Common questions
Can I use a skill on multiple platforms?
Yes. The Universal Prompt format works on any AI platform — ChatGPT, Gemini, Perplexity, Claude, and more. The Claude Skill format is specific to Claude Code and Claude Projects.
Do I need a subscription to use skills?
You need an account on whichever AI platform you use (Claude, ChatGPT, or Gemini). Their free tiers work for basic usage; paid plans give you more output length and faster responses.
What if the skill doesn't work as expected?
Skills depend on the underlying AI model. If output isn't what you expected, try rephrasing your input or adding more context. Contact us at contact@zenailab.com and we'll help.
Can I edit the skill after downloading?
Yes — the file is plain text. You can customise the tone, output format, or constraints directly. Think of it as a starting point you own.
