The first IDE with a brain.
Lazy is the AI code editor that remembers everything — decisions, fixes, ideas, architecture. A persistent HTML brain that grows with you, plus a team of agents you can actually watch work. Stop re-explaining your project to every new chat.

Memories captured and searchable
A brain built in HTML — because your knowledge deserves more than plain text.
Most AI assistants forget everything after the conversation ends. Lazy's brain is different — it's built as rich HTML pages with full personality: colors, structure, links, tags, temporal validity. Every memory is a living document you can navigate, search, and explore.
- Rich HTML notes — not flat text dumps
- Clustered by topic, linked by meaning
- Temporal validity — knows what's still true
- Searchable, navigable, yours forever
Your AI remembers everything.
Every decision, fix, and idea is captured automatically and brought back the moment it matters. No more re-explaining your project. No more lost context. Your brain grows smarter with every session — and it's all stored locally, on your machine.
Explore the BrainAgents working in plain sight.
Hand off real work to a team of agents. Watch them plan, code, and review in real time. Step in anytime — you are always in control. No black boxes, no magic — just transparent, accountable work.

Sharper answers. Dramatically less waste.
Lazy's brain doesn't just remember — it compresses. Instead of sending your entire codebase to the AI, Lazy injects only the relevant memories. The result: conversations that cost a fraction of what they should, with answers that are sharper because the context is cleaner.
What makes Lazy different from every other AI editor.
Cursor, Windsurf, and Zed are great AI editors. But none of them remember. Lazy is the only IDE with a persistent HTML brain that grows with you — making every conversation smarter, not just longer.

Early builders are already coding smarter with Lazy.
"Lazy is the first tool where my AI actually remembers what we decided last week. The brain changes everything — I stopped re-explaining my architecture in every chat."
Alex Chen
Staff Engineer, Fintech Startup
"The HTML brain is genius. I can see my decisions as living documents with tags, links, and context. It's like having a wiki that writes itself while I code."
Sarah Kim
Tech Lead, AI Infrastructure
"Token savings are real. My API costs dropped dramatically because Lazy injects only the relevant memories instead of dumping my whole codebase into the prompt."
