What Claude Pro does well
- Claude Code, Anthropic’s coding agent for the terminal, is included from the Pro tier at €18 a month excl. tax, with usage limits shared between Claude and Claude Code.
- A free tier with no credit card: chat on web, iOS, Android and desktop, a 200k-token context window, web search, memory, projects and code execution. As of August 2, 2026, the pricing page we reviewed mentions reduced weekly limits on this tier.
- As of August 2, 2026, the privacy center we reviewed states that consumer conversations are used to improve the models only if the user explicitly turns on the setting, and that incognito chats are never used for this.
- Creation and editing of Word, Excel, PowerPoint and PDF files through code execution, including on the free tier according to the pricing page we reviewed.
- Interface and help center available in French, and broad office integrations: Slack, Google Workspace, Microsoft 365, Outlook, a Chrome extension and MCP connectors.
What Moon AI does differently
- Moon AI gives you more than 100 models from several companies in one subscription: GPT (OpenAI), Claude (Anthropic), Gemini and Gemma (Google), DeepSeek, Mistral, Llama (Meta), Grok (xAI), Qwen (Alibaba), Command R+ (Cohere), Kimi (Moonshot), MiniMax, plus Moon 6, the in-house model. Claude Pro gives access to its own company’s model family.
- Moon AI shows its prices in euros, VAT included, per seat per month: Lune €9.90, Étoile €19.90, Constellation €49.90, Galaxie €89.90, Univers €249.90, with 20% off each extra seat in the same workspace and no commitment. As of November 6, 2026, Claude Pro is listed at €18 a month excl. tax, so €21.60 with 20% VAT.
- Moon AI’s app and storage are hosted by OVHcloud in Strasbourg and Roubaix. Requests sent to third-party models go through Moon Blur first, which masks the sensitive data it detects. As of August 2, 2026, the Anthropic privacy policy we reviewed states that data is processed and stored in the United States and other countries outside the EEA, under the European Commission’s adequacy decisions and the standard contractual clauses of Article 46 of the GDPR.
- Moon Blur applies two-way reversible masking to the sensitive data it detects before sending to third-party models: more than 150 categories (French social security numbers, IBANs, payment cards, addresses, health identifiers, tax numbers, license plates), then puts the real values back in the response.
- Moon AI offers agents and routines (scheduled or triggered by webhook), dozens of connectors (Gmail, Slack, GitHub, Notion, Stripe), Word, PDF, Excel and PowerPoint document generation, native iOS and Android apps, Moon CLI, and an interface and support in French. Claude also offers creation and editing of Word, Excel, PowerPoint and PDF files, the Claude Code agent in the terminal and integrations with Slack, Google Workspace, Microsoft 365 and Outlook.
Limits to know about
Facts you can check on the company’s public pages, not value judgments.
- The subscription gives access to models from a single company: as of August 2, 2026, the pricing page we reviewed lists Fable, Opus, Sonnet and Haiku, with no third-party models.
- As of November 6, 2026, the French-language pricing page shows prices in euros, excluding tax: “Prices shown do not include applicable taxes.” Applicable taxes, including French VAT, are added at checkout.
- As of August 2, 2026, the privacy policy we reviewed states that personal data is transferred to servers in the United States or other countries outside the European Economic Area. The platform documentation we reviewed only offers “us” as the storage region for data at rest, and “us” or “global” for inference.
- Usage is capped by limits shared between Claude and Claude Code. Beyond them, you can keep going with optional extra usage, turned on in settings and billed at standard API rates, with a configurable monthly spending cap.

On Anthropic’s side, the privacy policy reviewed on August 2, 2026 states that personal data is transferred to servers in the United States or other countries outside the European Economic Area, under the European Commission’s adequacy decisions and the standard contractual clauses of Article 46 of the GDPR.
Is there a coding agent in the terminal on both sides?
