What Curio costs
Usage-based, priced from our real token cost, and shown before you spend a cent. No seats, no monthly floor, no per-domain fee. Here's exactly what a unit is and what it costs.
The unit is a conversation
One visitor, one chat thread, is one conversation. Every question and follow-up inside it belongs to that same conversation. You're billed for the model tokens each answer actually uses, and nothing for the questions Hugo never gets asked.
During your free trial a whole conversation — every follow-up included — is $0.
What one conversation costs
These are the live running average from our own usage, not a list price. Your actual cost moves with how long a conversation runs. The same number drives the counter on the homepage.

How the meter works
We pay Anthropic for the model and Voyage for embeddings. You pay that model cost times your plan's multiple, drawn from a prepaid balance. Here are the raw per-million-token rates we're billed, so you can check the arithmetic yourself:
| Model | Input / M tokens | Output / M tokens |
|---|---|---|
| Claude Haiku 4.5 | $1.00 | $5.00 |
| Claude Sonnet 4.6 | $3.00 | $15.00 |
Multiply the tokens an answer uses by these rates, then by 5.2× (Standard) or 8.5× (Pro). That is the whole meter. When your prepaid balance reaches $0, Hugo pauses politely and tells the visitor — it never runs up an overage or a surprise invoice.
What the multiple pays for
The gap between our raw token cost and your price isn't margin alone. It covers the embeddings and the daily re-crawl that keep answers current; the free trial nobody pays for; the credit we hand back automatically when we have downtime; the help desk and live human handoff; and the hosting, with enough left over to keep building. We would rather show you the multiple than bury it in a "contact sales" quote.

Per-conversation figures are the live running average from our own usage and vary with conversation length. Token rates are set by the model providers and change when they do; your exact usage and prepaid balance are always in your portal. The 30-day trial needs no credit card.
