Paste. Pick a mode. Get the steps.

1. Paste the question

Type or paste it the way it appears on the page: a math problem, an essay prompt, a passage with a question, a sentence in Spanish. Add your grade or course in Settings once and every answer matches your level.

2. Pick a mode

• Explain works the problem step by step, says why each step is valid, gives the answer on its own line, and ends with a check you can do yourself.
• Check my work takes the problem and your attempt. It finds the first wrong step, names the rule, and stops there. You fix the rest.
• Quiz me takes a topic and asks one question at a time, grading each, with a score and one thing to review at the end.

3. Read, then follow up

The answer streams in as it is written. Ask a follow-up in the same chat: “why step 3?”, “give me a similar one”, “say that simpler”. Each message is one question against your daily count.

One strong AI model, chosen for how well it explains, with instructions written for tutoring. We do not name it because it changes when a better one comes out and because the product is the tutoring, not the model. The about page says who runs it and the privacy page what is kept.
