Content Calendar	Gemini Flash	Speed

3. Leverage Each AI's Unique Strength

Claude: Ask for analysis, strategy, "why" questionsChatGPT: Ask for creative variations, images, quick contentGemini: Ask for bulk tasks, fast answersPerplexity: Ask for facts, research, sources

Common Mistakes to Avoid

❌ Mistake 1: Using Only One AI for Everything

Wrong:

"I use ChatGPT for all my work."

Right:

"I use Claude for strategy, ChatGPT for images, Perplexity for research."

Why: Each AI is optimized for different tasks. Using the wrong tool wastes time.

❌ Mistake 2: Trusting AI Without Verification

Wrong:

"The AI said it, so it must be true."

Right:

"Let me verify this with a second source / actual data."

Example: We asked Claude to count UI elements it couldn't see. It guessed wrong. Always verify factual claims.

❌ Mistake 3: Not Providing Enough Context

Bad Prompt:

"Write a marketing strategy."

Good Prompt:

"Write a 90-day Meta Ads strategy for a CBSE school in Pune targeting parents aged 25-44. Budget: ₹70K/month. Current cost per lead: ₹832. Goal: Reduce to ₹600-700."

Result: 10x better output with context.

❌ Mistake 4: Accepting First Draft

Wrong:

AI gives answer → Copy-paste → Done

Right:

AI gives answer → Review → Ask for revisions → Refine → Use

Example:

You: "Write a proposal for digital marketing services."
Claude: [Generates draft]
You: "Make it more data-focused, include ROI projections, remove jargon."
Claude: [Much better version]

Q: Which AI is best for beginners?A: Start with free Gemini and free ChatGPT. Both have generous free tiers and are user-friendly.

Q: Is Claude worth $20/month?A: For professionals doing strategic work, absolutely. For casual users, maybe not. Use the free tier first.
