Claude, ChatGPT, Gemini, Copilot: Which One Should You Actually Use?

If you are new to AI, do not waste weeks trying to compare all the tools. This is what each AI tool is actually for in most 9-5 jobs, where it falls short, and the first task worth trying today.

Stick to one platform, ideally the one your IT department has already approved.

If you have more flexibility at work, then pick one platform to master based on its capabilities. After that step, then you can choose the platform for each specific task.

Claude: The sharp writer and designer

The best for nuanced thinking, this is the colleague you hand a messy draft to and get back something clear and well thought through.

Claude is best-in-class for writing materials that sound like a person wrote them.

Claude is also best for UX, brand identity design and coding websites, thanks to its connector to Figma, where you can turn production code into editable designs.

If you're more technically-inclined, you can create custom workflows, dashboards or web apps with Claude Code.

What this looks like in a real workday:

• Paste a 40-page document and ask: "What are the three things in here that could pose as risks later in the project?"

• Hand it your rambling bullet notes and get a status update an executive will actually read (without sounding like "It's not X, it's Y."

• Give it 5 customer complaint emails and ask what pattern connects them

• Upload last quarter's report and say "write this quarter's in the same structure"

• Creating a website mockup for a new landing page

• Ingesting local files on your computer into a dashboard via Claude Code

Where it's weak: no image generation. Fewer integrations into other apps than ChatGPT.

First task to try: paste your longest unread work document and ask for a summary with 3 callouts of risks.

ChatGPT: The Office Swiss Army Knife

The coworker who can do a bit of everything: text, images, voice conversations, web research, quick charts.

While it's not the deepest at any single thing, it has the widest toolbox — especially helpful for image generation. ChatGPT also has a popular coding assistant, Codex.

What this looks like in a real workday:

• Make a quick image for a slide or a mockup of a living room renovation

• Talk to it on your commute: rehearse a salary conversation or a difficult feedback session out loud

• "Research our top 3 competitors' pricing pages and put the differences in a table"

• Drop in a CSV export and ask for a chart of monthly trends

Where it's weak: writing outputs sound like AI and have more shallow strategic thinking. Quality varies more between tasks.

First task to try: use voice mode to prep for your next meeting

Gemini: The one who lives in Google Suite

Gemini lives inside the Google ecosystem: Gmail, Docs, Sheets, and Drive.

Its superpower is that it can already see your work files without you uploading anything.

What this looks like in a real workday:

• In Gmail: "read my emails and tell me what follow-ups I owe to whom"

• In Docs: highlight a section and ask it to tighten the wording — without leaving the doc into another chat

• In Sheets: "which rows shows a decline in [insert metric]?"

• In Drive: "find the deck where we discussed the Q3 pricing change"

• In Meet: automatic meeting notes with action items, saved to Drive

Where it's weak: outside Google's apps, it's a middle-of-the-pack chatbot. The value is the integration.

First task to try: open your longest, most vague email thread and ask Gemini to summarize it and draft the reply.

Copilot: The one that works with Microsoft

Same idea as Gemini, Microsoft edition: built into Outlook, Teams, Word, Excel, and PowerPoint.

This is the tool your IT department is most likely to have approved, which, at a big company, decides the question for you.

What this looks like in a real workday:

• In Outlook: "draft a reply agreeing to the timeline but flagging the budget risk"

• In Teams: join a meeting late and ask "what did I miss?" — it recaps the conversation live

• In Excel: "add a column showing % change and highlight anything below target"

• In PowerPoint: "turn this Word doc into a 10-slide deck" — then fix the design, but the skeleton's done

• In Word: first drafts of proposals pulled from your existing files

Where it's weak: same as Gemini, the standalone chat is unremarkable. And results in Excel/PowerPoint often need cleanup. It is my preferred platform to create LinkedIn infographics.

First task to try: ask Copilot in Teams to recap a meeting you skipped.
