Is WG-Lotse really free?

Yes. The core scoring, red flag detection, district map, and message templates are free forever with no listing cap. Paid tiers only unlock the AI features (about-me translation).

Which sites does WG-Lotse work on?

WG-Gesucht.de and Kleinanzeigen.de (the WG section).

What data does WG-Lotse collect?

Nothing for the free tier - all scoring runs in your browser. For AI features, only the specific text being analysed is sent to the backend, and only when you trigger it. WG-Lotse never sells data, tracks browsing, or builds profiles.

Does WG-Lotse write my application message for me?

It drafts a German application message based on your about-me text and the listing details. You review and edit before sending. It's a starting point, not a fire-and-forget bot.

Can I use WG-Lotse from outside Germany?

Yes, as long as the listings are on WG-Gesucht or Kleinanzeigen.

WG-Lotse Chrome extension in action on a WG listing

Everything you need. Nothing you don't.

Six features built around how apartment hunting in Germany actually works.

WG-Lotse overlay showing an 86% strong match score with green checks for budget, location and WiFi — Score overview

WG-Lotse score breakdown showing individual criteria like budget, location, timing and compatibility — Score breakdown

Free

Instant fit scoring

Open a listing and your score appears immediately - 0 to 100, based on your budget, location, timing, room size, house rules, and lifestyle preferences. Calculated in milliseconds, entirely in your browser. Nothing leaves your machine.

Free

Know in seconds if it's worth your time

Women-only. Students preferred. No English speakers. Anmeldung required from day one. These dealbreakers are buried in German descriptions - sometimes politely, sometimes between the lines. WG-Lotse reads them for you instantly. And when the mismatch is softer - timing slightly off, budget borderline - you still get to draft a message and try your luck.

Hard blocker: listing is for women only — Hard stop - skip it

Soft blocker: timing off, but draft message anyway option available — Soft mismatch - try anyway

Clickable district map of Hamburg with selected neighbourhoods highlighted in orange

Free

Stop guessing which districts to care about

Hamburg alone has over 100 districts. When you're new to the city, they're just names. I spent weeks applying to listings in areas I later realised were an hour's commute away. WG-Lotse shows you a clickable map - pick the neighbourhoods you'd actually want to live in, and filter everything else before you even open a listing.

AI feature

About-me translation & smart drafting

Write your intro once in any language - the extension translates it into natural German and weaves it into every message alongside your preferences, move-in date, and budget.

A note from the builder

I built this because I've been there.

Two months. That's how long finding a WG in Hamburg took me. Not because there were no listings - there were hundreds. But every listing meant opening it, decoding the German word by word, and realising at the end it didn't fit anyway. Women-only. Students preferred. Anmeldung required from day one - and I'd just arrived. The platforms let you filter by price and room size. Everything else - house rules, hidden requirements, which districts even make sense - you had to figure out yourself.

I built WG-Lotse because I needed it. Open a listing, the score appears instantly. Red flags are surfaced before you've read a single sentence. If it looks right, one click drafts your application in German. Navigating the sea of WG listings to find your safe harbour - a bit easier.
