AI productivity tools cover a surprisingly broad range of tasks.
Some focus on general assistance and writing, while others specialize in research, note-taking, meetings, automation, or scheduling.

For example, a student might use NotebookLM to work with course materials, while a professional could use Zapier to automate repetitive workflows.
This raises an important question: should people use one general AI assistant or several specialized tools?
The answer depends on the workflow, the integrations required, and the type of task.
