About Linca
Linca is an AI receptionist for companies and business owners. When they cannot take a call, Linca does not only answer it, it handles it. It answers the caller’s question, sorts the call and qualifies the inquiry. You can follow the call live in the app, and within 3 seconds after the call you get a notification with the summary.
For iPhone and Android · First 5 handled calls free
Real estate agents, lawyers, financial advisers, clinics, car services, massage therapists, tradespeople, business owners and other people who do the work and also answer the phone use Linca. They stay professionally available to their clients and call them back when it suits them.
Linca continues the Ghosty app, which the team launched in Prague in 2025. SLAI labs s.r.o. (opens in a new window) operates it.
What Linca does
Answers calls in the firm’s name
When nobody can take a call, Linca answers it as the assistant of that firm, 24 hours a day and in more than 90 languages.
The client speaks to a professional receptionist instead of voicemail, and the inquiry and its details are not lost.
Answers from the firm’s website
Linca reads the firm’s website regularly, so it knows the current prices, services, opening hours and frequent questions. It answers the caller during the call.
The caller gets an answer at once, and the firm does not have to call back. For Smash Room, Linca answers 30 frequent questions.
Sorts calls
Linca knows if the caller is a courier, a new prospect, an existing client, or spam.
The firm sees at once which call is an opportunity and which can wait. Linca blocks calls from 570,000+ known numbers and does not charge for spam or hang-ups.
Qualifies inquiries by your instructions
The firm writes in plain words what it wants to know. Linca asks the caller and qualifies the inquiry.
Before the firm calls back, it knows who it will speak to and what the call is about.
Text message with a link
On the Nonstop plan, Linca sends the caller a text message with a link that fits the call, for example to a booking page or a price list.
The caller can continue alone, right after the call.
Live call, summary within 3 seconds
You can follow the call live in the app. Within 3 seconds after it ends, a notification with the summary arrives on your phone, and the summary also comes by email.
The firm knows who called and what they need, and calls back when it suits it.
How Linca is different
Linca is one of the AI receptionists in Czechia, together with Lorela, Zvednu and KraftunAI. This is how it differs from them and from voicemail.

A fraction of the cost of a receptionist
A full-time receptionist costs more than CZK 30,000 a month, and a virtual reception service CZK 3,000 to 6,000. Linca starts at CZK 290 a month and answers calls around the clock.
The rules of your firm
The firm sets the greeting, the frequent questions and scenarios for each situation, which it turns on by hand, by working hours or from a calendar. Linca then speaks for that firm, not as a general answering machine.
Experience from more than 50,000 calls
Ghosty and Linca have handled more than 50,000 calls. From these calls, the team changed the conversation so that as many callers as possible say what they need.
Privacy without call recordings
Linca does not record calls. It processes the audio in real time, only in memory, never writes it to disk, and deletes the transcript after it creates the summary. It stores only the call summary. Your contact list stays on your phone; to recognise callers, Linca uses only hashed numbers. We store data in the EU, and some technology suppliers are based in the USA. For details, see the privacy policy and the privacy notice for callers.

What customers say
4.9 out of 5 on the App Store, 30 ratingsAll reviews on the App Store (opens in a new window)
It finds out from callers what they need, and I can call them back already prepared for their request. (…) The app is a great replacement for a secretary, who would cost many times more.
You see at once what needs solving, and you can prioritise and end a meeting sooner. (…) For me, a perfect assistant that saved me an hour a day.
Finally I got rid of all those annoying scammers (…) On top of that, it sends text messages with the contacts of the right people at my work, so I save a lot of time myself.
The Linca story
Jiří Zdvomka never liked phone calls. Calls broke his focus, and before a cold call he looked at the number for up to ten minutes before he dialled it.
Before Christmas 2024, he bought the domain ihatecalling.ai and, in two hours one weekend, built an assistant that called a pizzeria for him. The assistant handled most of the call. When the staff asked for a confirmation at the end, it did not reply, and Jiří had to finish the call himself. The pizza arrived, and the pizzeria got a generous tip.
In 2025, this experiment became the Ghosty app, because there was no call screening in Czech for the iPhone.
In 2026, Ghosty got a new name. The call filter became Linca, an AI receptionist for companies and business owners.
