Anki add-on: Hypnagog – Subliminal Learning Visualizer

Hypnagog – Subliminal Learning Visualizer Hypnagog turns your Anki cards into a focused, full-screen learning experience. Instead of the standard card-by-card review, it presents your facts as a rapid visual sequence — priming your memory through repeated, low-effort exposure. What does it do? Select a deck, hit start, and watch your cards unfold: Key terms flash briefly , preparing your brain before you consciously read Full text appears with the important parts highlighted in color Cloze answers reveal one by one , giving you a moment to recall before seeing the answer Basic cards show the question first, then the answer fades in below The text fades out with a gentle afterglow, reinforcing the visual trace After all cards, the deck reshuffles and repeats. You control the pace — pause anytime with the spacebar to think, then continue. Two visual modes Press 1 for a clean, minimal look — just text and color on black. Press 2 for the full atmospheric experience — CRT scanlines, floating particles, ambient audio tones that respond to each reveal. Inspired by the Polybius aesthetic. Works with all card types Cloze cards — Target answers start as [...] and reveal sequentially. Each answer gets its own color. All other information stays visible so you always see the full context. Basic cards — The question appears first in white, then the answer fades in below in gold after a short delay. Clean separation, easy to follow.
