MindMargin

The antidote to letting AI think for you: study flashcards, SAT and GRE words, and games while ChatGPT, Claude or Gemini writes.

MindMargin turns the seconds you spend waiting on an AI chat into a quick study break. When you ask ChatGPT, Claude or Gemini a question, a small card appears in the corner of the page while the answer is being written. Review one flashcard or play a short word game, then get back to your chat when the reply is ready. What you can study Your own flashcards. Paste in a set from a spreadsheet or import a CSV file. Cards are scheduled with spaced repetition, so the ones you are about to forget come up first. SAT and GRE vocabulary. We wrote 300 SAT words and 500 GRE words, and you can add either set with one click. Short word games that fit into a few seconds of waiting. For longer sessions, the study page lets you review with flashcards, multiple choice or typing. A daily goal and a streak help you keep going. Read-Along can read the AI's answer aloud and highlight each word, using the voices already on your computer. Private by design Everything runs in your browser. Your cards, progress and settings stay on your computer. MindMargin sends nothing to us or anyone else, and there is no account to create. Works on chatgpt.com, claude.ai and gemini.google.com. Free.
