AI has eliminated the struggle of staring at a blank screen, wondering what to write next.

How to Prioritize and Choose the Right Topics

How can you ensure your content makes an impact, helps you grow your business, and positions you as an authority?

How can you stand out without spending countless hours producing repetitive content?

In this post, I’ll share a framework and prompt that will help you create a content plan that drives real results.

90-Day Content Library System

Josh Spector created a framework that's helped him publish over 1,000 pieces in six years, attract more than 40,000 email subscribers, and build a six-figure biz.

By leveraging AI and the 90-Day Content Library System, you can:

  • Generate an endless stream of content ideas tailored specifically to your niche

  • Prioritize topics that establish your authority and showcase your expertise

  • Create timeless, evergreen content that delivers results long after it's published

Who Needs This?

If you’re a coach, consultant, or service-based business owner looking to:

  • Build authority in your niche

  • Save time and energy on content creation

  • Align your content with your offers and audience's goals

Then the 90-Day Content Library System is exactly what you need.

How the 90-Day Content Library System by Josh Spector Works

Here's a quick overview of how Josh’s framework works:

  1. Select a specific audience and identify a goal you want to help them achieve.

  2. Brainstorm a list of 30 tasks or topics your audience needs to complete or understand to achieve their goal.

  3. For each of the 30 tasks or topics, develop three types of content:

    • How-to content that provides step-by-step instructions and tips

    • Why-to content that explains the importance and benefits of the task

    • Examples and case studies that showcase real-life success stories and provide inspiration

  4. Publish one piece of content per day for 90 days, rotating through the three content types for each task or topic.

  5. After 90 days, reshare and repurpose the content, updating and expanding it as necessary.

Now that you understand the basics, let's dive into how you can use AI to streamline, prioritize, and build a timeless content library.

Step 1: Specify Your Audience and Goal

Once you paste the prompt, you’ll be asked two questions:

  1. Who is your target audience?

  2. What goal would you like to help them achieve?

For example:

  • Audience = Coaches/Consultants or Service-Based Business Owners

  • Goal = To create engaging social media visuals that showcase their expertise and attract dream clients, and grow social media following from 0 to 10,000 within 6 months.

Step 2: Execute the 90-Day Content Library Mega-Prompt

Copy and paste the following prompt into your AI tool. In this example, I’m using Claude 3 Opus.

ROLE: You are an expert in content marketing and creating creative content marketing systems.

GOAL: Your task is to create a 90-Day Content Library System and be a user's brainstorming partner. This system is designed to create a recyclable content library targeting a specific audience's needs.

CONTEXT: The process involves understanding the audience and generating a list of 30 tasks to reach their goals, followed by creating three pieces of content for each task - a 'how-to' guide, a 'why' explainer, and a case study.


1. Begin by asking the user who their target audience is and what goal they would like to help them achieve.

2. Once the user provides the target audience and the goal, use your expertise and knowledge to list 30 specific tasks that the target audience needs to do to achieve the identified goal.

3. After listing the 30 tasks, ask the user for feedback. If they're satisfied, proceed to the next step in the checklist (create 'how-to', 'why', and case study content for each task).

4. Ask the user for their preferred approach for the remaining steps. There are two options:

- The Detailed Approach, which involves providing detailed outlines for each piece of content.

- The Type and Title Approach, where you only output the type of content and its title. Follow the user's chosen approach for all subsequent steps.


If the target audience is busy solopreneurs and their goal is to Systemize their content production, some tasks might include:

1. Identify your content pillars and key themes.

2. Understand your audience's needs and content preferences.

3. Define the types of content to produce (blog posts, social media updates, videos, etc.).

For each task, you MUST provide:

- 'How-To' Content: 'How to Identify Your Content Pillars and Key Themes'

- 'Why' Content: 'Why Identifying Your Content Pillars and Key Themes is Crucial'

- Case Study Content: 'How ABC Digital Creator Successfully Identified Their Content Pillars and Key Themes'

For the Detailed Approach, include detailed outlines for each piece of content.

For the Type and Title Approach, only output the type of content and its title.


1. Output the first 10 Tasks for the approach chooses (Detailed or Type and Title)

2. Prompt the user if it's OK to continue with the next 10 and repeat the same until you've finished all 30.


1. The content creation process must cover a period of 90 days, with each day dedicated to a specific piece of content.

2. Each of the 30 tasks should have three corresponding pieces of content: a 'how-to' guide, a 'why' explainer, and a case study.

3. All content should be directly related to the specific audience and their goal.

4. Do NOT skip any tasks or output you provide for any reason.

5. Don't use jargon.

6. No fluffy or flowery language


The output will be in Markdown format.

After you’ve provided the goal and audience, it will generate a list of 30 tasks that will help your audience achieve their goal.

Next, choose between a "Detailed Approach" or a "Type and Title Approach."

The Detailed Approach gives you an outline for each Task, the latter doesn’t.

The AI will output the first 10 tasks and ask if you'd like to continue with the next 10.

Feel free to prompt AI to make edits or adjustments such as:

  • "Make it more about [TOPIC]…"

  • "Don't include [X] or [Y]…"

  • "Include these tools [Insert your tool of choice]…"


Step 3: Review, Organize, and Schedule Your 90-Day Content Library

After running the prompt and generating your list of 90 content pieces, review them for quality.

By following this system, you can ensure that your content production remains consistent and aligned with your audience's needs.

Bonus: Turn Tasks into Engaging Social Media Posts

Turn the list of 30 Tasks and create a 30 day content calendar.

I want you to act as my target audience. And for each Task ask a relevant question that's going through their mind so I can create a social post and answer that 1 specific question and deliver quick value.

For example, if a Task is "Outline Your Automation", a question going through someone's mind could be be: "What is the first step in outlining an automation strategy for my business?".

Prioritize questions that would help them reach the Goal I mentioned earlier and deliver the most value to my audience.

Format the calendar as a table with the columns: Day, Task, Question

Want to test ideas first?

After you’re done with the 90 tasks, then use the prompt above in the same chat window.

The purpose of the prompt is to turn the tasks into a list of questions you can answer like this:

Each task

Now you have a list of 30 questions your audience has on their mind.

Answer each one as a social post.
