Chat, images and voice in one AI workspace

Hertz is the KucLab AI workspace: chat, code, image generation and speech, with projects that keep their own context. Models are served through our API, so an account is required. Everything you send is zero-knowledge and we cannot read it.

About KucLab

An independent project: web apps, games and AI tools. No corporate talk.

Model training

We train our own models on Google Cloud, on A100 and H100 GPUs.

AI

Gemini 3.5 Pro with a 2M context window, plus Flash. Our own integration, for more freedom.

Search

Vertex AI Vector Search for semantic lookup. Anonymous, fast, and no query is stored.

Google Cloud is where we train models, not where anything you see here is hosted.

As a member of the Google Cloud Success Program we work directly with Google's engineers, which is where our model training access comes from.
