Artificial intelligence is no longer something that only concerns software developers and big technology companies. For ordinary workers, AI tools are increasingly becoming useful for writing emails, preparing presentations, researching information and handling repetitive tasks.

But with hundreds of AI tools now available, the bigger question is: which ones are actually useful at work?

Here are five AI tools worth knowing about and what you can realistically use them for.

1. ChatGPT — Your General-Purpose AI Assistant

ChatGPT is probably the easiest place to start because it can handle a wide range of everyday tasks.

You can use it to draft emails, summarise long documents, brainstorm ideas, rewrite complicated information in simpler language or help organise your thoughts before starting a project.

For example, instead of spending 20 minutes trying to write a professional email, you can give ChatGPT the important details and ask it to turn them into a clear message.

It can also help with spreadsheets, reports, presentations and even computer code.

The important thing, however, is not to blindly copy everything it produces. AI can make mistakes, particularly when dealing with facts or specialised information.

Best for: Writing, brainstorming, summarising and general office work.

2. Perplexity — For Research

Researching something online can quickly turn into a rabbit hole of opening dozens of websites and trying to work out which information you can trust.

Perplexity takes a different approach. You can ask it a question in normal language and it searches the web and provides an answer with sources.

For someone preparing a report or researching a business topic, this can be a useful starting point.

For example, instead of searching Google for “South Africa AI market 2026” and opening multiple results, you could ask Perplexity to explain the current market and provide sources for the information.

But it should not replace checking the original sources. AI search tools can still misunderstand information or cite sources incorrectly.

Best for: Initial research, finding sources and getting an overview of unfamiliar topics.

3. Gamma — Creating Presentations

Creating a PowerPoint presentation from scratch can be surprisingly time-consuming.

Gamma allows users to describe what they want to present and uses AI to generate a presentation.

For example, you could enter:

“Create a 10-slide presentation explaining how social media can help a small business attract customers.”

The tool can generate the structure, text and visual layout.

You will still need to review and edit the presentation, but the biggest advantage is that you don't have to start with a blank slide.

Best for: Presentations, proposals and quickly turning an idea into a visual document.

4. Canva AI — Creating Visual Content

You don't have to be a graphic designer to create professional-looking social media posts anymore.

Canva's AI features can help users generate designs, images and written content from simple instructions.

A small business owner, for example, could use it to create a promotional poster for a weekend sale without hiring a designer for every social media post.

The results still need human judgement. AI-generated designs can sometimes contain awkward text, poor layouts or images that don't accurately represent the product.

But for simple marketing material, it can significantly reduce the amount of time needed to produce something usable.

Best for: Posters, social media graphics, presentations and marketing material.

5. Notion AI — Organising Your Work

One of the less obvious uses of AI is organising information.

Notion AI can help turn notes into summaries, extract important information and help organise projects and documents.

Imagine finishing a meeting with several pages of notes. Instead of manually going through everything, AI can help identify the main decisions, tasks and important points.

That can be particularly useful for people who spend a lot of their working day in meetings or managing multiple projects.

Best for: Notes, meetings, project organisation and managing information.

So, Which One Should You Use?

There isn't one AI tool that is best at everything.

If you want an all-round assistant, start with ChatGPT.

If your job involves a lot of research, Perplexity is worth exploring.

If you regularly create presentations, Gamma could save you time.

For visual content, Canva AI is a practical option.

And if your problem is keeping track of notes and projects, Notion AI may be more useful.

The bigger lesson is that AI doesn't necessarily have to replace your job to be useful.

Sometimes its biggest benefit is much simpler: taking a task that normally takes an hour and helping you finish it in 20 minutes.

The trick is knowing which tool to use  and knowing when you still need a human to check the work.
