Excellent tool. Especially their chrome extension and context feature that makes it so I never need to repeat myself when jumping between LLMs. It upgrades my prompts instantly right inside any LLM chat tool. Super worth the monthly sub, unlimited prompt generation and unlimited prompt saving AND unlimited contexts.

@The Prompt Challenge

Great way to improve you prompting skills through daily exercises. This should be implemented in schools, would really help students. Can also see it being really valuable for adults. Not just for prompting, but for articulation in general. Also made a video about it: https://www.youtube.com/watch?v=A8ZRJgLCFy8
