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 when it does, 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.
Rewrite an email, summarise a document, draft a letter or CV, explain anything — answered on your machine in seconds, free.
FreeTalk or type in 50+ languages — Spanish, Vietnamese, Arabic, Mandarin, Italian and more — and get the answer back in your language. Powered by your own translation server, not a silent hop to the cloud.
50+ languagesSpeak to it and hear it reply — voice input and spoken answers run locally. No audio uploaded anywhere unless you say so.
VoiceGenerate media with a free draft lane on your own hardware, or studio-quality results when you want them — on prepaid credits that never expire.



Drop in a PDF, Word doc, spreadsheet or photo of a bill — DeeZen reads it, extracts what matters and explains it in plain language.
DocumentsDeeZen doesn't just answer — it delivers. Save the finished work straight to your device, push it to your code repo, or deploy it to your own server. You approve every step; it does the legwork.
Save · Push · DeployLink 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 heavy lifting while you work on any of them. Your own distributed system, no cloud required.
Local mesh · distributed workloadsMost 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. Here's the deal, in plain terms.
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 — you're 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, no silent data-hoovering.
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+/month. DeeZen is the price below — and we show you the maths.
vs ~$20+/mo for a frontier subscription. 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.
