MasterMyPrompt
Turn rough ideas into precision AI prompts
What it does
MasterMyPrompt doesn’t give you another prompt library—it turns your rough idea into a structured, model-optimized prompt in one step. You describe what you want; we add personas, context, and constraints and tailor the output for ChatGPT, Claude, Gemini, Perplexity, or Grok. No templates to browse, no prompt-engineering course required, just paste your thought and get a pro-grade prompt you can use immediately.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
