Whetstone
PromptLeadz · Your own AI assistant
Actually master the skill you keep meaning to learn.
Whetstone helps you actually master the thing you keep meaning to get good at, the language, the instrument, the craft, with deliberate practice instead of aimless repetition. Drop the file into ChatGPT, Claude, Gemini or Copilot and it runs as your practice coach. No login, no subscription.
Ten years of practice and no real progress usually means ten years of the same comfortable practice.
Do not take that on faith. Watch it run, then run it on your own skill.
Watch it run
The brief: you have plateaued on guitar after a year of playing the songs you already know.
Plain model
"Keep practicing regularly, learn new songs, and challenge yourself. Consider taking lessons or using online tutorials to improve your skills."
Whetstone
"Playing songs you already know is rehearsing, not improving. Find the one thing just past your reach, barre chords, or a tempo you keep fumbling, and drill only that, slowly, until the mistakes disappear, then speed up. Fifteen focused minutes on the edge of your ability beats an hour of comfortable strumming. Progress lives in the part that feels awkward."
Same plateau. The plain reply says practise regularly and challenge yourself, which is what kept you flat. Whetstone points you at the specific weak spot, has you drill it deliberately, and works the edge of your ability, which is the only place skill actually grows.
Then run it on your own skill
The file carries one command. Type prove it, describe your own skill, and Whetstone writes the plain advice next to its own, marks five checks you can confirm with your own eyes, and shows you the gap. On your skill, not a demo. If its version does not clearly win, you will see that too. It is built to show you the honest difference, not a score it handed itself.
What you are actually buying
A skill, not a prompt. Your AI runs it as its own assistant, in one file. Open it and it:
- Reasons from first principles instead of guessing at a format
- Checks its own work before it answers you
- Handles the hard cases, the ones with no obvious answer
- Holds its line when you push back
- Proves its own lift, any time you ask
That is the gap between this and the free prompt one tab over. It is why $9.99 is the floor.
Yours to keep
A file you own. It runs in any chat: ChatGPT, Claude, Gemini, any model. No login, no subscription, nothing anyone can switch off. Buy it once and use it on every skill you want to master from here on.
