Stop Losing Your Best Prompts: How to Build an Automated Prompt Library in Notion

The ‘Goldfish Memory’ Problem: Where Prompt Engineering Dies

You spend an hour crafting the perfect prompt. You iterate through 15 variations, testing tone, structure, and examples. Finally, you get exactly what you need—a prompt that generates CEO-level executive summaries with the right balance of brevity and insight.

You use it. It works perfectly. You close the tab.

Two weeks later, you need that prompt again. You can’t remember the exact wording. You try to recreate it. You spend another hour. You get close, but not quite right. The magic is gone.

For prompt engineers, this isn’t just frustrating—it’s why you keep reinventing the wheel. Your browser extension should build a reusable prompt arsenal, not force you to start from scratch every time.

The ‘Prompt + Output’ Pair: Why Context Matters

Saving prompts in a text file doesn’t work. You need proof that the prompt works—the actual output it generated.

The Wrong Way: Prompt-Only Storage

Title: Executive Summary Generator
Prompt: "Summarize this in executive style..."

Six months later, you find this prompt. Questions arise:

• What model did this work with? (GPT-4? Claude?)
• What was the actual output quality?
• What input did you test it on?
• Why did you rate this as “good”? Without the output, you can’t validate the prompt. You have to test it again to see if it still works.

The Right Way: Prompt + Output + Context

Title: Executive Summary Generator (CEO Tone)

Prompt:

You are a Fortune 500 CEO's chief of staff. Summarize the following report in executive style:

Requirements:
- Maximum 3 bullet points
- Lead with business impact, not technical details
- Use active voice, avoid jargon
- Include one actionable recommendation

Report:
[Input text]

Test Input: [The actual report you used for testing]

Output:

• Revenue opportunity: $2.3M ARR from enterprise segment if we ship SSO by Q2
• Risk: 3 enterprise deals blocked on this feature; competitors already have it
• Recommendation: Prioritize SSO over new analytics features in Q1 roadmap

Metadata:

• Model: GPT-4
• Date: 2026-01-07
• Rating: ⭐⭐⭐⭐⭐
• Use Case: Board reports, investor updates
• Tags: #Writing #Executive #Business Now when you find this prompt, you have complete context. You know it works, how it works, and when to use it.
