Sage reads your uploaded source and answers questions from it, citing the exact passages it used. Like having a tutor who actually read the textbook.
Sage is GoodOff’s AI tutor. It reads your uploaded source — a PDF, notes, lecture, or video — and answers questions from that material, citing the exact passages it used. Unlike general-purpose chatbots, every answer is grounded in your own content, so you can trust the source. It supports text, image, voice, and file inputs, and saves conversation history so you can pick up where you left off.
Every response cites the exact passage from your source. No hallucinated facts — you can check the reference yourself.
Upload a PDF, notes, slides, audio, or a video. Sage reads it all and becomes your subject-matter expert.
Ask questions via text, voice, image, or file — whichever is fastest. Take a photo of a diagram and ask Sage to explain it.
Your chats are saved so you can return to a tricky topic later without re-explaining the context.
Switch to Research mode for deeper, longer-form analysis when a quick answer isn’t enough.
Four advanced modes — chat, solve, question generation, and guided learning — for when you need more than Q&A.
Add a PDF, notes, slides, audio, or video to your GoodOff library.
Inside your library item, switch to the Sage tab to start a chat grounded in that source.
Type, speak, or send an image. Sage reads your material and responds with a cited answer.
Follow up, switch to Research mode, or try DeepTutor for guided learning.
Constraining AI answers to information present in a specific document, rather than general web knowledge. This reduces hallucination and makes every claim verifiable.
A technique where the AI retrieves relevant passages from your source before generating an answer, so the response is anchored in real content.
The learning strategy of testing yourself on material rather than passively re-reading it. Asking Sage questions about your notes is a form of active recall.
A reference to the specific passage, page, or section of your source that supports the AI’s answer. Lets you verify accuracy instantly.
Upload your lecture slides and ask Sage to quiz you on the key concepts, then check each answer against the source.
Drop in a dense paper or textbook chapter and ask Sage to explain the parts you don’t understand, in plain language.
Load multiple papers and use Research mode to synthesize findings across sources with citations.
Need to find a specific fact in a long PDF? Ask Sage instead of scrolling. It returns the passage and the location.
Upload a PDF or your notes, open Sage, and get answers grounded in your own material — with citations.
