Dodeca Wiki

Ask one question and you get one page — not a chat thread. Tap any word in the answer and the paragraph opens to explain that word in context. Tap a word inside the explanation and it opens again. Every branch you dig stays on the page, and the pages become a wiki that is yours. Dodeca sees knowledge as twelve regions — the twelve vertices of an icosahedron. A vertex lights up as you dig into that region. Spin the shape with your finger to pick a region and it hands you a question you didn't expect. Thirty per region. • Tap any word — not just the three underlined terms; every word in the body is a door • Highlighter — mark sentences in five colors and see them collected on the Knowledge tab • Review — the quiz at the end of each page becomes a card that comes back after a day, three, seven • Ask by photo or voice — photograph a page or just say the question • Graph — pages that share terms link on their own; drag, bounce, pinch • Widgets and sharing — today's question on your home screen; send any text you're reading into Dodeca • iCloud backup — your pages and review cards come back on a new device Your first few pages are free. When you need more, buy Dodeca Light or Dodeca Plus — one question is one step, and digging into words is included. Re-reading, reviewing, and highlighting what you have already made is never charged. Answers are written by an AI model from what it learned in training. Dodeca does not search the web, so it doesn't know today's news, prices, or schedules, and figures can be wrong. It is a tool for understanding ideas, not for checking the facts of the moment. Available in English, Japanese, and Korean. No account, no tracking, and your questions are not stored.
