YOM
Read full descriptionHide full description
You can't get through that thick textbook. Pages you have read don't seem to stick. The problem may not be your focus or memory. It is the load of silent reading. YOM is a study app that turns a photographed page into audio, so you can read it through with both your eyes and your ears. ◆ Why Reading with Eyes and Ears Works Silent reading is multi-stage work: your brain recognizes the letters, converts them into inner speech, and only then extracts meaning. The longer you read, the more focus this pre-processing burns. YOM takes over the first half: recognizing the text and voicing it. You simply follow the text with your eyes while the voice reads it aloud. All of your focus goes to understanding and remembering. The voice paces your eyes forward, so you skim less, drift less, and finally finish the material you kept putting down. ◆ Three Steps 1. Snap a page of your study material with the camera 2. Text is recognized on your device (headers and page numbers removed automatically) 3. Press play and follow along with your eyes as you listen Repeat the chapters you want to memorize. On your commute or during chores, review the rest by ear. ◆ Three Easy Ways to Import • Camera: Snap paper textbooks, notes, or documents. Page tilt and shadows are corrected, and the text is recognized • Web articles: Share a URL and only the body is extracted, ads and menus stripped • Text input: Paste any text directly and listen ◆ Read Aloud • Reads aloud with your device's built-in voice engine. Works offline • Multilingual support including English and Japanese ◆ Built-in Translation for Language Learning Listen to foreign-language articles in native AI voice while checking translations with one tap. Set translation as default for specific folders, so your "English Learning" folder stays always-on. Translation runs on-device, so it works fast without network. ◆ Made For • Students preparing for certifications, board exams, professional tests. Read the textbook through and repeat until it sticks • Anyone who reads pages that don't stay in memory • Working adults revisiting textbooks and business books • Researchers and professionals with heavy reading loads • Anyone with dyslexia, eye strain, or who finds long text hard to follow • Language learners building listening skills from real articles ◆ YOM = Yield Own Mind "Cultivate and produce your own intelligence." YOM shoulders the mechanical load of reading, so your mind is free to understand and truly absorb. Start by finishing the material you always meant to read.
