As answered by people managing Project Euler and Toolworks.studio.
Toolworks.studio's answer:
We don't sell a product, we offer a free service.
Toolworks.studio's answer:
Early-stage YouTubers, Etsy sellers, and print-on-demand store owners — people doing the daily work of titling videos, pricing products, and writing listings, who want quick utilities rather than another subscription dashboard.
Toolworks.studio's answer:
Astro (static site generation), vanilla JavaScript — every tool is client-side pure functions, unit-tested with Vitest. No backend, no databases, no tracking; hosted on Vercel.
Toolworks.studio's answer:
Every tool runs entirely in the browser — nothing you type is uploaded, stored, or seen by anyone. No signup, no paywall, no "free trial" that ambushes your card. The math is honest, too: our calculators use real fee structures (Etsy's 6.5% + 3% + $0.25, Shopify's 2.9% + 30¢) and our YouTube earnings estimator gives honest ranges by niche instead of a fake-precise number.
Toolworks.studio's answer:
Most creator-tool sites gate their useful features behind subscriptions and bury free tools in ads and email-capture walls. Toolworks is free with no account, loads instantly (static pages, ~100KB images), and covers both sides of a modern creator business — YouTube packaging tools and Etsy/print-on-demand seller tools — in one place.
Toolworks.studio's answer:
Built by an independent creator who runs the same playbook: YouTube channels and an Etsy print-on-demand shop. The tools exist because we needed them — the fee math in the profit calculator is the math we run on our own products. Funded by clearly disclosed affiliated links instead of ads, so the tools stay free.
