Private AI for law firms and advisory firms in Barcelona

An assistant that knows your case files and templates, runs inside the firm and never exposes a single piece of client data.

We install a private AI in your firm that drafts documents, summarises case files, searches your records and transcribes meetings without sending anything to the cloud. It protects professional secrecy and makes GDPR compliance easier. We start with a free assessment at your Barcelona office or by video call.

The problem

  • The team already pastes client data into ChatGPT: 27.4% of legal professionals admit it (Barómetro Sector Legal Digital 2026).
  • We use AI, but with no rules: half of organisations have given no instructions at all and only 12.7% have a written policy.
  • The CGAE (Spain's General Council of Lawyers) has already issued an ethics circular on documents drafted with AI and has announced another on confidentiality. We don't know whether we comply.
  • Per-user licences for AI legal tools keep going up and we have no control over where the documents end up.
  • We lose hours searching old case files, template documents and emails for something we already solved once.

Use cases

  1. 01

    Drafts based on your templates

    Claims, defences, appeals or contracts drafted from your own templates and the case file itself, in the firm's house style. The lawyer reviews and signs.

  2. 02

    Firm-wide search with citations

    Natural-language questions about case files, legal opinions, saved case law or internal notes, with each answer linked to the source document and page.

  3. 03

    Case file summaries and due diligence

    Reading hundreds of pages (PDFs, scans, emails) to produce a timeline, the parties, the deadlines and the critical points in minutes.

  4. 04

    Minutes of meetings and calls

    Transcription on your own server, with who said what, a summary and action points. The recording never leaves the office.

  5. 05

    Tax and employment advisory queries

    Answers on collective agreements, tax forms and internal circulars, plus draft replies to clients or to formal requests from the authorities.

  6. 06

    Contract review

    Comparison against your standard clauses, alerts for clauses that are missing or deviate, and suggested alternative wording.

  7. 07

    AI use policy and team training

    We draft your internal AI use policy with you and train the team, as required by Article 4 of the EU AI Act.

The situation in Barcelona’s law firms

AI has already made its way into law firms, but through the back door. According to the Barómetro Sector Legal Digital 2026, which surveyed 6,512 professionals, 69% already use it, yet half of organisations have given no instructions at all and 27.4% admit to having entered real client data into ChatGPT. In a Barcelona law firm or advisory firm, that means claims, payslips, deeds and income tax returns passing through third-party servers with no contract and no record.

The profession is moving. The Consejo General de la Abogacía Española (Spain’s General Council of Lawyers) has already published a circular on documents drafted with AI and has announced another on confidentiality. And outside Spain, a US federal judge has already ruled that conversations with an AI are not covered by attorney-client privilege. The answer is not to ban AI, but to keep it in-house.

What private AI looks like day to day

At nine o’clock, a lawyer asks for a summary of the 400-page case file going to trial this week: timeline, parties, deadlines and key documents, each point with its citation. An adviser at the firm asks which internal circular explained how to handle expense allowances and gets the exact document. In the afternoon, a client meeting is transcribed on your own server, identifying who is speaking, and produces minutes with the outstanding tasks.

Everything runs on a machine inside your office, with individual accounts, usage logs and no per-token fees. We work this way every day: in our lab we transcribe meetings with speaker identification locally, and our private gateway has served around 11.15 billion tokens without paying for each one.

How we deploy it

  1. Assessment. We look at the documents you handle, which tasks take up the most hours and which data is sensitive. You come away with prioritised use cases, an architecture and a fixed proposal.
  2. Pilot of 2 to 4 weeks. One specific case (for example, case file search) with a small group and your real documents. We measure time saved and quality.
  3. Production. Final installation, accounts for the whole team, an AI use policy, training and maintenance so the models are updated without interruptions.

Catalan and Catalan law

A large share of case files in Catalonia are in Catalan, and the Codi civil de Catalunya has its own terminology. Today’s open models, together with resources from the AINA project and Softcatalà, make it possible to work in Catalan to a high standard. We have gone a step further: we built a Catalan vocabulary pipeline that raised the coverage of the ‘draft’ model that speeds up responses (a technique known as speculative decoding) from 75.2% to 99.6%. Catalan is not a second-class language for us.

When you don’t need it

If your use is limited to drafting generic texts or searching public information, with no client data, a cloud business subscription with a data processing agreement may be enough. We will tell you so in the assessment, even if it means not selling you a server.

AI and GDPR assessment

AI and GDPR assessment for your business in Barcelona

We review how you use AI today, what data it touches and what obligations you have. You leave with a clear plan: what to run locally, what can go to the cloud and in what order.

Timeline: 1 to 2 weeks

Frequently asked questions

Can I use ChatGPT with my clients' data without breaching the GDPR?

Not with a personal account: there is no data processing agreement and you have no control over where the data is stored. Business plans solve part of the problem, but the documents still leave the firm. With local AI, processing happens on your own hardware, with no third parties and no international transfers.

What hardware does a law firm or advisory firm need?

For a firm of 5 to 20 people, a compact server such as the NVIDIA DGX Spark, installed in your office, is usually enough. We size it according to the number of people and the modules you switch on, such as document search or transcription. The first assessment is free, at your Barcelona office or by video call.

Does the AI replace the lawyer's review?

No. It proposes drafts and summaries with citations to the original document so they can be checked in seconds. Review and signature always remain with the professional, as the CGAE circular on AI-drafted documents points out.

Does it work with documents in Catalan?

Yes. The models we install read and write in Catalan and Spanish, including the terminology of the Codi civil de Catalunya (the Catalan Civil Code). We have also worked on our models' Catalan vocabulary so that drafting in Catalan is no slower.
