Client
Our client is a European EdTech startup in the language learning sector. The company had its own platform with a few thousand students. They turned to Aionys to design and integrate an AI assistant into their platform. The goal was to give students live practice and a comfortable learning experience from day one to results —
40–50% of students are afraid of making mistakes in front of real teachers. They often remain silent and lose valuable practice. Reducing this barrier was a top priority.
Direct interaction with teachers is critical in language learning. But the more complex the language, the higher the price: a Japanese or Turkish philologist costs far more than an English one. For the company, this meant high hiring and operational expenses.
The client already had a working platform with a student base, infrastructure, and familiar interface. A full rebuild would take months, require major investment, and risk losing users who were used to the old format. Instead, AI components were added into the existing environment.
Most platforms don’t provide clear feedback. Students can’t tell whether they’re still at the “ordering coffee” level or already capable of expressing basic needs in conversation. This lack of visibility demotivates and drives churn.
We built an AI-powered learning module that integrates seamlessly into the client’s platform, adding live practice, personalization, and diagnostics without rebuilding the existing product.
Students don’t just see an abstract “bot” — they create their own virtual mentor by choosing gender, appearance, voice, and even personality. As a result, average session time grew by 72%: students stayed longer and practiced more often.
Instead of a dry “right/wrong” response, students see where they stand and what steps lie ahead. Progress is displayed clearly: level, achievements, completed topics. This eliminates the sense of futility and motivates continuous learning.
After the very first session, students receive a roadmap of their level: strengths, gaps, and a personalized plan. This solved one of the platform’s biggest issues — lack of diagnostics. From the start, students know where to focus, instead of working blindly.
Not everyone needs the same approach. We added three modes: learning, supporting, and targeted. Students choose what fits their goals without overpaying.
AI doesn’t just mark mistakes — it supports students at every step. The system analyzes answers, highlights weak spots, and instantly provides explanations with examples and references. This removes the main barrier: the fear of asking “stupid questions.”
The solution runs as a Progressive Web App (PWA). Students launch the platform directly from a browser or mobile, with no installation and no extra server load. This let the client avoid infrastructure rebuild costs and scale the product faster.
Language learning stopped being dry and outdated. With AI avatars and PWA, the platform became scalable and cost-efficient. Here’s what the client achieved:
Thanks to the AI avatar and PWA, students stayed longer, directly increasing the number of paying users.
AI took over part of the workload from teachers at basic levels. This optimized payroll and improved profitability.
Instead of developing a native mobile app, the company launched a PWA. New functionality reached students twice as fast.
We take great pride in the successes of our clients, treating each one as an integral part of our extended family. Their inspiring stories prove the real impact and tangible results of our work.
