EditorJS | AI Text Plugin

While you write in Editor.js, the plugin waits for a pause (two seconds by default) and offers how the paragraph could go on, in pale grey after the cursor. Tab or Alt takes it; Escape or Backspace turns it down. You can change both the keys and the delay.

It doesn't call a model by itself: you hand it a callback that gets the paragraph's text and returns a promise of the suggestion, so the request goes through your own backend to whatever model you use. It is built on Editor.js's default Paragraph tool, and what it saves is a block of plain text.
