InvisibleFix App
A clean-text layer for the AI era. Remove invisible Unicode characters, normalize formatting and publish platform-ready content without rewriting your message.
Built for social posts, SEO pages, newsletters, documentation and any workflow where AI-generated text is copied, pasted and shipped at scale.

Why clean AI text before publishing
AI tools generate great ideas, but copy-paste workflows introduce invisible Unicode characters and formatting noise. The result is unstable rendering: broken line breaks, glued emojis, weird spacing, truncated snippets and unpredictable behaviour across platforms.
The InvisibleFix promise
Clean the text, keep the message
InvisibleFix does not rewrite your content. It removes invisible characters and normalizes formatting so the text behaves like native writing everywhere it is pasted: social platforms, CMS fields, email layouts and documentation tools.
3
core actions
Detect invisible Unicode, normalize spacing and enforce platform-aware rules before you publish.
2
ways to use it
Web App for desktop workflows and iOS Keyboard for cleaning inside any mobile app.
1
shared engine
A single sanitization engine that keeps results consistent across tools and platforms.
What the app does
InvisibleFix cleans AI-generated text at the Unicode level. It removes the invisible characters that break layouts and normalizes formatting so your content renders predictably across platforms.
How it works
A simple workflow on the surface, a deterministic engine underneath. Clean once, then publish anywhere with confidence.

1. Paste or type
Bring text from ChatGPT, Claude, Gemini, Docs, PDFs or any editor into InvisibleFix.
2. Choose a destination
Select SEO, LinkedIn, TikTok, Instagram, X, Facebook or Email to apply platform-aware rules.
3. Clean and publish
Copy cleaned text into your app, CMS or scheduler with predictable rendering and stable formatting.
Under the hood
A deterministic sanitization engine, not a rewrite tool
InvisibleFix operates at the Unicode layer. That means the result is predictable and repeatable: the same input produces the same cleaned output, without “creative” changes to your wording.
Detection layer
Scans text for invisible Unicode characters and control marks that impact rendering, search fields and social parsing.
Normalization layer
Applies safe replacements for spaces, line breaks and punctuation, while preserving meaning, tone and structure.
Stability checks
Ensures the cleaned text behaves in real fields: feeds, captions, bios, titles, meta descriptions and email layouts.

Two products, one standard of clean text
Choose the interface that fits your workflow. Both are powered by the same sanitization engine so results stay consistent across devices and teams.
Platform profiles: one engine, multiple publishing surfaces
A LinkedIn post does not behave like a meta description, and a TikTok caption does not behave like an email preview line. Platform profiles encode these differences so teams do not have to remember them manually.
SEO & web profiles for titles, headings, body copy and metadata
Social profiles for LinkedIn, TikTok, Instagram, Facebook and X
Email profiles for subject lines, preview text and newsletter layouts
Generic profile for documentation, notes and internal tools

Use cases
Agencies & ghostwriters
Deliver polished assets to clients without spending hours fixing spacing issues at the end of the process. Keep the voice, remove the invisible problems.
SEO & content operations
Normalize hundreds of AI-assisted articles and metadata fields so snippets, headings and internal search behave predictably in your CMS.
Creators & teams on mobile
Clean captions, bios and replies directly inside mobile apps using the iOS Keyboard. Avoid weird wraps and broken hashtags when publishing fast.
App FAQ
Quick answers about what InvisibleFix changes (and what it never changes).
Does InvisibleFix rewrite my content?
No. InvisibleFix removes invisible Unicode characters and normalizes formatting. It does not paraphrase, summarize or change meaning.
What kind of characters do you remove?
InvisibleFix targets Unicode-level noise: zero-width characters, NBSP, BOM, Bidi controls and other control marks introduced by AI tools, PDFs, Docs and chat apps.
Will this help with hashtags and emoji spacing?
Yes. Many hashtag and emoji issues come from invisible spaces and zero-width marks. Cleaning stabilizes how platforms parse and render your text.
Web App vs iOS Keyboard: which one should I use?
Use the Web App for desktop workflows and long form content. Use the iOS Keyboard to clean text inside any mobile app. Both share the same engine.
Is InvisibleFix only for AI-generated text?
No. Any text copied from Docs, PDFs, email or chat tools can carry invisible characters. Cleaning improves predictability even for human-written content.
