On July 24, 2026, Claude's new model "Opus 5" was released. Putting aside the technical jargon, I'll tell you what this means in one sentence.
For a $20/month Pro plan, you can now use a world-class brain.
Until recently, the "world's strongest" Claude Fable 5 became standard equipment for the Max plan, which costs $100+ per month. On the Pro plan, you could only use it via pay-as-you-go. "I can't pay that much," I thought, and I wasn't alone. Then, four days later, Opus 5 appeared. With intelligence rivaling Fable 5—and even surpassing it in "thinking tasks"—it is available directly on the Pro plan. No extra charge. Just switch the model on your screen.
So, what do you do with this ultimate brain? My answer is clear: Hire your own exclusive "Life Strategy Consultant."
The process is simple. Pass your personal information stored in Gemini Notebook (formerly NotebookLM) to Opus 5 and:
- ① Have it create a roadmap to your dreams
- ② Have it design numerical targets (KPIs) to measure progress
- ③ Have it accompany you through weekly reviews
I established this "Trilogy" during the Fable 5 era and received a huge response. For those who skipped it because "Max is too expensive," I have reorganized it into a single guide that you can run for $20 a month. All you need is Claude Pro and the free Gemini Notebook. The operations are just copy-pasting and chatting. No programming or difficult settings. Let's begin.
Chapter 1: Understanding Opus 5 and "Role Division" in 3 Minutes
Before the main part, please keep this in mind. It takes 3 minutes.
Opus 5 in three lines:
- ① Achieves intelligence close to the top-tier Fable 5 at half the price.
- ② Ranked top in the world for "thinking tasks" like analysis, strategy, and writing, surpassing Fable 5.
- ③ The new standard for the Max plan and the strongest model available on the Pro plan.
One symbolic example: According to the announcement, in a task to restore 3D data of mechanical parts from a single image, Opus 5 created the necessary tools (image analysis mechanism) itself to complete the task. Other latest AIs couldn't solve it under the same conditions. We are moving from "AI that does what it's told" to "AI that prepares what's missing and thinks ahead." We will use this "thinking power" for our own lives.
Role Division: Notebook "Stores," Opus 5 "Thinks"
One more thing: the division of labor between the two AIs.
Gemini Notebook is the "Vessel of Knowledge" that stores materials and retrieves them accurately. It's a place of trust that answers based only on your information with citations. However, it runs on a lightweight model focused on speed. While sufficient for answering faithfully to materials, thinking through life strategies several steps ahead is not its role.
Therefore, we divide the work. Store knowledge in Notebook. Let Opus 5 do the thinking. Output information from the notebook → Paste it into Opus 5 to think → Return the results to the notebook for storage. This cycle is the core of the Trilogy.
Chapter 2: STEP 1—Provide Your Info to Create a "Life Strategy Document"
The first step is to tell Opus 5 everything about you and create a Strategy Document (Life Strategy Document) to achieve your dreams.
Preparation: Prepare a "Self-Note" (10 minutes)
The material is your Self-Note in Gemini Notebook—a collection of your strengths, weaknesses, values, experiences, and goals. If you already have one, use it. If not, you can make one today. Open a recording app on your phone and talk about yourself for 10 minutes. Your successes, regrets, what you're good at, and what you truly want to become. No need to speak perfectly. Just upload the audio file to the notebook (Gemini Notebook can read audio directly).
Step ①: Have the notebook output "Everything About Me"
Open your Self-Note and enter this prompt:
I will have Claude Opus 5 think about my life strategy after this. Please output all my information (strengths, weaknesses, values, experiences, goals, reflections) in this notebook without summarizing. No suggestions or advice needed. Do not omit specific episodes, numbers, or emotional descriptions.
The key is "without summarizing." If information is diluted here, the strategy will be weak. Copy the entire long text that comes out.
Step ②: Paste into Opus 5 and create the document through dialogue (Core Part 1)
Open Claude and select Opus 5. Paste this prompt along with the "Everything About Me" you just copied.
You are my exclusive life strategy consultant. Below is "Everything About Me" that I have accumulated in Gemini Notebook. Please read this and work with me through dialogue to create a "Life Strategy Document."
[Rules] - Generalizations are prohibited. Always base your writing on my information, citing it like "From your description of..." - Do not sugarcoat. Provide painful observations paired with countermeasures. - Do not output everything at once. Output one part at a time, add 1-2 questions for me at the end of each part, and wait for my response before proceeding.
[Structure of the Life Strategy Document] Part 1: Analysis of Me (Extract strengths, weaknesses, and core values from records) Part 2: Gap between Dreams and Reality (Organize what is missing based on facts) Part 3: Three Strategic Options (Design 3 routes to the dream and recommend one with reasons) Part 4: 12-Month Roadmap (Monthly goals and countermeasures for months where I might stumble) Part 5: Failure Rehearsal (Assume failure one year from now, identify causes, and plan prevention) Part 6: Weekly Rhythm (Design a weekly template for action on weekdays and reflection on weekends)
After Part 6, output the "Life Strategy Document: Complete Version" reflecting all dialogue. This is an important asset for my Gemini Notebook, so write it to your full potential without omissions.
Let's start with Part 1.
(Paste "Everything About Me" here)
The trick is not to let it create everything at once, but to proceed part by part through dialogue. The AI will ask questions at the end of each part; you just answer. With each answer, the strategy deepens to fit you. This takes about 2 hours. Do it on a weekend morning with a cup of coffee.
