Wrtn rewrites the next generation of its consumer-enabling superapp with Azure OpenAI Service

South Korean startup Wrtn Technologies is transforming everyday life with its AI "superapp," designed to enhance productivity, entertainment, and emotional connections.

By localizing advanced AI technologies, Wrtn empowers users to create their own AI and offers a developer-focused studio tool for building applications.

Using Microsoft’s Azure OpenAI Service and its newest o1 models, Wrtn has scaled rapidly, addressed complex regulatory challenges, and enhanced their product with new innovations to meet the demands of its user base, now topping 5.4M monthly users.

Scaling a "superapp" securely, effectively, and efficiently

At its core, Wrtn's flagship technology compiles an array of AI use cases and services, but localized for Korean users to integrate AI into their everyday lives—bringing “AGI close to people,” is their maxim.

“We mainly focus on three domains of productivity, a mixture of AI search, chat, and tools and templates,” says Dongjae "DJ" Lee, Chief Product Officer of Wrtn Technologies.

The platform fuses elements of AI-driven search, chat functionality, and customizable templates, empowering users to interact seamlessly with an "Emotional Companion" AI-infused agent.

These AI agents have engaging, lifelike personalities, interacting in conversation with their creators. Their vision is a highly interactive "personal agent for everybody, unique and specific to you, your data, and memories," says Lee.

Wrtn's earliest generations of their tools have been wildly popular across South Korea—now used by 5.4 million Korean users monthly—creating new challenges of scale: meeting expanding user demands and adapting and evolving to cultural and linguistic localizations. Among the most important tasks is ensuring compliance to strict regulatory protocols in place across the region—for both its existing consumer-focused product and a newer developer-oriented "Studio Pro" tool.

Embracing Azure OpenAI Service and powerful new o1 models

As demand and scale has grown exponentially and quickly, Wrtn has evolved from working directly with a range of generative APIs to reliance on the o1 models integrated into Azure OpenAI Service with Azure AI Foundry. A huge advantage for Wrtn’s evolution is Azure’s native integration with the newest o1 models, with their advanced reasoning, logic, and multi-step problem solving capabilities.

Azure’s robust framework gives Wrtn with the foundations they need to grow and enhance their consumer and developer products: enterprise-grade security, regional data residency, and unparalleled support for regulatory compliance—essential features for a company navigating legal requirements across South Korea.

"One of the most important things Azure OpenAI Service provides is keeping data in the region," says Lee. Azure's regional offices and servers around the world keep the data protected and localized. "The bigger our traffic grows, the more important Azure's enterprise-level service enhancements are to us,” he adds.

Azure AI Content Safety is a critical component for Wrtn, providing built-in ability to toggle elements like content filters and prompt shields for different end users. This lets its developers scale its products while staying compliant, customizable, and responsive to users across different regions across Korea.

“It's not just about the security and privacy, but also safety. Through Azure, we can easily activate or deactivate content filters. It just has so many features that add to our product performance,” says Lee.

“Azure’s seamless integration is one of the key enablers of our agent workflows and multi-action agents,” says Lee. The o1 model has also excelled in handling intricate queries requiring advanced reasoning capabilities. Wrtn’s users could pose complex logical problems, and the AI would generate precise and reliable answers.

“The success rate of accurate answers to queries has grown exponentially in the o1 models, according to our measures,” says Lee.

Wrtn also leveraged the o1 model to develop AI-powered tools that could translate user prompts into fully functional code. This feature not only democratized coding for a broader audience but also empowered Wrtn's internal developers in generating high-quality code quickly and accurately.

Users could now input natural language descriptions of problems and receive comprehensive coding solutions, enhancing both accessibility and efficiency.

This capability unlocked new use cases for Wrtn, from solving advanced mathematical problems to providing nuanced insights into multifaceted challenges.

"There’s a lot of enterprise support that other model providers lack at this point. Microsoft really adds that value on top of the APIs," says Lee.

Advanced reasoning, generating products with rich roadmaps and possibilities

The impact of the Azure OpenAI Service o1 model on Wrtn’s operations has been transformative.

On the customer-facing side, the introduction of coding tools powered by the o1 model led to a significant surge in user engagement. Wrtn saw a sharp increase in the daily usage of coding features, underscoring the demand for accessible, high-quality AI solutions.

The company also observed measurable improvements in the accuracy and reliability of responses to complex queries, along with increased responsiveness and speed for end users.

Internally, the adoption of the o1 model streamlined Wrtn’s development processes—generating valuable operational ROI. Developers used the model to accelerate project timelines, leveraging its advanced reasoning capabilities to address challenges more efficiently. "To people who want to have the most advanced logical thinking process engraved into their models, we would definitely recommend the o1 model integration with Azure OpenAI Service,” says Lee.

Looking ahead, Wrtn plans to scale its offerings by blending foundation models for everyday tasks with heavy-duty models like o1 for specialized use cases.

This dual impact of the o1 models available in Azure—improved user experiences and heightened internal productivity—has transformed Wrtn's ability to scale its products and meet ROI objectives.

Azure is a huge help in achieving their ambition. “Wrtn’s aiming to become a local champion in the AI era, just like in the mobile and internet eras,” says Lee.
