Source note. What I say about Brisk comes from its own homepage, read in October 2026. It is a fast-moving product, so confirm current details on their site.
What Brisk is
Brisk is a browser extension. Its homepage calls it an AI layer for every tool, website and resource, and the pitch is that it works wherever you are already teaching: a Google Doc, a PDF, a website, a video. The homepage lists 30+ content tools (quiz generator, presentation maker, rubric generator, lesson plan generator), 5+ ways to give feedback on student writing, a tool to change the reading level or translate (it names 50+ languages), 14 student activities built from a text, and a student-facing product it calls Brisk Boost for Students. It offers a free start through its "Get started free" and "Install for free" buttons, and I did not find a dollar price on the pages I read.
What ClassSense is
ClassSense is a web app, not an extension. You upload a PDF, DOCX or PPTX and it builds up to 10 skill packs, each with explanations at three depths, worked examples, named misconceptions, strategy variants and practice items. Students join with a class code and work through the packs. Mastery is tracked per student per skill (at least 5 answers at about 85% accuracy), and the dashboard lists the students who need you. Details are on the AI lesson plan generator page.
The real difference: where the work happens
Brisk meets you in the middle of a task. You are reading an article, you click, and you get a quiz or a differentiated version of that article. It is quick because there is nothing to set up. The output lands in the document you were already in.
ClassSense asks you to set a course up once. That costs a little time on day one and pays back in the weeks after: students practice without you building each set, answers are graded automatically, and the mastery record builds itself. If you only ever need a one-off quiz from a page you are looking at, that setup is overhead you do not need.
Where Brisk is the better choice
- Feedback on writing. Brisk lists several ways to leave feedback on student writing. ClassSense does not grade essays or extended writing at all; student practice is multiple choice.
- No setup. Install it and use it on whatever is open. ClassSense needs a course and an upload first.
- Reading level changes and translation. ClassSense has not been tested in other languages, and I would not rely on it for translation.
- Cost to try. Brisk has a free start. ClassSense has 30 days free, then $19 a month.
Who should not switch
If most of your pain is feedback on student writing, or you want AI help inside Google Docs and slides all day, Brisk fits that better, and ClassSense will add little. Also note that ClassSense reads text. A scanned worksheet whose meaning is in a diagram will extract poorly, and handwriting does not survive upload.
If your pain is that thirty students are at thirty different places and you cannot tell where without grading everything, read formative assessment and then try one unit. Starting with one unit costs you nothing for 30 days and needs no card.
Common questions
Is Brisk free?
As of October 2026, its homepage offers a free start and I did not see a price on the pages I read. Check their site for current plans.
Can ClassSense give feedback on student essays?
No. Student practice in ClassSense is multiple choice. For feedback on writing, a tool built for that is the better choice.
Can I use Brisk and ClassSense together?
Yes. They sit at different points in the week, and nothing about one stops the other.
Does ClassSense work inside Google Docs?
No. It is a separate web app, and you upload a PDF, DOCX or PPTX into it.
