Do my students really need a tutor?

2/3 of students can't read grade-level text by the end of high school*

Reading plays an important role in every subject in every grade

Students improve their reading skills by reading difficult text with support

Your students' biggest obstacle to success in your class may actually be their reading comprehension.

Like a good tutor, Structal...

Anticipates student struggles

Based on the latest reading research, Structal highlights areas of the text students might struggle with and provides them with support when they hover over one of the highlights.

Allows students to ask questions

Students can click on any word in what they’re reading to see support, like a definition, translation, or hear the word read aloud.

Works with whatever you teach

Structal is a plugin for your students' Chromebooks (a Chrome Extension) that allows it to work on anything they read with their Chromebook.

Wait, where does it work?

On anything your students read on their Chromebook!


E.g. news articles, online textbooks, your LMS, primary sources


E.g. Canvas, Google Classroom, Schoology, Blackboard


E.g. books, primary sources, labs, worksheets

Google Docs/Slides

E.g. homework, worksheets, other students’ writing

You don't have to change what you teach to use Structal.

Is it really free?

Yes, there will always be a free version of Structal!

Our founder Mike is a former teacher, and he hated getting set up with a product, only to find it has a short trial or usage limits.

We make our money by selling a Plus version to districts.

When you use Structal for free, you help us demonstrate its effectiveness to your district, so your administrators feel confident purchasing our Plus features.

How do I know this will work?

Teacher created

Our founder is a former 6th grade ELA teacher and every feature we’ve built has been in collaboration with the educators currently using Structal in their classroom


Every feature we’ve built is also based on interventions from research studies that demonstrate their effectiveness.

Real results

Last school year, students using Structal showed a 66% growth in their vocabulary and 100% of teachers reported an increase in student confidence.
