The class hub for large lectures

The operating system for large classes.

Hush gives students one place to ask questions, join class discussions, participate, check in, and get course-specific help — while giving instructors a clearer view of what their class needs.

Students join with a class code. No complicated setup.

A course shouldn't live in six different places.

Questions in email, discussion in a group chat nobody can find later, AI in a separate tab that has never seen your slides, and TA hours that can't scale. HUSH puts all of it in one course home — so help is always grounded in the course itself.

Grounded
Answers from this course, not the internet

Course help reads your uploaded slides, readings, and published answers first, and cites what it used. It isn't a generic chatbot pointed at your syllabus.

Private
Real privacy for students

Students can ask anonymously where it matters, private course-help chats are never shown to staff, and HUSH collects the minimum it needs to run your class.

One system
An ecosystem, not another point tool

Questions, chat, rooms, groups, lessons, practice, insights, and notifications all share the same class — so nothing has to be copied between tools.

For students

Never stuck. Never behind. Never alone in the class.

Course Assistant
Help that has actually read your course

Ask anything and get an answer built from your professor's uploaded materials first, then their official answers, with a citation back to the exact slide or page. Every conversation stays private to you.

Learn & practice
Turn confusion into a full lesson

Turn any topic or thread into a guided lesson with worked examples, then test yourself with practice challenges. Deadline reminders pulled from your course keep you on track.

Live questions
Ask without raising your hand

Ask during lecture or any time after — anonymously if your professor allows it. Answers publish to the whole class and stay searchable in the class question bank.

Class chat
The class group chat, kept with the course

Real-time chat with threaded replies, reactions, @mentions, image and file uploads, pinned messages, quick polls, and direct messages between classmates.

Study rooms
Rooms for the exam, the problem set, the project

Students create their own rooms for smaller groups. Come back after a busy week and Catch Me Up summarizes what you missed — clearly labeled as classmate discussion, not instructor guidance.

Notifications
Add HUSH to your home screen

Install HUSH like an app and get real device notifications for replies, @mentions, teacher answers, deadlines, and group assignments. Every alert can be switched off per class.

For teachers and TAs

Answer once. See what's actually confusing. Get hours back.

Answer once
One answer, published everywhere it's needed

Answer the top question and send it to just the students who asked, or publish it to the whole class at once. Everything stays in a searchable question bank until your staff delete it.

Confusion maps
Know exactly what to reteach

HUSH clusters questions, course-help conversations, and practice results into topics, and shows the sticking points ranked by how many students hit them.

Group builder
Split the roster into groups in seconds

Generate random groups or build them by hand, swap students between groups, then publish. HUSH creates a room for every group and notifies each student of their assignment.

Class intelligence
Participation, response time, and usage at a glance

See participation, how fast questions get answered, course-help usage, and top sticking points — per section and rolled up across a department.

Your materials
Upload once, and the course knows it

Slides, PDFs, and docs are indexed so course help can cite them, students can open the exact page, and you can edit titles and descriptions later.

Team notes
A private space for you and your TAs

Leave grading notes, pacing notes, and files for your teaching team. Private to staff, invisible to students.

How it works

Set it up in an afternoon. Use it all term.

01
Create the class

Set up your course section, upload slides and readings, and get a join code.

02
Students join

Students enter the code on their phone or laptop and land in the class home — questions, chat, materials, and course help.

03
The class works together

Ask during lecture or after, get course-grounded help, build lessons and practice, chat and run study rooms.

04
You see what's sticking

Confusion maps and class insights show what to reteach, and one answer reaches everyone who needs it.

Large classes make it easy for quiet students to disappear.

Most students who are lost never say so. HUSH gives them a private way to ask, a place to work with classmates, and help that comes from the course itself — while you finally get to see where the class actually is.

Quiet students get heard

Anonymous questions and private course help lower the cost of admitting you're lost.

Teachers stop guessing

See the topics the class is stuck on before you move on to the next chapter.

Large classes feel smaller

Chat, study rooms, and ready-made groups connect students to each other, not just to you.

Safety first

Built for Safe, Controlled Classrooms

You stay in complete control. HUSH is designed to support your teaching — not replace your classroom policies.

Teacher Approval

Require approval before any question is visible to the class, or let approved-by-default posts flow through. You decide.

Automatic Content Filters

Every submission passes through profanity, harassment, and spam filters. Flagged items sit in a moderation queue for your review.

Flexible Anonymity

Choose one of three modes for your classes: anonymous to everyone, anonymous to classmates but visible to you, or fully identified.

Rate Limiting

A per-class throttle prevents floods of submissions so a burst never drowns out real questions.

Pause Anytime

Turn off new questions across your classes during exams or quiet hours with one switch. Students see a friendly notice.

Chat and rooms are yours to control

Turn class chat, student-created rooms, or direct messages off per class, remove messages or members, and pin what everyone needs.

Moderation Queue

Approve, reject, mark as spam, or delete any question from a single panel — with a running activity log of every action.

You're Always in Control

HUSH is designed to support your teaching — not replace your classroom policies. You decide what students can submit, what gets published, how anonymous participation works, and whether chat and student rooms are on at all.

✔ You control what students see.✔ Automatic filters catch profanity, harassment, and spam.✔ Anonymous participation can be disabled anytime.✔ Private course-help chats are never shown to staff.
