Know the fair rent before you sign the lease.
Helvetia Rent collects commercial listings across Swiss markets, cleans them into one comparable shape, and estimates fair monthly rent with a regression or LLM model. One dashboard over a modular Python framework you can extend with new sources and models.
Rent distribution
Three modules, cleanly separated.
Scrape
A registry of source-specific scrapers. Drop a class into the scrapers package, decorate it, and it shows up across the CLI and this dashboard - no other file changes.
Process
Messy CHF and m² strings, German/French/Italian category labels, and missing cantons are normalized into one typed listing with a derived CHF/m²/year rate.
Predict
Pluggable estimators score fair rent: a transparent regression model with no dependencies, or a GLM / OpenAI-compatible LLM with market comparables and a rationale.
