ChatGPT is undoubtedly the most popular AI tool out there. Developed by OpenAI, it offers many features. It can write content, summarize documents, help you code, and much more. While the AI is available on the website, there is also a dedicated Windows app for easy access to the tool.
The free version offers fast, almost accurate, and good-enough results for everyday tasks. You can further upgrade to its premium versions for additional usage and capabilities.
3] Claude

Claude is another popular AI tool developed by Anthropic, and it is quickly becoming a favorite among many users. It is known as one of the best AI tools for content writing. Plus, you can use it for other tasks like coding, summarizing long documents, and answering detailed questions.
While you can access it via a browser, it also comes with a free desktop app for a faster, distraction-free experience. The free plan gives you access to Claude Sonnet, which is fast and highly capable for everyday tasks. However, you can upgrade to a premium plan to access additional models.
4] Cursor AI

Cursor AI is one of the best AI tools for developers. If you are into coding, this tool should be your best friend. Cursor AI is an AI-powered code editor built for developers. It looks and feels like VS Code and comes with powerful AI features built right into the editor. You can write code, fix bugs, or ask questions about your codebase using plain English.
Plus, it helps you save a lot of time in your day-to-day coding. Also, the free plan is good enough for most individual developers and students. And just like any other AI tool, you can always upgrade to a premium plan.
5] Perplexity AI

Perplexity is an AI-powered search engine that gives you direct answers instead of a list of links. It is a conversational version of Google. You can ask your questions, and it collects information from the internet and presents the information in an article format. Plus, you can check all the sources to verify everything.
This tool is particularly useful for research, staying up to date on current topics, and getting quick factual answers. The free plan works very well for daily use, and you can access it via both a browser and the dedicated Windows app.
These free AI tools can make everyday tasks faster and easier on Windows 11 and 10. However, they are designed to assist you, not do everything for you, so the best results still depend on your ideas, judgment, and creativity.
