NotebookLM

NotebookLM is Google’s document-based AI tool. It is famous for its ability to answer based on only your own data and turn the data into a podcast conversation.

This is a document-based AI tool created by Google, and the key is to answer based only on the data you upload. If you upload a PDF, web link, video, etc., it creates not only a summary and Q&A, but also podcast-style audio of a conversation between two hosts.

It is especially useful for researchers and students who need to read papers and reports, and office workers who need to organize large amounts of data. You can start for free, so there is no burden.

Unlike regular chatbots, the advantage is that the basis is limited to your own data, reducing incorrect information, but it cannot answer questions outside the scope of the uploaded data.

✅ Strengths

• There is a low risk of incorrect information as answers are based only on my own data
• The source is indicated on the answer, making it easy to check the original text
• The audio function that turns the data into a podcast conversation is unique
• You can use the core functions for free

⚠️ Limits

• It is vulnerable to questions outside the scope of the uploaded data
• If the data itself is inaccurate, the answer will also be inaccurate
• When uploading a sensitive document, you must check the security policy
