Which AI for Which Task?

by Tom McAtee | 4 Aug 2025 | AI in Practice

Don’t get overwhelmed – get intentional.

With so many AI tools out there, it’s easy to feel paralysed:
“Should I use ChatGPT, Claude, Gemini, Grok, or something else?”
“Is this tool better for writing, coding, research… or all of the above?”

Here’s the reframe:
You don’t need to know everything about every model.
You just need to know enough to make a smart choice for the task at hand.

This post gives you a simple way to decide: Match the task to the tool.


1. The Two-Minute Matrix: Tool Selection by Use Case

Task Type AI Model(s) That Shine
Writing & summarising ChatGPT (GPT-4) – great tone control, stable reasoning
Structured analysis Claude – handles large documents with clarity
Google-integrated tasks Gemini (via Workspace) – strong in Gmail, Docs
Real-time, short-form Grok – built for quick insights, X-platform friendly
Coding & logic-heavy GPT-4 (via OpenAI), Claude, or GitHub Copilot
Voice-first interface ChatGPT (Voice Mode) – best for back-and-forth conversation
Long-term project work ChatGPT Projects + Agents – build structured thinking threads

2. Personal Fit Matters

Different people prefer different user interfaces, rhythms, and “personalities”:

    • ChatGPT feels like a calm, reliable colleague

    • Claude feels like a sharp analyst

    • Gemini feels like Google – because it is

    • Grok feels like a punchy commentator

    • Custom GPTs feel like bespoke assistants

Try them all. Then pick 2–3 core tools and go deep.


3. Don’t Confuse Feature Sets with Fluency

The best AI tool is the one you can use fluently.

Yes, Gemini can cite sources. Claude can handle 150K tokens. ChatGPT can build agents.

But those features only matter if they serve your real goal:
Getting unstuck.
Thinking faster.
Writing smarter.
Making better decisions.

Don’t chase features. Chase fit for purpose.


4. What About Paid vs Free?

Here’s the honest take:

    • Free versions are fine for experimentation

    • Paid versions (like ChatGPT Plus) offer the best models, tools, and updates

    • If you’re using AI in serious work — research, consulting, writing, strategy — the upgrade is worth it

Think of it like a bicycle:

    • Free = walking

    • Paid = riding

Both get you there. One just saves time and effort.


Final Thought

The AI landscape will keep shifting. New tools will rise. Interfaces will change.

What won’t change is this:

Smart use of AI isn’t about knowing every tool.
It’s about knowing your work — and choosing the right collaborator.
