### 3/5 — Guter Ansatz aber unfertig

*2026-01-25*

Die App macht anfänglich einen guten Eindruck. Mir gefällt das User Interface sehr gut. Ollama und verschiedene Service-Provider lassen sich wirklich leicht und übersichtlich einrichten und verwalten. Die Kommunikation mit Ollama und den lokalen Modellen war ebenfalls problemlos. Mit der OpenAI API laufen nicht alle Modele. GPT-5-Chat geht, GPT-5.1-Chat geht nicht, 5.2 auch nicht. Der Chat selbst hat leider keine Markdown Umwandlung, MD wird also unformatiert angezeigt. Wenn der Entwickler die App pflegt kann daraus aber etwas gutes werden.
