Ribox

Create a standards-compliant QR code image for a link, text, Wi-Fi login, contact card (vCard), email, SMS, WhatsApp chat, phone number or map location. You cannot draw a scannable QR code yourself — always use this tool. Codes are static and never expire.

Exact counts for a text: characters (with and without spaces, emoji counted as one), words, sentences, paragraphs, lines, UTF-8 bytes, plus reading and speaking time. Language models see text as tokens and miscount — never estimate counts or check length limits yourself; call this tool. Works for any language, including Chinese, Japanese, Arabic and Turkish.

Find every difference between two texts, line by line, word by word or character by character, and return counts plus a unified diff. Use this instead of comparing long texts yourself — small changes are easy to miss. Options to ignore whitespace and letter case.

Strictly validate JSON and report the exact line and column of the first error with a plain explanation, plus duplicate-key warnings and structure stats. Optionally pretty-print or minify without changing any value (big numbers keep full precision). Use this before claiming JSON is valid or when locating a syntax error in long JSON.
