The install is literally one script tag.<br> What I shipped in 2 days:</p> <p>Backend server with Claude handling all the AI reasoning<br> Doc scraper that reads any URL and builds a knowledge base<br> Chat widget with markdown rendering, typing indicators, mobile support<br> Embeddable script that injects the whole widget into any website<br> Full demo page proving the one-line install works</p> <p>Here's the 90 second demo: <a href="https://www.loom.com/share/dbe84ce6dbe24b4cb968cae3172c4268" rel="noopener noreferrer">https://www.loom.com/share/dbe84ce6dbe24b4cb968cae3172c4268</a></p> <p>Biggest thing I've learned so far — ship the demo before you think you're ready. Two days ago this was just an idea in a spreadsheet. Today I have something I can put in front of real people.<br> Would love feedback from anyone who's built in this space or has opinions on pricing. And if you run a SaaS and support is a pain point — I'd genuinely love to set you up with a free trial.</p> ai claude showdev webdev
