About KosGPT

KosGPT is a private, independent project by Martin Hotze. This website is not an AI system and does not answer questions itself. It is the stable gateway to the currently active KosGPT assistant.

The gateway makes it possible to maintain the service, change the underlying AI model when needed, and keep one memorable public address for the project.

KosGPT uses project-specific instructions and a limited set of selected reference information. It is not based on a comprehensive, continuously maintained database about Kos. Its answers depend on the capabilities and limitations of the underlying AI model.

How to use KosGPT

KosGPT works best when your question includes enough context.

Choose your language. You can write in your preferred language and change language at any point in the conversation.
Include the current date for time-sensitive questions. The AI system may not reliably know the actual current date. State the date when asking about timetables, opening hours, events, prices or seasonal services.
Be specific. Include relevant details such as who, when, where and what.
Mention your location and travel dates. Many services on Kos are seasonal and differ by area.
Ask one clear question at a time. This usually produces more precise answers.
Verify important information. Check schedules, prices, availability, medical information, legal information and last-minute changes with the relevant official source.

Instead of: “How do I get there?”

Ask: “I am staying in Tigaki on 15 August 2026. How can two adults get to Kos Town in the evening without a car?”
