zy.ai
Free to start. Pro when quality is weekly. Ultra when research is.
No card to try. Five guest messages, then a real Free tier. Frontier labs are a $15 decision, not a surprise checkout.

Honest upgrade signals: Free vs Pro · when free is enough · one subscription, many models.
Is Free actually usable?
Yes. Free is free models with a daily cap, not a watermarked demo of one paid lab. Guest try is five messages so you can feel the product first.
What do I get at $15 that I do not get free?
Frontier models (Claude, GPT, Gemini, Grok as offered), higher limits, and API / Developer Console. Same chat surface.
Who should buy Ultra?
People who use Voice or research agents most weeks, or who hit Pro limits. Not a status upgrade.
Start on Free. Upgrade when the work demands it.
