AI balance: topping up and what it's spent on

The builder's AI assistant (chat, photo recognition) is a paid feature on top of the Pro subscription — it has its own prepaid balance in kroner, separate from the subscription payment. Top it up on the "AI balance" page (linked from the profile dropdown menu): there are a few preset amounts or you can enter your own (from 20 kr), paid by regular card via Stripe, credited instantly. It's charged based on actual usage — the real cost of the tokens the AI model processed plus a small site markup, not a flat "per attempt" price. You're charged for any response the AI actually returns — including when a photo turns out not to contain a recipe, or the assistant couldn't extract a single usable ingredient: the AI still did real work and spent real tokens on your request. Only genuine technical failures are free — when no response comes back at all (network error, service unavailable). A voice message is first transcribed to text for free, and from there it's billed the same as a regular typed message — speaking instead of typing doesn't add extra cost. A single voice recording is capped at three minutes. Translating a recipe into other languages (via the button or through the assistant), on the other hand, never touches the AI balance at all — that's a separate free mechanism. To protect it from abuse, voice messages and translations are both rate-limited to a few dozen per hour — normal builder use never comes close to that limit. The "AI balance" page shows a full transaction history (top-ups and charges, each with a description of what was paid for), with pagination and PDF/Excel export.
