A written tutor example
Example: a 4 kg cart is pulled with 18 N while friction opposes it with 6 N. You divided 18 by 4. Choose the kind of help you would ask for.
Choose the cart as your system. Which forces point right, and which point left? Keep their signs when you add them.
This is an authored demonstration, not a live AI response. The live tutor requires Pro and a connected ChatGPT account. You choose what context to include and press Send yourself. Generated explanations can be wrong.

A check means the provider offers that feature. Standard (non-promotional) prices from each provider's own site, 7 August 2026; Kaplan and Manhattan Prep don't publish base prices. The big platforms lead on question-bank size and video courses, which this table doesn't try to match — it highlights where Keiko is different, not a full feature-by-feature comparison.
