Koji guides kids with questions instead of handing them the answer. Here’s how it works, plus the copy-paste setup to turn the AI you already use into the same kind of Socratic tutor.
In May, Brilliant co-founder and CEO Sue Khim launched Koji, an AI tutor built on the Socratic method. Instead of handing your kid the answer, it guides them one question at a time until they work it out. In her launch thread on X, she shared a stat that stops you cold: 90% of parents think their kid is at grade level, and only about 28% actually are.
When AI just hands kids the answer, they skip the part where thinking gets built. A tutor that makes them reason is the opposite of a homework shortcut. And you don’t need a new app to get it. You can set up the AI you already use this way today.
Before You Start
Claude’s terms require users to be 18 or older, so set this up in your own account and sit with your kid while they use it. ChatGPT allows ages 13 to 17 with a parent’s permission and has parental controls for teen accounts.
If your kid already uses AI for homework, paste this at the top of the chat before they start. Fill in the brackets first.
That flips the AI from an answer machine into a patient tutor for one session. To get it every time without re-pasting, build it as a Claude Project.
A Project keeps its instructions across every chat inside it, so the tutor already knows your kid’s grade and subjects. Projects work on every plan, and the Free plan gets up to five. (How Projects work)
01
Create the project
In Claude, click Projects in the left sidebar, then New project. Name it something like "Homework Tutor."
02
Paste the instructions
Open the project’s instructions, paste the prompt below, fill in the brackets and save.
03
Start every session inside it
Each new chat in the project starts as the tutor. Your kid types what they’re working on and it takes it from there.
01
Upload what they’re studying
Drop their worksheet, reading or textbook chapter into the project files (or snap a photo into the chat). The tutor then asks questions about the exact material instead of generic ones.
02
Set the difficulty
Say "harder" or "gentler, they’re getting discouraged" and it adjusts. You’re the coach behind the coach.
Other Options
ChatGPT has a built-in study mode that works the same way. In a new chat, open Tools and pick Study and learn. If you want a polished app built around this, Koji is built into most of Brilliant’s math and coding courses, where it sees the lesson your kid is on and responds in real time.
