One platform connecting teachers and students, an all-in-one fix for the three biggest pain points of everyday teaching

Pain point 01

Heavy grading workload

Grading an entire class's essays and exercises by hand, one by one, drains huge amounts of teachers' time and energy every week.

Pain point 02

Lagging learning feedback

Students often wait days to get work back, missing the prime moment to correct mistakes on the spot.

Pain point 03

Hard to address individual differences

In a large-class setting, teachers struggle to give every student consistent, targeted guidance.

Summary

In this writing assessment, students generally grasped the requirements of descriptive and expressive writing, developing their pieces around the theme and weaving what they saw and heard together with life lessons and emotion. They frequently employed devices such as metaphor and personification, reflecting their powers of observation and association toward everyday things. The highest-scoring pieces tightly bound the object described to genuine feeling.

Testimonials

AI teaching is an important component of our school’s three-year plan. We have always hoped to provide students with a self-directed learning model, as they have teacher guidance on campus but may lack support at home. Our goal is for the AI system to become a mini-teacher that students can turn to for help at any time. We also hope to cultivate a correct attitude toward AI, helping students understand it is not just for completing homework, but for solving difficult problems to make future learning more ideal. Before choosing UnaGPT, I had been looking forward to an AI software that could integrate all teaching functions. Currently, UnaGPT is the most complete one, and after repeated trials by several teachers, we finally decided to adopt it.

Initially, we were looking for an AI system that could specifically bolster our language curriculum. After a semester of rigorous evaluation, we chose UnaGPT. The greatest challenge was the cultural shift of integrating AI into the campus; naturally, teachers were skeptical about the accuracy and reliability of AI-generated feedback. However, through deep collaboration and bespoke fine-tuning with the Una team to meet our school’s specific needs, that skepticism has vanished. Even after just a few months of implementation, there has been a remarkable surge in teacher confidence regarding the system’s utility and precision.

The true strength of UnaGPT lies in its seamless integration across all academic disciplines. Historically, educational tools have been fragmented—requiring separate platforms for mathematics, languages, and other subjects. UnaGPT breaks these silos by consolidating everything into a single, unified system. Beyond integration, it excels at automating labor-intensive tasks, significantly reducing the administrative burden on educators. Furthermore, Una’s comprehensive training programs ensure that teachers feel empowered and confident rather than intimidated by this new technology.

The standout feature of UnaGPT is its ability to provide highly targeted feedback. For instance, if a specific sentence in a student's essay needs improvement, the system offers precise guidance tailored solely to that issue. This level of accuracy offers far greater practical value than the broad, generic advice typically provided by other AI platforms.

I choose UnaGPT because I have a lot of confidence in the system's privacy and data security. The support from the Una team for schools is very important, as teachers need time to adjust to new systems. What attracts me most about UnaGPT is that it is a single platform suitable for all subjects. Once students become familiar with one system, they won't need to learn another, making it easier for teachers to adapt. This also simplifies technical support within the school, making operations more efficient and smoother. UnaGPT can save teachers time in lesson planning, data analysis, and addressing individual differences. Thus, teachers can interact more with students and better understand their needs.

Even in small class settings, teachers must manage at least ten to twenty students, making it impossible to attend to each one adequately. AI could be helpful in providing a more personalized learning experience.

UnaGPT provides students with instant feedback, helping teachers quickly identify learning challenges and assisting students in personalized learning. The platform not only saves teachers' time on grading but, more importantly, enhances the efficiency of students' writing practice by offering specific and meaningful feedback. This enables students to understand areas for improvement and optimize their content, effectively strengthening their autonomous learning abilities.

UnaGPT is a tool that helps teachers evaluate students’ performance and enables students to self-learn. It is easy to use and can be utilized across multiple subjects.

I find that the Una team has strong research and development capabilities. Once they understood our various needs in the mathematics subject, they developed numerous customized solutions for schools, enabling us to utilize the platform in daily classes to facilitate teaching.
