Archetyped is a free Chrome add-on developed by checkmatted that provides actionable information and tendencies about your Lichess opponents during gameplay. It offers valuable insights such as performance rating, game results, speed, and more. The main purpose of Archetyped is to help users make informed decisions about their opponents and potentially avoid players on a hot streak.

Once installed, Archetyped can be pinned to the taskbar for easy access. By clicking on the icon, users can view detailed information about their opponents' current win/loss streak, recent performance rating, usual game speed, frequency of play, level of volatility, and more. The add-on also categorizes opponents into different "archetypes," which are represented by emojis next to their username during gameplay.

The "Archetypes" in Archetyped include "Trending" for players who are performing better or worse than their elo, "In Flow" for those who have won or lost a lot of games recently, "Wild Card" for players who tend to win or lose games they shouldn't, "Devoted" for those who play a ton of chess, and "Speed" for players who are most used to playing bullet, blitz, or rapid games.

Archetyped is a continuously evolving product that is constantly being enhanced based on community feedback. It is free to use and the developers welcome any ideas or suggestions for improvement from users. However, it is important to note that the add-on does not provide any personal contact information for the developers.

Overall, Archetyped is a valuable tool for Lichess players who want to gain insights into their opponents' gameplay tendencies and make informed decisions during their matches.
