Put an AI support agent on your website with one script tag. It answers from the content your site already publishes, so when you update a page, the answers update too. Set the name, color, greeting, and a few suggested questions. When the agent can't help, the visitor leaves an email and the question. You get the email. They get a confirmation.

Hi Product Hunt! I'm Tony, founder of Cosmic.
We built this for ourselves first. Leo, the support agent on cosmicjs.com, answers questions from our docs and knowledge base articles, and when those don't cover something, it falls back to the live site. When Leo can't help, the visitor leaves their email and question, and it lands in our support inbox with a confirmation sent back to them.
Once Leo was working, we turned it into something any Cosmic customer can add to their own site. It answers from the content your site already publishes, so when you update a page, the answers update too. Install it with one script tag, set the name, color, and greeting, and choose which domains it runs on.
You can try Leo right now, no signup needed: https://www.cosmicjs.com/ai/supp...
What would you put it on first: your help center, your pricing and product pages, or your docs?
"when you update a page, the answers update too" is the line that makes me want to know the actual lag. if an editor fixes a wrong price at 2pm, is Leo answering with the new number by 2:01, or is there some index/embedding rebuild step that takes a few minutes, during which the agent confidently gives the old number with no indication it might be stale? that gap between "content changed" and "agent knows content changed" seems like the one place this could quietly go wrong
Answering from the content the site already publishes is the right call — no second knowledge base to keep in sync. Does it handle bilingual sites (e.g. Arabic + English pages) and answer in the visitor's language? That's a big deal for GCC businesses. Congrats!
The one script setup sounds pretty straightforward. It could be really handy for smaller teams that don't want to spend much time setting up a separate support system.
