About Plainso

What Plainso is

Plainso makes simple interactive tools for the web — calculators, estimators, and helpful utilities that people actually use. Every tool is free, fast, and works without an account.

Why embedding

Every tool on Plainso comes with embed code. A freelancer can add a rate calculator to their website, a startup can add a runway estimator, a designer can add a project quote tool. It helps their visitors before they ever get in touch.

What we believe

• • Small and useful — a single good calculator beats a platform that does everything
• • No accounts, no friction — tools should just work
• • Free first — the tools are free to use; embedding keeps them free with a small “Powered by Plainso” link
