Free plan
Free AI Chatbot for Your Website
Train a chatbot on your own pages and documents, put it on a live website with one snippet, and pay nothing until it has earned its keep. No card, no trial clock.
What the free plan is for
Enough to launch one real chatbot and decide with evidence, not a demo video.
One chatbot on a live site
Create it, copy the snippet, paste it before the closing body tag. The widget is live on your real pages, not a sandbox.
Trained on real content
Upload a document, add website pages, or paste a YouTube link. Answers come from those sources and say so when a question is outside them.
Answer quality you can judge
Ask the twenty questions your visitors actually ask and read what comes back. If the answers hold on your content, paying is a safe decision.
A hosted page to share
Every chatbot gets its own page and link, so you can test it and show it to a colleague before it touches your website.
Where free stops
The limits are deliberate and published. Here is what you run into first.
A daily message cap
The free plan answers a fixed number of messages per day. A quiet site never notices; a busy one hits the cap, which is the moment to upgrade.
Fewer, smaller sources
Fewer documents per chatbot and a lower file size limit. Enough to prove the idea on one product or one course, not to index a whole help center.
A Cortexvia badge
The free widget carries a small Cortexvia mark. Paid plans remove it; nothing else about the widget changes.
No custom domain
The hosted chatbot page lives on a Cortexvia address on the free plan. Paid plans can put it on your own domain.
The same snippet as every paid plan
Two CDN files, a container, and a mount call with your chatbot key. Upgrading changes nothing here.

- Works on WordPress, Shopify, Wix, Squarespace, Webflow, React, Next.js, and plain HTML
- mode chatbot is the floating launcher; mode chat is an inline panel
- The loader is deferred, so it does not block your page from rendering

Start with one page and one document
Launch on the free plan, read the answers, and only pay once the widget is doing real work.
Free to launch, free to keep small. Create the chatbot, paste the snippet, and let real visitors ask the first questions.
