Make anyone an expert in anything, in one read. Once lets anyone fully understand any text in a single pass without assuming any background. The idea comes from teaching. I have explained machine learning to people who had never touched it, and jazz and music theory to people who had never studied music, and I noticed that almost anything can be explained in the order of a scientific experiment: you run into a real problem, make a guess, test it, find the best answer, then look back and iterate. Once explains texts that way. You upload a PDF, plain text or Markdown file, or paste a link. The original stays open while the AI explains it out loud, not in the author's order, but starting from the real-world context and why the text exists, then the problem, the attempts, the answer and how it applies elsewhere. Terms come only after the idea is clear in plain words, and background is filled in right when it is needed. When a point comes from the text, the exact sentence lights up as it is spoken, so you can see it is picking out what matters rather than making things up, and anything from outside is labeled with its source. Words a newcomer is likely to get stuck on are underlined with a quick explanation one click away, because in testing I found that when these points pile up unresolved, the whole thing gets less and less clear. Every sentence covered keeps a faint mark, so you know you don't need to read it again. You can read along without voice, or turn on a guided Q&A mode and work things out yourself, typing or speaking your answer, because what you figure out on your own sticks. In most reading that actually matters, AI doesn't save us time. A friend in law school has to know his readings cold, because professors call on students one by one. A friend studying international relations has to understand the key words and details well enough to respond on the spot in debates. A friend who does condensed matter experiments has to keep up with new papers in top journals. A general assistant can summarize or answer questions, but the reader has to steer it, and it can even make up sources. So we end up reading it all carefully anyway, and the AI has added time instead of saving it. Many texts are also not written in an order that fits how people think, and they assume a background, scattering terms and explaining only some of them. People outside a field need the text itself, but in an order that brings it naturally into what they already know. That is what Once gives them. I want to compress three things into one reading session: understanding what the text means, connecting it to your own knowledge, and carrying it over to other things, the inspiration and the creative part. It doesn't take much more time than reading the original yourself. Next, because everyone gets stuck in different places and takes in knowledge differently, Once will bring in each reader's own context and adapt to how each person reads.
