Built for productivity enthusiasts and knowledge workers.
Cortex Buddy is a personal knowledge workspace where your notes, documents, and thinking models feed into AI that produces real work. Not just storage. Not just retrieval. Execution. Plus, it has chat.
Join the betaNot just
You’ve spent months setting up your productivity system. The folders are right. The tags are consistent. The daily notes flow into weekly reviews. Everything is organized beautifully.
And then you need to actually produce something — a plan, a draft, an analysis — and you open a separate AI tool that knows nothing about any of it.
Your main knowledge domain is one Area — all your notes, projects, documents, and agents centralized in one place. Use projects to separate the different efforts within it and tags to make everything findable.
Got multiple domains? Personal development, a side business, a creative practice? Each gets its own Area. Clean separation without duplicate effort.
Mention what you need in any note, and work starts. Results arrive in your inbox. The best pieces go in your vault. Your system doesn’t just store knowledge — it acts on it.
This isn’t chat. This is an AI workspace that compounds. Plus, it has chat.
Features
Cortex Buddy builds a living profile of how you process information, what kind of output you value, and how you prefer things structured. You don’t configure it. You just use it, and it pays attention.
Notes are compiled into structured knowledge articles by a background agent. Instant recall at 50 notes or 5,000 notes, without ballooning costs. Your knowledge base gets smarter as it grows.
Promote any document to a Core Doc. A dedicated agent watches for conflicts between new notes and these documents. Your most important docs stay current without you babysitting them.
Organize your life into Areas and Projects within them. Each has its own context, agents, and thinking model. Your fitness notes don’t dilute your business context.
Your data lives on your device and export is always yours. Download your entire workspace as markdown anytime — no lock-in, no hostage situation.
One assistant with many capabilities, plus custom ones you shape. Ask for next steps, a cleaner workspace, or the blind spots you’re missing. Schedule any capability on your cadence.
We know you have opinions about your tools. Markdown notes. Your data on your device. No vendor lock-in — export everything as markdown anytime. This isn’t a walled garden. It’s a workshop.
No feature gates. Every plan includes the full platform — you pay for the AI, never for unlocks. Bring your own AI — an API key, a Claude Code subscription, or local models — and the platform starts at $0, covering only your own usage. Prefer we supply everything? That starts at $9/month against a weekly meter that resets Monday.
Four modes — Cruise, Drive, Overdrive, Full Throttle — are your cost dial, so you decide how far each dollar stretches versus how much firepower each task gets.
