Looking for a FREE 6-Max or 8-Max Tournament Trainer with Instant Mistake Grading

Hi everyone,
I am looking for a completely free poker software tool or website to practice playing against AI bots. I have a very specific setup that I want to practice:

• Table Size: 6-max or 8-max tables (me vs. 5 or 7 bots).
• Game Format: Multi-Table Tournaments (MTT).
• Feedback Style: The tool needs to tell me the exact mistakes I made after every hand or action (grading decisions based on GTO or proper strategy).
• Natural Flow: I want to play full hands from the start (preflop all the way to the river) where the bots act fast, and my position rotates around the table automatically.

I recently tested out GTO Wizard (using their Trainer option set to MTT from start). The interface and live error grading (Inaccuracy / Wrong / Blunder) are exactly what I want, but the 10-hand daily limit on the free tier is just too small to get real practice, and I cannot afford the monthly subscription.
Are there any completely free online tools, open-source software, or downloadable desktop Apps that allow you to play full 6-max or 8-max tournament hands against bots with built-in mistake tracking without any daily hand limits?
Appreciate any recommendations!

I've looked for something similar myself, and honestly I haven't found a completely free tool that does everything GTO Wizard's trainer does. Most free options let you play against bots, but they don't provide street-by-street GTO feedback or mistake grading after every decision.
