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

  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.

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
  • 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

  • Starter, $29/mo. Public clone chat, REST API, and MCP for your agents. The way in.
  • Individual, $100/mo. Everything in Starter with ten times the queries, plus spoken voice replies.
  • Concierge, $500/mo. Coding loop, owner agent, the largest monthly allowance, 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

FAQ

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.
What is Make Cortex?
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, and voice.
What is 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.
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 and MCP. 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.
Who is Cortex for?
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.
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 Starter at $29/month (Public clone chat, REST API, MCP for agents, About 800 full-quality answers a month, Then a faster model keeps answering until the 1st); Individual at $100/month (Public clone chat, REST API, MCP for agents, Voice replies, About 2,700 full-quality answers a month, Then a faster model keeps answering until the 1st); Concierge at $500/month (Public clone chat, REST API, MCP for agents, Voice replies, Coding agent loop, Owner agent (email + calendar), About 13,800 full-quality answers a month, Then a faster model keeps answering until the 1st, A human session to build the brain with you). Customers in India are billed in rupees. Pricing at https://makecortex.com/pricing.
