Colo Learn is a science chat for kids aged 8 and up. Two friendly turtle characters take turns answering science questions in plain words.
No data collection. Conversations live only in this browser tab and clear when the tab is closed. The turtles do not give medical advice and steer away from heavy topics.
Built on the same science engine that powers Colo, a research tool for biomedical researchers.
