About

Finding out what font a page uses or what colour a button is shouldn't mean opening developer tools and digging through styles.

Serifio puts the answer next to the text. Select it and read.

No ads. No account. No paywall and no upgrade prompts. No analytics or tracking.

Serifio makes no network requests of its own and what you select never leaves your browser.

Serifio uses no third-party libraries or services. All of its code ships inside the extension and runs in your browser.

Before every release hundreds of automated tests drive a real copy of Chrome through selections, picks and copies.

Serifio is made in London by its founder, Mercurius Saad.
