Most AI decodable tools miss the mark. LitLab doesn't.
ChatGPT and even most K-12 AI tools are unaware of skill progressions, include irregular or multisyllabic words too early, and offer no guidance as to how the text matches phonics programs.
The LitLab platform was built on a proprietary Scope & Sequence Alignment engine. This unique system breaks down words into phoneme <> grapheme correspondences, and leverages models that respect the progression and rules created by each phonics program, resulting in highly decodable text.
| ChatGPT / K-12 AI tools | LitLab Decodable Generator |
|---|---|
| Ignores phonics progression | Follows precise scope & sequence |
| Irregular, multisyllabic words show up early | Controlled vocabulary at each level |
| No instructional context | Built to support explicit instruction |
Decodability Score (%)
In head-to-head tests, LitLab's generators scored an average of 93%+ on decodability, compared to ChatGPT's ~35% (even with good prompting).
Practice that's more precisely aligned than any other program.
LitLab is the only foundational reading supplemental that turns your existing core phonics program into rigorous fluency practice.

I love being able to customize the decodables. The students were amazed at their selections being quickly inserted into a decodable they could read within seconds. The decodables were really enjoyable for the children to read!

It was a hit! The kids loved being able to use their creativity while strengthening their reading skills with decodables. LitLab offered interactive features which made the experience truly engaging.

They were excited to read their stories, find their friends' stories afterwards, and then even read random stories with interesting titles. There isn't this excitement about Epic. They're not like, “Look at this cool book that I read,” but today they were like, “Oh my gosh, read this one!”

LitLab is a really engaging tool for students to create their own decodable books for fluency and skills practice!
