The study companion that teaches, not cheats.

chud. is a general-purpose AI built for students first. It explains, checks, quizzes back — and never just hands over the answer.

why does dividing by zero break everything?
Start with what division means — how many times does a number fit into another. Now ask yourself: how many times does 0 fit into 5?

It shows its thinking.

Answers stream in live, with the reasoning open for inspection. You watch the explanation build instead of receiving a block of text — which is how you learn to build one yourself.

Here's what changed in the 2026 FAFSA rules — with where each fact comes from.

It checks the web — and shows its sources.

When a question needs current facts, chud. searches and cites where each claim came from. No confident guessing presented as truth.

Ran code to check the math✓

It reads your files and runs the math.

Drop in your notes, worksheets, or a PDF and work from your actual material. For calculations, chud. can run real code to verify the arithmetic instead of eyeballing it.

No points, no shame — just checking the door is open.

It quizzes you back.

The goal is that you can do it without chud. next time. So it turns explanations into questions, checks what stuck, and raises the difficulty when you're ready.

This is the commitment we call "teach, don't cheat."

No ads, ever. chud. is built to be paid for by the people it serves — never an attention product. Your conversations are not the merchandise.

Ask it something hard.
