DeeZen answers questions, writes for you, speaks your language, creates media and gets real work done — privately, on your own machine. Free for the everyday. It only touches the cloud when a task genuinely needs it, and then it uses your key, not our meter.
No account needed for the free tier · your conversations never leave your device by default
Not a chat window bolted to a website — a real assistant that runs on your computer and does the work.
Talk or type in 50+ languages — Spanish, Vietnamese, Arabic, Mandarin, Italian and more — and get the answer back in your language. Real voice too: speak and hear it reply, on your device. Powered by your own translation server, not a silent hop to the cloud.

Generate media with a free draft lane on your own hardware, or studio-quality results when you want them — on prepaid credits that never expire. Everything on this page was made by DeeZen itself.
Create somethingLink your computers over your own network into one private compute mesh. DeeZen spreads heavy jobs — big computations, media renders, long tasks — across your machines, so the strong box does the lifting while you work on any of them. Your own distributed system, no cloud required.
Build your mesh

Rewrite an email, summarise a document, draft a letter or CV — answered on your machine in seconds, free.
Drop in a PDF, Word doc, spreadsheet or a photo of a bill — DeeZen reads it and explains it in plain language.
Save to your device, push to your code repo, or deploy to your own server. You approve every step.
Set reminders and scheduled tasks — a morning briefing that runs itself, jobs that fire when you want.
Most AI sends everything you type to someone else's server. DeeZen is built the other way around — it runs on your computer, so your conversations, documents and keys stay with you by default.
Rewrites, summaries, letters, questions — handled by the AI on your device. Nothing uploaded. Always free.
When a job genuinely needs a bigger model, it uses your provider account — billed by them, not us. We never touch your money.
DeeZen tells you when something leaves your device, and a cost dial puts a ceiling on spend. No surprises.
The free tier genuinely works, forever. The paid product is the full assistant — router, efficiency stack, every feature — for a few dollars a month, and your cloud usage is billed at cost by your own provider.
A typical frontier AI subscription is ~$20+/mo. Cloud usage is metered by your provider on your key — DeeZen never marks it up.
One download, a minute to install, and the everyday AI is free from the first run — no account, no card, nothing uploaded.
