Learning a language is hard. Studying a foreign language requires hundreds or thousands of hours, and everyone is busy. Prismatext offers the first effortless method for learning a language: blended-language reading! Now an hour spent reading is an hour spent learning. Using a science-backed method called "Diglot Weave", Prismatext books blend the most useful foreign words and phrases into modern and classic literature for context-based language learning. Prismatext translates more and more of the book you're reading into your target language. This allows the reader to naturally acquire new foreign vocabulary and grammatical rules. See phrases used in-context for improved recall. Repetition and incremental phrase addition allow you to easily learn new words at your desired pace - you can adjust the density at will. Beginner? No problem - tap the translations to see definitions and explainers, as well as the proper pronunciation of the phrase. Advanced? Try a higher level setting and a higher density for faster uptake. Skip the boring practice exercises, games, and gimmicks.

More than 15% of the population has great difficulty reading and understanding texts (ADHD, dyslexia). We have received feedback from people with ADHD that thanks to Bionic Reading® they immediately understood the content of various texts the first time they read them, which was impossible without Bionic Reading®. COMMENTS AND FEEDBACK. Jessica: “Having ADHD and processing issues means that I read very slow because my brain can’t focus on the words enough to both read them and process what they mean at a decent pace. Using Bionic Reading® has allowed me to feel functional and productive when I’m reading something lengthy – it’s such a GAME CHANGER!” Lisa: “I have not read fiction for 20 years. I read what I have to read. It almost hurts my brain to read regular type. But now I will be reading fiction again! Bionic Reading® works for me and I can read 2–3 times faster! AMAZING! This is a LIFE CHANGER! Thank You!” Patrick: “OK, Bionic Reading® is the real deal. I already read quickly and this doubled it.” Reaction from Daniel: “Holy smokes you’re not kidding!” Carla: “WOW! I could read quickly and fluently using Bionic Reading®. Doing this helped me understand the context of the paragraph much better than when I have to squint and focus on each word, which tires me out and I lose focus. Bionic Reading® is brilliant!” Nestor: “Your tool is gorgeous, It’s helping me a lot. My sight is reduced because one of my transplanted corneas has become opaque and Bionic Reading® is helping me a lot to read easier and comprehend faster.” TYPOGRAPHY. DESIGN. SWITZERLAND.
