Lium (https://www.lium.ai/) connects complex data sources (databases, files, APIs, etc.) and responds in natural language with AI-generated analyses, scripts or tools.

The main interface is a chatbot: instruction on connected data and choice of model (GPT, Claude, etc.).
Analysis in Python, visualizations in html.

Every analysis, visualization, or produced dataset is saved as an “artifact” and shared in the workspace. The “spaces” mode allows collaborative work.

Note: Target audience (researchers, data scientists, etc.).

Free version: limited data connections, standard queries, and 10 messages per month.
