I’m stuck on 2x + 3 = 11. Where do I start?

Let’s isolate the part with x. Which operation would undo the +3? Remember to do the same thing to both sides.

The question isn’t whether students will use AI.

It’s what they’ll
learn along the way.

Getting an answer is easy. Building understanding takes practice. AI can make it tempting to skip that work—or give a student another explanation, another question, and another chance to improve.

Nexus is built around that second possibility. Students get support to keep going. Teachers define what productive AI use looks like in their classroom.

One platform. A clear purpose.

Support the thinking.
Make room for progress.

Good questions

Let’s make
the details clear.

Visit the help center

Does Nexus do students’ homework for them?

Nexus is designed for guided learning. Teachers can set instructions that steer students toward hints, practice and explanations. AI can still make mistakes or respond imperfectly; classroom expectations and teacher review remain part of the process.

What can teachers see?

Authorized teachers can review prompts and answers in their assigned school classes. Personal accounts and chats outside that school context are not part of classroom review.

Who chooses the AI models?

Your school controls which models students can access. Where multiple responses are enabled, they are options to consider—not proof that an answer is correct.

How is AI usage billed?

Schools connect their own provider account. The provider bills model usage directly, separate from Nexus’s $20 per active student monthly platform price. Budgets and model access can be set by the school.

Can I use Nexus without a school?

Yes. Personal access is available separately at l.narb.cc, with its own account context and usage limits. To join a school, follow your school’s invitation or access process.
