AI tools are remarkably powerful. But ask Claude to prep you for a meeting, and it has no idea who you're meeting, what you discussed last time, or what you promised to follow up on. The problem isn't the model — it's the context.
Déjà bridges that gap. It connects to your email, calendar, meetings, and messages, then builds a local knowledge base — a structured map of your people, projects, commitments, and conversations — that any AI tool can read.
No data leaves your machine. There's no cloud sync, no account to create, no new tab to keep open. Déjà runs quietly on your Mac, keeping your knowledge base current as signals arrive. The AI tools you already use — Claude, Cursor, ChatGPT, Copilot — simply become smarter because they finally know your world.

Everything lives on your machine. Nothing is uploaded, nothing is shared, nothing leaves your disk. Export it, back it up, or delete it anytime.
Context is what makes AI useful — not bigger models or fancier prompts. Give any model the right context and it becomes genuinely helpful.
Connect your accounts, let Déjà catch up on your history, and forget about it. It works in the background, keeping your knowledge base current — forever.
