The problem with one more subscription
Subscriptions assume steady, predictable use. AI usage is rarely like that. Some weeks you lean on it constantly, then a fortnight goes by and you barely open it. With a flat monthly fee you pay the same either way, so the quiet stretches are pure waste.
And it stacks. A plan for this model, another for that one, and suddenly AI is a standing cost you have stopped noticing.
How pay as you go works here
Unium has no subscription. Sign-up is free. You top up a prepaid balance, and credits come out of it only when you actually run something that costs money - a paid model, web search, an image. Where free models are available, they do not touch the balance at all.
So a quiet month costs almost nothing, and a heavy month costs what that month was worth. Nothing in between is wasted. Credits stay valid for up to a year, so you are not rushing to burn them before a reset.
You can see what you are spending
Because spending is tied to use, you can actually watch it. You pick which model handles each message, so a pricier model is a deliberate choice rather than a thing you forget you are paying for. If you share a wallet, the same applies to the group balance - it only moves when someone uses it.
Topping up
Credit packs are on the pricing page. Web top-ups go through Paddle and iOS through Apple, and every purchase has a 14-day money-back guarantee, set out on the refunds page. No auto-renewing plan sits in the background - you top up when you want more.
