Correos Corp. Launches TeacherMatic, a Generative AI Tool Specialising in Education
More than 150 generators help organisations improve the efficiency and productivity of educational operations
Japan, August 2025 – Correos Corp., headquartered in Nakano-ku, Tokyo and led by company president Taro Momose, is a provider of IT solutions for corporate customers. From July 25, 2025, Correos began selling TeacherMatic, an AI toolkit designed for educators provided by Avallain AG, headquartered in St. Gallen, Switzerland and led by its co-founders Ursula Suter and Ignatz Heinz. TeacherMatic is a generative AI tool with more than 150 generators suitable for a wide range of educational scenarios. As a sales partner of TeacherMatic in Japan, Correos will support educational institutions and companies in improving the efficiency and productivity of their educational operations.
Overview and Features of TeacherMatic
Generative AI developed for the education sector streamlines operations, allowing more time to be spent on teaching and ensuring well-being
TeacherMatic is a generative AI toolset developed specifically for education, with over 150 generators to support not only the creation of lesson plans, preparation and evaluation criteria, but also a wide range of educational scenarios and school affairs. Highly accurate teaching resources can be safely obtained and utilised without having to write complex prompts from scratch.
Designed with the input of educators, TeacherMatic has been used by more than 40,000 users at more than 350 institutions worldwide and, even during the pilot phase, has achieved a reduction of 3.8 hours of work per person per week. It is an edtech solution that not only reduces the workload of educators and promotes operational efficiency, but also allows them to spend more time on ‘real education,’ such as interacting with each learner and providing detailed learning support.
More Than 150 Generators Designed for Education Help Streamline and Increase the Productivity of Any Educational Operation
TeacherMatic supports all aspects of educational work, including lesson planning
and preparation, teaching materials, test questions, evaluation criteria, feedback and other educational resources, as well as school work such as preparation for school events and PR activities. It streamlines the educational work of the entire organisation.
Quickly Obtain the Right Product for the Right Purpose by Simply Entering Information in the Form Provided for Each Generator
TeacherMatic’s generators have input forms for setting items that are unique to education, such as class title, learning theme, field of study and target learner conditions, so there is no need to write complex prompts from scratch. By simply selecting a generator that suits your purpose or situation and inputting information, you can easily obtain highly accurate generated results, which can then be exported and utilised in Word, Excel, PDF, or any other format you need. Even in cases where general-purpose generation AI fails to produce the desired results, TeacherMatic can produce effective outcomes.
Strong Security Protects Highly Confidential Data, Making the Convenience of AI Generation Safe and Secure
TeacherMatic, based on Microsoft’s Azure OpenAI, which local governments, the financial industry and large corporations use, complies with strict guidelines such as the EU’s Ethics Guidelines for Trustworthy AI*. Input data is not used to train generative AI, making it safe for use in organisational operations. In addition, unique filtering and checking functions block sensitive information, copyrighted content and discriminatory expressions from being included in the input content and generated results, thus maintaining appropriate use of generative AI throughout the organisation.
Future Initiatives: Supporting the Efficiency of Educational Operations of all Types of Organisations, Including Higher Education Institutions, K12 and Corporations
Correos will propose TeacherMatic to educational institutions, companies, organisations and other organisations that operate educational businesses, helping to solve issues such as reducing the workload of teachers and instructors, ensuring well-being and improving the productivity of the entire organisation. By streamlining the various tasks associated with education through TeacherMatic, we will contribute to the realisation of an environment in which educators can focus on their primary job of teaching.
Terminology
* Ethics Guidelines for Trustworthy AI. The document, published in 2019 by the High-Level Expert Group on AI (AI HLEG), was established by the European Commission and presents the ethical and technical requirements that AI systems must meet in order to be trusted.
