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.

How is Cortex different from ChatGPT or a RAG chatbot?

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.

How is Cortex different from Notion AI or a knowledge base?

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.

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.

How does Cortex work?

Three steps: (1) Teach it with psychology interviews and voice capture on how you decide and communicate. (2) Build it as Cortex extracts identity, judgment, style, and memory into a living brain. (3) Deploy it so your clone answers in public chat, REST API, MCP for AI agents, voice replies, and Google Meet.

Does Cortex support MCP for AI agents?

Yes. Cortex exposes an MCP endpoint so external agents (Claude, Cursor, custom tools) can query a person's reasoning with tools like query_person, get_profile, get_expertise_on, and get_communication_style instead of using a generic system prompt.

Can Cortex join meetings?

Yes, on the Concierge tier. Cortex can join Google Meet as a bot, listen to the conversation, and speak back with the owner's judgment and voice. Useful when the person is double-booked or unavailable.

Is Cortex public by default?

No. New Cortex profiles are private by default. The owner opts in to a public clone URL when ready.

Is Cortex the same as makecortex.com?

Yes. Cortex is the product name. makecortex.com is the official website where you sign up, build your alternate intelligence, and manage your digital twin.

How much does Cortex cost?

Cortex offers Pro at $100/month (public chat, REST, MCP, and voice) and Concierge at $500/month (adds meeting agent, coding loop, unlimited queries, and human onboarding). Sign up at https://makecortex.com/signup.

What is Cortex?

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.

Alternate intelligence

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.

Build your alternate intelligence

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.
Build it — Cortex extracts beliefs, style, judgment calls, and tensions into a living intelligence brain, not a chatbot persona.
Deploy it — Your clone answers in public chat, REST API, MCP for agents, voice replies, and Google Meet, anywhere you cannot be.

Why Cortex is different

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

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.

API surfaces

When a profile is public, these endpoints expose the owner's clone:

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
