HeyZenek: AI Writing Assistant — Rewrite, Summarize & Translate Text

Select text on any page: rewrite, fix grammar, summarize, translate or explain it with AI — 120+ tools, results in place.

HeyZenek puts a small toolbar next to any text you select in the browser. Reading an article, writing an email, reviewing a document in a web app — select the text, pick a tool, and get the result in place. No copying into another tab, no losing your place. WHAT YOU CAN DO • Improve — cuts filler and smooths clumsy sentences, keeping every fact • Correct — fixes grammar, spelling and punctuation without touching your style • Shorten — from a one-sentence TL;DR to a trimmed version of the original • Translate — into any language, keeping tone and natural phrasing • Explain — plain-language explanation of a difficult passage • Tone and formality — same message, different register • Notes, outlines, main points, titles — turn long text into something you can act on Over a hundred tools in total, and the toolbar shows the ones you actually use. You choose which appear, and in what order. IN EDITABLE FIELDS When you select text in a field you can type into, the result replaces your selection directly. Everywhere else it opens in a new tab, so nothing is overwritten by accident. HOW IT WORKS The extension is a front end for your HeyZenek account. Nothing leaves your browser until you pick a tool — selecting text alone sends nothing anywhere. There are no ads and no trackers. The AI tools need a paid HeyZenek subscription — plans start at $9 per month at heyzenek.com. Sign in once there and the extension uses that session: no separate login, no API keys to paste. SHORTCUTS There is a keyboard shortcut, Ctrl+Shift+K by default, and you can change it in the settings. Right-click also works. Both open the page you pick in the settings with your selection, and work even if you turn the toolbar off.
