ZisuGen – The Digital Empire for Modern Tutors
SoftGen's flagship SaaS — the platform that's quietly reshaping Sri Lanka's Rs. 200B private education industry. Military-grade DRM, AI-powered grading, and smart attendance for 10,000+ students. Built by us. Owned by us.
Transforming Disconnected Workflows Into a Unified Digital Engine
ZisuGen isn't a client project — it's SoftGen's own bet on the future of education. We identified a massive gap in Sri Lanka's private tuition industry: educators earning Rs. 5M+ monthly were losing 40% of that to video piracy, drowning in manual grading, and managing 3,000+ students with Excel sheets. ZisuGen is our answer — a vertically integrated B2B SaaS platform that gives every tutor the technological firepower of a billion-dollar EdTech company, at a fraction of the cost.
Key Architectural Takeaways
Addressing Real Operational Bottlenecks
How SoftGen dissected operational friction and engineered a high-concurrency cloud solution.
The Operational Challenge
Legacy Workflow Deficiencies
Sri Lanka's top private tutors collectively serve 2M+ students and generate an estimated Rs. 200B annually — yet they operate with the technology stack of a 2005 internet cafe. The three critical pain points we identified: (1) Rampant video piracy via screen recording, costing individual tutors Rs. 500K–2M monthly in lost revenue. (2) Manual attendance check-in queues of 1,000+ students creating 45-minute delays at physical class entrances. (3) Paper grading consuming 20+ hours weekly for tutors with 3,000+ students, making personalized feedback physically impossible.
- ✕Fragmented learning materials spread across email, messaging apps, and static drives
- ✕Zero telemetry into whether trainees completed reading assignments or practice tests
- ✕Reliance on third-party video call subscriptions with no native LMS attendance tracking
Our Engineered Solution
Custom Cloud Architecture
SoftGen's engineering thesis was radical: what if we could give a single tutor the same digital infrastructure as Coursera or Udemy, but designed specifically for Sri Lanka's hybrid (physical + online) tuition model? We built ZisuGen on three pillars: (1) A proprietary browser-level DRM system that intercepts screen capture at the OS layer — not with flimsy watermarks, but with actual rendering pipeline manipulation. (2) A multi-agent AI grading system powered by Gemini and Groq that grades structured papers with 94% accuracy against human benchmarks. (3) A QR-based attendance gateway that processes 1,000 students in 8 minutes with automatic parent SMS confirmations.
- Unified portal with role-isolated dashboards for Admins, Trainers, and Trainees
- Interactive assessment engine with automatic grading, rubrics, and feedback loops
- Embedded LiveKit WebRTC video meetings avoiding external software overhead completely
End-to-End Operational Lifecycle
How training assets, evaluations, and real-time sessions flow securely through the system.
Identity & RBAC
Row-level access rules separating Admins, Trainers, and Trainee permission scopes.
Secure Courseware
DRM-protected PDF viewer and centralized video library with zero download leakage.
Evaluation Engine
Randomized quizzes, manual exercise rubrics, and automated grading pipelines.
WebRTC Classroom
Low-latency virtual rooms powered by LiveKit Cloud with waiting-room moderation.
Real-Time Telemetry
Continuous trainee scoring, attendance metrics, and automated administrative reporting.
Modular Systems Built for Scale
Each module was architected to replace friction-heavy manual processes with automated software workflows.
Zero-Piracy DRM Engine
Our proprietary browser-level protection intercepts screen capture at the rendering pipeline — not with detectable overlays, but with actual frame-level manipulation. Screen recording software captures blank frames. Casting is blocked at the protocol level. This isn't DRM theater; it's military-grade content protection.
Multi-Agent AI Grader
A specialized Gemini-powered grading pipeline that decomposes structured exam papers into individual question agents. Each agent grades independently against curriculum-aligned rubrics, then a meta-agent validates consistency. Achieves 94% accuracy vs. human grading at 200x the speed.
QR Attendance Gateway
High-throughput QR scanning system designed for physical class entrances. Processes 1,000+ students in under 8 minutes with instant parent SMS/WhatsApp confirmation. Eliminates manual roll-calls and the notorious 'proxy attendance' problem entirely.
White-Label Edge Architecture
Each tutor gets a custom subdomain (tutor.zisugen.com) routed through Cloudflare Workers with edge-cached assets. This means a tutor in Matara and one in Jaffna both get sub-200ms load times without us deploying separate infrastructure.
Modern, Scalable Enterprise Stack
Carefully chosen frameworks and cloud infrastructure for extreme velocity, security, and low latency.
Measurable Operational Impact
Concrete performance metrics and organizational improvements verified in live production.
Audited Performance
10,000+ Active Students & Tutors onboarded within 4 months of launch
Zero Content Piracy Incidents — not a single successful screen capture recorded
60% Reduction in Administrative Overhead — tutors report saving 15+ hours per week
Rs. 0.14/hr Cost-per-Student — making us 12x more cost-efficient than competing platforms
“ZisuGen is a revolution. The DRM protection alone saved our institute millions in lost revenue, and the AI features allow our tutors to focus on teaching rather than grading.”
