Skulk Operator vs Tersa

Skulk Operator is the native remote control for a user-owned Skulk distributed AI cluster. Pair the app with a cluster to: • View cluster health, topology, memory utilization, and node status. • Browse the model catalog and the cluster’s canonical model store. • Inspect model availability across nodes and preview recommended placement. • Place models on compatible compute and stop running instances. • Chat with ready text models while keeping conversation history on this device. • Track downloads, placement, loading, and other operator activity. • Review connection status and paired devices. The normal remote path uses an end-to-end encrypted relay. Foxlight’s relay forwards encrypted traffic without access to operator commands, model details, prompts, or responses. Credentials use platform secure storage, and conversation history remains device-local. Skulk Operator does not download or run AI models on your iPhone or iPad. A separately installed and running Skulk cluster is required. Skulk is free and open-source software.

Tersa is a touch-first workspace for learning, reviewing, and tuning small analog and RF circuits on iPhone and iPad. Build editable schematics, configure DC operating point, DC sweep, AC and transient analyses, and inspect measurements on clear plots. For linear two-port work, review S11, S12, S21 and S22, return and insertion loss, and raw complex data on a Smith chart. Use local sample projects to explore RC and LC filters. Change supported component values with the tuner and run the analysis again without rebuilding the project. Import supported SPICE model cards and subcircuits when a circuit needs them. Simulation runs locally on the device. Results depend on the circuit, models, and numerical settings and must be independently verified before fabrication or safety-related use.
