About ChatGenius: Instagram Caption & Hashtag AI

Write better Instagram and Facebook posts in seconds. ChatGenius is an AI content assistant that generates captions, hashtags, posting times, and fresh post ideas in your own brand voice, right from your browser toolbar. Open the popup, describe what your post is about, pick a tone, and get: • Captions: scroll-stopping Instagram and Facebook captions written to match your brand, with a built-in character counter and one-click regenerate. • Hashtags: a relevant mix of high, medium, and niche hashtags based on your caption and your business. • Best time to post: suggestions for when your audience is most active. • Post ideas: fresh, on-brand content concepts for when you run out of inspiration. Why it is different: most caption generators produce generic text. ChatGenius pulls from your saved business profile, so captions actually sound like your brand instead of a template. Who it is for: creators, social media managers, small businesses, and agencies who post on Instagram and Facebook and want to save time without sounding robotic. How to use it: 1. Install the extension. 2. Click the icon and sign in with your SumGeniusAI account. 3. Start generating. Note: the AI Assistant requires a ChatGenius Creator plan or higher.
