About Howcomet

A curiosity app for 5-14s. Every question gets an answer, then a check that proves they understood it, then a star that fades until they come back to it. Pictures that move, so it makes sense at a glance. A map of everything you have learned, one question at a time. Handing an AI to a child is a fair thing to worry about. If one is refused, your child is told you will see it.

About VibeKnow

Free AI video generator that turns documents, PDFs, PPT, and URLs into polished videos with voiceover and visuals, for explainers, demos, and training. We handle the full production stack, not just one piece. You stay in the parts that need your taste; we handle the rest. It writes the script first, then builds every visual around the story. You shouldn't also have to learn Premiere, hire a voice actor, design title cards, color-grade, and re-export six aspect ratios, just to publish what you already finished.
