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.`

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 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 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".

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.

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.

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.
