Onhand
Stop pasting into chatbots. Onhand explains the page itself.
Chatbots pull you off the page and hand back an answer that's often ungrounded in the source you gave them. Onhand, a Chrome extension, stays in the material while answering questions, highlighting the line, leaving a note in the margin, and explaining it on the page you're already reading. Learning mode guides you to the answer instead of just revealing it, and voice lets you ask follow-ups in real-time. Onhand is for students, researchers, and deep readers. It's free to use and open-source.
I created Onhand as a student who was annoyed by chatbots not helping me learn. They moved me away from source material and were too quick to give me the answer.
Onhand lives in your browser, answering questions directly in the page you're confused about. It highlights relevant text and adds notes to the page. The full answer directly cites these highlights/notes.
Learning mode adds the principles of pedagogy to Onhand. The agent doesn't directly give you the answer, instead highlighting hints from the page and asking you leading questions. Voice mode allows Onhand to act as a tutor, answering any follow-ups that you pose to it.
Onhand can use multiple open pages to answer queries, and it can even use your browser to find new relevant pages. Sessions are saved, so you can close and reopen them later with highlights and notes persisting.
