Meet Myriad

Myriad isn’t another flashy prompt stuffed with extra words that don’t do anything. Each rule and instruction has been crafted and tested to get the best writing from AIs.

Use as many or as few rules as you want. Will you need all of them? Maybe not. Will you be able to build a prompt to get the best content? Absolutely.


Creating content for any use case is a breeze with Myriad. Pick a writing style and tone of voice, create click-worthy titles, add SEO keywords, and even tell the AI to write for specific marketing goals.


Maybe you have old content that needs a refresh. Or you want to write it yourself and then polish it up. No problem! You can use rules to make it more conversational, mimic someone’s writing style, or add a call to action.


Uncover the secret of your competitor’s content or scale your existing content with a consistent brand and voice. And the best part? The detailed analysis gives you a blueprint to use for writing or rewriting tasks.

One scalable prompt. Endless possibilities

Mix and match 35+ rules and 150+ instructions to make prompts in a few clicks for any content, like ads, scripts, articles, webpages, email, and social. You can even create your own custom rules and test them with the verification prompt.

  • Check for conflicts

    Use the follow-up prompt to quickly find out if there are any issues with what the AI wrote. Sometimes AIs skip over a rule because of another conflicting one. If that happens, you can change the instructions or add “!” to the end of a rule label to give it priority over others.

  • Keep it bite-size

    When creating your own instruction for a rule, a couple of words or short sentences usually work best. Using multiple, longer sentences can confuse the AI, causing it to misread or skip over parts of the instruction.

  • Turn up the creativity

    If the AI's writing lacks personality, there are a few things you can do to help.

    • Use the Temperature rule at 0.7 or above.
    • Use the Writing Style rule with the "Creative" instruction or ask it to mimic someone's writing style.
    • Use the Tone rule with instructions like "Playful", "Humorous", or "Irreverent".
    • Use the Colloquial or Slang rule. Some of the writing may be too informal, but you'd be surprised by the creative ideas you can get.
  • Break it down

    AIs can read between the lines but sometimes have trouble with it. For example, if you tell it that your target audience has an income of $50-100K, don’t be surprised if it literally mentions that in the writing. Instead, try translating it into something actionable, like their buying habits.

  • Watch what you ask for

    AIs try really hard to do everything you ask of them. So when you accidentally ask them to do things that conflict with each other, they have to use their best judgment in choosing what to do. For example, if you ask the AI to mimic someone’s writing and also front-load keywords in the article title, it might not front-load the keywords because the person doesn’t write their titles that way.

  • Take it step-by-step

    AIs can lose track of where they’re at and may skip over a few rules if you have a lot of them. If that happens, you can include fewer rules in your first prompt. Then follow that with another prompt with rules to revise the response. Like:

    Okay, that’s a good start, but it needs some work yet. Continue where you left off and use the following rules to rewrite it. Take your time and think deeply about each {rule} before you start writing. Rules marked with ! should be given priority over other ones.


  • Which AIs has Myriad been tested with?

    We’ve tested it the most with ChatGPT Plus, so it’ll work best with it. But you can use it with any text generator or multi-modal AI that has been trained on a large dataset. Each AI has its own quirks and strengths though, so some may read rules differently than others.

    In our testing, here’s how they ranked as far as how well they understand the rules:

    1. ChatGPT
    2. Copilot
    3. Gemini
    4. Llama
    5. Claude

    While ChatGPT is the best all around in writing quality, other AIs can be better at specific tasks. For example, ChatGPT Plus sometimes struggles with analyzing a web page. It does have access to the internet, but can still have trouble getting to the right page or be lazy and claim it can’t do something.

    Try the other AIs if you run into issues like that. In our experience, Copilot and Gemini are more willing to visit and analyze the text of a page for you.

  • Can I use Myriad with AI writing tools and assistants like Writesonic, Jasper, and Rytr?

    We haven't tested Myriad with every text AI, but the prompts will likely work with them as long as the AI is powerful enough. Plus, many of them have built their service on top of ChatGPT or a customized version of it.

  • Can I add my own rules and instructions?

    Yes, that’s what the system is designed for! You can add as many custom rules as you want. Keep in mind that it can take some trial and error to figure out the best instruction to use so that the AI understands.

  • Does the order of the rules matter?

    No, the order doesn’t matter for most of them. However, we did find that some rules like the role the AI should play and the temperature setting work better when they’re listed closer to the beginning.

  • Why isn’t the AI following the rules?

    We tested and optimized the rules, but no system is perfect. And AIs are always being updated and evolving, so what works one day, may not work the same the next. There's also evidence to suggest that AIs can be lazier at certain times of year, which is something we noticed in our testing when using ChatGPT around holidays.

    Here are some things that could be causing the issue:

    • The AI you’re using has limited knowledge of topics or isn’t advanced enough to understand all of the instructions and context.
    • Some of the rules conflict with each other and the AI doesn’t know which ones to prioritize.
    • The AI isn't carefully reading each rule or is "feeling lazy". Using the split response option, which breaks up parts of the writing, often helps.
    • You’re using a temperature setting that’s too high or low. A high temperature makes the AI more creative, but it can also cause it to improvise in ways that you don’t want it to. A low temperature gives you more predictable responses, but the writing tends to be less creative and more generic.
    • The AI can’t read between the lines and doesn’t know how to act on the instructions, so it’s literally mentioning them in the writing.
    • The AI doesn't have the ability to access the internet.
  • Why doesn't the length match what I asked for?

    Some AIs have trouble counting characters and words, surprising as that may be. In fact, the paid version of ChatGPT is better at counting than the free one. We’ve also found that AIs in general are better at counting the number of sentences and paragraphs.

    Here are a few things you can try:

    • Add the Use Case rule instead of or along with the Length rule. A use case gives the AI more context and hints about how it should write, including the typical length and format of that type of content.
    • Use follow-up prompts to ask the AI to revise the writing to fit what you want. AIs are often better at changing the length and reformatting after they've already written something.
    • Experiment with increasing or decreasing the number until you get what you want. Even if an AI doesn't count correctly, it should still generally understand the concept and will write more or less if you change the number.
    • Remove rules that indirectly tell the AI to include more content. If you ask the AI to also include things like anecdotes and facts, it might make it too long.
  • Why doesn't the AI rewrite or analyze the page I provided?

    Sometimes an AI will simply summarize the page and then stop after that. Or they'll claim they're not able to access the internet, even though they should be able to.

    If it claims it can't access the internet, use the text source option instead and paste in the text. If it's able to visit the page but stops before performing the task, just ask it to continue with the task.

  • Can the rules be used with other tasks?

    Yes, AIs should understand the concept of rules for many kinds of tasks. You could even create a whole set of custom rules that have nothing to do with writing. In that case, you'd also want to craft a custom introduction for the prompt that prepares the AI and frames the task for it.
