Diffit vs. Brisk Teaching: Choosing an AI Tool for Classroom Workflows

Choosing between Diffit and Brisk Teaching comes down to where you want AI to fit into your teaching workflow. Diffit is built around preparing and adapting classroom resources. Brisk covers more of the work around those resources, including lesson planning, student feedback and teacher-directed AI activities. Both can adjust reading levels, translate materials and turn existing content into instructional resources, so a longer feature list alone won’t settle the choice.

My read is that Diffit is the more focused option for teachers who repeatedly need accessible versions of materials and ready-to-use activities. Brisk looks like a better fit when those tasks sit alongside assessment, feedback and digital student practice. The classroom examples below are possible uses, not reports of hands-on testing.

Two different starting points

Diffit’s central workflow starts with a topic or source material and ends with resources a teacher can edit, print or export. Brisk starts from a broader set of teaching tasks and works through a browser extension or a web-based workspace. That difference shapes how each tool fits into lesson preparation.

Feature access can depend on the plan, and the comparison reflects the providers’ current product and pricing information. Teachers should check the specific plan details for tools they expect to use.

Diffit: from source material to differentiated resources

Diffit accepts pasted text, PDFs, URLs, video transcripts and prompts describing a topic or need. With Diffit Chat, teachers can request adjustments such as a different reading level, a translation, a revised activity or a teacher guide. The workflow is aimed at turning source content into material that can be used in class. Diffit

That focus reaches beyond rewriting passages. Teachers can create differentiated activities, station materials, intervention resources and slides, then print or use supported exports depending on their subscription. For someone preparing several entry points into the same lesson, that concentration on resource production is the appeal.

Take a science lesson on ecosystems. A teacher could use a source article to prepare a version with more accessible language, add vocabulary support and pair it with a structured activity. The lesson can keep the same central concepts while offering students different levels of support.

Here’s the thing: reading level is only one measure of a useful adaptation. If the rewritten material removes key vocabulary or makes the relationships between ideas less clear, students may lose the very content the lesson is meant to teach. Teachers still need to review accuracy, essential concepts and the level of challenge.

Brisk: a wider set of teaching tasks

Brisk Teaching supports lesson and assessment creation, content adaptation, translation and feedback on student work. Its browser extension brings tools into familiar digital environments, while its web workspace provides another place to work with teaching materials.

Feedback is one of Brisk’s clearest distinctions from Diffit. Options include Glow & Grow, Next Steps and Rubric Criteria feedback. Teachers can review and edit the output before sharing it, while some features, including targeted comments in Google Docs, require premium access.

For a persuasive-writing assignment, a teacher might use Brisk to draft comments against a rubric. The review step matters: feedback should help students improve the skill being taught without doing the thinking for them. If the goal is selecting relevant evidence, for example, comments that supply the evidence could undercut the practice students need.

Brisk’s breadth may suit teachers who want one set of tools to help with preparation and with reviewing student work. That breadth also means the best fit depends on which functions are available under the plan a teacher or school uses.

Where student AI use changes the decision

Diffit is designed for teacher preparation. Students can work with the resources it produces without having to interact with an AI system. That can fit classrooms where AI supports the teacher’s preparation and students do their learning through reading, discussion, writing or practical work.

Brisk adds student-facing activities through Brisk Boost. Teachers can create experiences for tutoring, debate, writing coaching and inquiry, then set objectives and guardrails, preview the activity and share it with students. Monitoring tools give teachers visibility into student activity.

That option brings a different planning question into the classroom: what should students attempt on their own, and where should AI provide support? The activity design should make those expectations clear before students begin.

Pricing and access

Diffit has a free Basic plan that includes resource creation, editing, printing and PDF downloads. Its individual paid subscription is listed at US$14.99 per month or US$149.99 per year, though prices can vary by country. Paid features include additional export options, alignment options, graphic organizers and access to the full history of created resources. School and district licenses are also available.

Brisk offers a free teacher plan, plus Premium and Intelligence plans for schools and districts with custom pricing. According to its help centre, free-plan usage limits can vary with traffic. Check current plan terms before relying on a particular feature or expected usage level.

Which tool fits your workflow?

For teachers who regularly need differentiated passages, scaffolds and printable activities, Diffit is the more direct match. Its design centers on adapting content and producing classroom resources. Brisk looks better suited to a workflow that spans planning, adaptation, feedback and guided student AI activities.

Some teachers may find value in both if resource creation and feedback are separate recurring needs. The useful comparison is practical: try the same lesson with each free plan and look at factual accuracy, the quality of the scaffolds and how much editing the output needs before students can use it. The tool that fits is the one that supports the learning goal while keeping review manageable.

The distinction is likely to remain useful as teachers choose classroom AI: start with the task that comes up most often, then judge each tool by the quality of the materials and decisions it helps you prepare.
