How to choose the right reading level
Age is what everyone sorts books by, and age does not measure reading. This film shows how every story in the library is scored by the SESL© algorithm and mapped to CEFR, and how to filter by level, age and theme to find something your child can actually read.
Subtitles
The film is in English. Read along in your language — or switch subtitles off.
Every parent asks the same question.
Can my child actually read this?
The book says ages five to eight.
Somebody decided that.
Nobody will say how.
Age is what everyone sorts by.
Age does not measure reading.
Two eight-year-olds can be two reading
years apart, both perfectly normal.
A teacher has thirty of them, and one shelf.
So we measure instead.
Every story is chosen by a person, then scored by our SESL©
algorithm, and mapped to CEFR — Pre-A1 through B2.
Nothing about your child.
Everything about the words.
The Story Library.
Reading level and age sit on the same button — start with whichever you know.
Above it, the SESL© score itself —
a hundred-plus measurements of the text, in five bands.
It is the one we would use.
Twelve themes, and filters stack — so you can ask
for something easy, and brave, and full of animals.
Every card carries its score, level and age.
Before you open it.
Less romantic than a bookshop.
Considerably better informed.

2:30What is StorySparkle?
The full picture in two and a half minutes: why so many children struggle reading fluently and expressively, what makes StorySparkle different from an AI story generator, and how levelled stories, video narration, the Story Maker, the Text Checker and progress tracking fit together.
1:37How read-along works
Expression is not something a child can be told — it is something they watch. This film shows the video narrator, the synced word highlights, the slow-down control, tap-any-word lookup with translation, and dyslexia-friendly reading.
1:28How to make a custom story
Most story generators will cheerfully hand a six-year-old Dickens. This film shows the Story Maker: your child invents the world, character, goal and twist, you set the reading level, and the level decides vocabulary, sentence length and story length before a word is written.
1:33How to check if a text is the right level
Standing in a bookshop, the available methods for choosing a book are the pictures, the long words, and a child who says yes to anything with a dragon on it. This film shows the Text Checker: paste any text or photograph a worksheet, and get a SESL© score, a CEFR level, and a rewrite if it is too hard.
1:26How to track reading progress
Six weeks in, every parent asks whether a reading app is working — and from the doorway, a child reading and a child staring look identical. This film shows what StorySparkle actually measures: a clock that runs only while they read, levels against CEFR, the daily habit, and every word read.
