Contracts are the lifeblood of business, but getting them reviewed by a solicitor in England and Wales often costs £300+ per hour. For small businesses, freelancers, and consumers, this creates a dangerous choice: pay expensive fees or sign risky documents without understanding them.

Fortunately, a new wave of UK-specific AI Legal Tools has emerged to bridge this gap. But with so many options—some focused on corporate teams, others on drafting—it’s hard to know which is right for you.

We’ve tested and compared 4 of the leading British AI contract review platforms: Caira (Unwildered), Genie AI, Robin AI, and Juro.

At a Glance: Feature & Pricing Comparison

1. Unwildered

Best For: Freelancers, Consultants, and SMEs needing fast, private reviews.

Unwildered is designed for the 99% of businesses that don't need a complex legal department—they just need to know if a contract is safe to sign. It focuses purely on Reviewing and Redlining existing documents (Word or PDF).

Why it stands out:

• Zero-Trust Privacy: Unlike most tools that process your data on their servers, Caira uses "Local-First" technology. Most of the analysis happens directly in your browser, and your documents aren't used to train public AI models.

• Incredible Value: With a free tier for occasional users and a "Starter" plan at £15/month, it is significantly more affordable than enterprise-focused rivals.

• Instant Access: There are no sales calls or "Book a Demo" buttons. You can sign up and get your first review in under 30 seconds.

• Track Changes: It exports a Word document with "Track Changes" ready to send back to your counterparty, along with a drafted negotiation email.

Verdict: If you already have a contract and just need to check it for risks (e.g., liability caps, termination clauses), Caira is the fastest and most affordable option.

2. Genie AI

Best For: Drafting contracts from scratch using templates.

Genie AI is a well-established player in the UK market, famous for its "Open Source" library of legal templates. If you don't have a contract yet and need to create an Employment Agreement or NDA from scratch, Genie is a powerhouse.

Why it stands out:

• Template Library: Thousands of free templates are available, which you can customise using their AI editor.

• "Ask Genie": A helpful chatbot feature that drafts clauses for you based on simple prompts.

• Community: A strong community of solicitors and users constantly improving the template base.

Trade-off: While excellent for drafting, the reviewing capabilities are part of a more expensive ecosystem. The "Pro" plan starts at £30/month for just 10 documents, making it pricier than Caira for high-volume review needs.

3. Robin AI

Best For: Corporate Legal Teams and Private Equity.

Robin AI is a heavy hitter in the legal tech space, often used by large in-house teams. They combine AI with a "human-in-the-loop" service (actual paralegals/solicitors checking work), ensuring high accuracy for complex deals.

Why it stands out:

• Microsoft Word Add-in: Their tool lives directly inside Word, which solicitors love.

• Human Hybrid: The option to have a human verify the AI's work offers peace of mind for high-stakes M&A deals.

• Speed for Volume: Designed to process hundreds of pages for due diligence quickly.

Trade-off: The pricing is geared towards enterprise. You generally need to speak to a sales team to get started, and the costs are significantly higher than self-serve tools.

4. Juro

Best For: Sales teams needing signatures and storage.

Juro is an "All-in-One" contract automation platform. It’s less of a standalone "review tool" and more of a workspace where contracts are created, negotiated, signed, and stored.

Why it stands out:

• End-to-End Workflow: You can build the contract, send it for e-signature, and store it in a searchable database all in one place.

• Integrations: Connects seamlessly with Salesforce, HubSpot, and Slack, making it perfect for aggressive sales teams closing deals.

• Data-Rich: Treats contracts as data (not just files), allowing you to query things like "renewals in Q3".

Trade-off: It is a complex platform (CRM for contracts). If you just want to check a PDF a client sent you, Juro is probably overkill and starts at a higher price point (~$59+).

The "Privacy" Differentiator

One critical factor often overlooked is Data Privacy. When you upload a sensitive client contract to a cloud-based AI, where does it go?

• Cloud-Based (Genie, Robin, Juro): Your data is uploaded to their central servers/databases to be processed. While they have strict security, your data leaves your possession.

• Zero-Trust (Caira): Caira processes files primarily on your device using sandboxed environments. This "Zero-Trust" approach means your sensitive commercial data isn't sitting in a centralized database waiting to be breached.

Summary Recommendation

• Choose Unwildered's free ai contract review tool if you are a freelancer, SMB, or consumer who needs to review contracts quickly, cheaply (£15/mo), and privately.

• Choose Genie AI if you need to create contracts from scratch using templates.

• Choose Robin AI if you are a large corporate legal team needing human verification.

• Choose Juro if you are a sales team needing integrated e-signatures and CRMs.
