The listing record

What Superhuman Go: AI Assistant does

Superhuman Go for Chrome is a proactive AI assistant that works alongside you across the web—understanding what you’re working on and stepping in with the right support at the right time. It brings AI directly into your workflow, so you can stay focused without switching tools or losing momentum. With the Superhuman Go extension, AI assistance is built into the way you work: • Works everywhere you work – Runs in every tab and web-based tool, ready when you are, without getting in the way. • Knows what you’re working on – Understands what’s on your screen, so you skip the copy-paste-and-explain step other AI tools require—no prompts or uploads needed. • Proactive, on your terms – Spots concrete ways to help—polishing a reply, prepping you for a meeting, summarizing a long thread—then surfaces them in the moment. Go suggests; you decide.
