What it does

Patronus is an AI firewall that runs on your laptop. It sees AI traffic across browsers, IDEs, native apps, and MCP servers — and lets you set policies per app. Local-first by design. Free public alpha. Built in Regensburg.

Die On-Device AI-Firewall zeigt jede KI-Nutzung, hält sensible Daten auf dem Gerät und liefert Nachweise für den EU AI Act. Jede KI. Deine Regeln.

Sieh, welche KI-Tools im Unternehmen wirklich laufen. Sensible Daten bleiben auf dem Gerät, nicht beim Anbieter. Der Nachweis für den EU AI Act entsteht nebenbei. Gefördert über Kickstart @ OTH, Mitglied im AIRCluster und präsentiert am RCAI Day 2026 der OTH Regensburg. Unsere Partner und Verbindungen → In einem typischen Mittelständler laufen über 20 KI-Tools. Freigegeben sind zwei. Preislisten, Konstruktionsdaten, Personalakten, Quellcode. Einmal eingefügt, verlassen sie das Haus. Der EU AI Act verlangt, dass du deine KI-Nutzung kennst und protokollierst. Eine alte Excel-Liste genügt nicht. Eine kleine Software auf dem Firmenrechner sorgt für drei Dinge, ohne dass jemand seine…from patronus.studio

    AI that actually controls your Windows/Mac desktop - clicks, types, automates workflows across any application. Native OS integration, not cloud APIs. Built this because I was tired of AI that could only chat. Free tier (Gemini) + paid tier (Claude) for reliable automation. The AI can automate complex workflows, manage files/emails, control browsers and native apps. Just launched 2 weeks ago. What workflows would you want automated?

  • Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
