Chatbots & AI Assistants
GPT-4o or Claude Sonnet, trained on your data, deployed as REST API or embedded widget. Support, product assistant, intelligent FAQ — we pick the right model based on your token volume, response quality needs, and cost per request.
Autonomous AI Agents
Multi-step task execution: document analysis, API calls, decisions, database writes. LangChain, Anthropic Claude tool-calling, n8n orchestration. Perfect for automating repetitive business processes end-to-end.
RAG & Semantic Search
Give AI precise access to your knowledge base. OpenAI or Mistral embeddings, Supabase pgvector or Pinecone, contextual retrieval pipeline. Document chatbots, smart catalogue search, recommendations.
AI Automation (n8n & Make)
AI-driven workflows: n8n + GPT-4o for extracting data from incoming documents, classifying tickets, writing personalised emails. Make + Claude for CRM enrichment, report generation. Measurable ROI from month one.
Vision & Voice AI
Image analysis with GPT-4o Vision, audio transcription with Whisper, text-to-speech for voice interfaces. Document scanning, accessibility, real-time translation.
Custom AI Applications
Conversational memory, response streaming, multi-agent orchestration, model fine-tuning on your proprietary data. When AI is the core of your product, not an afterthought.

AI in France: a strong foundation
France is home to Mistral AI — born in Paris in 2023, now one of Europe's leading AI model providers. This means French businesses have access to GDPR-compliant, EU-hosted models from day one, without compromising on model quality.
Station F, the world's largest startup campus, has made Paris a global AI hub. BPI France grants and the French Tech network actively fund AI-first startups. Verticals leading adoption include fintech (Qonto, Lydia, Swile), healthtech, and e-commerce — all areas where we have direct project experience.
We build AI solutions adapted to the French regulatory context, including RGPD compliance, data residency options, and integration with French enterprise tooling.
AI development across France
We work remotely with clients across France: Paris, Lyon, Bordeaux, Marseille, Nantes, Toulouse, Strasbourg, Lille. CET timezone, weekly demos, async-first communication.
AI use cases for French companies
AI projects shipped for French clients — with measurable results.
AI assistant for SaaS platform
A French SaaS client wanted to reduce churn by helping users get more value from the platform. We integrated a Claude Sonnet assistant that answers contextual questions, analyses usage patterns, and suggests relevant features. Result: -40% support tickets.
Product chatbot for marketplace
50,000 product listings analysed via OpenAI embeddings + Supabase pgvector. Users ask in natural language, find the exact product in 2 seconds. Delivered in 4 weeks — REST API + dedicated interface.
Document analysis agent
Automatic extraction of key clauses from PDF contracts for a French law firm. Claude Haiku + n8n + Supabase. Processing 200 documents/hour, structured JSON output, automated alerts on sensitive clauses.
AI MVP in 3 weeks
A Paris-based founder wanted to validate an AI-powered user feedback analysis tool. In 3 weeks: scraping, GPT-4o classification, analytics dashboard, Vercel deployment. The tool convinced 10 first paying customers.
Our AI process
From discovery to deployment — a proven methodology for AI projects.
Scoping
We analyse your use case, choose the right AI model (Claude vs GPT-4o vs Mistral), and evaluate cost vs benefit before writing a line of code.
Architecture
We design the stack: AI model, vector store, API backend, user interface. Clear technical decisions made upfront — no surprises mid-project.
Development
API integration, prompt engineering, fine-tuning if required, performance testing and accuracy benchmarks against your data.
Deployment
Production release, AI cost monitoring, iterations based on real usage. We stay available for scaling and model upgrades.
FAQ — AI Agency in France
How much does AI app development cost?
Cost depends on complexity. A simple chatbot integrated into an existing app starts from €3,000–5,000. An autonomous AI agent with RAG and a data pipeline is typically €10,000–25,000. A full SaaS platform with end-to-end AI can reach €50,000+. We always provide a fixed-price quote after a free scoping call.
GPT-4o or Claude — which model should I choose?
Claude Sonnet is generally better for long documents, nuanced tasks, and precise instruction-following — it hallucinates less on structured analysis. GPT-4o excels at multimodal tasks (image analysis), code generation, and general-purpose use cases. In practice, we test both on your specific use case before committing to one.
What's the difference between a chatbot and an AI agent?
A chatbot answers questions in natural language — it searches a knowledge base and formulates a response. An AI agent goes further: it can make decisions, execute actions (send emails, update databases, call third-party APIs), and chain multiple steps to complete a complex task autonomously.
Are our data safe with OpenAI or Claude?
Data sent via the OpenAI and Anthropic APIs is not used to train their models. For strict RGPD requirements, Mistral AI — founded in Paris — offers models that can be self-hosted on European servers or your own infrastructure. We recommend the right approach based on your data sensitivity.
What's the difference between generative AI and predictive AI?
Generative AI (GPT-4o, Claude, Mistral) produces content — text, code, images, natural language answers. It powers chatbots, agents, and content generation. Predictive AI analyses historical data to forecast an outcome: lead scoring, fraud detection, product recommendations. The two approaches are complementary.
