Many of us might be familiar with using NotebookLM. For those who do not know it, it is an AI tool which can read your documents (as many as 50 big documents in a notebook), understand it, and answer your questions based solely on the information contained in the documents supplied to it. It is very useful, very easy to use, and is being used by researchers and students.
It can be used as a dictionary reader. The advantage is that unlike Goldendict and other dictionary readers, it can take as input the old dictionaries in pdf (scanned pdf or pdf made from text files). And we know that there are many dictionaries available in this format. Other advantages are that it is free, available from anywhere and any computer connected to the internet. Not only that, it is fast too. It is multilingual and you can ask questions in any language. You can request the answer (output) in a format of your choice (for example, ''give the meaning of the Sanskrit word 'loha' in Hindi''.)
This approach has a bright future too. There are many 'RAG systems' already available for use on local PCs. In the future, better cloud based tools from other vendors may also be available.
To use NotebookLM, you only need a gmail account.
