Choosing an online class platform: what to look for
When a school, academy or training institute picks a video class tool, what the class needs in order to run comes before picture quality or price: how attendance is recorded, what students must install, how courses and students are managed, and where personal data lives. This guide lists the comparison criteria and then introduces NetServ Education against them, including features it does not have.
Seven criteria, and where NetServ Education stands
| Criterion | What to verify | NetServ Education |
|---|---|---|
| Class features | Attendance, recording and replay, slides and annotation, assignments | Automatic attendance, recording and replay (VOD), PDF slides and annotation, assignments, quizzes (responses and scores are recorded; AI can generate quizzes on the instructor's request) |
| Install burden for students | Do students need an app or an account? | Browser and invite link only; phone browsers supported |
| Course and student management | Per-course materials, notices and rosters; importing existing lists | Per-term course dashboard, smart Excel roster import, student notices (SMS or email), 30-day course trash |
| Privacy and data location | Where student data and recordings stay; anything sent to external AI? | Hosted on NetServ servers; institution-dedicated servers via self-hosting (by arrangement). Server captions use external AI |
| Pricing unit | Per instructor, or per student count? | Per host (instructor) or seat; students are free. Institutions pay per seat per month from 5 seats (volume discounts) |
| Captions and languages | Live captions, captions for recorded lectures, student-facing UI languages | Live captions and translation in 8 languages, multilingual VOD subtitles (.vtt), student UI in Korean, English, Chinese and Vietnamese |
| Recording protection | Can students download and leak recordings? | Students can only watch; ordinary download and right-click save are blocked (screen recording and similar workarounds are not prevented) |
Class features: attendance, recording and materials
Education adds in-app PDF slides, annotation and an instructor face overlay (PiP) to live classes where many students join on camera. Attendance records entry and exit times automatically, with per-session totals and a student-by-session table you can save to Excel. Recording keeps the class screen and audio so absent students can watch later, supports trimming to keep only the parts you need, and offers interim-save intervals as protection against power or server failure. For classes with many students you can also choose a "large broadcast" mode (available depending on server settings).
Student install burden: so connection problems do not eat class time
Connection trouble at the start of class is a common stumbling block in online teaching. In Education, students join with just a browser and an invite link, installing nothing, and phone browsers are supported. Students can enter a class without logging in; they log in to see notices, materials, replays and assignments on the course screen. The Windows desktop app is an optional tool for instructors who want to control a PowerPoint slideshow directly.
Course and student management
Per course, one screen handles the syllabus, notices, materials, weekly plans, assignments, attendance status, bulletin board and student notices. Roster spreadsheets, which differ by school and academy, are imported with automatic header detection and a column-mapping preview, and notices and board posts show who has and has not read them against the roster. Student notices go out by SMS (by email if there is no phone number). Instructors can preview the student view to see what students see.
Privacy and data location
Student information and class recordings are sensitive, so ask first where they stay. The hosted service NetServ operates runs on NetServ servers; two-factor (TOTP) secrets are stored encrypted with AES-256-GCM and off-site backups are encrypted as well. To keep data on school or institution servers, ask about a dedicated-server self-hosting setup (by arrangement). Server captions process the instructor's microphone audio with external speech-recognition and translation AI (Deepgram, Claude), and VOD subtitle translation also uses Claude, so choose with that in mind. Default (free) captions are processed in each browser.
Pricing unit: by instructor, not by student count
Education bills per host (instructor), and students are free. Individuals pay $15 per month for Standard or $30 for Premium (billed annually, about +20% if billed monthly, VAT extra); institutions subscribe per seat (instructor) per month from 5 seats, with the unit price discounted by seat count. There is a free-to-discounted track for education (schools and classes). Server live captions and multilingual VOD subtitles are Premium features. Check with every candidate whether cost stays flat as student numbers grow. See the pricing page for current limits and prices.
When it may not fit
- A full assessment system, such as large-scale exam proctoring or cheating prevention, is central to your classes: check with a demo first that the features you need are there, and if necessary consider a separate assessment tool alongside.
- You must integrate tightly with a school-wide learning management system (LMS): no such integration is in the described feature set.
- Large lectures of thousands are the main use: the large broadcast mode depends on server settings, so ask about size and schedule in advance.
Checklist before you decide
- Can students join from a phone browser with no install or sign-up?
- Is attendance recorded automatically and exportable to Excel?
- Can you import your existing roster spreadsheet as it is?
- Have you checked recording retention, what students can do with recordings, and how far leak protection goes?
- Can you explain to the school and parents which servers hold student data and recordings, and whether external AI is used?
- Is pricing per instructor or per student, and have you converted it to a per-term cost?
- If you have international students, are captions and UI languages sufficient?
Frequently asked questions
Do students have to install anything?
No. Students join with a browser such as Chrome or Edge and an invite link, and phone browsers are supported. The desktop app is for instructors who control PowerPoint directly.
Do students have to pay?
No. The billing unit is the host (instructor) and students (participants) are free. Institutions subscribe per seat (from 5 seats) with volume discounts, and there is a free-to-discounted track for education (schools and classes).
How is attendance recorded?
Entry and exit times are recorded automatically; you can review per-session totals and a student-by-session table and save them to Excel.
Is there a quiz feature?
Yes. Instructors can run quizzes, and students' responses and scores are kept in the course record; on the instructor's request, AI can also generate quizzes from the lesson content (external AI is used for this and is described in the Privacy Policy). If a full assessment system, such as large-scale exam proctoring or cheating prevention, is central to your classes, check with a demo first that the features you need are there.
Where are student data and recordings kept?
The hosted service NetServ operates runs on NetServ servers. To keep them on school or institution servers, ask about a dedicated self-hosted server (by arrangement). With server captions on, the instructor's audio is processed by external speech-recognition and translation AI; default browser captions are processed in each browser.
