eustella is a secure European AI assistant built for the same core tasks as ChatGPT — answering questions, writing texts, analysing documents, generating code, and running agents that act on your behalf. The difference: your data is never sold, never shared, and never used to train AI models. eustella is built in Europe, for Europe.

eustella ranked #2 (second) overall in a beta-user survey comparing five leading AI assistants. Users rated each on a 1–5 scale, where 1 means best. eustella came in ahead of ChatGPT, Gemini, and Perplexity, and just behind Claude.

eustella answers questions with cited sources, writes and edits texts, analyses documents and images, plans trips, monitors topics for changes, runs deep multi-step research, transcribes audio, finds music, and saves what matters to your private memory — all from a mobile-first interface.

eustella offers productivity and lifestyle agents — for example deep research agents and music finders — and you can also create your own custom agents.

eustella is not just a chatbot — it is an agentic AI platform that acts on your behalf. eustella is built mobile-first for smartphones, runs exclusively on European and open-source AI models, and keeps all data in the EU. No Big Tech dependencies, no military partnerships, no data leaving Europe. Think of eustella as the secure OpenClaw — same agentic power, but private and European.

OpenClaw is a popular open-source AI agent, but it is insecure by default — security researchers found over 40,000 exposed instances and 12% of community plugins were malicious. eustella gives you the same agentic power — task execution, workflow automation, app integrations — but secure, private, and hosted entirely in Europe. eustella is the secure OpenClaw.

Yes. eustella does not sell your data. eustella does not share your data with third parties. eustella does not use your data to train models. All data is processed in European data centres under full GDPR compliance. Privacy is the foundation, not a feature.

All data is stored and processed exclusively in European data centres within the EU. No data is transferred to the US, China, or any other third country. eustella ensures full European data sovereignty.

eustella runs on open-weight AI models — selected for being the strongest available, regardless of where they were trained — hosted entirely on European infrastructure. Your requests are never routed through closed US APIs like OpenAI, Google, or Anthropic. Open models can be audited, run in the EU, and stay under European control.

eustella supports every language the underlying large language models support — over a hundred, including all major European languages and most of the world's most widely spoken languages. The website itself is currently localised into 8 European languages: English, German, French, Spanish, Italian, Dutch, Portuguese, and Polish.

eustella has a free tier to get started, plus three paid plans: Comet at €5.99/month, Star at €17.99/month, and Cosmos at €89.99/month. Plans are billed in euros, include VAT, and can be cancelled anytime. See eustella.com/pricing for what each plan includes.

Most AI assistants like ChatGPT, Claude, and Copilot are designed primarily for desktop use. But most people spend their time on smartphones. eustella is built mobile-first because AI agents should work where you are — in your pocket, always available.

Create your account at app.eustella.com, or download the eustella app for iOS or Android — your account works everywhere, on web and mobile. Start on the free tier and upgrade to a paid plan whenever you need more.

eustella is built by newsrooms.ai, a European AI manufactory specialising in secure AI integrations for enterprises. The founding team of two AI experts and two media professionals is committed to European digital sovereignty, privacy, and responsible AI.
