LazyFirst IDE with integrated brain

The cockpit where you watch your agents work.

Lazy isn't just an assistant. It's the workshop where your agents code in a chain, right in front of you, in full confidence. You see, you understand, you stay in control.

LazyManager

Mission Control: the canvas where your agents move, orchestrated by LazyManager.

You describe a mission. For anything non-trivial, LazyManager first writes a short charter — the goal, the calls that need a decision (each with its own recommendation), what has to be signed off, and how to stop — so you're agreeing on the plan before any code gets touched. Any graph of three steps or more gets drawn out too, with an estimated cost and duration, for you to validate, adjust, or reject. Approvals stick even if you close Lazy and come back later, and a step only counts as done once its result is actually confirmed. Recurring work starts supervised and only runs unattended once you've approved enough runs to trust it.

Persistent memory

The brain that remembers your entire project.

Every decision, every correction, every idea stays remembered — captured live, available forever. Your AI never relearns your project, it already knows it.

Lower costs

Your agents catch themselves before they waste your budget.

While an agent is working, its LazyReasoningBlocks let it see for itself when it's slowing down or drifting off track — and correct course to get the task done right. If it can't fix itself, LazyManager automatically steps in and gets it back on track. Less wasted work, less budget spent redoing what went wrong.

Lower cost
Continuous improvement

Fewer runs that go sideways, less work to redo — your budget goes toward progress, not cleanup.

Built for you

No matter how you code, Lazy makes it better.

Whether you're shipping solo or leading a team, Lazy adapts to your workflow — not the other way around.

01

Solo developers

Stop re-explaining your project to every new AI chat. Your brain remembers your architecture, your decisions, your style. Code faster with an AI that actually knows your codebase.

02

Startup teams

Coming soon: give your whole team a shared brain, where decisions, patterns, and pitfalls are captured once and available to everyone. In the meantime, every developer already gets Lazy Solo's personal brain.

Power users

Delegate real work to agents you can watch. Plan, code, test, review — all transparent, all controllable. You're always the final say.

Frequently asked questions

Lazy is built around a persistent HTML brain. Unlike a plain chat history, it captures every decision, fix, and idea as rich HTML notes — searchable, linked, dated — and injects only the memories relevant to your current task into each conversation, instead of dumping your whole codebase into every prompt. That means far fewer tokens spent per conversation.

By default, everything stays on your machine. Your brain, your memories, your code — all local. The free plan never sends your data to our servers. Pro plan offers managed AI but your brain remains yours.

The free plan doesn't even require an API key if you already have a Claude subscription: connect the Claude Code CLI (or the Codex CLI) and Lazy uses it directly, no key, no extra cost. You can also bring your own Anthropic API key, or run a fully local model (Ollama, LM Studio) with everything staying on your machine. Lazy adds zero markup on any of these — you already own the access, we just plug into it.

Not yet, but soon: Lazy Teams will give your whole team a shared brain, with every developer contributing to the same knowledge graph. Decisions, patterns, and pitfalls will be captured once and available to everyone. In the meantime, every developer can already use Lazy solo, with their own personal brain.

Lazy is currently available on Windows. macOS and Linux builds are coming soon. The IDE is built native — not Electron — so it's feather-light and fast.

Instead of sending your entire codebase to the AI (which is expensive and noisy), Lazy's brain identifies and injects only the memories relevant to your current task. This means sharper answers, lower costs, and conversations that stay focused.

Built for people who'd rather create than remember.
