划懂: An AI Reading Layer for macOS

Editorial interest 84/100 Selection signal · not a rating of the site

划懂 explains selected text beside whatever you are reading, using a keyboard shortcut, browser session, or your own model API key.

Landing page captured for the 2026-09-21 issue.

For: Mac readers working through unfamiliar text
Worth noticing: Two operating modes: browser sessions without an API key, or an API-powered floating card with streaming output.

Field notes

The app separates model access into a browser-session mode and an API floating-card mode. The first reuses an existing 豆包 or DeepSeek web login without an API key; the second sends selected text and a prompt to a chosen provider, stores the key in macOS Keychain, and streams the answer beside the source. The page also documents a clipboard fallback for users without Accessibility permission and gives manual Chrome extension loading steps.
