Memowise

Capture, organize, and actually remember what you read online

One-click highlighting anywhere

Select text on any web page and save it as a highlight via the right-click menu or a keyboard shortcut, with your own tags and notes attached at the moment of capture.

WeChat Read note integration

Capture notes inside the WeChat Read web reader and bulk-import every highlight from a whole book in one click, then review and reuse them organized by book.

Auto-tagging by source

Highlights taken on Weibo, Jike, X, and other social platforms are automatically tagged with their origin, so you can filter by channel later without filing anything manually.

Multi-dimensional filtering and search

Narrow your library by tag, keyword, folder, same source, or same domain to surface exactly the notes a given question or project needs.
