Clean AI text before you publish

InvisibleFix removes invisible Unicode characters and normalizes formatting so your content renders predictably across social platforms, CMS fields and SEO metadata.

01

Why InvisibleFix exists

Invisible Unicode characters such as NBSP, zero-width spaces and directional marks are increasingly common in AI-generated text and often go unnoticed until they break real layouts.

AI copy-paste brings invisible noise

AI tools and editors often introduce invisible Unicode characters (NBSP, zero-width, Bidi marks) that silently break formatting once you paste into real platforms.

Platforms render text differently

A caption on TikTok does not behave like a LinkedIn post, and neither behaves like a meta description. One hidden character can change wrapping, spacing and parsing.

Formatting impacts reach and trust

Broken line breaks, glued emojis and unstable hashtags reduce readability and engagement. In SEO fields, Unicode noise can also affect snippets and indexing behaviour.

The bugs are hard to diagnose

Because the characters are invisible by design, teams often discover the issue too late: after publishing, after scheduling, or after a client review.

One clean version of your text

InvisibleFix acts as a hygiene layer between AI tools and publishing. It cleans text at the Unicode level, normalizes spacing and keeps your wording unchanged, so you can ship consistent content everywhere.
