☕ How to Choose the Right AI Tool
There is no single best AI tool. The right one depends on what you need to do today.
Try the same prompt in two or three tools. Compare the results. You will notice real differences in tone, accuracy, and usefulness.
Use Perplexity when you need sources and citations. Use ChatGPT or Claude when you need to write or think through a problem. Use Gemini when you are working inside Google tools.
Free tiers are good enough for most people most of the time. Pay for a subscription only when you hit limits that slow your work.
Never share passwords, financial details, medical information, or your children's personal data with any AI tool.
Every AI output is a first draft. Check it with the
READY Framework before you use it.
AI changes fast. A tool that is weak today may improve next month. Revisit your choice every few months.
