Best AI contract review software: 9 tools ranked on published evidence (September 2026)

AI contract review software in our directory

Contract review is one of five niches in our legal category, next to legal research, eDiscovery, IP and law firm software. Our directory lists 47 legal tools in total; nine of them document an AI function for reviewing contracts and made this list. The rest are research platforms, eDiscovery suites, datasets and benchmarks.

Across the legal software category, 14 tools can keep data in the EU, 9 offer a free trial and 38 are listed with pricing on request. Security reports are common: 28 name SOC 2 and 26 name ISO 27001.

The United States is home to the largest group, 24 legal tools. Europe follows with 5 from the United Kingdom, 3 from Germany and one or more each from Austria, Switzerland and Sweden, which matters for buyers who need contracts to stay under European law.

All nine tools compared: price, free offer and EU data

The table puts the nine tools side by side in ranking order, and the filter below it narrows the list to what your team needs.

Only fynk and BEAMON by BRYTER publish amounts. Juro, Ironclad and Spellbook at least publish what the price depends on, such as contract volume or the number of team members. Legartis, Luminance, Harvey and Legora publish neither a price nor a pricing unit.

How we ranked the contract review tools

Each tool gets 0 to 2 points on four criteria from our own data. Fit: 2 points if contract review is the main niche and an AI review function is generally available, 1 point if review is one module of a broader legal AI platform. Evidence: 2 points if the vendor answers at least 5 of our 6 questions publicly (price, free offer, AI review function, data location, certificate, integration), 1 point for 3 or 4.

Price transparency: 2 points for published amounts, 1 point for a published pricing unit or a free trial without amounts, 0 for pricing on request only. Data residency: 2 points if EU or Swiss storage is the stated default for European customers, 1 point for an EU option for some customers, 0 if no EU location is named.

Ties are broken by fit, then by the number of questions answered, then by the lower published entry price. That rule puts fynk ahead of BRYTER, both at 8 points. No vendor paid for a position, and affiliate links do not change the order. The ranking measures what a buyer can verify before a demo; it does not test how accurately each AI marks up a contract.

1. fynk: the only full price list, with a free plan

fynk is contract management software from Vienna with AI built into every plan. Its AI review lets the AI flag unusual clauses, missing terms and potential risks; AI analysis extracts key data points, and an AI assistant, summaries and AI search sit alongside. Paid plans add an MCP server that connects fynk to assistants such as Claude or ChatGPT.

fynk is the only vendor here with a complete public price list: a free plan for one account with 50 AI credits a month, Essential at 19 euros and Business at 39 euros per user a month on annual billing (29 and 49 euros monthly), and Pro on request. Every paid plan starts with a 14-day trial without a credit card. Data is hosted exclusively in ISO 27001 certified German data centers.

The limits: AI actions consume credits that are shared by the team and reset each month, so heavy review volume means buying top-ups. The pricing page does not mention playbooks, so fynk suits teams that want a quick risk scan more than a check against detailed negotiation positions. It connects to HubSpot through a marketplace app.

2. BEAMON by BRYTER: published per-user prices and Frankfurt servers

BRYTER, based in Frankfurt, sells two products: BRYTER Workflows, a no-code automation platform, and BEAMON AI, an assistant for legal and compliance teams. For contract review, BEAMON analyzes a contract against approved positions and playbook standards and shows non-standard clauses, risk areas and fallback language before the lawyer reads the full text.

BRYTER publishes BEAMON prices per user and month: 99 euros for Single, 149 euros for Team and 199 euros for Pro on annual billing, or 118, 176 and 234 euros monthly. Every license includes unlimited chats, document review with BEAMON Extract and the Word add-in; a free trial is available. EU and EEA customer data stays on servers in Frankfurt, BRYTER is certified to ISO 27001:2022 and SOC 2 Type II and states that customer data is never used to train AI models.

The limits: Single is only for solo practitioners and has no team features. Workflows, single sign-on and the SharePoint integration are reserved for Pro, and BRYTER Workflows itself is priced on request.

3. Juro: playbook redlines in Word, data in the EEA

Juro is a UK contract platform with a browser editor and eSignature. Its AI contract review lets agents review third-party contracts against your playbooks and redline them, started from Microsoft Word; every AI response comes with the reasoning and the playbook rule behind a redline.

Juro does not publish amounts. All plans include unlimited users, workflows and templates, and the price depends on contract volume and the integrations you need; quotes come in US dollars, pounds or euros. Slack, Google Drive and Companies House are included, while Salesforce, HubSpot and Workday cost extra. Contracts are stored with Amazon Web Services and MongoDB in the EEA, and Juro holds a SOC 2 Type II attestation.

The main limit is language: AI contract review is currently only available in English, while the AI Assistant and AI Extract support several languages. No free trial is published.

4. Ironclad: the Jurist agent inside an enterprise CLM

Ironclad is a contract lifecycle management platform from San Francisco. Its AI contract partner Jurist redlines entire contracts against an uploaded playbook, extracts legal, financial and operational risks and drafts memos and letters. Jurist for Microsoft Word, marked as new on the product page, surfaces risks and applies positions inside the document.

Ironclad quotes individually; the pricing page names products, users, workflows and add-ons such as API access, integrations or extra instances as price drivers. Its Salesforce integration is approved on AppExchange. Data is stored in the United States or, for certain customers, in the European Union. The security page lists SOC 1 and SOC 2 Type II reports and a section on ISO 27001, 27017 and 27018.

