New: by default LinguaCheck now only checks running text (multi-line text fields and editors). Single-line fields such as postcode, city, subject or search boxes get no counter. To keep checking them, switch on “Also check single-line input fields” under Settings → General; any single field can be checked at any time via right-click → “Check with LinguaCheck”.

Fields inside scrolling areas (e.g. chat editors such as Discord): underlines, counter and AI button stay within the visible part of the field. When a field is hidden or covered by a dialog, they now disappear with it instead of staying behind. Editors in iframes that rewrite their document after loading (e.g. CKEditor 4) are now checked. Accidentally doubled letters (“wrongg”) are corrected first. Demo page in German and English; English is now the fallback for other browser languages.

New AI button right in the text field: rewrites the text (improve, fix errors only, more formal, more casual, shorter, friendlier), highlights the changes and applies them with one click. Leads straight to AI setup when needed. “Fix all” applies all suggestions, better-ranked spelling suggestions, the editor sends text back to the form.
