The SmartBar in one minute
You drop a document and CIRO recognises what it is. You ask a question and the Hausmaister answers with what is in your account.
What landlords use the SmartBar for
The SmartBar is the bar at the bottom right of every page in CIRO. In every plan the Hausmaister answers questions about how CIRO works and opens the right page for you. From Smart, CIRO reads your documents and the Hausmaister knows your account: properties, tenants, vacant units, tickets, maintenance, open payments, tasks and your financial overview. Ask which rent is missing in October and it answers with the name and amount, without you laying your bank statement next to your tenant list.Updated: 10/27/2026
The heating invoice becomes a booking
You drop whatever arrives on the SmartBar: the heating engineer's invoice, the service charge statement, a lease or the Excel list from the previous manager. CIRO recognises the type of document, reads the data and shows it to you for review.
The invoice becomes a booking, the service charge statement starts your utility bill statement, the lease becomes a tenancy and the Excel list your portfolio. The SmartBar takes PDF, JPG and PNG, and XLSX, XLS and CSV for spreadsheets. Reading documents is available from Smart.
Answers with names, amounts and addresses
Which rent is missing in October? Which unit becomes vacant next? The Hausmaister answers with names, amounts and addresses from your account and links the page where you carry on. On request it creates a property or a tenancy.
It also answers general questions about renting. Landlords and a tenancy lawyer have checked its knowledge. Questions about CIRO are answered in every plan, questions about your data from Smart.
When the Hausmaister has to pass
If the Hausmaister has no reliable answer, it creates a support case on your request and attaches the conversation. Our team can see what you already asked and gets back to you personally.
You can reach us by phone every day from 10 a.m. to 6 p.m. at 089 24 88 31 22.
Ask the Hausmaister a question
The Hausmaister knows about renting and, from Smart, about your units. Try it: ask about the deposit, a missing rent or what a building brings you each month.
The live demo uses prepared answers and a sample account. In CIRO, from Smart, the Hausmaister answers with the data in your account. Its answers on tenancy law are no substitute for legal advice.

Which documents can I drop on the SmartBar?
The SmartBar accepts PDF, JPG and PNG, and XLSX, XLS and CSV for spreadsheets. CIRO recognises the type of document on its own, reads the data and shows it to you for review. CIRO only creates something once you confirm the preview. Reading documents is available from Smart, including during the trial.
| You drop | CIRO turns it into |
|---|---|
| an invoice, for example from the heating engineer | a booking |
| your owners' association service charge statement | the start of your utility bill statement |
| a lease | a tenancy |
| an Excel list, for example from the previous manager | your portfolio with buildings, units, tenants and contracts; the Hausmaister asks about unclear columns |
What can the Hausmaister do in which plan?
In every plan the Hausmaister explains how something works in CIRO and opens the right page for you. Everything for which it needs your own data is available from Smart.
| Feature | Basic | Smart and Pro |
|---|---|---|
| Search in the SmartBar and questions about using CIRO | yes | yes |
| Questions about your data, such as open rents, vacant units or upcoming repairs | no | yes |
| Create a property or tenancy on request | no | yes |
| Read documents and Excel lists | no | yes |
If the Hausmaister has no reliable answer, it creates a support case on request and attaches the conversation so far.
How reliable are answers on tenancy law?
The Hausmaister answers general questions about letting with reference to the law. In the live demo on this page, every answer on tenancy law names the provision: § 551 BGB for the deposit, § 556 (3) BGB for the utility statement deadline, § 558 BGB for rent increases. Landlords and a tenancy lawyer have reviewed its knowledge. Its answers do not replace legal advice on an individual case. If you are in a dispute with a tenant, take the case to a lawyer.
What happens to my data in the AI?
The AI behind the Hausmaister is Google's Gemini, provided by Google Ireland Limited in Dublin. CIRO has concluded a data processing agreement with Google, as Art. 28 GDPR requires, and your input is not used to train the language models. Data may also be transferred to Google LLC in the USA; the EU-US Data Privacy Framework applies to such transfers. The Hausmaister only accesses the data in your own account. In your settings, one switch turns the AI off completely, including reply suggestions and document recognition. The details are in the privacy policy.
Frequently asked questions
Both. Hausmaister is the AI in CIRO and answers around the clock, for example questions about how something in CIRO works. If it can't solve something, it creates a support request for our team that includes the conversation so far. You can reach our support by phone daily, 10 a.m. to 6 p.m. at 089 24 88 31 22.
The spelling is deliberate. A Hausmeister is a building caretaker in German, and the "ai" in the name stands for the AI doing the work here. The caretaker still looks after the stairwell, the heating and the front-door lock. Hausmaister handles the desk work: it answers questions about CIRO and your apartments, creates properties and tenancies, and passes requests on to our support team.
Yes. One switch in the settings turns off the AI completely, including Hausmaister, reply suggestions and document recognition. Individual AI features can't be switched off separately. The switch also applies to anyone who co-manages your account. CIRO then works with fixed rules only, and you enter by hand whatever the AI used to read for you.
On every plan, Hausmaister explains how things work in CIRO and opens the right page for you. On Smart and up, it also answers questions about your own data, such as which rents are outstanding, which apartments are vacant or which repairs are coming up, and creates a property or a tenancy when you ask. Anything it can't answer, it passes on to our team as a support request.
Hausmaister only accesses the data in your own account. The AI behind it runs on servers in the EU, and your data is not used to train AI models. You can switch it off at any time with the AI switch in the settings.
Search in the SmartBar and questions about how CIRO works are available on every plan. Hausmaister answers questions about your own data, such as outstanding rents or vacant apartments, on Smart and up (€30 / month). You can try it during the 60-day free trial on Smart.
