The Chatbase alternative that never goes dark at your limit.
Sunbeam reads your site and answers your visitors from your own content — with a link to the page it answered from, and an honest “I don't know” when the answer isn't there. And when you reach your plan's limit, it keeps answering instead of showing your visitors an error.
- Keeps answering past your limit
- Cites the page it answered from
- 3-day trial, card on file

The difference shows up on your busiest day.
A metered chatbot goes quiet exactly when traffic spikes past your plan. Here is how the two behave, on the things a visitor actually notices.
The visitor waiting on your site sees this until credits reset or you upgrade.
The widget keeps answering. Extra conversations bill at your plan's published flat rate — your site never goes dark.
Once message credits run out, the agent shows visitors “This AI Agent is currently unavailable,” until credits reset or you upgrade.
One flat monthly conversation allowance, then a single published per-conversation overage rate. No surprises.
Per-message credits — a reply can cost 1–6 credits depending on the model — that reset on the 1st with no rollover.
An answer layer: one script tag, answering your visitors from your own pages. No inbox, tickets, or live chat to run.
An AI agent platform for customer experience and support.

It says “I don't know” instead of making things up.
A chatbot on your own website is a promise to your visitors. Whether it declines cleanly when it doesn't know is the moment they decide if it's trustworthy — so it's the line we hold hardest.
Grounded in your pages — honest when it isn't sure
Every answer is grounded in your own content. When the answer isn't on your site, Sunbeam says so and hands off to the fallback you choose — it doesn't fill the gap with a guess.
Every answer cites its source
Each reply links back to the exact page it came from, so your visitor — and you — can check it in one click. A confidently wrong answer about your prices is worse than no bot at all.
