AI text leveler
Attach a reading and tell Sparky who will read it. Sparky rewrites it at that reading level, keeps the facts and the key vocabulary, and gives you a document to print or send to Google Docs or Word.

How the text leveler works
Add the text and name the readers
Attach the reading or paste it in, then say who will read it: "my 5th graders" or "9th graders reading at a 6th grade level".
Check the leveled version
Sparky rewrites the text in a document beside the chat, with shorter sentences and plainer words around the same facts. Ask for changes, or click into the document and edit it.
Print it or export it
Copy the leveled text, print it, save it to Google Drive as a Google Doc, or download a Word file.
What you can do with the text leveler
Lower or raise the level
Make a dense article easier for students who struggle with it, or rewrite a simple text with richer sentences for readers who need more challenge.
Several levels from one text
Ask for two or three versions of the same reading. Each one is labeled, and every version covers the same ideas, so the whole class can discuss it together.
Key words kept
Sparky keeps the words students need for the subject, like "photosynthesis" or "tariff", and can define them in a list at the end instead of swapping them for easier words.
Passages at any reading level
With no text to start from, name a topic and a level, like "the water cycle for 3rd graders". Sparky writes an original reading passage and defines the key words at the end.
Ways teachers use it
Mixed-ability classes
One article at two or three reading levels, so every group reads the same content and joins the same discussion.
Level it and translate it
An easier English version for English learners, with a copy in their home language to read alongside it.
One student's reading goal
A version of today's reading at the level named in a student's IEP or reading plan, with the content the class is learning left in.
Primary sources
A founding document or an old letter rewritten in today's English, so students can follow the argument before they work with the original wording.
Data privacy
Safe to use with student work

Frequently asked questions
Is the text leveler free?
Yes, it's free for teachers.
What kinds of text can I level?
Attach a PDF, a Word file, slides, a photo of a textbook page or a link, or paste the text into the chat. You can also import a file from Google Drive or OneDrive. Flint reads the printed text in scanned pages and photos. A link has to open without a login, so an article behind a paywall won't work; download it and attach the file instead.
Can it change a text to a Lexile level?
Sparky doesn't measure Lexile or other readability scores. Name a grade level, or describe your readers, such as "7th graders who read at a 4th grade level", and Sparky writes to that. If your school tracks Lexile measures, check the leveled text with the tool your school uses.
Does leveling change the facts?
It shouldn't. The text leveler tells Sparky to keep the text's main ideas, facts and key vocabulary, and to change how sentences are built, how much each one packs in and the support around hard ideas. Read the leveled version before you hand it out, as you would with any rewrite.
Can I make more than one level from the same text?
Yes. Ask for the levels you need, such as on grade level and two grades below. Sparky labels each version so you can hand the right one to each group. Flint vs Diffit compares Flint with an app built for leveled handouts.
Can I download the leveled text?
The document has buttons to copy it, print it, save it to your Google Drive as a Google Doc, or download it as a Word file. For a PDF, press Print and choose Save as PDF in your browser's print window.
Can it write reading passages from scratch?
Yes. Tell Sparky the topic and the reading level, such as "volcanoes for 2nd graders", and it writes a new passage in a document, with the key words defined. Ask for comprehension questions or a second level of the same passage in the same chat.
