Where AI helps in a Swiss apartment search
| Step | What AI does | Where |
|---|---|---|
| Searching | You describe the flat in your own words | Comparis inside ChatGPT, since 22 September 2026 |
| Seeing every portal | Not AI: one feed of Homegate, ImmoScout24, Flatfox and about 800 cooperative websites | aptari |
| Documents | Reads your salary certificate, ID and debt extract once at upload, for the document check | aptari |
| Cover letter | Writes a letter for the flat from your saved dossier, in four languages | aptari, Pro and Ultra |
| Applying | Prepares your message with a private link to your dossier. You send it | aptari, Apply with Aptari |
| Applying for you | The Apply Agent applies to partner listings that fit, in the background | aptari, Ultra. Starts as soon as partner agencies list; none have yet |
| Deciding | Nothing. A person at the agency chooses the tenant |
Coming on aptari, not available yet: an assistant that helps you search and set up your saved searches in conversation.
What AI does in an apartment search, point by point
A lot of apartment sites throw the word "AI" around. Here is what AI genuinely helps with when you are hunting for a flat in Switzerland, and what to ignore.
What AI does well
1. Not AI, but it belongs here: your fit, by fixed rules.
Most people waste time applying to flats they were never going to land · the income did not fit or the listing asked for a non-smoker. aptari gives every listing a Match Score from 0 to 100. The score is built from your income against the rent, how complete your dossier is, your checked documents and the listing's smoking and pet rules. You see the number and the facts behind it, so you spend your energy on the apartments you fit.
2. It checks your documents.
When you upload your salary slip, ID and debt extract, aptari checks them so your dossier looks complete and credible to the agency. It is a check, not a judgement · the agency still decides.
3. It writes your cover letter.
Your Tenant Passport stores your details once. On Pro and Ultra, and during the 14-day free trial, aptari then writes a clean cover letter in German, French, Italian or English, matched to the language of the listing. You read it and tweak it before it goes out.
4. Later: it can apply for you (Ultra plan, partner listings only, none on aptari yet).
On the Ultra plan, the Apply Agent watches new partner listings and applies for you in the background to the ones you fit, up to a daily limit you choose.
What AI does not do
- "AI predicts which landlord will say yes." No one can predict that. Agencies pick a tenant for personal and legal reasons that are not in your data.
- "AI invents a brand-new story for every listing." Be careful: AI that makes things up can get your salary, address or references wrong. Your cover letter should be built from your real saved details, which is how aptari does it.
- "AI bids above the asking rent for you." Avoid it.
- "AI scans landlords' social media." That is a privacy problem, not a feature.
How aptari keeps it safe
- The Match Score is built only from your own information. Same details in, same score out · no guessing.
- The AI never decides who gets the apartment. The agency always chooses the tenant.
- Your documents are handled safely. Your data is stored in the EU (Frankfurt); some processing is done by providers in the USA, see the privacy policy.
- You can always open any Match Score and see why you got it.
aptari brings all of this together: Match Score, AI cover letters and the Apply Agent for partner listings, all on top of one saved Tenant Passport. Start your search on aptari and let it do the heavy lifting.
