I built a tool that makes any website multiplayer. Think google docs for the internet. Building with AI has led to more html & web-based artifacts than ever before. - Presentations - Product/technical documents - Prototypes - Guides & tutorials Anytime I'm sent one of these files, the process of asking questions or leaving feedback is painful. I have to read the doc, then jot down questions in apple notes, then slack someone, and keep going back and forth. So i was like "What if you can turn any web page into a google doc and make it multiplayer?" 10 minutes later, after using /goal and bypass permissions in Claude Code, Multi was born. V1 allows you to comment/reply on any URL. It also allows you to ask AI about anything you highlight & comment on. Use cases: - If a client wants to leave comments/feedback on a web page you build for them - If you have internal html docs that you want to go through feedback loops on - If I read an interesting article and leave color commentary for the team Possible future features: - Mentions + notifications: @ someone on a comment → he gets an email/Slack ping with a deep link. Without this, async review depends on people remembering to check. - Answer-or-escalate: when you ask a question, AI answers from the doc & is grounded on your internal knowledge base. If it's confident and tags it "AI-answered—confirm?"; if not, it pings the relevant person. - Browser extension: runs in your already-logged-in tab, so you can make live, authenticated internal apps multiplayer, not just public/static docs. This is the biggest unlock for your actual use case, and reuses ~all the overlay code. - Live cursors (see where the other person is pointing), typing indicators, emoji reactions on comments for low-effort agreement, and a daily digest ("3 open questions on docs you own"). - Linear integration: turn a comment thread into a Linear ticket. Plug into your software factory, so that comments go from tickets to PRs to merged features. Here’s a screenshot of what it looks like:
