Frequently Asked Questions
Do I need to sign up to use Readability Checker?+
No. Every tool on TypoStudio.tools works fully in the browser with no account, email, or key required.
Is my input text stored anywhere?+
No. All processing runs locally in your browser. Nothing is uploaded, logged, or shared with a server.
Why does the preview look slightly different from my design app?+
Browsers render fonts and effects through their own engines. Small differences in hinting, subpixel rendering, and available fallback fonts can shift the visual result. Use the exported CSS or Unicode string in your target environment for the true output.
Can I use the output commercially?+
Yes. Generated Unicode text and CSS snippets are yours to use in commercial and personal work with no attribution required.
Which browsers are supported?+
The latest two versions of Chrome, Edge, Safari, and Firefox on desktop, tablet, and mobile.
Some characters look like empty boxes on my device — why?+
Certain Unicode mathematical or squared characters need OS-level font support. If your device lacks a font that covers the range, the glyph falls back to a tofu box. Switch to a different device font or a style with wider coverage (Bold, Italic, Fullwidth).
Can I share the exact settings with a teammate?+
Copy the generated string or CSS block and paste it into any editor — the effect is self-contained.
Does the tool work offline?+
Once the page has loaded, most tools continue to work without a network connection because processing runs client-side.
