PromptCraft distills the best practices of LLM craft into small, daily learnable moments. Start as a beginner, leave an AI power user.
"The most important skill in the AI age is learning how to actually work well with AI systems."
Everyone uses ChatGPT, Claude, Gemini. Almost everyone uses them badly. They write one-sentence prompts, get mediocre outputs, and conclude AI is overrated.
Meanwhile, the people who actually understand how to prompt, how to chain reasoning, how to use tools, how to evaluate outputs — they're 10x more productive. That gap is the opportunity.
PromptCraft closes it. We take the best practices from the research community and from builders like Karpathy, and we make them learnable in daily 3-minute sessions.
We didn't just copy Duolingo and swap the subject. We built this from scratch for how AI actually works.
Not just exercises with right answers. We use LLMs to evaluate your prompts and show you exactly why one version outperforms another.
Our system understands the LLM domain deeply — concepts, relationships, techniques. It gets smarter as more people learn from it.
New model capabilities, new techniques, new pitfalls. PromptCraft updates with the field — the knowledge graph grows as AI itself advances.
Real progress, not bloated courses. One concept, one challenge, one insight. Every session fits into a coffee break.
From "how do I write a better ChatGPT prompt" all the way to agentic engineering, multi-model orchestration, and evaluation strategies.
Core skills are always free. Premium unlocks advanced techniques, personalized coaching, and the knowledge graph's deepest layers.
A real-world scenario: "Write an onboarding email sequence" or "Debug this Python function" or "Summarize this research paper."
No coding required. You write a natural language prompt that would get the best possible output from an LLM for that scenario.
Not just "right or wrong" — a detailed breakdown of why your prompt works or doesn't, with a scored improvement and a reference to the technique being practiced.
Streaks, badges, skill trees, leaderboards. The engagement mechanics of Duolingo applied to a domain that moves 10x faster.
The people who get good at this
Not because they're smarter. Because they know how to work the machine. PromptCraft gives you that skill — one 3-minute session at a time.
