How it works
Four steps from "I use AI"
to "I architect AI workflows."
Cortex rewires how you think. The Studio runs entire workflows visually. Bring your own API key — your data never leaves your control.
Train your prompting brain
Start with Cortex — 5 free + 7 paid micro-courses built on 8 cognitive-science pillars. You don't watch videos. You externalize your thinking, pick between A/B paths, spot the structural keys in good prompts, and earn certificates.
Connect your API key (once)
Paste your Anthropic or OpenAI key into Settings. Stored only in this browser's localStorage. Forwarded per-request, never logged, never persisted. Audit every call in your browser's network tab.
Build workflows in the Studio
Open the Studio. Drag node-type pills from the top bar — Goal · Role · Context · Instruction · Chain-of-Thought · Output Format · Self-Critique · Agent Loop. Connect them with typed edges (sequential · parallel · conditional · loop · feedback). Or load one of 12 pre-built templates.
Run and export
Hit Run. Watch nodes execute in order, edges animate as data flows, output streams into your terminal nodes. Copy the final result, or export the whole workflow as JSON · YAML · Mermaid · LangGraph Python · Executable JS · or a full Next.js project zip.
Privacy by design
Your prompts. Your keys. Your control.
Keys live in your browser
Never persisted on our servers. Cleared when you log out.
Every call is auditable
Inspect headers, payloads, responses in your network tab.
Server-side proxy, no logs
Your key is forwarded per-request, never persisted. We log only run analytics — no keys, no prompt bodies.
