Your knowledge. In every AI you use.
ContextNest Desktop installs your local context engine — the layer that keeps Cursor, Claude, and Antigravity working from what you actually know. Download once. Runs quietly in the background. No cloud, no subscription, no configuration.
ContextNest Desktop
Your knowledge vault, always on. Open it to see what your AI knows, keep it current, and manage your connections — then close it. It keeps running.
Your AI starts from zero.
Every single time.
Every session starts with you doing the AI's job for it. Here's the brief again. Here's the context. Here's what you decided last Tuesday. The model processes it, gives you an answer — and forgets everything the moment you close the tab. Tomorrow you'll do it again.
It is not an AI problem. It is a context problem. And it compounds every day you leave it unsolved.
One context. Every conversation.
ContextNest sits on your machine and builds a persistent memory layer every AI you use draws from. Ask Claude about a project — it already knows the brief. Switch to Cursor mid-task — same context, zero re-briefing. Come back tomorrow — nothing is gone.
All your tools. One shared brain. Running locally, privately, always on.
3× more efficient. Every answer.
Your AI pulls only what's relevant — not your whole filing cabinet. Sharper answers, fewer wasted messages. Backed by peer-reviewed research.
Private by architecture, not policy.
Your files never leave your machine. Not encrypted in transit, not stored on our servers — never sent at all. There's nothing to breach.
Compounds over time.
Every document you add makes the next answer sharper. Unlike a chat session, nothing resets. The longer you use it, the more it knows.
ContextNest is what your AI knows. PromptOwl is what it can do — and who controls it.
Agents that act on your context. Skills that automate your workflows. MCP tools that connect to your stack. Build the complete AI work system — not just a smarter chat window.
And when your organization needs role-based access, approval workflows, cryptographic audit trails, and enterprise-grade infrastructure — that's PromptOwl too.
When your team is ready, deploy Community Edition in minutes — a free, self-hosted server your whole team connects to. One governed knowledge vault. Every teammate's AI draws from the same approved, versioned knowledge. Bring a PromptOwl account — that's the only requirement.
Your context is waiting.
Choose the path that fits your workflow — a local memory engine for yourself, or a governed server for your team.
