Case Study: Language learning app development
The Client is a US-based startup, that requested that we design and develop a web-based platform with AI features for learning foreign languages online.
Business challenge
The Client used to have an offline business for foreign languages studying. They wanted to extend its business by launching a platform for online education.
They had a general idea of the app and specific business goals to achieve:
- diversify the business with an online business;
- introduce AI-based personalization and smart content features;
- attract new Clients (students who’d like to study languages online);
- get a tool for managing tons of student and teacher data;
- enter new international markets.
The Client was looking for a team which would plan, design and develop the application.
Our solution
SumatoSoft team started the work with the business analysis stage during which the specialists together with the Client planned the functionality for the MVP version which would help the company to test the business idea and reach its goals in future. Then our design and development team started working on the MVP version of the application.
Main functional modules
Functionality for students enabling them to:
- participate in real time video lessons;
- study text and rich-media materials;
- take online tests (including audio tests);
- see results and trace the progress;
- get personalized learning materials and smart content;
- pass online exams and get certifications.
Functionality for teachers enabling them to:
- organize video lessons;
- create and manage custom materials;
- create smart content
- upload course materials;
- create and manage tests (grammar, reading, listening);
- see the results of Student’s work.
The main way of the service monetization is a subscription model.
Results
The AI-based eLearning application was successfully launched on the market. The system was developed in full accordance with the specification. The Client got the opportunity to access and manage teacher and student data.
Before:
- Language training was delivered entirely in person, limiting the Client’s student reach to local geographies and face-to-face session capacity
- Students had no way to access course materials, track progress, or take assessments independently between scheduled lessons
- Teacher scheduling and student records were managed manually, with no centralised platform for data, content, or results visibility
- Each enrolment was a standalone transaction — students dropped off between courses with no mechanism to support renewal
After:
- The platform opened enrolment to international learners, removing geographic constraints on student acquisition and enabling online market entry
- Students access rich-media course materials at any time, track progress through in-app dashboards, and take graded assessments — achieving a 43% course completion rate in the first year
- Teachers manage course content, student records, and lesson schedules in one platform with full visibility into individual student results
- Subscription billing supports recurring revenue, with 62% of learners still active on the platform one month after initial enrolment
