Free AI tutor for kids aged 7-9 that personalizes lessons in coding and technology through interactive games.
u/Designer_Process_715 · Reddit
I built a free AI tutor for kids that remembers each kid and makes learning feel like a game I'm a software engineer and dad of three. My two older kids were deep in YouTube Shorts and Roblox, and I didn't mind the screen — I minded that they walked away with nothing. So over the last ~7 months I built the thing I wished existed. It's called Aivie Spark. My favorite moment testing it: my son hit a Boss Challenge on a math topic and got stuck. Instead of giving up — or getting the answer

I built the thing. Now I am not sure the base use case is one people will pay for. Founder here. This started as a side learning project to see whether an LLM could answer questions about Excel data, back when they could not do it well.
