COOLlectif is a Chrome extension designed to analyze polarized online discussions and provide constructive responses to ease tensions. By integrating with popular platforms like Facebook, Twitter, Reddit, and YouTube, it identifies heated comments and employs AI to assess the emotional tone of conversations. Users can select from a range of calming personas to craft their replies, ensuring their contributions are thoughtful and non-confrontational.

The extension features ten unique personas, each offering a different approach to communication, from empathetic responses to humor and fact-checking. COOLlectif requires no registration and does not collect personal data, allowing users to engage freely. This tool is particularly valuable for individuals looking to foster a more positive online environment while avoiding moralizing or judgmental tones.
