AI agents by Max Sergeev

AI agents that run on one brain.

Does your agent know your business?↓
01Hands and brain

Agents are the hands. Kortex is the brain.

Same mainstream AI models everyone uses. The hands are the same everywhere. What changes is what they know.

A Kortex is one brain for a business: it sponges in every call, email, chat, doc, ticket and commit. Every agent reads it before it works.

An agent alone

Happy to help! Could you tell me what you ordered last time, and where it should go?

No evidence. It just met you.
The same agent on a Kortex

Done: same 40 units, matte finish, delivered Thursday morning, because the Friday drop got refused twice. Invoice goes to the new billing address from your last email.

Same model. Same prompt. Different brain.The alone one stays polite. The Kortex one cites the receipts.
02Why agents fail

Why do AI agents fail?

Not for lack of brains. For lack of memory.

An agent without context is a temp on day one, every day. It asks the same questions, makes the same mistakes, and what it learns is gone by Friday. The work gets done. The learning evaporates.

Left: smart, polite, new forever.Right: every task that teaches the brain is done twice over.
03The trust dial

Who presses send?

You do, until you don't want to.

Every task an agent does comes with one choice: Draft, Ask or Automate. Everything starts in Draft. As it proves itself, a task moves to Ask, then Automate. Trust grows one task at a time.

04The agents

Which AI agent do you need?

Six I build and run. Each one reads the same brain.

Pick the hands that match the work. Plug them into one Kortex and they share everything they learn.

The call copilot predicted the result of a client's data query (1,769 records, with the breakdown) before the client ran it, because it already had the context.
Client Loom videos get transcribed and matched to the pull requests that close them.
An agent writes a client's PPC and SEO reports every morning and their operations review every week.

Kortex for business is a concept I'm building. The agents above already run in production for clients, and my own operation runs on a Kortex.

06Questions

Questions people actually ask.

01What is an AI agent, in plain words?
Software that does a job instead of just answering a question. It reads, decides and acts: merges the code, answers the customer, takes the call, writes the report. A pair of hands that never clocks out.
02How does an AI agent know my business?
From a Kortex: one brain that sponges in your calls, email, WhatsApp, Slack, CRM, docs, tickets and code. Every agent reads it before it works and writes back what it learned. Without it, the agent is a temp on day one, every day.
03Does the agent send things without me?
Only if you say so. Every task has a dial: Draft (it writes, you send), Ask (it checks with you first) or Automate (it just does it). Everything starts in Draft and moves up as it earns your trust.
04Can an AI agent answer WhatsApp for my business?
Yes. An AI employee I built answers customers on WhatsApp for a client: 3,247 messages handled so far. It answers, books and follows up, on the channel your customers already use.
05Which AI agent should I start with?
The one sitting on data you already have. Lots of calls: the call copilot. A busy WhatsApp: the AI employee. A backlog of tickets: the AI engineer. The 2-minute audit shows where your business leaks the most.
06Is Kortex a product I can buy?
No. Kortex is an idea: a brain every company builds its own way, like a website. Kortex for business is a concept I'm building now. The agents on this page already run in production for clients, and my own operation runs on a Kortex.
