"AI-powered" usually means "subscription-powered." $20/month here, $30/month there. Before you know it, you're spending more on AI tools than on coffee.

ONA.UNO works differently

No Subscription

ONA.UNO uses a pay-as-you-go model through OpenRouter. You add credit when you need it — $5 to start — and spend it over time. No monthly fee. No recurring charges. Skip a month? Pay nothing.

Real Numbers

Here's what actual usage looks like:

  • Initial setup (10,000 items): $3–4
  • Daily use (new items, chat, summaries): $2–5 per month
  • Light use: Under $1 per month

That first number is the big one — and it's a one-time cost. After your library is indexed, ongoing costs are pocket change.

Why So Cheap?

You're paying wholesale. ONA.UNO connects directly to AI providers (Google, Alibaba, xAI) through OpenRouter. No markup from us. No "AI credits" with mysterious exchange rates. Just actual compute costs.

A single chat message? Fraction of a cent. A full summary of your week? Less than a penny.

Complete Control

Set a spending limit on your API key. That's it. You literally cannot spend more than you allow. When credits run out, requests just stop — no surprise bills, ever.


The AI features that make ONA.UNO useful — semantic search, automatic summaries, chat with your knowledge — these aren't luxury features locked behind an expensive subscription. They're accessible for the price of a coffee per month.

Sometimes less.
