Reading isn't just about literacy; it’s about brain architecture. In the first five years, the brain forms one million neural connections per second. Shared reading, especially when paired with a familiar voice, activates the visual association cortex more powerfully than a stranger's voice, creating an emotional "tag" that helps store information in long-term memory.
It refers to the "just right" level of stimulation for a child's brain. Research from Cincinnati Children's Hospital shows that while animated videos "collapse" brain connectivity and audio-only can strain it, the combination of static illustrations + audio (the Lestori format) creates the strongest integration across language, attention, and self-reflection networks.
Lestori is a screen-free educational ecosystem that transforms physical books into multisensory learning experiences. By adding audio interpretations and guided discussion tools to real books, we help children develop deep comprehension, emotional regulation, and original thinking skills.
Lestori is designed for children at various stages of development, including early readers building foundational literacy, multi-lingual families, and students with visual impairments or dyslexia who benefit from high-quality audio and specially formatted read-along text.
Unlike mechanical reading, deep comprehension requires connecting language, imagery, memory, and inference simultaneously. Lestori’s format uses static illustrations paired with audio to engage the brain’s self-reflection networks, giving children the "cognitive space" to form their own mental images and process meaning rather than just decoding words.
Vicarious resilience is the ability to build emotional strength by observing a character’s struggles and triumphs from a safe distance. Lestori hand-selects books and provides guided questions to help children process these challenges, equipping them with the perspective needed to navigate real-life pressures.
Neurological research shows that a parent’s voice boosts visual cortex activation and long-term memory encoding more powerfully than a stranger's voice. Even if your reading isn't "perfect," the emotional bond and familiar cadence significantly enhance your child’s learning and engagement.
Lestori’s approach is grounded in a consistent body of research showing that early, high-quality reading experiences shape language, cognition, and emotional development. First, daily shared reading is associated with a major early vocabulary exposure advantage (often cited as a ~1.4 million word gap by age five), supporting Lestori’s emphasis on frequent early reading: Logan et al. (2019), Journal of Developmental & Behavioral Pediatrics.
Second, Lestori’s format choices (audio with static illustrations, child-led pacing, guided reflection) align with MRI-based findings that passive screen-heavy formats are less supportive of integrated comprehension networks, while reduced early screen burden is also linked to developmental risk considerations: Upstate KIDS Study, JAMA Pediatrics (2019) and related pediatric neuroimaging context such as Hutton et al., JAMA Pediatrics.
Third, Lestori’s “beyond literacy” claims (empathy, regulation, behavior, resilience) are supported by large-scale evidence that early reading for pleasure correlates with better cognitive performance, mental wellbeing, and favorable brain structure markers in adolescence: Cambridge University / NIH ABCD Study (2023).
Lestori is designed to work with any physical book you already own. You can turn your child’s entire existing library into a brain-building ecosystem without needing to buy proprietary "smart books" or "smart pens" using our Tappi stickers.
No. Lestori is designed to be simple and accessible. It works with any smartphone or tablet. By using our Tappi technology, you link your voice recordings to specific physical books, allowing your child to lead their own reading experience using devices you already own.
A Tappi is a patented Lestori smart sticker found on the cover or inside of a book. It acts as the digital bridge that allows the Lestori app to recognize the specific book and instantly play the associated audio recordings and educational content.
A Student/Child Account is a simplified, neuro-inclusive interface designed for your child to listen and follow along, focusing purely on the book without distracting "app" features. Your child may have already been given access to a Student account via their school.
A Parent Account is the "control center" where you can record stories, manage your kids reading and manage your family settings if you have multiple kids. If you don't yet have a Parent account, you can set one up by tapping the Settings button on any book, and then choosing "Parents Section".

Many of our users receive their first Lestori-enabled books directly from their school library or classroom. You can check the "Check if your school has Lestori" section on our homepage, or ask your school administrator about Lestori.
Your profile and all the recordings you have made for your child remain available to you as long as you maintain an active Lestori subscription, ensuring that your family’s library grows with your child.
Lestori was built with Neuro-Inclusive Design. For children with ADHD, autism, or dyslexia, the "shame barrier" often blocks learning. Lestori allows for child-led pacing, the audio stops and starts instantly as the child turns the page, removing the time pressure and judgment often found in group reading sessions.
Yes. For older children or those with dyslexia, the Lestori app offers a "read-along" mode with specially formatted fonts and colors designed for easier reading. Users can also adjust reading speeds, font sizes, and toggle pronunciation guides like Pinyin for Mandarin.
Yes. Lestori Screen-Free technology was initially developed to help children with visual or cognitive impairments access physical books. By augmenting the tactile experience of a book with high-quality audio narration, we help bridge the gap toward functional literacy for every child.
Lestori is an augmentation ecosystem, not a replacement. Because our technology requires the user to have the physical book in front of them to function, we actually drive physical book engagement and sales. We don't distribute digital versions of the books; we provide enhancements that makes the physical copy more valuable to the family.
We advocate for "Eyes on books, Ears on Lestori." While a device facilitates the audio, the screen is not the focus. Our interface is designed to be "screen-passive," meaning once the audio starts, the child’s visual attention remains 100% on the physical pages, exercising the visual association cortex rather than overstimulating the brain's reward centers with animations. Our upcoming Lestori Screen Free stand makes it even easier to keep the child's attention on the book.
You can navigate pages in several ways:
on the left and right sides of the page to go to the previous or next page
in settings, it will automatically play the next page after the current page is finished
in the center of the page to start audio playback
to pause the audio
to restart the current page's audioAutoplay automatically plays the next page when the current page's audio finishes. You can toggle this feature on or off by tapping the Autoplay button in the Settings panel.
Click the settings icon (gear/cog) 
in the top right corner of the page
Some books have multiple narrators!
(slowest), speed 
(normal), or speed 
(fastest)Pinyin displays pronunciation guides for Chinese characters. This feature is only available for Chinese books.
Karaoke mode displays the text of the page and highlights words as they're being spoken in the audio. This helps you follow along with the narration.
To turn it on or off, you can tap "show text" at the bottom of the screen, and the text panel will slide up
Alternatively
setting on or offTo change the text size, first click on Show text, then click the text size button 
to toggle between three sizes of text.
Or, you can
(smallest), size 2 
(medium), or size 3 
(largest)If dictionary access is enabled for your account:
Yes! You can view pages in fullscreen mode. In fullscreen mode, the text of the book is broken into fragments. You can play back the audio for each fragment, or even translate the text to your preferred language.
Yes! The book automatically saves your progress and will return you to the last page you were reading when you come back.
At the end of each book, Lestori may show guided reading questions to help spark conversation and deepen comprehension. They are designed as open-ended prompts (not tests), so there is usually no single "correct" answer. You can discuss them in any order, skip questions, or revisit them later. These prompts are meant to support critical thinking, language development, and parent-child or teacher-student discussion after reading.`
