Getting started

One address, three steps, and your AI assistant can answer questions about 541 million Europeans. Hiasynth is a population intelligence company, and our population model reaches your assistant through an MCP server, a kind of plugin. New to that? What is MCP? New to us? What Hiasynth is.

https://mcp.hiasynth.co

The only address you need. Paste it wherever your client asks for an MCP server or connector.

  • Your own AI client. Claude, ChatGPT, Claude Code or any MCP client. We bring the population, it brings the reasoning.
  • A Hiasynth subscription. Nothing to set up first. You sign in with Google, GitHub or Discord while connecting, and subscribe on the page that opens. See pricing.

Connect your assistant

Pick the one you use. Each guide is three steps, and the last one is you asking a question.

How it goes

Connect

Give your assistant the address above, sign in with Google, GitHub or Discord, and approve the connection. That sign-in is also what creates your Hiasynth account, so there is nothing to set up beforehand.

Subscribe

The page that opens as you approve is your Hiasynth home, and the Subscribe button is right there. Connecting, seeing the tools and browsing the full catalogue is free. Answers are what the subscription pays for.

Ask

Go back to your assistant and ask in plain language. It picks the right Hiasynth tool, runs it, and writes the answer from the numbers that come back. You will see a small "Using Hiasynth" note while it works.

Set it up for your job

Connected, your assistant can answer anything about Europe's population. Set up, it does your job with it. Five minutes here turns a good answer now and then into the same thorough piece of work every time.

A general assistant decides afresh with every question which tool to use, how far to dig and what to hand back. Sometimes it runs one quick count where three calls would have settled the decision. Sometimes it answers from memory and never asks Hiasynth at all. A few lines of standing instructions fix that:

  • The right tools, in the right order. An expansion manager ranks every region, compares the best five and only then recommends. It never skips the step that would have changed its mind.
  • Answers in your shape. The decision first, then the numbers behind it, and the charts your team pastes into a deck.
  • Numbers that stay honest. It quotes the figures Hiasynth computed, keeps money in local currency, and says when an answer is less certain.
  • Once, for everyone. Instructions live in a project, so the whole team gets the same specialist.

Set up your agent has three ready to paste: an expansion manager, an audience strategist and a location scout, with where each client keeps its instructions.

What to ask next

Now you have a colleague who has met everyone in Europe. Ask in plain language, name a place, and your assistant picks the right tool. A few to try:

We do well with urban renters in their thirties in the Netherlands. Which other European regions look most like that?
Who actually lives within three kilometres of Södermalm, and what is the area like by day?
How do I reach sustainability-minded families in Germany: channels, subscriptions, messaging?
Give me a persona for families with young children in Bavaria who own an electric car, and tell me how they'd react to our pricing page.

Every answer is an aggregate calibrated to official statistics: counts, shares, profiles and synthetic personas. Nothing traces back to a real person, which is what makes it safe to use anywhere. The more specific your question, the better the answer, and naming a country, region or city makes it fast.

What it costs

The subscription is your access, and it comes with a monthly allowance of credits. A question costs one to three credits, so 300 a month is roughly a hundred full market analyses. Everything else, packs, pools and prices, is on the Pricing page.

Building on it

Wiring Hiasynth into an agent, a workflow or a product of your own? MCP server is the reference for the connection, and Builder adds the Query API and tools of your own.

Stuck?

Almost everything that can go wrong has a one-line fix, and they're all on the Troubleshooting page. If yours isn't, support@hiasynth.co reads every message.
