ChatGPT in Serbian, and what a business needs on top

ChatGPT writes in Serbian well enough to draft an email, a menu description or a reply to a guest. What it cannot do on its own is know which answer is true for one particular business, and in this region that gap shows up fast.

Montenegro's 2026 VAT law raises the registration threshold to 30,000 euros and does not apply until the country joins the EU, so the older 18,000 euro threshold is the one that governs today. A model that reads the newest document gives a small business the wrong number, confidently. Pitaj answers legal questions in plain language from dated articles and procedure guides, and a hard rule blocks any fee, deadline or article number that has no traceable source.

The same rule runs the hotel agent. It answers guests from the property's own knowledge, refuses to invent a price or a vacancy, and hands the thread to a person when it does not know.

Language is the other half. Kalo, a calorie tracker built for Serbian, Croatian, Bosnian and Montenegrin, reads a photo of a plate and answers in the user's own language, with a prompt tuned for burek and ćevapi and no English anywhere in the interface.

So ChatGPT in Serbian is a good writing tool for a business. An assistant that answers customers needs the business's own data, a list of what it must never guess, and a person behind it, which is what the AI systems page builds.
