An assistant that knows your business.
Hire Castellar to build chatbots and AI assistants for your website or product—grounded answers, streaming UI, and a clear path to human handoff.
Overview
Castellar builds chatbots and AI assistants that answer real questions from your site, docs, or product—not generic chat widgets. We scope what the assistant should (and shouldn’t) say, wire streaming UI, and leave you with something you can operate.
Who it’s for
- Teams that answer the same questions by email or WhatsApp every week
- Founders who want a demo-quality assistant on their marketing site
- Product teams adding in-app help without standing up a full ML squad
What you walk away with
- 01
A scoped assistant with clear topics, tone, and refusal boundaries
- 02
Streaming chat UI that matches your brand—not a generic embed
- 03
Handoff to email or your team when the bot shouldn’t guess

Questions about chatbots & ai
FAQIs this just ChatGPT on my site?
No. We design the assistant around your offer, content, and limits—so it stays on-brand and doesn’t invent prices or policies. The public Castellar demo is an example of that approach.
Can it use our docs or FAQ?
Yes. Many builds start from a fixed knowledge set or FAQ; larger projects can add retrieval from docs when the corpus warrants it.
What about cost and abuse?
We ship with rate limits and sensible message caps. Model and hosting costs are part of the proposal so you’re not surprised after launch.
