What we take away from it

What counts in its favor

  • The price is public and easy to read: 14.99 € per month for unlimited access, with no commitment. It's the lowest rate of all the French legal assistants in this comparison.
  • Anthropic contractually commits not to train its models on data sent via the API: the questions you ask aren't used to improve Claude.
  • Three specialized modes (Tax, Administrative, Business Diagnosis) cover the most common needs of a small-business owner.

What counts against it

  • Data is hosted in the United States (Vercel, Supabase, Anthropic): for a professional bound by confidentiality, that's this solution's weak point.
  • The service is recent — the company LegArx was registered in 2026 — and the user volume isn't disclosed: there isn't much track record yet.

An excellent entry point for a micro-business owner who wants to try legal AI with no commitment and no significant budget. Not advisable if hosting outside the EU is a dealbreaker for your business.

ArxyA in detail

ArxyA is an AI assistant developed by LegArx, a company based in Tours founded in 2026. It targets owners of French micro-businesses and SMBs who have neither an in-house legal department nor a budget for a subscription costing several hundred euros a month, but who regularly need reliable answers on their taxes, accounting or administrative obligations.

What it actually does

ArxyA works in three modes. Tax mode answers questions on VAT, corporate tax, social contributions and tax optimization by drawing on the Bofip and URSSAF circulars. Administrative mode covers setting up a business, legal structures, employment contracts and registration procedures. Business Diagnosis mode asks seven questions about your structure, expenses and profits, and identifies areas for optimization.

A business owner might, for example, ask "how much will I actually take home net if my revenue is €80,000 in an EURL taxed on profits" and get an instant calculation, with no account required. The platform runs on Anthropic's Claude API, meaning the underlying AI model is the same one that powers general-purpose assistants — but ArxyA constrains it to draw on thirteen official French sources rather than the open web.

Why it interests us

The first strength is price. At 14.99 € per month with no commitment for unlimited access, ArxyA is by far the most affordable legal assistant in this comparison. For a freelancer or a micro-business billing 50 € an hour, the tool pays for itself the first time a question saves a trip to the accountant.

The second is transparency on training. Anthropic contractually commits not to use data sent via its API to train its models. That's a stronger guarantee than what most consumer-facing interfaces offer, even though it depends on a third party's commitment rather than a policy specific to ArxyA.

Where it falls short

The weak point is hosting. Every subprocessor — Vercel for the application, Supabase for the database, Anthropic for the AI, Stripe for payments — is based in the United States. Standard contractual clauses and the Data Privacy Framework govern these transfers, but for an accountant or a lawyer bound by professional confidentiality, the lack of hosting in France or the EU is a real issue.

The other reservation is the product's youth. LegArx was registered in 2026, the service has no public user volume yet, and there isn't enough track record to assess answer quality over time. That's not a dealbreaker, but it's worth keeping in mind.

Our recommendation

ArxyA is the right choice for a small-business owner who wants to discover what AI can bring to their tax and administrative management, with no budget and no commitment. If hosting in the United States isn't an issue for your business, the value for money is excellent. If, on the other hand, your data is covered by professional confidentiality, look instead at GenIA-L or Wisetax, both hosted in France.

Who it's for, and who it isn't

Suited for

  • Owners of micro-businesses and SMBs with no in-house legal department looking for quick answers to common questions
  • Professionals who want to try tax and accounting AI with no commitment, at a rate under 15 € per month
  • Business founders who need an assistant for administrative procedures and tax simulations

Not a fit

  • Regulated professions whose duty of confidentiality requires hosting in France or the EU
  • Medium or large firms that handle large volumes and need a tool proven at scale
  • Tax specialists working on complex structures that need the depth of sources only a publisher like Lefebvre Dalloz can offer

Frequently asked questions

Is ArxyA reliable on legal matters?
ArxyA runs on Anthropic's Claude and cites thirteen official French sources (Bofip, Légifrance, URSSAF circulars). Answers are sourced, but the vendor states they don't amount to personalized legal advice: they must be checked before any decision. It's an assistant, not a lawyer.
Is my tax data protected?
Data is encrypted in transit (HTTPS/TLS) and access is restricted to authorized staff. However, every subprocessor is based in the United States: data transits and is stored outside the European Union. Contractual safeguards (standard clauses, DPF) govern these transfers, but hosting isn't in France.
What's the difference between ArxyA and GenIA-L?
Price and depth. ArxyA costs 14.99 € per month for unlimited access, while GenIA-L starts at 213 €. But GenIA-L draws on the Lefebvre Dalloz publishing archives — 200 years of legal scholarship — and its servers are in Europe. ArxyA is a good entry point; GenIA-L is the production tool. It all depends on your consultation volume and your hosting constraints.
