Convert text to Unicode braille and back. Uses uncontracted (Grade 1) English braille: the 26 letters, digits with the number sign, capitals with the capital sign, and common punctuation, all output as Unicode Braille Patterns (U+2800–U+28FF) so they render anywhere. The to-braille endpoint turns ordinary text into braille; the from-braille endpoint decodes braille back to text. Unknown characters pass through unchanged. Perfect for accessibility tooling and education, labels and signage mockups, braille-display previews and learning resources. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Grade 1 only (no contractions). Distinct from cipher/alphabet encoders and from general text transforms.

See your colours the way colour-blind users do. Pass a hex colour (or a whole palette) and get back how it appears under each major colour-vision deficiency — protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind) and achromatopsia (total colour blindness) — as simulated hex and RGB values. Roughly 1 in 12 men and 1 in 200 women have some colour-vision deficiency, so this is ideal for accessibility testing of UI themes, charts, maps, status colours and branding: simulate your palette, spot colours that become indistinguishable, and fix them before you ship. Pure local matrix transforms — no key, no third-party service, instant. Live. 4 endpoints. Distinct from colour conversion and contrast tools.
