Invisible character detection
Scans for invisible Unicode code points, including zero-width spaces, joiners, no-break spaces, BOMs, and other ghost characters, then removes them while leaving visible words unchanged.
Overview
Clean Paste AI is an in-browser text sanitation tool for cleaning clipboard text before pasting it into documents. Its free tools remove invisible Unicode characters and Markdown residue so copied text can be turned into readable plain text without changing the visible wording.
The site positions the product for people working with AI-generated copy, documents, and publishing workflows. It emphasizes local browser cleaning for the free tools, residue counts for inspection, and optional Pro rewriting features for drafts that need semantic reconstruction rather than simple character removal.
Core capabilities
Markdown cleanup
Strips Markdown syntax such as headings, bold markers, blockquotes, links, and code fences so copied text becomes plain text ready for docs or publishing.
Local browser execution
Runs the free cleaning workflow in the browser, which the site describes as local and private for free tools, with no login required.
Residue inspection
Shows residue counts and itemized detection results so you can inspect what was found before cleaning or copying the output.
Pro rewriting tools
Includes Pro tools for Text Watermark Remover and AI Humanizer, aimed at drafts that need meaning-preserving rewriting rather than simple cleanup.
Workflow-oriented pages
Provides dedicated workflow pages for cleaning text copied from AI assistants and common document contexts such as docs, CMSs, email, and chat tools.
Common use cases
Publishing and docs cleanup
Clean AI-generated drafts before pasting them into Google Docs, Word, Notion, Webflow, or similar document and publishing tools so hidden characters do not affect formatting or search.
Editorial plain-text conversion
Strip Markdown wrappers from chat outputs when an editor or reviewer needs plain text instead of headings, bold markers, blockquotes, or code fences.
Ops and documentation workflows
Prepare support replies, release notes, and technical summaries for internal tools by removing zero-width characters and other clipboard residue that can break formatting.
Semantic rewriting for Pro users
Use the Pro features when a draft needs more than cleanup, such as rewriting text that contains watermarks in the wording or smoothing mechanical AI prose.
