Choosing AI Assistants & Productivity tools
General-purpose AI assistants answer questions, draft and summarise text, help plan work and, increasingly, read files, browse the web or run small tasks for you. They are often the first AI tool people try, and the one they use most days.
Because they cover so much ground, the differences between them are easy to miss. Some are strongest at long documents, some at reasoning or coding, some at working inside the apps you already use. The right choice depends less on which is "best" and more on the work you do every week.
A practical way to choose is to try two or three assistants on the same real task, such as summarising a document you know well, and compare the results. Check any facts an assistant gives you before relying on them, especially numbers, names and dates.
Who it is for
Anyone who writes, researches, plans or answers questions as part of their day: students, freelancers, office teams and managers.
What to compare
- What the free plan allows, and what the paid plan adds
- Whether it can read your files, images or web pages
- Where it runs: web, desktop, mobile, or inside tools you already use
- How your data is handled, and whether team or business plans exist
- Whether an API is offered if you want to build on it
Common uses
- Drafting emails, reports and replies
- Summarising long documents or meetings
- Brainstorming and planning projects
- Explaining unfamiliar topics step by step
