Frequently Asked Questions

Everything you need to know about Refuerzo.ai

Refuerzo.ai has no limits. You can ask for help as many times as you want. It never gets tired of helping you!.

Refuerzo.ai doesn't just give you the final answer. Our AI analyzes your process step-by-step, identifies exactly where you went off track, and offers hints or partial explanations so that you are the one who completes the learning.
Even if you answer correctly, the AI provides a detailed explanation to help you solidify the concept.

Of course! You can use your phone's camera or webcam to upload a photo of your notebook directly. The AI recognizes handwriting and handwritten formulas with high accuracy. If you use a webcam and a face appears in the frame, it is blurred automatically before anything is stored; and if the sheet is not visible in the photo, the image is not stored. If you use a computer more than a phone, we recommend a webcam like this one.

The clean, minimalist design is intended for studying without distractions.
