A book only changes you when you act on it. Most reading apps end when you close the book. Open Citadel starts there. It is your citadel of knowledge and self-development: one Library for the books, podcasts and blogs you learn from, and a way to act on what you learn. One Library for everything you learn from Books, podcasts and blogs sit side by side. Move between them in one tap. Free books from Project Gutenberg Browse Gutenberg's shelves, search its catalogue, and download books in the public domain in the United States. Readers outside the US should check the law where they live before they read. Podcasts you can finish Follow shows, search podcast charts and directories, and download episodes. The player has speed control, a sleep timer, chapters and show notes with seekable timestamps. Import your AntennaPod library and keep your place in every episode. Blogs, read in the reader Follow a blog by its feed or web address, or choose from a curated directory. Each post opens in the reader, so you can highlight it, tag it and talk it through with Samwell, just as you would a book. Highlight it. Keep it. Use it. Every highlight, note and tag is saved to your Timeline, a dated record of what you have learned. Samwell, your reading companion Samwell helps you set up your Library, talks through what you read, and turns what you want to change into a goal made of small steps. He checks in using your logs and highlights, so his advice is about your life, not someone else's. On-device Samwell runs on your phone, so he works without a connection. Compass counts consistency, not streaks Log a few minutes a day. Compass measures how often you show up, so one missed day never wipes out the rest. The whole cycle, in one app Read. Highlight. Set a goal. Log it. When the goal ends, Samwell writes down what it taught you, so the next one starts smarter. We assume you can decide what matters. Open Citadel helps you act on it.
