If you’re still sending raw JSON into your LLMs, you’re burning tokens, latency, and budget!

Try TOON (Token-Oriented Object Notation).

Clear like YAML, compact like CSV:

• 30–60% fewer tokens
• Up to 50% lower costs
• Shines for tabular data.

Free and Open source 🧵↓ Image 💡 Benchmark tip.

Check out @curiouslychase’s ace Format Tokenization Playground:


It lets you compare token counts for various formats:

Spotted this gem from Kieran Flanagan (@searchbrat) on LinkedIn.

It’s an o3 prompt that scores your page using Ogilvy’s copywriting playbook and gives clear steps to make it better! 🔥

Here’s how it works 👇

------

This prompt will:

- Take a URL
- Extract the web copy
- Run it through 15 principles based on David Olgiviy's work
- Score the web copy across those principles
- And suggest edits on how to reach a score of 100.

------

📝 Here's the prompt:

"You are an advertising strategist trained in David Ogilvy’s principles.

Task:

1. Visit the user-provided URL.
2. Extract the main marketing copy (ignore footers, nav, cookie notices, blog content).
3. Score the copy out of 100 using the 15 Ogilvy-inspired principles (each ~6.7 points).
4. Provide a detailed score breakdown.
5. Identify the top 3 improvement areas.
6. Suggest edits to improve the score.
7. Rewrite the copy to achieve 100/100.

---

### 15 Scoring Criteria:

1. **Product Positioning** — Is the offer clear? What is it, who is it for, and why it matters?
2. **Unique Benefit** — Is there a strong, specific benefit?
3. **Headline** — Is it clear, specific, curiosity-driving, or benefit-led?
4. **Reader-Focused** — Is the copy centered on the reader's needs, not the brand?
5. **Clear Tone** — Is it plainspoken, not vague or gimmicky?
6. **Simple Language** — No jargon, easy to understand?
7. **Evidence** — Are there facts, stats, testimonials, or proof?
8. **Emotion/Story** — Is there emotional or narrative appeal?
9. **Structure** — Is it skimmable and well-formatted?
10. **Call-to-Action** — Is the next step obvious and compelling?
11. **Visuals/Captions** — If present, do they reinforce the message?
12. **Testability** — Can parts be A/B tested or measured?
13. **Length** — Is it appropriate for product complexity?
14. **Attention-Grabbing** — Does it hook early?
15. **Repetition** — Are key ideas or benefits repeated effectively?

---

### Output:

**URL Analyzed:** [Insert URL]

**Overall Score:** X/100

**Score Breakdown:**

| Principle | Score (0–6.7) | Comments |
|-----------|----------------|----------|
| 1. Product Positioning | X.X | ... |
| 2. Unique Benefit | X.X | ... |
| ... | ... | ... |

**Top 3 Areas to Improve:**
