BoxGrow — Textarea Auto-Grow & Pop-Out Editor

Auto-grow text boxes as you type, pop out into a full-page editor, and restore drafts after a reload. Nothing leaves your device.

BoxGrow makes cramped text boxes usable. Comment fields, support forms, and email composers stay tiny while your writing grows, and one wrong click or reload can wipe a paragraph of careful writing. BoxGrow fixes both problems on any site you use. What it does - Grows a focused text box as you type, capped at 80% of the window height, and never shrinks it below the size the site gave it - Pops out a calm full-screen editor from a small corner button or Alt+Enter, and syncs your edits back into the page, compatible with React and other frameworks - Keeps a local draft of each field as you type, and offers it back with a restore chip if a reload or mis-click loses your text - Steps back through edit snapshots inside the editor, so a bad paste or deletion is never final - Pauses per site from the popup, with global auto-grow and draft toggles in options that apply to open tabs without a reload Why it runs on all sites Text boxes live everywhere, on comment systems, forms, and web apps nobody can list in advance. BoxGrow's single purpose is making the field you are writing in usable, so its content script matches all URLs. It only touches fields you focus and does nothing until you type. Private by design BoxGrow makes no network requests of any kind. No analytics, no tracking, no account, no remote code. Drafts, settings, and your license stay in Chrome's local storage on this one device, and nothing ever leaves it. Free and Pro Free is useful forever: auto-grow everywhere, the pop-out editor with sync-back, 5-step undo, and 25 retained drafts.
