Invisible Character

Invisible Character is a free browser tool for copying and generating invisible Unicode characters and blank text. One-click presets cover Hangul Filler (U+3164) for blank game and Discord names, Braille Blank (U+2800) for empty WhatsApp messages and Instagram line breaks, zero-width space and non-breaking space. Generate 1 to 10,000 characters at once and test them in the built-in checker; nothing is uploaded. The site also offers AI writing tools (humanizer, paraphraser, grammar checker and summarizer) with a free tier and optional paid plans.
