About
ReaderStudio is built by a teacher who kept running into the same problem: the decodable readers a child needs at the start are almost never about anything. They are phonically careful and intellectually empty.
The premise here is that restricted vocabulary does not have to mean restricted ideas. A book about a food web can be readable by a child still working through letter-sound correspondences — it just takes more care in choosing the words.
How the books are made
Every species carries its own record
What it eats, where it lives, what its young is called, what sound it makes. Facts are verified against published sources before anything is generated from them.
Sentences come only from that record
A sentence about a frog is built from the frog's data. Nothing is borrowed from a shared pool, which is how you end up with a pig that has fins.
Missing facts mean missing pages
If we cannot verify what an animal eats, the book has no diet page. A shorter book is better than a confident wrong one.
The phonics stage is computed
Each book's stage is derived from the spellings on its pages. Where a word needs a correspondence our sequence does not teach, the book reports that rather than guessing a number.
Where it is up to
The engine works and the first ecosystem — a pond — is complete. The phonics sequence is being aligned to a published scope and sequence so that a stage on the cover means something a teacher can check against their own programme. Until that is done, books that carry higher-level science vocabulary are marked as stage-undetermined rather than given a number we cannot defend.
If you teach early reading and want to tell us what would make these useful in your classroom, we would genuinely like to hear it.
