    Training overview

    In 2026, legal professionals no longer just use generative AI — they build their own tools. Custom GPTs specialized in contract law, Claude agents for due diligence, no-code applications for letter generation: building tailor-made legal AI tools has become a major competitive advantage for firms and legal departments.

    This training offers a complete path, from the most accessible to the most advanced. You will learn to design a Custom GPT or Claude Project perfectly calibrated for your practice, then to take the next step by building a real no-code application (Lovable, Bubble, n8n) deployable to your colleagues or clients.

    The approach is resolutely practical. Not a single line of code will be written. After 7 hours, you leave with two functional deliverables: an AI assistant specialized for your daily work, and the prototype of an operational legal application adapted to a use case from your firm.

    Learning objectives

    Identify relevant legal use cases for building tailor-made AI tools
    Design and deploy a specialized Custom GPT or Claude Project
    Write robust and ethically safe instruction files (system prompts)
    Build a functional no-code legal application prototype
    Connect an AI assistant to internal documentary sources (simplified RAG)
    Secure deployment with respect to professional secrecy and GDPR
    Evaluate the technical and economic viability of a legal AI tool project
