AES-256 Encrypted

Your conversations
become an API.

Talk about what you know. Cortex extracts, encrypts, and organizes it into a knowledge API that any AI tool can pull from.

Start for Free See How It Works

Your knowledge, extracted, encrypted, and ready for any AI tool.

Chat to Knowledge

Talk naturally about your stack, rules, and processes. AI extracts and organizes the facts for you.

Universal API

One endpoint that returns your knowledge as markdown, JSON, or plain text. Works with every AI model.

Encrypted

AES-256 encryption at rest. Store API keys, client details, internal processes. Even we can't read your data.

See It in Action

Talk. Extract. Pull via API.

You chat about what you know. Cortex extracts facts, organizes them by topic, and serves them through your personal API.

Got it. I extracted 3 facts:

Payment provider: Stripe

Refund policy: 30 days

API on Cloudflare Workers

Also our database is Supabase with row level security enabled

Added to your Brain. Encrypted and available via API.

Database: Supabase + RLS

How It Works

Three steps. No setup. Just talk.

From conversation to API in seconds.

Chat Naturally

Tell Cortex about your stack, rules, processes, clients. Talk like you'd talk to a teammate.

AI Extracts Facts

Cortex reads your messages and pulls out structured facts. It organizes them into topics automatically.

Pull via API

Any AI tool calls your API. Claude Code, Cursor, ChatGPT, your own apps — if it reads text, it works.

Two-Way API

A knowledge base that grows itself.

Most wikis die because nobody updates them. Cortex grows automatically. AI tools don't just read your knowledge — they write back what they learn.

Read: Pull Context

GET your knowledge as CLAUDE.md, system prompts, or JSON.

Write: Push Discoveries

AI tools push new facts back. Your brain grows while you work.

Always Encrypted

Both reads and writes go through AES-256. Data protected at rest.

READ ↓# Pull knowledge into any project
curl -H "Authorization: Bearer bp_sk_..." \

  > CLAUDE.md

# Ask your brain a question
curl -H "Authorization: Bearer bp_sk_..." \
  "https://api.usecortex.net/brain/ask?q=refund+policy"

WRITE ↑# AI tools push knowledge back
curl -X POST -H "Authorization: Bearer bp_sk_..." \

The Problem

Your team's knowledge is scattered. Cortex fixes that.

Knowledge lives in Slack threads, Notion pages nobody reads, and people's heads. When someone leaves, it leaves with them. Cortex captures it all in one encrypted, searchable place.

No more lost knowledge when people leave

Onboard new hires in minutes, not weeks

Every AI tool gets the same accurate context

Developers

AI coding tools get your rules

Your coding standards, architecture decisions, and project context — automatically available to Claude Code, Cursor, and Copilot.

Support Teams

Chatbots that know your product

Feed your real policies and procedures to any support bot. It answers with facts — not guesses.

Sales Teams

Full context before every call

Store client history, pricing, and objections. Pull everything before meetings — close more deals.

Individuals

Your personal brain backup

Everything you know — encrypted, organized, and accessible from any AI tool. Your knowledge, always with you.

HR & Onboarding

New hires get answers instantly

Your company playbook — processes, tools, culture — available instantly. No more week-long onboarding.

Knowledge Management

A wiki that updates itself

No more outdated docs. Talk about changes as they happen — Cortex keeps your knowledge base fresh.

Security

Your knowledge, locked down.

Store anything — API keys, client details, credentials, internal processes. Your knowledge is encrypted before it touches our database. Even we can't read it.
