We want to be plain about this.
Where facts come from
Many lessons use made-up characters and places, such as a pretend robot or a made-up planet.
When a lesson states a real-world fact, our rule is that the fact needs a source on record. The source should be a primary one, such as a science agency or a museum.
Who writes what your child sees
The Dilly team writes every lesson, mission and companion line ahead of time. Nothing is made up on the spot, and nothing your child types changes what was written. There is no chatbot and no AI in Dilly. See Is there AI in Dilly?
Where sources are shown
A source shows once, in a quiet line at the end of a mission. It also shows in the learning report. It does not clutter the lesson.
Has it been reviewed?
Not yet by an outside expert. Every lesson is marked "unreviewed" in our files, and nobody has signed any of them off as checked. We do not call them verified.
A few skills about fairness and persuasion also need a safety check. Until then, the report leaves out their wording for grown-ups.
Found a mistake?
