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.

I tried this and found it kind of disappointing. It’s expensive to pay maybe $4 or $5 just for the prompt. It didn’t feel worth it to me. But it was still helpful for getting some design ideas and playing around with the free ones
