5 AI toolsof the week

Text, design, data / knowledge, research and agents: one tool each, checked for value, cost and data protection.

This week shows a clear trend: on-device AI and EU-based tools are gaining ground. Proofly shows that professional AI features are possible without the cloud, while Nume, an EU start-up, stands out with GDPR compliance. At the same time, several innovative US tools (Bloom, Exa, Notis) show gaps in data protection.

This issue dates from before the English edition launched in October 2026. Summaries and short descriptions are translated; the detailed reviews are available in German. Detailed review in German →
