Built by an ADAS engineer tired of gut-feeling car purchases.
Demo phase — feedback welcome.
HOWAI is what Cookpad did for cooking — but for AI prompts.
A community where people share step-by-step AI workflows, rated by everyone who tries them. Each recipe gets a reproducibility score— HIGH, USER REPRODUCED, or NEEDS UPDATE — so you know what works before wasting your time.
Try a recipe, leave a practice report. The score updates automatically. Good prompts rise. Outdated ones get flagged.
Built in Japan. Launching here to see if the concept travels.
