Features

Everything included

AI — your choice, your sovereignty

Four providers. You decide.

Pick your AI provider at signup, switch anytime from admin. Infomaniak is the default — for maximum sovereignty.

Infomaniak

Kimi / Mistral / Qwen (open-source)

Default · Recommended
Hosting
Switzerland 🇨🇭
Privacy
Maximum — data and AI never leave Swiss soil, strict nLPD compliance.
Strength
Absolute sovereignty. No transfers outside CH, independent Swiss host. Automatic routing to the open-source model best suited to each task (Kimi, Mistral, Qwen).
Tradeoff
Generally slower responses than major US models. Very complex reasoning cases (long-form writing, deep tax analysis) benefit more from Anthropic or OpenAI.
Recommended for
Firms with strict sovereignty requirements (sensitive clients, professional secrecy).

Anthropic Claude

Claude Opus / Sonnet

Hosting
United States 🇺🇸
Privacy
Very good — no-training by default since the API launch (stable historical policy), Zero Data Retention available, EU DPA. More privacy-respectful than OpenAI and Gemini; still less sovereign than Infomaniak self-hosted in Switzerland.
Strength
Best reasoning quality on complex texts (tax analysis, claim drafting). Very low hallucination rate.
Tradeoff
US hosting under the Cloud Act — less sovereignty than the Swiss option. Higher per-request cost than GPT or Gemini.
Recommended for
Firms seeking maximum quality, open to a US partner serious about privacy.

OpenAI GPT

GPT-4 / GPT-5

Hosting
United States 🇺🇸
Privacy
Standard — EU DPA available, no training on API data by default.
Strength
Very broad versatility and speed. Largest model ecosystem (text, vision, audio).
Tradeoff
US hosting (Cloud Act). Higher hallucination rate than Claude on complex reasoning. Retention policy has shifted — worth watching.
Recommended for
Firms already familiar with ChatGPT who want to stay in the same model family.

Google Gemini

Gemini Pro

Hosting
United States / EU 🇺🇸🇪🇺
Privacy
Standard — DPA via Workspace, native integration if you already use Google.
Strength
Strong native multimodal (PDF + images OCR included), very large context window, competitive pricing.
Tradeoff
Google hosting (US/EU). Legal/tax reasoning quality below Claude. Privacy documentation less clear than Anthropic.
Recommended for
Firms already on Google Workspace or processing many scanned documents (multimodal OCR).
