DeeZen answers your everyday questions right on the machine you already own — free, private, instant. It only reaches for expensive cloud AI when a question genuinely needs it, and it tells you exactly what that costs.
Free everyday tier, forever. $4/month if you want the cloud too — your own key, metered by you, usually about a dollar a month. Not $20+ a month for everyone.
The big AI subscriptions charge everyone $20+ whether they use it or not. DeeZen flips that: the everyday questions are free on your computer, and the cloud is billed per-question by your own provider key — visible to the cent, in the app, the whole time.
One app. It quietly decides, question by question, whether the answer should come from your computer or from the cloud — and it only spends money when it has to.
Rewrites, summaries, letters, CV help, the daily stuff. A small local model handles these on your own machine — instant, private, and it never costs a cent. This tier stays free, forever.
Deep analysis, high-stakes answers, vision, media creation. When a question genuinely needs a bigger brain, DeeZen escalates to the cloud using your own provider key — billed per question by your provider, kept tiny by DeeZen's efficiency engine.
A simple dial: Saver, Balanced, or Best. It's a cost ceiling, never a quality floor — DeeZen will always answer on the local tier if it can do the question justice, whatever the dial says.
No competitor can show you this receipt — for them, it would expose the margin. For DeeZen, it's the whole point.
DeeZen is built by ZenCognitics, an Australian company. We make money from the $4 product and nothing else. We don't mark up the cloud — that's billed straight by your own provider, and we'd rather it stayed about a dollar a month.
Windows first. Mac when the signing cert clears. Linux after that. The download is one self-contained file — no Python, no setup, no account needed to start.
