| 32% | increase in completion of study plans |
Project scope
The Aristek team relied on subject matter expertise in AI-based development, the R&D department’s innovative approach, and experience in the EdTech domain. The project included the following steps:
1. Discovery phase
We conducted stakeholder interviews (Product, Education, Support departments) to map learner journeys across 5 popular certification tracks and define success metrics (e.g., pass rate uplift, ticket volume drop, upsell conversion).
Next, we performed a data audit (checking their consistency, the number of missing values, diversity), and validated the client’s ideas in terms of their feasibility with the current data.
2. Development
The development phase included building an AI readiness scoring model, which was previously trained on success/fail patterns, mock test results, activity logs, and other clients data. Also designing personalized guidance engines with study plans, practice targets, and exam countdowns.
3. Integration
Next, we embedded the AI assistant into the client’s eLearning platform (LMS). The backend team leveraged Python-based microservices on AWS Lambda for scalable performance. API integrations included inline support, nudges, reminders, progress tracking, and certification status systems.
4. Testing & launch
In this phase, we piloted 300 real learners from PMP and AWS cohorts, collected UX and results data, and iterated it on tone, frequency, and feedback logic. Then enabled an A/B test of AI-coached vs. control group prep results.
How AI coach works
Learners select a target certification and input their personal learning context. For example, their jobs, responsibilities, previous experience, career goals, learning preferences, etc.
The real-time readiness score tracks learners’ progress and predicts pass likelihood.
Then, the AI coach creates a personalized prep plan, which includes skill gap breakdowns, practice exam recommendations, study focus zones per week, micro-guidance, and more.
Next, it syncs with the platform calendar and sends nudges based on time left for task completion.
In general, the AI coach provides ongoing guidance and monitors learners’ engagement to ensure successful certification prep.
