Need one passage on this week’s topic? ChatGPT can write it, and so can ReadTheory’s free AI worksheet generator, which adds the questions and answer key and lets you assign the worksheet to your class. Want each student practicing at their own reading level every week? ReadTheory’s adaptive practice updates each student’s level after every quiz and keeps a record of their progress. ReadTheory is free for teachers.
The short answer
- ReadTheory is adaptive reading comprehension practice for students in grades 1 to 12.
- Students read a passage and answer comprehension questions. After every quiz, ReadTheory moves the student’s reading level up or down and picks the next passage to match.
- A ChatGPT passage is written once, at the level you type into the prompt. It does not know how your students did on the last one.
- ChatGPT keeps no record of each student’s results. ReadTheory gives teachers progress reports on every student, on the free plan.
- Need a worksheet on a topic of your own? ReadTheory’s AI worksheet generator writes a passage, multiple-choice questions and an answer key for any topic, grades 1 to 12. You can assign it to your class inside ReadTheory.

What doing it yourself with ChatGPT takes
To give a class of 30 level-matched practice with ChatGPT, a teacher has to:
- Find each student’s reading level.
- Write a prompt for each level.
- Read every passage and check every answer key.
- Hand out the work and collect it.
- Grade every answer.
- Write down each student’s score.
- Decide each student’s next level, and start again next week.
ReadTheory does steps 1, 2, 3, 5, 6 and 7 for you. You set up the class once, and students practice.
Need a passage on this week’s topic?
ChatGPT is a good choice for a one-off text: a short passage about the topic your class is studying this week, a warm-up, or a second version of a text you already use. ReadTheory’s free AI worksheet generator does the same job with no prompt to write. Type a topic and pick a grade from 1 to 12. It writes the passage, multiple-choice questions and an answer key. Read it and change what you want, then download it as a PDF or assign it to your class inside ReadTheory. Use the worksheet generator for this week’s topic, and ReadTheory’s adaptive practice for each student’s regular practice.

Why level-matched, steady practice matters
In our data on more than 500,000 students, how much a student practiced barely predicted their reading growth. The strongest predictors were pace and consistency: reading carefully, and practicing steadily over time. ReadTheory keeps each student at a level where steady practice is possible, so you can focus on the rhythm.

Questions teachers ask
Can ChatGPT replace ReadTheory?
For a single passage, it can, and so can ReadTheory’s free AI worksheet generator. For ongoing practice, no: ChatGPT does not track each student’s level, pick their next passage, score their answers, or keep a record of their progress. ReadTheory does all four.
Can ReadTheory make a worksheet on my own topic?
Yes. The free AI worksheet generator writes a passage, multiple-choice questions and an answer key on any topic, for grades 1 to 12. You can download it as a PDF or assign it to your class inside ReadTheory.
Is ReadTheory free?
Yes. Teachers can use ReadTheory free. The free Basic plan covers one teacher and up to 30 students, with a weekly quiz limit. It needs no credit card and does not expire.
What grades is ReadTheory for?
Students in grades 1 to 12. It is also used with English learners, special education students, and adult learners. It is comprehension practice, not a phonics program and not a full ELA curriculum.
How does ReadTheory set a student’s level?
After each quiz, the student’s level moves up or down based on how they did, and holds steady in between. Accuracy is the main driver.
Do teachers pick every passage?
No. ReadTheory picks most passages for each student automatically. Teachers can also assign a specific passage to a class or a student.
What happens to student data?
ReadTheory does not sell student data.
