Set the stage. Read together. Grow their universe.

  1. 1

    Set the stage

    Tell us your child's reading level and the things they love, then help them design the kid who shows up in every story.

  2. 2

    Read together

    Snuggle up and take turns. The color-coded focus words turn every re-read into phonics practice. Record audio from your sessions and we'll automatically calibrate next month's book. Prefer no tech? Mark progress yourself after a session.

  3. 3

    Grow their universe

    Next month's book arrives in the mail with the same kid on every page, the same characters they love, and 10 new stories calibrated to their progress.

Inside every book

Built on the science of reading

Aligned with structured literacy and Scarborough's reading rope, every book follows a research-backed 13-tier phonics sequence from short-vowel CVC words to multisyllabic ones. No three-cueing, no guessing from pictures.

After breakfast, the cat sat near the window.

Your child reads the colored words. You read the rest.

Focus words tuned to their level

Focus words are calibrated to your child's exact phonics tier. They read those; you read everything else aloud. The language stays rich, the decoding stays at their level.

Yesterday, the cat sat by the door. Today, Pat had a small rat.

Each color is a different re-read.

Color-coded for re-reading practice

Each story includes word families selected for your child's reading level. Focus words are split into color groups, and every re-read targets a different set. One book, weeks of fresh practice.

Five unique children's book characters — each with their own style, accessories, and personality

Their kid, their cast

They design every detail: hair, skin tone, clothing, glasses, freckles, hearing aids, wheelchairs, whatever feels like them. Then they pick the characters they love (dragons, dinosaurs, robots, fairies) to fill out the world.

After every session

Record audio and we'll handle the rest: automatic progress tracking, a short summary (what went well, what to practice, one tip for next time), and audio deleted after processing by default. Prefer no tech? Mark the words your child got, or say they're ready for the next tier.

A library built just for your child

12 books a year, all set in the same growing universe with the same kid on every page. By year's end, your child has a shelf of stories no one else has, and a year of phonics progress behind them.
