How it works

Simple to install,
powerful to use

No technical skills required. Our team handles everything — you start working from day one.

01
On-site installation

We deliver and configure the hardware directly at your firm. Connected to your network, secured, your solicitors trained. Less than one working day.

02
Load your case files

Upload contracts, pleadings, bundles, scanned documents. LegisBox indexes everything, converts scans to searchable text, and organises your archive automatically.

03
Ask in plain English

Ask questions as you would to a colleague: "What are the termination clauses in this lease?" or "Find all adverse authorities on this point of law." Lex answers with source citations.

FAQ

Frequently asked questions

Confidentiality & compliance
Never. LegisBox is installed physically in your firm. Your clients' documents never leave your local network. An internet connection is only used to download updates to public law (BAILII, legislation.gov.uk, Find Case Law, ICO decisions) — never to transmit private client data.
No. Uploading confidential client files to ChatGPT, Claude, Gemini or any cloud service risks breaching Legal Professional Privilege, UK GDPR, and the SRA Code of Conduct. The SRA has issued formal Warning Notices about "Shadow AI". Your data reaches servers outside your control, often outside the UK. LegisBox eliminates this risk: the AI is in your firm.
Absolutely. LPP requires that privileged communications remain confidential. Uploading client files to any cloud AI — even one claiming UK compliance — risks waiving privilege permanently and irreversibly. LegisBox processes everything on-premises: no third party ever sees or handles your files. This is the only way to guarantee absolute protection.
Cloud providers claiming UK hosting can still sub-process data through entities subject to US Cloud Act requests or other extraterritorial legislation. A data centre in London does not guarantee your data cannot be accessed by a foreign government or parent company. With LegisBox, the hardware is physically in your firm — you can see it, touch it, disconnect it. That is the only absolute guarantee.
How it works
Less than one working day. Our team handles everything: hardware delivery, network installation, secure configuration, and training for your solicitors. No technical skills required from your side. You can begin using it the same day it arrives.
Yes. LegisBox is installed in your firm and works completely offline. An internet connection is only used for automatic nightly updates to public law (BAILII, legislation.gov.uk, Find Case Law, ICO decisions). Your case files and AI remain available even during a network outage.
The fundamental difference is where your data is processed. ChatGPT, Claude, Gemini and Copilot send your clients' documents to foreign servers outside your control, risking LPP waiver and UK GDPR breaches. LegisBox processes everything locally — zero data leaves your network. LegisBox is also specialised in English and Welsh law: it knows BAILII, legislation.gov.uk, the SRA Code of Conduct, and CPR deadlines.
Pricing & value
Yes, everything is included in the monthly fee: automatic nightly updates to legislation and case law (BAILII, legislation.gov.uk, Find Case Law, ICO, SRA guidance), technical support, hardware and software maintenance, and AI updates. No hidden costs.
Yes. The LegisBox subscription is an allowable business expense for solicitors and barristers. For a 45% higher-rate taxpayer, the effective monthly cost of the Solo plan (£499/month) is approximately £274/month — automatically, without any special application. The hardware lease is also eligible for capital allowances under HMRC rules.
Westlaw Edge and Lexis+ AI typically cost £200–600 per user per month — and they are cloud-based, raising LPP and UK GDPR concerns. LegisBox at £499/month covers your entire firm, includes full case analysis and drafting capabilities, and keeps all data on-premises. The economic argument is straightforward: LegisBox replaces approximately 40 hours of a junior fee-earner's research time per month at National Living Wage. See the full cost comparison →
