The Challenge

Learnly had 45,000 registered students using a third-party LMS (TalentLMS) that offered no personalisation, no Hindi content support, no offline capability, and charged per-student pricing that made unit economics unsustainable at scale. Course completion rates were 12% — typical for e-learning but unacceptable for a product competing on learning outcomes.

Our Solution

Canny built a custom LMS with AI-adaptive content sequencing, vernacular language support (Hindi, Tamil, Telugu), Progressive Web App offline mode, and a live tutoring module. The platform replaced TalentLMS and reduced per-student infrastructure cost by 65% while improving course completion to 58%.

Technical Architecture

Next.js frontend (PWA with service worker for offline)

Node.js API server on AWS Lambda (serverless for cost efficiency at scale)

PostgreSQL for student and course data, Redis for session and progress cache

AWS S3 + CloudFront for video streaming with adaptive bitrate (HLS)

OpenAI API (GPT-4o) for adaptive quiz generation and learning path recommendations

AWS Translate + Bhashini API for Hindi/Tamil/Telugu content

“The completion rate jump from 12% to 58% is the single metric our investors track. The AI adaptive sequencing is why students finish courses they would have abandoned before. We couldn't have built this on any off-the-shelf LMS.”

— Deepa Menon, CEO — Learnly

Long-Term Impact & ROI

Learnly grew from 45,000 to 200,000 students in 8 months post-launch, raised a ₹18 crore Series A, and launched a B2B school licensing product built on the same platform. The offline PWA capability opened rural Tier 3 and Tier 4 markets that were previously inaccessible.
