ChatGPT Business is reported at about $20 per user per month on annual billing and $25 monthly, with a two-seat minimum. OpenAI has no legal-specific product. Microsoft 365 Copilot Business is $21 per user per month for up to 300 users, and Microsoft's Legal Agent in Word needs a Copilot licence. Google Workspace includes Gemini from $14 per user per month on Business Standard.

The per-seat price is the smallest part of the cost. Each lawyer sets the assistant up, writes the prompts, keeps their own playbook in step and checks every answer. Many of Claude's legal connectors need your own subscription to the product behind them. None of them picks up a request from the business, keeps your contract records or runs a routine for the team. Those hours are the bill.

Claren's envoys run on models from OpenAI, Anthropic and Google, so a team keeps its preferred model and stops paying its lawyers to operate it.

1. How many seats will you actually use? Price the team you have, not the minimum on the contract. For a team of five, a 20-seat floor costs four times what it should.
2. What happens in a heavy month? Ask whether usage is included, pooled or billed on top. Claren includes it per seat, pools it across the team and charges pay-as-you-go at the plan rate beyond that.
3. Who does the work once it's bought? If the answer is still your lawyers, add their hours to the price. If it is an envoy that picks up the request and hands it back finished, the hours come back to you.
4. Can you start before you sign for a year? Claren has a free plan and published monthly prices per seat. Spellbook offers a 7-day trial. Harvey and Legora are sold by quote.

Start with the work that repeats: NDAs from sales, supplier contracts, the DPA a customer wants back by Friday. Put the playbook in once, point an envoy at the Slack channel where those requests land, and count the hours.

Claren's Free plan covers one member, with $5 of usage to start and $1 a day after that. Pro covers one to three members at $70 per seat per month. Team, for three or more, is $250 per seat per month with shared team envoys and $200 of usage per seat, pooled. Enterprise adds zero data retention and SSO, priced with your team.
