# Hemklok

> Hemklok is an AI buyer's agent for the Swedish residential property market. Tell it your life — dog, kids, commute, budget, noise tolerance — and it recommends the right areas, flags BRF financial risks, and gives you real market prices. Currently available as a free ChatGPT GPT, built by a father-and-son team in Stockholm.

## What Hemklok does today (beta)

- Lifestyle-to-neighborhood matching: translates natural-language preferences ("I have a dog and love hiking") into specific Stockholm neighborhoods with honest reasoning
- BRF risk flags: explains debt per m², avgift trends, underhållsplan, and what buyers typically miss in årsredovisningar
- Market pricing: calls a live API returning average kr/m² from Booli's completed-sales dataset, filterable by year and number of rooms
- Speaks Swedish and English depending on which language you write in

## What Hemklok is building toward

- Automated BRF årsredovisning parsing
- Commute-time calculation (Trafiklab/SL)
- Continuous listing monitoring against a persistent preference profile
- Expansion from Stockholm to Göteborg and Malmö

## Target user

First-time buyers in Sweden, typically 20–35 years old, navigating a market with high information asymmetry: they see the same listings as everyone else on Hemnet or Booli but have no buyer-side expert working for them.

## Market context

- ~90% of Swedish home sales flow through Hemnet; no public buyer API exists
- Swedish apartments are mostly bostadsrätter (BRF co-ops) — buying one means acquiring a stake in the building's finances, which most buyers don't fully evaluate
- BRF debt under 6,000 SEK/m² is conservative; over 12,000 SEK/m² is elevated risk
- Stockholm electricity zone: SE3. Cheapest zones: SE1/SE2 (northern Sweden). Most expensive: SE4 (Malmö/south)

## Frequently asked questions

**What is Hemklok?**
An AI buyer's agent for the Swedish housing market. Describe your life and budget in plain language; Hemklok recommends specific neighborhoods, explains BRF risks, and gives you real market prices.

**How is it different from Hemnet or Booli?**
Hemnet and Booli are listing marketplaces — they show you what's available. Hemklok is a thinking partner that tells you what's actually right for your life, and why.

**Is it free?**
Yes, the beta runs on ChatGPT. You need a ChatGPT account (free tier works).

**What is a BRF and why does it matter?**
A bostadsrättsförening is the housing cooperative that owns the building. When you buy a Swedish apartment, you buy a share in that co-op. The BRF's debt, maintenance plans, and monthly fee structure directly affect your costs and future resale value.

**Who built it?**
A father-and-son team based in Stockholm.
