AI Tutor

Can you explain long-term potentiation simply?

Long-term potentiation (LTP) is how your brain strengthens connections between neurons when they fire together repeatedly. Think of it as "neurons that fire together, wire together" — the more you revisit a concept, the stronger that neural pathway becomes.

Is that related to spaced repetition?

Everything you want to know.

The Duetoday Chrome Extension is an AI study tool that lives in your browser sidebar. It can read any webpage or YouTube video you're viewing and instantly generate flashcards, quizzes, mind maps, bite-sized courses, and an AI tutor tailored to that specific content — without switching tabs or copy-pasting anything.

Yes — this is one of its best features. When you're on any YouTube video, Duetoday adds a "Learn with Duetoday" button below the video. Click it and the extension opens the sidebar, transcribes the lecture, generates a summary, and builds flashcards and quizzes from the transcript. It works on lecture recordings, Khan Academy, MIT OpenCourseWare, and any other educational video.

The extension is available for all Chromium-based browsers — Google Chrome, Arc, Brave, Microsoft Edge, and Opera. A Firefox version is on the roadmap.

Yes. The extension is free to install and includes free generations for all tools (flashcards, quiz, mind map, course, and AI chat). A paid plan unlocks unlimited generations and syncs everything to your full Duetoday canvas with advanced features.

No. Duetoday only reads a page's content when you explicitly click "Import Page" or use the YouTube button — never passively in the background. We do not collect your browsing history, track which sites you visit, or scan pages you haven't chosen to import. See our privacy policy for full details.

ChatGPT gives generic answers from the internet. Duetoday's AI tutor reads the exact lecture, article, or video you're studying and answers from that content. The flashcards and quizzes are generated from your material, not a generic topic overview — so they match your professor's phrasing, your course's depth, and the specific examples you've been taught.

Yes. Medicine, law, engineering, economics, history, computer science, languages — anything you can study on a webpage or YouTube video. The AI adapts to your material automatically.

You need a free Duetoday account to use the AI tools (so your study materials can be saved). Creating an account takes under a minute — just an email and password. Everything you generate in the extension is saved to your Duetoday canvas automatically.
