Your text never leaves your browser.
Most online text tools send what you paste to a server. ClepBoard doesn’t. All the detection and cleaning happens on your device, which is exactly what you want when you’re checking emails, contracts or anything confidential.

Questions
What is ClepBoard?
A small set of tools for everything you copy and paste. The Cleaner reveals and removes hidden characters, AI leftovers and formatting junk. Commands gives you terminal commands that always copy clean. Pad keeps private notes in your browser.
Is my text uploaded or stored?
No. All detection and cleaning runs in your browser. Your text is never sent to a server. A draft is kept only in this browser tab’s session storage so a refresh doesn’t lose it; it disappears when you close the tab.
What is the X-ray?
A view of your text where every character you normally can’t see is shown as a labelled, colour-coded chip: purple for zero-width and control characters, orange for unusual spaces, red for look-alike letters and hidden messages. Hover any chip to see exactly what it is.
What are hidden prompt injections?
Instructions hidden inside text using invisible Unicode characters. People see nothing, but many AI models read them. ClepBoard decodes these messages so you can see them, and removes them from the clean copy.
Why do commands copied from websites break?
Blogs and word processors turn -- into an en dash and straight quotes into curly ones, and sneak in non-breaking spaces. Shells reject all three. Every command in ClepBoard is checked to copy as plain, clean text, and the Cleaner’s Code preset repairs commands copied elsewhere.
Can I paste AI answers into Google Docs with formatting?
Yes. Press "Copy as rich text" and ClepBoard converts the Markdown (headings, bold, lists, links, tables) into real formatting for Google Docs, Word, Gmail, Outlook and Notion.
Does it make AI text undetectable?
No. AI detectors judge wording, not characters, and we don’t think any cleaner can honestly promise that. ClepBoard makes text clean, consistent and safe to paste.
Who is Clep?
The little clipboard in the corner. He watches what you do, cheers when you copy, and panics when he spots hidden text. Click him for tips, or hide him from the ⌘K menu.
