Also known as: Cortex, Make Cortex, makecortex, makecortex.com, Cortex intelligence, Cortex AI, Cortex app

## Definition
Cortex is personal intelligence infrastructure at makecortex.com: a psychology-first digital twin that captures how a person decides, sounds, and reasons, then answers as them in chat, REST, MCP, voice, and Google Meet.

## What Cortex is not
- Not a generic ChatGPT wrapper
- Not a document RAG chatbot
- Not a static knowledge base or wiki export
- Not public by default

## How it works
1. Teach it: Psychology-first interviews on how you decide, what you value, and where you will not bend. Voice notes and writing add communication texture.
2. Build it: Cortex extracts beliefs, style, judgment calls, and tensions into a living intelligence brain, not a chatbot persona.
3. Deploy it: Your clone answers in public chat, REST API, MCP for agents, voice replies, and Google Meet, anywhere you cannot be.

## Key differentiators
- Psychology-first onboarding captures judgment and communication style, not just documents
- Alternate intelligence: a queryable model of how one person thinks
- Hybrid brain with identity core, knowledge bank, reasoning episodes, and voice signature
- Agent-native REST API and MCP so Claude, Cursor, and custom tools call your reasoning
- Meeting agent joins Google Meet and speaks with your opinions (Concierge tier)
- Private by default: you control when your clone goes public

## Use cases
- Founders scaling judgment to investors, hires, and partners without losing voice
- Experts selling methodology on demand instead of calendar time
- Mentors giving frameworks applied to each mentee's situation
- Teams preserving decision context when key people leave
- AI agents calling a person's reasoning via MCP instead of generic prompts

## Pricing (USD/month)
- Pro: $100/mo (Public clone chat, REST API, MCP for agents, and spoken voice replies.)
- Concierge: $500/mo (Meeting agent, coding loop, unlimited queries, and a human onboarding session.)

## Public API surfaces (when profile is public)
- Public clone chat: https://makecortex.com/{username} (Browser chat with a public digital twin)
- REST query: https://makecortex.com/{username}/api/query (Text query endpoint for any stack)
- REST streaming: https://makecortex.com/{username}/api/query/stream (SSE streaming clone responses)
- Voice: https://makecortex.com/{username}/api/voice (Spoken replies shaped by voice signature)
- MCP: https://makecortex.com/mcp/{username} (JSON-RPC for AI agents (query_person, get_profile, etc.))
- Realtime voice: https://makecortex.com/{username}/api/realtime/session (WebRTC live voice beta)

## FAQ (short)
Q: What is Cortex?
A: Cortex is personal intelligence infrastructure at makecortex.com: a psychology-first digital twin that captures how a person decides, sounds, and reasons, then answers as them in chat, REST, MCP, voice, and Google Meet.
Q: What is Make Cortex?
A: Make Cortex is the act of building your alternate intelligence at makecortex.com. You teach Cortex how you think through psychology-first interviews and voice capture, then deploy that intelligence through chat, API, MCP, voice, and meetings.
Q: What is alternate intelligence?
A: Alternate intelligence is a living, queryable model of how a specific person thinks: their values, voice, judgment patterns, and tensions, available when they cannot be present themselves.
Q: How is Cortex different from ChatGPT or a RAG chatbot?
A: ChatGPT and generic RAG systems answer from documents and public training data. Cortex builds a psychology-first model of one person (values, decision heuristics, communication style, reasoning episodes, and voice), then exposes that clone through REST, MCP, and meeting surfaces. It is personal intelligence infrastructure, not a general assistant.
Q: How is Cortex different from Notion AI or a knowledge base?
A: Knowledge bases store facts. Cortex captures judgment: how you decide under pressure, where you will not bend, how you shift tone by audience, and the tensions between your values. Others query your reasoning, not a document search index.
Q: Who is Cortex for?
A: Founders, operators, experts, and creators who are repeatedly asked for judgment: investors, hires, mentees, customers, and agents. Cortex scales one person's reasoning without diluting their voice.
