About

memory.wiki Clipper

Features
Read full description

memory.wiki Clipper saves a web page, or a passage you select, as a clean, private memory.wiki link you can revisit later or bring into your AI assistant. Reading something worth keeping? Save it in one tap and get a tidy memory.wiki link. Open it anytime, or paste it into your own AI workflow (ChatGPT, Claude, Gemini, Cursor) instead of copy-pasting text. What it does: β€’ One tap saves the current page, or the passage you select, as a clean Markdown note at a short memory.wiki link. β€’ The link is copied to your clipboard, ready to revisit or share. β€’ Add a short note about why you saved it, before publishing. β€’ Sign in with your memory.wiki account to sync your saved pages across your devices. Privacy: β€’ The extension does not track you and does not sell data. β€’ A page is sent to memory.wiki only when you tap save.
