Prezento AI Coach is a Chrome extension designed to support users in improving their presentation and communication skills through AI-driven feedback. This personal coaching tool offers two primary modes: Free Play and Mission Mode. In Free Play, users can set their own themes and receive objective feedback from AI, simulating interactions with different personas like investors or interviewers. This flexibility allows for tailored practice sessions that cater to specific audiences.

Mission Mode challenges users with concrete scenarios, such as obtaining project approval from an AI supervisor, within a set time limit. After practice, users can review detailed reports via a web application, tracking their performance and competing on a leaderboard with others. Utilizing advanced AI technologies, Prezento AI Coach provides comprehensive evaluations of users' speaking styles, including tone, pace, and visual presentation, making it an effective tool for identifying strengths and areas for improvement.
