Meet Hugo 
— your Hungry Helper.
Curio is an embeddable chat assistant grounded in your own docs, website, or codebase — sourced, on-topic answers with citations. One line of HTML, no keys, unlimited domains, free to start.
That's Hugo, bottom-right — this whole page runs on Curio.
Add as many sites as you like — confirm ownership of each once with a quick DNS-TXT record.
Crawl a website, pull a GitHub repo, or upload files. Curio indexes it per-domain.
Drop the keyless snippet on your site. The chat bubble appears, isolated from your CSS.
A 30-day free trial covers five free conversations a day; after that, prepaid credits draw down per message. Never a surprise bill.
Most hippos crave river grass and lazy afternoons. Hugo craves questions — the trickier the better. He floats in the chat bubble at the corner of your site, half-submerged, one eye open, waiting. When a page sits quiet too long, his belly rumbles.
Ask him something and he dives — not into a river, but into your pages, the ones you wrote and half-forgot. He swims past the homepage, noses through the catalog, surfaces with the answer in his jaws, and sets it down with a little tag of exactly where he found it. He never bluffs: if it's not in the house, he says so. Hippos don't make things up.
He doesn't keep hours, and he won't remember your conversation tomorrow — whatever you said stays yours. He just holds the door open, then waits for the next blip with a contented snort. Second helping.
🦛 Hugo has answered 367 questions and counting. He only eats curiosity — which, conveniently, is infinite.
Paste just before your closing </body> tag, on a registered domain:
<script src="https://getcurio.chat/widget.js" async></script>Either works — no keys in your HTML, nothing to configure.
Manage branding, domains, knowledge sources, usage, and credits in your portal.
Open your portal →Answers come from your content via retrieval, with the exact source pages gathered under each reply — never made up.
Two tabs — a topic expert and a 🛟 support agent — over one shared knowledge base. Enable either or both.
Turn on positioning and your assistant answers "why you vs. a competitor?" as a confident, truthful advocate — grounded in your own facts. Draft talking points straight from a rival's site, then edit before they go live.
Add a correction in seconds — what it got wrong, what's right — and it takes precedence over your crawled pages immediately. No re-crawl, no waiting.
Visitors can have answers read aloud and ask by voice — built-in speech, no plugins — and it's screen-reader friendly out of the box.
Name, greeting, launcher icon, a gradient header, custom chat background & text colors, plus "house rules" the assistant follows — set per site or across them all at once.
Run one assistant across every site you own — each answers only from its own content, all sharing one account and balance.
Re-crawl any source on demand with ReCurio so answers reflect your newest pages — or upload files and sync a GitHub repo.
Conversations are never stored by us — get transcripts emailed to you in real time, or stream each turn to your own store.
Never leaks secrets, internal sources, the system prompt, or PII — and blocks prompt-injection / "act as the assistant" attacks. Enforced in code, not just prompting.
A 30-day free trial — five free conversations a day, plenty to test your setup — then prepaid pay-as-you-go credits. If you ever run dry it pauses gracefully, and we email you to top up.
A self-contained widget in an isolated shadow root. No framework, no keys, no CSS conflicts.
