Proof of learning, in every subject.
Know what your students actually know.
Nexus shows teachers how homework was actually done, whether students can explain it, and where their class is struggling. In every subject.
The problem
A finished answer does not tell the whole story.

lower test scores for students who practiced with an AI that gave them answers, once the AI was taken away. Their practice scores had risen 48%.

Three approaches leave the same gap.
Ban AI

Detectors guess from the final text. They do not show how the work was made.
Read every chat
A chat history only shows what happened in that tool. It does not show homework made elsewhere.
Three steps
How the Work check works
See how the work was made
Replay the writing sessions, pasted blocks and rewrites. See the evidence behind each label.
Hear it in their words
Explain your work asks 3 short questions after turning in. Optional: the teacher turns it on or off.
Talk with the right students
Use Steady drafting, Worth a look or Talk with student to guide a conversation. Labels, never scores.
One class. The evidence that matters.
See each student’s label and the evidence behind it. Open the replay, then decide who needs a conversation.
Every school gets its own Nexus
Every school gets its own Nexus: its own name and logo, sign-in, rules, approved AI models and help levels, and only the modules it chooses.
Work check
Start with the Work check alone: replay, labels and optional Explain your work.
Study assistant · optional
Hints, not answers, at the help level the teacher sets. Student chats are not shown to teachers.
AI basics · in development
We’re building short lessons on using AI well, with completion tracking. Your school chooses which modules to enable.
Student privacy, with clear boundaries
The Work check records writing only in assignments the student linked, only on the school’s approved sites, only while the on-screen “recording” label shows. It never records other browsing, passwords, or anything outside linked assignments.
Student chats are not shown to teachers.
School AI calls are routed with provider data collection denied, and student work is not used to train AI models.
Works with what you already use
Canvas, Google Classroom, Microsoft Teams and Blackbaud. Word for the web, including OneDrive, SharePoint and Teams assignments. Students and teachers use their school accounts: Microsoft 365 or Google. Students turn work in where they always do.
Google Docs is not supported by the extension yet.
Questions schools ask before they begin.
Is Nexus an AI detector?
No. Detectors guess from the final text; Nexus shows how the work was made. Signals start a conversation; they are not proof.
Do students need a new account or a new place to turn in work?
No. Students use their school’s Microsoft 365 or Google account and turn work in where they always do. The Work check uses an Edge or Chrome extension on supported platforms.
What does the extension record?
The Work check records writing only in assignments the student linked, only on the school’s approved sites, only while the on-screen “recording” label shows. It never records other browsing, passwords, or anything outside linked assignments.
Can teachers turn Explain your work off?
Yes. Explain your work is optional. The teacher turns it on or off. When enabled, students answer 3 short questions about their own work after turning in.
Does it work in every subject?
Yes. The Work check shows how written work was made in every subject, on supported platforms. It is not limited to essays.
Can we use only the Work check?
Yes. Every other module is optional and enabled per school. Your school chooses what to turn on.
Does it work with Google Docs?
Google Docs isn't supported by the extension yet. For now, students write in Word for the web or on their school's platform.
Who is Nexus for?
Nexus is for schools. For students under 13, the school authorizes use for its own educational purpose, parents get a notice, and the under-13 controls stay on.
How does Nexus support learning?
The Work check shows how homework was made and can ask students to explain it. The optional Study assistant gives hints, not answers, at the help level the teacher sets.
What can teachers see?
Teachers see Work check labels and the evidence behind them, and where the class struggles. Student chats are not shown to teachers.
Which AI models can students use?
The models the school approves, under its own rules and help levels.
How do you handle student data?
School AI calls are routed with provider data collection denied, and student work is not used to train AI models. The Work check records writing only in assignments the student linked, only on the school’s approved sites, only while the on-screen “recording” label shows. It never records other browsing, passwords, or anything outside linked assignments.
Is Nexus for school or personal use?
Nexus is for schools. Every school gets its own Nexus, with its own sign-in, rules and choice of modules.
How does pricing work?
Start with a free pilot in one teacher’s class, for about 6 weeks. After that, one school-wide annual license covers everything the school turns on, with a 30-day opt-out. Pricing is arranged with the Nexus team.

What’s next: early screening
1 in 5 children in the U.S. have learning and attention issues, but only a small subset are formally identified with a disability in school (NCLD, 2017). We’re developing a short check schools run with parent consent, where a specialist always decides.
