“Thank you all at LitLab for helping us create engaged, fluent readers - a skill no one can take away from them. I can't tell you how much it means to me to know our kids are choosing to read (and doing it well) every day.”

Generally speaking, there are three shortcomings with ChatGPT and most "AI decodable generators":
- Not Scope & Sequence Aware – True decodable texts follow a structured phonics progression, ensuring students only encounter taught letter-sound correspondences. ChatGPT does not track or enforce this sequence.
- Inconsistent Phonetic Control – Proper decodables minimize irregular words and multisyllabic words until students are ready for it, and thoughtfully exclude phonetic patterns beyond a student's instructional level.
- No Teacher Support – Decodable texts should support the teacher in understanding which words are not decodable so that they can be explicitly pre-taught, which words are reinforcing the given skill, and so on. They should also thoughtfully include relevant supplemental exercises and practice.
LitLab's Student Practice Platform is the only tool on the market that builds fluency with authentic, curriculum-aligned decodables.
