Chrome extension

Contextly

Contextly is a Chrome extension that helps you improve writing anywhere on the web. Select text on a page and a small overlay appears: choose a prompt (favorites first), preview the result, then apply it or copy it. Prompts cover spelling and grammar, tone rewrites, summaries, professional replies, and more.

How it works

When you run a prompt, only your selected text is sent to the Contextly backend for AI processing. You review the rewritten text before it replaces your selection or goes to your clipboard.

Step 1

Select text

Highlight text anywhere on the web. A small overlay appears so you can choose what to do next.

Step 2

Choose a prompt

Pick a prompt — favorites first. Options cover spelling and grammar, tone rewrites, summaries, professional replies, and more.

Step 3

Preview the result

Only your selected text is sent to the Contextly backend for AI processing. Review the rewrite before anything changes.

Step 4

Apply or copy

Apply the rewritten text to replace your selection, or copy it to your clipboard.

Sign in & manage prompts

The extension popup is for signing in and managing your personal prompts—create, edit, and mark favorites. Contextly does not browse, scrape, or change pages beyond your selected text and that overlay.

Built with privacy in mind

We only send selected text when you run a prompt, and you review the result before apply or copy. Read the full details on our privacy policy.
