About

Onhand is a page-grounded AI tutor for learning and research. Open the side panel on any webpage or PDF, ask a question, and Onhand answers from the material in front of you.

It can highlight relevant passages, add margin notes, save study sessions, and help you check your understanding without switching to a separate chatbot. Voice mode lets you ask aloud while keeping your eyes on the page.

Onhand is designed for students, researchers, and deep readers who want explanations anchored to the source they are reading.
