The challenge

Homeowners' associations and property management companies drown in the same questions: how much do I owe, when will the hot water be back, whose car is in my spot, who do I call about a leak. Managers answer them by phone at all hours, while the answers already sit in their accounting systems.

A dedicated resident app is not the fix — nobody installs one more app. And plugging AI into personal data is risky: a chatbot that can see the whole building can leak a neighbour's phone number or debt to anyone who asks.

The solution

Domovyk meets residents where they already are. They write to a Telegram bot — or ask Claude directly — in plain language, and the assistant answers from live building data: charges and debts, announcements, meters, parking, vehicles, service contacts and the association's knowledge base. Residents can even submit meter readings in a chat message.

Under the hood is an MCP server that gives the AI a set of precise, permission-aware tools instead of raw database access. A resident is identified by their phone number — no passwords, no sign-up — and one person can own property in several buildings. Managers get a back office to run organizations, staff roles, privacy rules, announcements and meter readings, with data imported from the accounting platform they already use.

Security is designed in from the first line: every request passes through a single access-policy layer, organizations are fully isolated, an assistant never gets more rights than the person behind it, and neighbours' personal data is removed before it ever reaches the model.

Key capabilities

  • 01

    Answers from real data

    Debts, announcements, meters, parking, vehicles and contacts come straight from the building's records — the model never guesses.

  • 02

    Zero-install for residents

    Telegram or Claude, signed in by phone number. No app, no password, no onboarding.

  • 03

    Privacy by architecture

    Neighbours' names and phones are redacted in the data layer, not by prompt instructions — the AI simply never receives them.

  • 04

    Multi-tenant by design

    One platform for many HOAs and management companies: isolated organizations, staff roles scoped down to a single building.

  • 05

    Full audit trail

    Every access records who looked at what, when and through which channel — visible to the organization.

  • 06

    Back office for managers

    Announcements, meter readings, contacts, knowledge base, privacy rules and imports from the existing accounting platform.

The result

Domovyk is live at domovyk.co.ua and answers real residents in Telegram. The platform is backed by more than 200 automated tests.

For a management company, connecting a new building is a data import, not a project: residents just ask in the chat instead of calling the office, and every data access stays on an audit log the organization can review.
