Johnny Bui's profile on Product Hunt

About

I've built software for 13 years, most of it as a technical lead and software architect. Now I build my own products under ThinkSwarm, from Da Nang, Vietnam: LopHoc.app (tuition management for Vietnamese teachers) and Embent — an AI agent that answers a website's visitors only from the site's own pages, with citations, and admits when it doesn't know. I build with AI agents daily and I'm open about it. Ask me the hard questions.

Embent launches tomorrow — an AI agent that answers from your website, or admits it can't

I'm Johnny, solo founder. Embent is an embeddable AI agent you point at your website or docs: it answers visitor questions only from what you actually published, cites the page under every answer, and the part I care most about says "I don't know" instead of improvising, then logs that question so you know exactly which page to write next.

The homepage is the demo: paste your URL at embent.com, no signup, and a real bot built from your own site is answering about a minute later.

We're live on Product Hunt tomorrow (Aug 20). Before that, I'd genuinely love this crowd's stress test: paste your site, ask it your hardest questions, and tell me where it breaks. That "where it breaks" list is literally the feature it's what the Unanswered inbox is for.

Ask me anything about how Embent grounds its answers

I'm Johnny, the founder. Embent answers only from pages it actually crawled from your site, cites the page under each answer, and refuses when your site doesn't cover the question every refusal lands in an "Unanswered" inbox so you know which page to write next. Launching tomorrow if you're curious how the crawling, retrieval, or the "I don't know" behavior works under the hood, ask away. Blunt questions welcome.

Embent - Paste your URL, get an AI agent that answers from your site

Embent is an AI agent for your website. It answers visitors only from your own pages — with citations under every answer — captures leads, says "I don't know" instead of inventing, and logs every question it couldn't answer so you know exactly which page to write next. Try it without signing up: paste your URL on embent.com and a preview bot built from your own site is answering in about a minute.
