Cleverreply

CleverReply is a Chrome extension that drafts AI-generated comments and replies on LinkedIn, X (Twitter), and Instagram using Google Gemini. You provide your own Gemini API key — it is stored only in your browser and never sent to any CleverReply server.
When you open a comment or reply field on a supported site, CleverReply injects a small button next to the composer. Click it and the extension reads the surrounding post text (and optionally post images), sends that context to Gemini, and inserts the generated reply directly into the field for you to review and post yourself.
Tone is adjusted per platform: professional on LinkedIn, short and natural on X, and casual on Instagram. You can further customize output with your own instructions, set a maximum character length, and optionally allow the extension to include post images as visual context for Gemini. A built-in usage counter lets you cap how many AI generations the extension performs. The extension is not affiliated with LinkedIn, X Corp., Meta, or Google.
