3 Things You Must Know Before Using Free AI Tools

Just because it is free does not mean there are no limitations. To properly master how to use AI, it is essential to know the following three things.

There are usage limits

Most free AI tools have limits on daily or monthly usage. It is more efficient to combine multiple tools according to your needs rather than relying on just one.

You must be careful when entering personal information

Content entered into the AI may be stored on the server. As a general rule, you should never enter sensitive personal information such as resident registration numbers, passwords, or financial information. Even when using it for work, it is advisable to check your company's policy in advance regarding the entry of confidential information.

Free policies can change at any time

Features currently free may later become paid. This article is based on information as of April 2026, and it is recommended to check the latest policies of each tool directly on their official websites.

The combination of ChatGPT, Canva AI, and DeepL is the most suitable. You can experience all three basic functions—conversation, images, and translation—for free.
