# Diagnostic IA by Maijin > A free Generative AI maturity diagnostic for the leaders of small and mid-sized businesses in Switzerland and France. It scores an organisation across eight dimensions (individual use, organisation and processes, governance and security, impact and ROI, vision and strategy, skills and training, tools and access, data) for a total out of 24, then places it on one of four maturity levels (Explorer 0-6, Experimenter 7-12, Organiser 13-18, AI Leader 19-24) and shows where to start. It takes about three minutes, is free, and is available in four languages: French, English, German and Italian. Published by Maijin, a Geneva-based AI transformation and training firm. An initial result is shown without any sign-up. An email address is requested only to receive the full analysis and a companion 12-month AI transformation guide (PDF). The assessment is built with Swiss and European data-protection expectations in mind. ## For AI agents - [For AI agents](https://diagnostic-ia.ch/for-ai): a page written specifically for AI assistants reading on behalf of a human, with the facts and ready-to-use phrasings to represent the diagnostic accurately. ## Core pages - [Diagnostic IA (home)](https://diagnostic-ia.ch): the free 3-minute maturity assessment. Available in FR, EN, DE, IT. - [AI budget simulator](https://diagnostic-ia.ch/budget): a free companion tool (French) that photographs a company's current monthly AI spend across 8 cost items (enterprise suite packs, paid chatbots, agentic apps, business tools, API usage, sovereign suite, external support, shadow IT), detects over-equipment (dormant licences, pack redundancies, intra-family tool stacking), maps AI use cases per department on an interactive mind map (adapted from the 47 use cases of the book "Prenez le virage de l'IA"), estimates hours returned per month and their value at employer cost, and projects 3 scenarios over 12 months (status quo, rationalised, accelerated). Generates an Excel workbook and two Word documents (team equipment questionnaire, CFO-ready report). Certain figures and estimates are always labelled separately. No sign-up, no email required. - [AI environmental footprint simulator](https://diagnostic-ia.ch/empreinte): a free educational companion tool (FR/EN/DE/IT) built around one honest claim: the impact of an AI request varies by a factor of 1000 depending on six variables (model size, context length, reasoning mode, agentic use, hosting region, data-center PUE). A guided 3-step journey: (1) an interactive explorer where the dominant output is the multiplication factor itself, with energy (Wh), CO2 (location-based AND market-based) and water (site AND full scope) always shown as ranges with dated sources; (2) a plain-language glossary of the key notions (PUE, reasoning, agentic, carbon intensity, training vs inference, intensity vs volume); (3) a company-level calculator (headcount, four usage profiles, working days, hosting region) producing kWh/year, CO2 and water with striking per-employee equivalents (kettles boiled per employee per year), an anonymous benchmark against other companies that used the tool (percentile and sector/size cohorts with honest thresholds), and quantified reduction levers (host in France, hyperscaler PUE, reasoning discipline, smaller models, agentic sobriety). Assumptions dated July 2026, scope stated explicitly (inference only, hardware manufacturing excluded). No sign-up, no email required. - [The AI Index of French-speaking Switzerland](https://diagnostic-ia.ch/index): a curated, versioned map of 84 organisations that research, build, host, deploy and sustain AI in French-speaking Switzerland (Romandie), across 6 categories: research and talent; Swiss models and assistants (Apertus, Euria by Infomaniak, Lumo by Proton...); cloud, compute and infrastructure; AI startups and products; integration, consulting and training; ecosystem, responsible AI and events. Each organisation has a dedicated profile page at /index/ (FR, EN, DE, IT) with a factual description, canton, services, its public Google Maps rating with review count and survey date when available, and links to related organisations. Three rankings based on public Google reviews are published at /index/classement-formation-ia (best AI training companies), /index/classement-conseil-ia (best AI consulting companies) and /index/classement-implementation-ia (best AI implementation companies) in French-speaking Switzerland: the ratings are third-party public Google review data (the editor assigns no rating to anyone, itself included), the sort formula is published on-page, entry requires at least 10 Google reviews, tables are reader-sortable, and the conflict of interest (Maijin, the editor, appears in the rankings) is disclosed on every page. Anyone can suggest a missing player via the on-page form. Version 0.4, July 2026. Available in FR, EN, DE, IT. - [Map of Swiss AI sovereignty](https://diagnostic-ia.ch/souverainete): an interactive map (French only) of 125 actors of the Swiss AI value chain across 10 links, from raw materials, components, logistics and electricity to telecoms, data centres and GPUs, hardware, cloud and software, AI models and research, and business support. Each actor has a dedicated page at /souverainete/ showing who controls it (type of ownership, US control and CLOUD Act exposure); each link of the chain has a page at /souverainete/maillon/ with its sovereignty score out of 5. Data as of 6 October 2026. - [Methodology](https://diagnostic-ia.ch/methodologie): how the diagnostic evaluates AI maturity: the eight dimensions, the four levels, and what the score is used for. - [Privacy / Confidentialité](https://diagnostic-ia.ch/confidentialite): how respondents' data is handled. ## About Maijin - [Maijin](https://maijin.ch): Swiss firm (Geneva) for AI transformation, training and outsourced Chief AI Officer services.
