PROJECTs by kai
PROJECTs by kai is a central location to find all of Kai Watanabe’s passion projects.
Currently, all projects are Teamfight Tactics related, including (but not limited to) PROJECT PBE, PROJECT MENTR, and Patch Coaching
PROJECT PBE
Set 11 - Set 17
April 4th, 2026 - April 12th, 2026
A competitive pre-season practice tool for Teamfight Tactics, featuring a one-week 3rd-party ranked ladder culminating in a high-stakes, checkmate-style tournament.
Only the top 325 applicants based on peak rank will be accepted for tier 1, and the top 400 applicants after that will be accepted for tier 2. Players who have either attended Worlds or partook in the TPC will auto-qualify for Tier 1.
Sign-ups will open sometime late February/early March. Join the Discord to stay in the know or sign-up for our mailing list below!

Selection is highly competitive.

TFT MATCH REVIEW
Set 16
February 13th, 2026
What if there was a way to get an instant analysis of your TFT game right after you played a game? What if you want access high level guides for a comp you immediately played but don’t know where to find one?
Recently I’ve partnered with Tacter to help develop a Match Review feature within the Tacter app so that you can access fast, high-level analysis right to your phone!
This feature is currently still in Alpha, so let us know what you think by joining the Discord! You can learn more below.
