We kept running into the same annoyance: every tiny AI task seemed to need its own app, its own account and its own subscription. So we put the tools on one website instead.
Knowyx (https://knowyx.com/) currently hosts 67 small tools across ten categories — food, photo, work, writing, learning, health, family and more. A few examples:
- Calorie Scan: estimate a meal's calories and macros from a photo (shows a confidence indicator; photo estimates usually land within about 15–25%)
- Photo Restoration and Photo Colorizer for old family photos
- Resume Tailor Optimizer: tailors a resume to a specific job posting
- ID Photo Maker, Image Upscaler, Homework Checker, Plant Doctor
Design choices we made:
- One shared credit balance across every tool instead of per-tool subscriptions
- Price shown before each run, and failed runs refunded automatically
- Most tools can be tried once for free without an account; registration gives 40 free credits
- Trilingual interface: English, Spanish and Simplified Chinese
Stack notes: everything is web-based, no downloads; each tool is a small server-backed workflow behind a shared credits/ledger system.
Feedback welcome — especially on which tool categories we're missing.
