Decision Guide

How to Choose the Right AI Tool

You do not need to compare every feature. Start with these four questions.

1

Where Does Your Work Already Happen?

Google-heavy workflow? Consider Gemini. Microsoft-heavy workflow? Copilot may fit naturally. Working mostly with your own source material? NotebookLM may be useful.

2

Do You Need Current Information?

Choose an assistant with web research capabilities and verify important information against the original sources.

3

Is the Task General or Specialist?

Writing an email is a general task. Managing an entire coding repository, SEO campaign or automated sales workflow is a specialist task.

4

How Important Is Accuracy?

For health, financial, legal, academic, compliance or important business decisions, verify AI-generated information independently.
