Best Free AI Tools: What Are They and Key Features

Artificial intelligence is rapidly becoming a part of everyday life and is being applied in various areas such as education, business, commerce, and daily tasks. However, not all users are willing to pay to use AI tools. This is not a problem, since there are free AI tools with excellent capabilities and wide functionality: from analyzing PDF files to personal assistants. This article will teach you the best free AI tools and their features.

What are AI Tools?

AI tools are software solutions based on artificial intelligence. They are software, services, and platforms that use the capabilities and functions of neural networks, machine learning, and other algorithms. The main function is to help people perform various types of tasks, such as text generation, document analysis, helping with studies, processing video and audio content, working with images, etc.

AI platforms are used to automate processes and simplify interaction with information. Today, such tools are becoming more accessible, and many are open completely free of charge. You don’t need to register or install any programs — just use them directly in your browser

Notebook LM

This is the best free AI, although it is still experimental. This is a project from Google. The AI tool is designed to work with text and text notes. Users can upload data and then ask questions based on these materials.

Among the main features of this AI tool are:

• extraction of key ideas and theses;
• structuring information in a report format;
• personal AI assistant for notes.

For example, if you downloaded a package of lectures on mechanics, you can ask: What is the operating principle of a 4-stroke engine based on notes? As a result, you will receive a structured, accurate, and tailored answer.

For many, this is the best AI solution due to the advantages:

• free access;
• support for various formats;
• intuitive interface.

However, it is important to consider that Notebook LM is not available in all countries, and localization is limited. The interface, like the answers, is mainly only in English.

Ask AI Questions

Among the best and free AI tools online, many users rightly highlight this solution. This is a simple but highly effective tool for asking AI questions. Registration to use the service is not required. It works in the format of an online platform, where everything is collected in one place. Your task is to ask a question, to which you will receive an instant answer.

Ask AI Questions stands out from other AI tools due to several features and advantages:

• relevance for studies and everyday tasks;
• free use;
• instant access;
• no advertising;
• work with complex and technical queries.

You can easily get a detailed and understandable answer to complex questions. For example, how to explain the principles of quantum mechanics to a student, or write a detailed essay on the topic "The role of the French army in World War II".

An additional advantage is the simple and intuitive interface. There is a field for entering a request and a button to get an answer. If you need a service to ask an AI a question quickly, this is rightfully one of the top AI tools.

AIPDFReader

A real salvation for those users who regularly work with large PDF documents. This AI solution can download and interact with files like a chatbot. With this AIPDFReader tool, you can:

• get the main point from large files;

Students have found wide applications for working with textbooks, scientific articles, and training materials. Lawyers actively use the product to analyze contracts and check agreements. Even marketers use the AI platform to quickly review industry reports.

An important advantage of the tool is that everything works through the browser. You do not need to download or install anything before starting work. This saves you a lot of time, and you can easily understand the document without reading it in detail and in full.

Notion Q&A

Among the popular and effective AI programs, this solution is definitely worth highlighting. Notion is a universal knowledge base, personal Wiki, and task management system. And now an AI assistant has been built in. It simplifies and speeds up work with notes. You will be able to:

• ask questions about the content;
• find information by meaning and keys;
• get detailed explanations;

An important advantage is the integration into the Notion environment, as well as high search efficiency and access through free accounts. Just keep in mind that the platform only works in English.