Step ③: Save the completed strategy document to the notebook
Once you finish Part 6, the "Life Strategy Document: Complete Version" will be output. Copy the full text and save it as a note in your Self-Note, then add it to the sources. Now, the strategy conceived by the strongest brain is an asset in your notebook. Chats disappear, but what you return to the notebook remains. Think with Opus 5, save in Gemini Notebook.
Chapter 3: STEP 2—Design "Numerical Targets" to Measure Progress
You have a map (strategy). Next, you need a meter to measure if you are moving correctly. The biggest reason dreams fade isn't a lack of motivation, but losing track of progress. In this chapter, Opus 5 will create your dedicated numerical targets (KPI Dashboard).
Why you shouldn't decide numerical targets yourself
Because if you decide, you will either be too easy on yourself or overextend. On unmotivated days, you'll pick easy goals. You'll hit the numbers every week, but won't get closer to your dream. Conversely, on motivated nights, you'll set unrealistic goals like "3 hours every day!" and fail within two weeks.
Therefore, it's best to have an emotionless third party calculate backward from the goal. No one is better suited for this than a world-class "thinking AI."
"KPI Dashboard" Prompt (Core Part 2)
Paste this prompt and the Life Strategy Document: Complete Version into Opus 5.
You are a professional numerical target (KPI) designer with no emotions. Below is my "Life Strategy Document." Read this and work with me through dialogue to create a "KPI Dashboard" to measure my progress weekly.
[Rules] - Determine numbers based only on backward calculation from the goal and my track record in the strategy document, not my "feeling" of what I can do. - Even if I want easy numbers, reject them with evidence. - Output one part at a time and wait for my response.
[KPI Dashboard Structure] Part 1: Quantifying the Final Goal (Define the dream as "Deadline + Measurable Number") Part 2: Backward Calculation (Final Goal → Monthly Goals → 3-5 Weekly Actions) Part 3: Slackness Check (Inspect if targets are too easy, just wishful thinking, or irrelevant to the dream) Part 4: Translation to Action (Specify "Which day, what, how much" for weekly actions and set a "Minimum Line" for bad weeks) Part 5: Weekly Review Promise (In this chat, when I send "Weekly numbers + a comment," return: ① Achievement status ② Reasons for success ③ Causes of stumbling ④ Advice for next week. Focus on fixing the system, not blaming.)
After Part 5, output the "KPI Dashboard: Complete Version."
Let's start with Part 1.
(Paste "Life Strategy Document: Complete Version" here)
Save the completed "KPI Dashboard: Complete Version" to Gemini Notebook. You now have both the map and the meter.
Chapter 4: STEP 3—Run Weekly with a "Reflection Note"
Honestly, if you don't do this, the previous two won't work. The meter only moves when data flows in. Create a Reflection Note to get into a weekly rhythm.
All you need are two files: a Document and a Spreadsheet
Add two sources to your Gemini Notebook:
- Google Doc for Reflection: A place to write a few lines of reflection every weekend.
- Google Sheet for Records: A place to enter the KPI numbers. Columns: "Date / Results for each goal / Short memo."
The reason for using Google Docs and Sheets is that when you update the original file, Gemini Notebook automatically updates to the latest version.
Weekly: Just send numbers to the Opus 5 chat
On Sunday night, enter your numbers in the sheet and send the same content to the Opus 5 chat from STEP 2.
"This week: 2 articles (Goal 2), 3 meeting prep (Goal 3), 4 hours study (Goal 5). Study didn't go well."
You'll get an analysis like: "You always achieve your article goal when you create the outline on Tuesday morning. This is your winning pattern. The study failure isn't a matter of will; every time meeting prep exceeds 3, study time is cut. Try fixing '30 mins study the morning after meeting prep' next week."
Monthly: Have the notebook analyze the month collectively
Once a month, look at the accumulated records. Use Gemini to read the reflection note and ask:
Read all sources and analyze my month. Cite numbers and descriptions to answer: 1. At this pace, will I reach the 12-month goal? 2. What is my "winning pattern" common to good weeks? 3. What is the biggest cause holding me back? 4. Suggest 3 new improvements for next month in order of recommendation. 5. Is the trend upward or downward compared to last month?
Chapter 5: Fable vs. Opus—The Conclusion for Pro Users
For Pro Plan ($20/month) users:
No need to hesitate. Run everything on Opus 5. It is the optimal choice for knowledge work.
For Max Plan ($100+/month) users:
Use Opus 5 daily and save Fable 5 for "heavyweight strikes" like major career shifts or total strategy overhauls.
For Free Plan users:
If you want to do this, upgrade to Pro. $20 is too cheap for hiring a strategy consultant, KPI designer, and weekly reviewer.
Summary: The Trilogy is now a $20 Daily Reality
Claude Opus 5 provides intelligence close to Fable 5 at half the price. Store knowledge in Gemini Notebook, think with Opus 5.
- STEP 1: Create a Life Strategy Document
- STEP 2: Design a KPI Dashboard
- STEP 3: Rotate the cycle with a Reflection Note
This Sunday, secure 2 hours and try STEP 1. The moment you read the first output where the world's top brain unearths your strengths, the meaning of your $20/month will change. Dreams are no longer just for wishing; they are for driving. The steering wheel is already in your plan.
