What this is
AcePaste Cleaner Pro is a privacy-first text cleaner. You paste text in, it strips out the invisible junk and the formatting noise, you copy clean text out. Everything happens locally in your browser — your text never crosses the network.
It exists because modern AI-generated text is increasingly carrying hidden Unicode payloads — zero-width characters, bidi overrides, U+E0000 "tag" characters, and other invisible glyphs that humans can't see but other AI systems will read and act on. Pasting that text into another AI, into a codebase, into a contract, or into a public post is how prompt-injection attacks and visual-spoof attacks spread. AcePaste removes those characters on every clean, with no opt-out.
What it cleans
- Invisible Unicode (zero-width, bidi overrides, variation selectors, tag characters, etc.)
- AI markup runs (##, ***, +++)
- Markdown formatting
- HTML tags and comments
- Smart-quote / em-dash / NBSP normalization to plain ASCII
- Emojis, dates, numerals, symbol-prefixed tokens — opt-in
- Custom find-and-replace rules with optional regex
How it's built
Static HTML, hand-written CSS, vanilla JavaScript. No frameworks, no build step, no analytics, no cookies on the marketing pages, no third-party scripts. AcePaste is free; an optional account (Supabase authentication) exists only to sync settings to the Chrome extension. The code is the same on the website and in the extension.
Who's behind it
AcePaste is built by ThinkWell Labs LLC, a small studio focused on privacy-first tools.
