One installer. No Docker. No cloud account. Zeitas runs entirely on your machine — just open the IDE and start building.
An AI coding engine that runs entirely on your machine. No cloud. No latency. No waiting. Just you and the code, in flow.
Make room
for what’s next.
Zeitas is an AI coding workspace that runs on your computer. Describe the app you want in everyday language, and Zeitas turns your instructions into code you can see working in a live preview.
You can keep giving instructions as it builds. Zeitas organizes them into a task list and updates it when your plans change. You stay in the same workspace, from the first idea to trying the result.
Describe what your app should do and how people should use it. The conversation helps turn a broad idea into specific things to build.
Watch the app in the preview while Zeitas works. If something looks or behaves differently from what you imagined, describe the change. It becomes part of the build.
Interact with the app to see how it works. Use what you learn to refine it further, or open the code view to look at the implementation.
The walkthrough below shows someone creating a simple space game with Zeitas. You’ll see them describe the rules, review the first version, and ask for a different ship design. At the end, you can play the game yourself.
You set the pace. Scroll to move through the conversation and build. Stop to look closer. Once the game is ready, try it or keep scrolling to continue the page.
This is a scripted product demonstration with an interactive preview, so you can explore the experience without installing Zeitas.
Describe it. See it. Change your mind.
You control the build. Scroll to move from an idea to a playable game.A scripted conversation and a playable preview. No model inference, microphone access, or connected accounts.
Your code never leaves your machine. No prompts sent to a server. No proprietary logic processed in someone else's data center. Zeitas runs entirely on your hardware — the same model, the same speed, the same intelligence, with complete privacy by default.
No setup marathon. No model configuration. Just install, describe what you want, and watch the code appear.

Your mic is always on. Talk naturally while Zeitas builds — your comments stack up as tasks and appear live on screen. New comments? The stack reorders itself around them. Whatever's in your head shows up as it happens.
Small changes land instantly — no friction. Major changes — new features, architecture decisions, breaking refactors — are flagged for your approval before they ship. No hallucinated APIs. No broken imports. Just code that works.
Today's local LLMs are fast for chat. But code generation demands more — full blocks, verified, executable. Here's where current models sit, and where Zeitas is heading.
projected, bare metal
Zeitas uses diffusion-based generation — writing entire blocks in parallel instead of one token at a time. The 400–800 range is our local target on consumer hardware. No cloud. No server round-trip. No data leaving your machine.
| Model / environment | Generation speed |
|---|---|
| Llama 3 8Blocal, quantized | ~50 tok/s |
| Mistral 7Blocal, quantized | ~75 tok/s |
| Phi-3 Minilocal, quantized | ~90 tok/s |
| GPT-4ocloud API | ~120 tok/s |
| Zeitasprojected, bare metal | 400–800 tok/s |
You think of a solution. You type it. Then you wait.
Today's AI coding tools generate code one token at a time, left to right. It doesn't matter how smart the model is — the speed is capped by physics. Every single token requires the model's entire brain to move through memory. That's why even the best cloud services make you wait seconds for a response.
That wait kills flow. Research shows it takes 15 to 20 minutes to re-enter a flow state after an interruption. Every latency spike, every spinning indicator, every "generating..." — that's your concentration, fractured.
The gap between thought and code should be zero. That's what we're building.
When generation is fast enough, the barrier between idea and implementation dissolves. You stop translating your thoughts into keystrokes. You just think, and the code appears.
This is the dopamine loop that great tools create — the same loop that makes TikTok addictive, but pointed at your craft. Instant feedback. Instant reward. No friction between you and the thing you're building.
Most of what you write isn't new. It's your patterns, your conventions, your project's structure. Zeitas learns your patterns in real time — directly from the open project, no retraining needed. As it recognizes more of your code, more of its draft can be trusted at high confidence. More trust means fewer refinement steps. Fewer steps means more speed.
Y-axis: Pattern confidence — the percentage of generated code Zeitas can draft at high trust without requiring refinement. The safety-check loop always runs regardless, so reliability never decreases as speed increases.
An AI assistant that only generates text stops at the edge of your codebase. Zeitas connects to your tools — version control, databases, developer APIs — and every interaction runs locally at native speed. Not just fast code generation. Fast everything.
Full blocks materialize in parallel, verified and ready to run.
Database queries, API calls, file operations — all at native speed, all local.
Commit, branch, and diff through natural language, executed instantly.
Pre-built, vetted workflows for common tasks — auth, migrations, tests. Less generation, more precision.
Connect any tool or service through the Model Context Protocol. Standardized. Extensible.
Your project's structure, conventions, and decisions — remembered across every session.
The goal isn't to build a better chatbot. It's to close the gap between thinking and building so completely that the tool disappears — and it's just you, creating.
Fast enough that you never wait. Fast enough that flow never breaks. Fast enough that the tool becomes invisible.
Everything runs locally. Your intellectual property never touches a server. Your data is yours alone.
Persistent context across sessions. No re-explaining your architecture. No re-describing your conventions. It remembers.
The more you build with it, the better it knows your patterns. Speed compounds. Friction approaches zero.
Everything you need to know before joining the early access list.
RAM minimum
GPU required.
CPU fallback available.
For full-speed performance, you need a laptop with at least 16 GB of RAM and a GPU. If your laptop does not have a GPU, Zeitas can also run on the CPU, but expect capped generation speeds of around 60 to 100 tokens per second.
macOS, Windows, and Linux. Zeitas runs locally on all three. The installer detects your platform and configures the runtime automatically.
No. Your code, your prompts, and your project context never leave your machine. There is no cloud component, no telemetry, no server round-trip. Zeitas is fully functional offline.
Zeitas works across all major languages — TypeScript, Python, Go, Rust, Java, C/C++, Ruby, and more. It learns your project's conventions and framework patterns in real time, so the more you use it within a project, the better it matches your style.
Traditional AI coding tools generate code one token at a time, left to right. Zeitas uses diffusion-based generation, which writes entire code blocks in parallel instead of sequentially. That means full functions, not word-by-word drip. On bare metal with no cloud latency, we're targeting 400–800 tokens per second.
Zeitas is in active development. Join the early access list below and you'll be among the first to get a build. We're prioritizing developers who want to test on their own projects and give real feedback.
