Abstract
We present FreeTxt, a free, web-based tool supporting analysis and visualisation of multilingual qualitative survey data, with a focus on low-resource languages. The system integrates corpus linguistics with NLP methods, currently handling English and Welsh, with plans for Vietnamese expansion. Key features include semantic tagging, sentiment analysis, keyword visualization, and summarization, validated through testing with cultural heritage institutions.
