Why Every PhD Student Needs a Digital Research Toolkit?

Digital tools have universally transformed research today from optional to essential, and in the last decade, a change has occurred in how doctoral research and higher PhD students' work is completed. Researchers today use digital tools to access literature, to organize references, to analyze data, or to collaborate across institutions or time zones.
With the growth of academic publications and the complexity of methods, it is also important to implement an efficient way to organize the task of research.  Digital tools are a great way for PhD candidates to increase efficiency and consistency in their work, whether that's through citations, transcribing interviews, or analyzing statistics.
As universities increasingly respond to and embrace plans for hybrid and remote learning, researchers are increasingly requiring flexibility and mode of action – digital tools will provide the base for this. As technologically cloud-based platforms, collaborative platforms, and even automated research assistants assist at a critical moment like now, they will open up more opportunities for a new wave of research.
If you are a first-time PhD student, integrating the right tools minimizes time but increases the quality of your work and professionalism.
