Stemulus: Homework Helper

Turn a photo or typed question into a worked solution, then keep learning with your own study library. Stemulus helps you review math, physics, chemistry and engineering problems at your own pace.

WORK THROUGH THE STEPS
Capture a problem with your camera, choose a photo, or type it yourself. Review the problem before sending it, then follow the explanation and mathematical notation. Where available, arithmetic checks provide additional evidence about the result. AI answers and checks can be wrong; review the reasoning and verify important results.

BUILD A STUDY LIBRARY
Save worked problems on your device, organize them into assignments, and mark what you want to revisit. Your saved work remains available offline. An internet connection is required to generate new answers and study material.

PRACTICE FROM YOUR OWN WORK
Create study guides and practice questions from saved problems. Try an answer, use progressive hints, and review feedback alongside the worked answer.

CHOOSE WHAT YOU SEND
Stemulus asks for consent before sending problem content to its AI services. You can withdraw consent in Settings. Optional answer reporting lets you review the message and any included excerpt before sending it.

OPTIONAL PURCHASES
Start with an initial check allowance. Optional weekly subscriptions include 100 checks per rolling seven days; purchased credit packs add more checks. Current prices and recurring billing terms appear before purchase through Google Play. Manage subscriptions in Google Play.
