Like Cookpad,
but for AI prompts.
HOWAI is a community where people share step-by-step AI workflows as “recipes” — complete with prompts, expected outputs, and a reproducibility score so you know what actually works before you try it.
The Problem
You find a promising AI prompt online. You try it. It doesn't work. Sound familiar?
Most AI tips scattered across Twitter threads and blog posts have no signal on whether they still work, which model they were tested on, or whether anyone else has actually reproduced the result.
The Reproducibility Score
Every recipe on HOWAI has a reproducibility status, automatically calculated from community practice reports. You can instantly see how reliable a recipe is before investing your time.
How It Works
Find a recipe for what you want to do
Search by goal, AI tool, or difficulty. Filter by reproducibility to find recipes that reliably work.
Copy the prompt and run it
Each recipe includes a ready-to-use prompt, step-by-step instructions, an example output, and tips. Copy, paste, and go.
Leave a practice report
Did it work? Leave a report. Your feedback updates the reproducibility score and helps the whole community.
Three Recipe Formats
Designed for how AI is actually used
A single prompt that gets the job done. Best for quick, focused tasks.
e.g. Summarize a meeting in 3 bullet points
A sequence of prompts for complex workflows. Follow each step in order.
e.g. Research → Draft → Refine a blog post
A branching workflow with decision points. For adaptive, multi-path tasks.
e.g. Debug code with conditional paths
Why HOWAI, Why Now
AI adoption is accelerating
Millions of people want to use AI in their daily work but don't know where to start. HOWAI gives them a trusted, curated starting point.
Prompts need provenance
As AI tools evolve, knowing which prompts work — and on which models — becomes critical. The reproducibility score solves this.
Communities outperform algorithms
The best prompts come from real people solving real problems. HOWAI surfaces collective intelligence, not just search rankings.
Built for non-engineers too
You don't need to code or understand transformers. If you can follow a recipe, you can use HOWAI.
