What makes Ludwig different from ChatGPT?

While Ludwig functions as a complete AI assistant, it uniquely provides real-world proof. It shows you exactly how expressions are used in professional sources like The New York Times or academic journals, rather than just giving AI-generated text.

Is Ludwig only for English learners?

No, it is used by native speakers, researchers, and professional writers to find the most appropriate tone, verify rare idioms, and ensure academic or technical precision.

Can I upload my own documents?

Yes, Ludwig allows you to upload PDFs and Word documents to chat with them, ask for summaries, or verify if the language used in your paper matches professional standards.

Does Ludwig have a mobile app?

Yes, Ludwig is available for both Android and iOS devices, allowing you to improve your writing on the go.

Is there a plagiarism checker?

Ludwig focuses primarily on writing enhancement and linguistic search, though its comparison tools help ensure your phrasing is original or properly modeled after verified sources.

Are my chats private?

Yes, Ludwig follows European data protection standards with servers in Italy, Germany, and France. Your conversations are private and not used for AI training.
