Coolest I've seen? Honestly, I'd put one I worked on myself into the mix — it's called WFGY.

It’s a prompt + PDF system that helps large language models repair reasoning in real-time. We’ve seen improvements like: • Semantic Accuracy ↑ 22.4% • Reasoning Success ↑ 42.1% • Stability ↑ 3.6×

No installs. Just feed the AI a file and use a new style of prompt. GitHub: https://github.com/onestardao/WFGY
