Cleanpaste
Clean Paste is a text-cleaning utility designed to remove invisible characters (zero-width spaces, non-breaking spaces, soft hyphens, directional markers, stray control bytes) and watermark-style markers that AI models can embed in generated text. It is aimed at writers, marketers, engineers, reviewers, and teams who need predictable rendering in CMSes, email clients, docs, and code repositories. The product scans pasted or typed input, highlights hidden markers, strips and normalizes problematic code points, and returns cleaned text that preserves punctuation, grammar, and meaning.

Remove AI Watermarks
Detects and removes watermark-like sequences and hidden signatures that some AI models embed in generated text to trace provenance.
Clean Invisible Characters
Detects and strips zero-width joiners/spaces, non-breaking spaces, soft hyphens, directional markers, and stray control bytes that break rendering or indexing.
Bypass AI Detection
Aims to eliminate telltale markers used by AI-detection tools (e.g., GPTZero, Originality.ai, Turnitin) so cleaned text avoids false positives from those systems.
Preserve Text Quality
Normalizes spacing and removes hidden metadata while preserving the original wording, punctuation, and grammar.
Instant Processing & Pipeline
Runs a consistent pipeline: input collection (in-memory), detection, strip & normalization, integrity re-check, and output ready to copy or download.
Supported AI Model Signatures
Claims compatibility with watermark and marker formats from major AI providers (ChatGPT/OpenAI, Anthropic Claude, Google Gemini, GPT-4, Llama, Mistral, etc.).

Use Cases
Editorial and Content Teams
Paste copy from Docs, Word, or AI tools to remove invisible whitespace and soft hyphens so CMS previews and production rendering match consistently.
Developers and Documentation Writers
Normalize code snippets, commands, and stack traces before sharing in READMEs, docs, or chat to avoid hidden bytes that break linting or shells.
Marketing and Outreach
Polish email templates and sales scripts to ensure consistent rendering across Gmail, Outlook, and mobile clients by removing stray characters from PDF or AI exports.
Compliance and Review
Provide auditors and reviewers with text free of tracking characters or markers to reduce false flags in automated scanners and simplify audits.
Product and Support Teams
Prepare release notes, in-app copy, and ticket responses that retain consistent spacing and don’t break when pasted into chat widgets or UIs.
Academic and Research Workflows
Move citations, quotes, and tables between tools without carrying over zero-width characters to avoid layout drift when exporting to PDF or other formats.
