What the price actually is

$8.30/month. Tiers are bounded by a monthly quota of 'advanced' queries against frontier models, with cheaper models unmetered, so the quota matters more than the fee. Annual billing is advertised lower.

The usage this is priced against

150 substantive queries a month against a frontier model — the quota the paid tier exists to sell — each carrying roughly 4,000 tokens of page or document context and returning 600.

Someone using it half as much sees double the multiple. The assumption is the argument — if you disagree with it, the number below is not about you. Change it in the calculator.

The cost math, in full

Rates come from a dated rate card of representative published API prices, not from the vendor. Nobody outside these companies knows what they actually pay; volume discounts and in-house serving both push real costs below these figures, which makes every multiple here a floor rather than a ceiling.

Why this verdict, not the number

This is the clearest architecture in the directory: there is no model here, only routing. The extension is genuinely well made — summarising the page you are on, without a copy-paste round trip, is a real convenience — and offering several vendors' models behind one subscription has value for someone who does not want several subscriptions. But the thing being sold sits entirely between the user and someone else's API, which is what the word describes. Note that the same convenience argument defends it: for a non-technical user, an extension that works everywhere is worth more than a cheaper key they would never configure.

What the price buys besides tokens

• UX craft
• Distribution
• Orchestration

One subscription across several vendors' models, in a sidebar on every page, with sensible routing between cheap and expensive models. The routing is the only engineering that is hard to copy, and it is invisible to the person paying.

What you lose if you leave

A model in the sidebar of every page you visit, and not having to choose which vendor to subscribe to. For someone who would otherwise pay for two assistants, the bundle may genuinely be cheaper.

The honest cheaper path

Any first-party assistant subscription, or an open browser extension such as Sider's free tier or a self-hosted equivalent pointed at your own API key. The key costs what the tokens cost.
