Four tools

One job, done cleanly.

Separate programs instead of one overloaded suite. You only buy what you need.

Culling & models

Klarschliff Foto-Studio

Cull and manage your shoots in one window. Sharpness is measured on the face, not on the whole image – so what's left is the sharp gaze, not the sharp background.

Monitor your GPU

Klarschliff GPU-Wächter

Many tools show temperature and watts. The guard also shows the current in every single pin of the power connector – the spot where expensive cards melt. It warns before anything smells.

  • Headroom to throttling
  • History & CSV
  • Power limit
