Not a chatbot that talks. An agent that does.

DeeZen lives on your computer and actually gets work done — it plans the job, browses the web, reads your documents, writes and runs code, creates media, and hands you the finished result. Privately, on your own machine. Free for the everyday — it only touches the cloud when a task genuinely needs it, on your key, not our meter.

No account needed for the free tier · your conversations never leave your device by default

Private by design Free for everyday tasks Speaks 50+ languages Honest ~$4/mo, not $20+
The difference

Give it a goal. It does the whole job.

Ask a chatbot a question and you get words. Ask DeeZen to do something and it works the task end-to-end — then hands you the result.

It plans, works, and delivers.

Tell DeeZen what you're trying to achieve — research a topic, build a spreadsheet, sort out a document, put together a project. It breaks the goal into steps, works through them (browsing real pages, reading files, running code), checks its own work, and gathers everything into a finished deliverable you can save, share, push to a repo, or deploy. You approve every big step.

Made with DeeZen

Use every machine you own.

Link 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.

Everything it can do

One app. The whole assistant.

Not a chat window bolted to a website — a real assistant that runs on your computer and does the work, start to finish.

Answers & writing, instantly

Rewrite an email, summarise a document, draft a letter or CV — answered on your machine in seconds, free.

Browses the real web

Deep research, not stale guesses — DeeZen navigates live pages, reads them, and cites what it finds.

Reads your documents

Drop in a PDF, Word doc, spreadsheet or a photo of a bill — DeeZen reads it and explains it in plain language.

Writes & runs code

Builds tools, crunches data, automates the tedious — and can run long jobs in the background while you get on with your day.

Drives your computer

With your approval, it can click, type and operate apps for you — gated by a safety switch you control.

Remembers you

It recalls your preferences, projects and past conversations — on your device, never our cloud. Ask it to forget anything, any time.

Works on your schedule

Set reminders and scheduled tasks — a morning briefing that runs itself, jobs that fire exactly when you want.

Connects your tools

One-tap connectors for your files, email, calendar and contacts — so it works with the things you already use.

Hands over the finished work

Save to your device, push to your code repo, or deploy to your own server. You approve every step.

Private by design

Your business stays on your machine.

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.

01 — Free & local

Everyday tasks run on your machine

Rewrites, summaries, letters, questions — handled by the AI on your device. Nothing uploaded. Always free.

02 — Your key, your call

Harder tasks use your own key

When a job genuinely needs a bigger model, it uses your provider account — billed by them, not us. We never touch your money.

03 — Honest about it

You always know which it is

DeeZen tells you when something leaves your device, and a cost dial puts a ceiling on spend. No surprises.

Honest pricing

About the price of a coffee. Not a $20 subscription.

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.

Everyday AI (local tier)Free
DeeZen subscriptionUS$4/mo
Cloud AI, typical use (your key)~$1/mo
Your all-in cost~$5/mo

A typical frontier AI subscription is ~$20+/mo. Cloud usage is metered by your provider on your key — DeeZen never marks it up.
