AI legal software costs $99 a month here for 100 document reviews, $299 for 500, and $1,749 for unmetered use. Annual billing halves every one of those rates. There is no seat minimum, no quote process and no sales call, which is unusual in this category: Harvey, CoCounsel, Lexis+ AI, Legora and Spellbook all publish no price at all.
Prices below are the ones you are charged, not a starting point for a negotiation.
Perfect for individual attorneys starting with AI for lawyers
Ideal for small to medium law firms using AI tools for lawyers
For established firms needing unlimited AI for lawyers
Elite covers firms of up to 50 colleagues with unmetered reviews, a named support contact and a custom confidentiality agreement
Compare plansThe reason "how much does legal AI cost" is hard to answer is that almost nobody in the category answers it. Here is the state of published pricing among the tools US firms shortlist most often, checked in October 2026. Figures that are not published by the vendor are labeled as third-party estimates, because that is exactly what they are.
| Tool | Price published by the vendor? | Cost | How you buy |
|---|---|---|---|
| LegalSoul | Yes | $99, $299 or $1,749 per month, half that on annual billing | Self-serve, no seat minimum |
| Harvey | No | Reported from about $333 per user per month (an indicative $40,000 a year for 10 users) to $1,000 to $2,000 or more, third-party estimates | Sales call, seat minimum reported |
| CoCounsel (Thomson Reuters) | Partly | Westlaw Advantage with CoCounsel Essentials listed from $256.75 a month. CoCounsel Legal reported at $637 to $784 per attorney per month, third-party estimate | Configurator under 10 attorneys, sales rep above |
| Lexis+ AI | No | Reported roughly $250 to $500 per seat per month all in, third-party estimate. Per-use AI charges are published: $99 per Generative AI Ask | Quote, usually on top of a research seat |
| Legora | No | Reported around $300 to $800 per seat per month, or about $3,000 per seat per year at list, third-party estimate | Demo, then a pilot. Reported 10 seat minimum |
| Luminance | No | No reported seat price at all. An implied average of about $43,000 to $60,000 per customer per year, derived from reported ARR and customer count | Demo, then a pilot. Metered on document volume, contracts reported at 36 months |
| Spellbook | No | No dollar figure on its own pricing page, priced by number of team members on the license | Demo, then quote. A 7 day trial is offered |
| Kira (Litera) | No | Reported from about $5,000 a year for a small team to $50,000 to $150,000 or more, third-party estimates | Demo, then quote |
| Ironclad | No | Median signed contract $40,110 a year across 371 purchases (Vendr) | Demo, then quote, annual contract |
| LinkSquares | No | Median signed contract $31,000 a year across 152 purchases, range $5,999 to $79,200 (Vendr) | Demo, then quote, annual contract |
Two honest caveats. First, those tools are not all doing the same job: CoCounsel and Lexis+ AI carry legal research libraries, Spellbook drafts inside Word, Luminance is priced for a whole contract repository rather than a seat, and the price reflects that. Second, a quote is not automatically a bad deal, and a large firm with procurement staff often negotiates down. But if you are a solo practitioner (our guide to AI for solo practitioners compares fourteen tools with prices) or a firm of two to fifty attorneys, the sales cycle itself is a cost, and a published number you can approve today is worth something the discount never gives back.
Full breakdowns for the tools US firms ask about most: CoCounsel pricing per user per month, Spellbook pricing and cost, Lexis AI pricing per user, Legora pricing per seat, Luminance legal AI pricing, Kira pricing for contract review, Ironclad pricing and CLM cost, LinkSquares pricing per year and Harvey AI pricing for small law firms. If you are actively replacing a quoted platform, the Harvey alternative comparison lays out where each tool genuinely wins.

Published AI legal software for document review runs roughly $99 to $300 a month for a small firm, and the enterprise research platforms are reported between $250 and $1,500 per user per month on a quote. Here the numbers are fixed: $99 for 100 reviews a month, $299 for 500, $1,749 unmetered, halved on annual billing.
Most of the category charges per seat, which is why a five-attorney firm often sees a five-figure annual number. These plans are priced per account on a review allowance instead, so the cost tracks how many documents the firm actually puts through rather than how many people have a login.
No to both. There is no minimum number of seats and no annual commitment required to start, so a solo practitioner pays the same listed rate a larger firm does. Annual billing exists because it is cheaper, not because it is required, and monthly plans can be cancelled at any time.
Yes, and there is no contract to break. Open Billing in the app, choose Update subscription and pick the plan you want: the change applies straight away and only the difference for the rest of the period is charged, so nobody ends up paying for two plans at once. If you would rather we moved you across by hand, write to [email protected].
Your screen shows how many reviews are left before every run. When the last one is used, the review button stops and offers you a bigger plan; the reviews you have already run stay on your account and stay downloadable. A paid allowance refills on the first day of each month. Elite is unmetered.
Yes. You can review a document on the home page without an account, and a free account gives you 3 reviews once, not every month: there is no free plan. Free reviews are shortened and downloads carry a watermark; a paid plan removes both. No card needed to start.
Yes. Annual billing is half the monthly price on every plan: $49 instead of $99, $149 instead of $299, $874 instead of $1,749 per month. The saving is shown on the plan cards above.
Card payments through our secure payment processor: Visa, Mastercard, American Express, Discover, JCB, UnionPay and Diners Club. If your firm needs a bank transfer or an invoice instead, write to [email protected] and we will arrange it by hand.