The limits: Jurist is built on Ironclad CLM, so it is a choice for teams that want the whole platform, not a stand-alone reviewer. EU storage is not the default, and no trial is published.

5. Spellbook: a Word add-in with a 7-day trial

Spellbook runs as a Microsoft Word add-in for law firms and in-house teams. The Spellbook Suite includes Review, Draft, Ask, Benchmarks and Playbooks in Word, plus Associate, an agent for matters that span several documents. Playbooks save your instructions for how Spellbook should review a document.

Spellbook prices by the number of team members on the license and quotes after a demo; lawyers and legal teams can start a 7-day free trial, and larger organizations may get longer trials. The vendor is headquartered in Canada, holds SOC 2 Type II and has zero data retention agreements with OpenAI and Anthropic. Sign-in runs through Microsoft accounts.

The limit for European buyers is storage: customer data is stored and processed in data centers in Canada and the US. Spellbook's newer contract management system, ACM, is offered as early access and is not part of this ranking.

6. Legartis: review in every European language, servers in Switzerland

Legartis is a Zurich company that calls its product a Legal AI Workspace. AI Contract Review checks each incoming contract against your Contract Playbook, links every deviation to the rule it breaks and proposes wording; the Contract Playbook Creator builds playbooks per contract type, and a Legal Agent handles drafting and custom workflows.

Legartis reviews common contract types in every European language and was trained on German-language contracts from Germany, Austria and Switzerland as well as common law contracts. Servers are in Switzerland and Europe, the company is ISO 27001 certified and uses locally stored language models; on-premise deployment is available on request.

The limit: no price, no trial and no list of integrations on the pages we checked, which leaves Legartis at 5 points despite a strong fit.

7. Luminance: playbooks plus your own precedent

Luminance, founded by researchers from the University of Cambridge, splits its platform into negotiation, repository and workflows. In negotiation, it applies your playbooks, preferred positions and precedent to every contract, marks up deviations and generates context-aware markups in Microsoft Word, even where a formal playbook position does not exist yet.

Luminance holds ISO 27001 and undergoes SOC 2 Type II examinations; data is encrypted with AES-256 and hosted in AWS. The security page does not say in which region customer data is stored, and there is no public price or trial.

Its strength is precedent: Luminance compares a new draft with what you accepted before from the same counterparty.

8. Harvey: review agents on a broad legal AI platform

Harvey is a legal AI platform from San Francisco for law firms and legal departments. Its Contract Intelligence module detects the contract type, runs a review against your playbook, benchmarks terms against executed deals and tracks obligations; contracts arrive from Outlook, Jira, SharePoint, iManage, Box or Google Drive.

Harvey hosts on Microsoft Azure and offers processing in the EU and Switzerland or in Australia for customers with localization needs. It names SOC 2 Type II, ISO 27001, ISO 27701 and ISO 42001 and does not train models on customer data. No price is published.

The limit is timing: Harvey announced Contract Intelligence on May 21, 2026 with a waitlist for early access and general availability planned for the third quarter. Ask in the demo whether it is included in your contract.

9. Legora: Automated Playbooks in Word

Legora is a collaborative legal AI platform with a technical team in Sweden. Its Word add-in brings the Legora Agent into Microsoft Word to draft, redline and review, and Automated Playbooks apply customizable rule sets to documents such as NDAs and service agreements. Tabular Review analyzes many documents at once.

Legora names ISO 27001, ISO 42001 and SOC 2 Type 2, operates under the GDPR and does not use customer data to train or fine-tune models. When a customer contract ends, all data is permanently deleted, with the option to request a full export first.

The limits: no price, no trial and no storage region on the public pages. Like Harvey, Legora is built for broad legal work, so contract review is one part of a larger subscription.

Rules to check before contracts go into an AI tool

Contract review by a company's legal team is not on the EU AI Act's high-risk list. Annex III covers the administration of justice only for AI used by or on behalf of a judicial authority, or in a similar way in alternative dispute resolution. The AI literacy duty has applied since February 2, 2025, and the Annex III obligations apply from December 2, 2027 after the AI Omnibus.

Data protection matters more in daily use. A vendor that processes personal data in your contracts on your behalf is a processor under Article 28 GDPR and needs a written contract that covers subprocessors and deletion. Ask where the language model runs as well, because several vendors here route requests to model providers.

Law firms face professional secrecy rules on top. In Germany, section 43e of the Federal Lawyers' Act requires lawyers to choose service providers carefully, bind them to confidentiality in text form and, for services abroad, check that secrets are protected comparably. BRYTER states that BEAMON complies with these rules.

Which type of contract review tool fits your team

Start with where your lawyers work. If most contracts arrive as Word files from the other side, a Word add-in such as Spellbook, BEAMON, Juro, Luminance or Legora fits the daily routine. If contracts also need a repository, approvals and signatures, a platform like fynk, Juro or Ironclad covers the whole lifecycle.

Then test with your own material. Load one of your playbooks, review a real third-party contract that your team already negotiated and compare the AI markup with the final version. Ask for the price for your exact number of users or contracts, including AI credits or add-ons, and get the data location in writing.

Tools we checked and left out

Three legal platforms with full profiles in our directory did not make the list. Lexis+ with Protégé describes drafting of agreements and contracts, and CoCounsel Legal accepts a contract review as one of many tasks you can describe in plain language; both are built around legal research, and neither page describes a review against your own playbook.

Noxtua, a Berlin legal AI with European hosting, offers a Word add-in that refines documents with AI, but its pages do not describe contract review as a function of its own. We will add any of the three if the vendor documents a dedicated review function.
