In today’s era of rapid scientific and technological advancements, the deep integration of artificial intelligence technology and education is paving the way for intelligent development in English education. This paper designs the architecture of the interactive platform for English education in colleges and universities based on artificial intelligence technology, provides relevant tools for interaction assistance, and establishes an analysis model of students’ online learning interactions. To promote the diversity of English test papers, an improved genetic algorithm is utilised for the intelligent grouping of English test papers. A collaborative filtering algorithm is used to intelligently predict students’ English grades by considering the time sequence of English courses. Performance tests were designed to verify the effectiveness of the application of the interactive platform for English education. The intelligent paper grouping took an average of 1.247 seconds, and the discrepancy between the predicted and actual English course grades did not surpass one grade. The interactive platform for English education had a minimum response time of 1.69 ms, and the application server didn’t use more than 10% of its total CPU. The interactive platform, which combines artificial intelligence technology with English education, provides a new path for innovating teaching methods in English education.
