About HeyZenek
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.
You need a free HeyZenek account. Sign in once at heyzenek.com and the extension uses that
session — no separate login, no API keys to paste.
SHORTCUTS
There is a keyboard shortcut, Ctrl+Shift+E by default, and you can change it in the settings.
Right-click also works.
