Features
eustella is a European agentic AI platform built by Vienna-based AI Newsrooms Technology GmbH, positioned as a sovereign alternative to US-based chat assistants.
The platform runs open-weight and European foundation models such as Mistral, Qwen, Whisper, and GPT-120B OSS self-hosted without external API dependencies across IONOS (Berlin), Verda (Helsinki), and Scaleway (Paris) data centers.
Beyond chat responses, the agent actively handles tasks including research, scheduling, and document analysis, with upcoming MCP connectors and native mobile apps on iOS and Android alongside the web app.
- Sovereign EU infrastructure on IONOS (Berlin), Verda (Helsinki), and Scaleway (Paris) without US CLOUD Act
- Open-weight model stack (Qwen, Mistral, Whisper, GPT-120B OSS) hosted entirely inside the EU
- Agentic platform: Acts and executes everyday workflows rather than being just a chatbot
- Mobile-first focus with native iOS and Android apps alongside the web interface
- Permanent Free tier plus monthly cancellable plans starting at €5.99/month
