Myriad

What is Myriad?

Myriad is a free AI content prompt generator from NamePepper. Rather than typing instructions from scratch, you choose a task, write, rewrite or analyze, then switch on rules covering things like writing style, tone of voice, target audience, SEO keywords, marketing goals and temperature. The tool combines more than 35 rules and over 150 instructions into one ready-to-paste prompt, and you can add rules of your own. Rules can be marked with an exclamation point so the AI treats them as higher priority when instructions conflict. A companion verification prompt asks the AI to explain how its writing met each rule and to report any rules that clashed, which helps you spot skipped instructions and fine-tune the setup. Myriad is tuned for ChatGPT, tested most with ChatGPT Plus, and the vendor ranks Copilot, Gemini, Llama and Claude behind it for following the rules. The page includes worked examples, tips and FAQs, and the tool is labeled free.

How to get started with Myriad

1. Open the tool and pick a task: write, rewrite or analyze.
2. Switch on the rules you need, such as tone, audience, SEO keywords and marketing goal, and add custom ones if required.
3. Copy the generated prompt into ChatGPT or another AI assistant and run it.
4. Paste the follow-up verification prompt to see how each rule was met and fix any conflicts.

Myriad limitations

• It produces prompts only; the writing is done by the AI you paste it into
• Tuned and tested mostly with ChatGPT Plus
• Long rule lists can make an AI skip some rules, so prompts may need splitting
• Custom instructions can take trial and error
