Photorealistic Product Shot (Midjourney)
ImageMidjourney v7
product photography of [PRODUCT], studio white background, soft natural side lighting from left, shallow depth of field, 85mm lens, commercial shoot, high resolution, sharp focus, lifestyle product photography --ar 4:3 --style raw --v 7
Best with: Midjourney v7 with --style raw for less AI processing. Tip: Replace [PRODUCT] with specific description: "ceramic coffee mug with matte black glaze" not just "mug."
Code Review — Senior Engineer
CodingClaude / ChatGPT
Review this code as a senior engineer. Find:
1. Bugs or logic errors
2. Security vulnerabilities (injection, auth issues, data exposure)
3. Performance problems (N+1 queries, unnecessary loops, memory leaks)
4. Readability issues
5. Missing error handling
For each issue: describe it, explain why it's a problem, and show the fix.

Email Thread Summarizer
ProductivityClaude / ChatGPT
Summarize this email thread. Format your response as:
**Decision made:** [one sentence, or "none yet"]

Best with: Claude — precise formatting compliance. Use case: Long threads before a meeting, or catching up after time off.
The best prompts specify a role ("you are a senior engineer"), a task with clear constraints ("review this code for security issues"), and an output format ("respond with a numbered list"). The more specific the output format, the more useful the response.
Which AI is best for writing prompts?
Claude Sonnet 4 is the best for writing, editing, and instruction-following. It produces more natural prose and follows complex style instructions more precisely than GPT-4o. ChatGPT is slightly better for technical writing and math-heavy content.
Do these prompts work with the free versions of AI tools?
Yes — most prompts here work with the free tiers of Claude, ChatGPT, and Perplexity. Image generation prompts require a Midjourney subscription or access to DALL-E 3 via ChatGPT Plus. We label each prompt with the recommended tool and whether it requires a paid plan.
What is prompt engineering?
Prompt engineering is the practice of designing inputs to AI models that produce better, more reliable outputs. The key techniques: role assignment ("you are..."), chain-of-thought prompting ("think step by step"), format specification ("respond as a numbered list"), and few-shot examples (showing the model what good output looks like before asking for it).
Can I use these prompts commercially?
All prompts on this site are free to use for any purpose, personal or commercial. The outputs you generate with any AI tool using these prompts are governed by that tool's terms of service.
