Prompts that actually work

Claude is one of the strongest AI assistants for coding — especially for larger codebases, debugging, and code review. These prompts are tested to get the best results from Claude 3.5 Sonnet and Claude 3 Opus for software development tasks.

ChatGPT is a powerful tool for personal finance planning, budgeting, investment research, and financial literacy. These prompts help you think through financial decisions, build budgets, and understand complex topics — all tested on GPT-4o. Note: ChatGPT is not a licensed financial advisor and these prompts are for educational and planning purposes only.

Claude excels at structured financial analysis, scenario modeling, and breaking down complex financial concepts. These prompts are built for personal budgeting, retirement planning, debt payoff strategies, and investment education — tested on Claude 3.5 Sonnet and Claude 3 Opus. Claude is not a licensed financial advisor; use these prompts for research and planning only.

Gemini brings strong multimodal and data analysis capabilities to personal finance tasks. These prompts are designed for budgeting spreadsheets, tax preparation research, financial comparison tables, and investment education — tested on Gemini 2.0. Gemini is not a licensed financial advisor; these prompts are for educational and planning purposes only.

Grok is ideal for financial research that depends on real-time data — market trends, economic news, and fast-moving financial topics. These prompts are optimized for Grok 3 and take advantage of its live data access for stock research, market analysis, and economic trend tracking. Grok is not a licensed financial advisor; use these prompts for informational purposes only.

Microsoft Copilot integrates directly with Excel, Outlook, and Microsoft 365 — making it uniquely useful for hands-on financial tasks like budget spreadsheets, expense tracking, and financial email drafting. These prompts are built for everyday money management inside the tools you already use. Copilot is not a licensed financial advisor; use these prompts for planning and organization only.

Agents can now hold wallets, make payments and act across connected services, and the standards for proving they were authorised are still being written. These six prompts are for the audit you should do before enabling any of that: what your agents can already reach, what happens when one is manipulated, and what evidence exists afterwards. Written for Claude but they work in any assistant.

With the official DALL-E GPT retired on 30 August, ChatGPT Images is now the default for a lot of people who never chose it. These six are built around the failures that waste the most attempts: text that comes out garbled, styles that drift between images, compositions that ignore what you asked for, and the specific problem of getting the same character twice. They work in ChatGPT Images, Midjourney and Gemini with minor wording changes.

Every major AI security incident this year reduced to the same thing: untrusted input reaching something that executes. The Snowflake workflow injection put issue titles into a CI run block. The Ray CVE left an endpoint that runs code guarded by a header string anyone can spoof. Forcepoint hid instructions in white-on-white zero-size email text that reached the model but not the reader. These six prompts point a model at those specific patterns rather than asking it to find bugs in general.

On 8 August ChatGPT Search began scoping queries to named domains, and Reddit lost 86 percent of its citation share within days. Citation position behaves like a live ranking signal that can be re-weighted overnight, not like a backlink profile. These six prompts are for checking where you stand, run them across ChatGPT, Gemini, Claude and Perplexity and compare the answers rather than trusting one.
