A single Socratic dialogue turn costs us real money — the AI that reads with you isn't free to run. A serious reader finishing one book a month costs us roughly a third of their subscription to serve. That leaves room to keep the lights on, keep adding books, and keep the product getting better without ads or selling your reading data.
The Voice tier costs more because voice synthesis costs more — we pass that cost through honestly rather than padding the base price.
If you use the product heavily and run into a daily limit, you'll see a clear message, not a surprise bill. No usage-based invoicing, no throttling surprises.
Subscribe through the web and you keep the same price on iOS, with the same account. Same library, same notebook, same commonplace book — just a different surface to read on.
