Most people use ChatGPT for the obvious stuff — writing emails, answering questions, generating ideas. And it’s great at all of those things. But ChatGPT has capabilities that most users never discover, features that can genuinely transform how productive and creative you are. Here are 10 things you probably didn’t know ChatGPT could do in 2026.
1. Analyse Your Spreadsheets
Most people don’t realise ChatGPT Plus can analyse actual data files. Upload a spreadsheet and ask it to identify trends, calculate averages, flag anomalies or summarise the key findings. What used to require a data analyst or significant Excel expertise now takes minutes.
This is particularly useful for small business owners and freelancers who need to make sense of their financial data without hiring an accountant for every query.
2. Act as Your Personal Debate Coach
Want to stress test an argument before presenting it? Ask ChatGPT to argue the opposite position as convincingly as possible. It will identify the weakest points in your reasoning, challenge your assumptions and help you prepare for objections you might not have considered.
This is genuinely useful for anyone preparing for negotiations, presentations, job interviews or difficult conversations.
3. Translate and Localise Content
ChatGPT doesn’t just translate words — it understands cultural context. Ask it to translate a marketing email into French and adapt it for a French audience rather than just converting the words — and it will adjust idioms, tone and cultural references accordingly.
For UK businesses with international customers this is a powerful capability that most users completely overlook.
4. Write and Debug Code in Dozens of Languages
Even if you’re not a developer ChatGPT can write useful code for you. Ask it to build a simple formula for your spreadsheet, create a basic automation script or write a snippet of code to solve a specific problem.
More usefully — if you copy an error message from your computer into ChatGPT it will often explain exactly what’s wrong and how to fix it in plain English. No technical knowledge required.
5. Simulate a Job Interview
Tell ChatGPT the job title and company you’re interviewing for and ask it to conduct a mock interview. It will ask realistic questions, evaluate your answers and give you honest feedback on how to improve.
This is one of the most underused features for job seekers — and it’s completely free on the basic plan.
6. Create a Personalised Study Plan
Tell ChatGPT what you want to learn, how much time you have and what you already know — and ask it to create a structured study plan. It will break down the topic into logical stages, suggest resources and give you a realistic timeline for reaching your goal.
Whether you’re learning a language, preparing for an exam or upskilling for a career change this feature is genuinely powerful.
7. Summarise YouTube Videos and Podcasts
By combining ChatGPT with browser extensions or by pasting transcripts you can get comprehensive summaries of long videos and podcasts in seconds. Instead of watching a 90 minute interview you can get the key insights in two minutes and decide whether it’s worth watching in full.
For busy professionals who need to stay informed without spending hours consuming content this is a game changer.
8. Help You Write a Book
Seriously. ChatGPT can help you plan a book chapter by chapter, develop characters, suggest plot structures, write difficult scenes you’re stuck on and provide feedback on your writing style.
It won’t write the book for you — and you wouldn’t want it to. But as a creative collaborator and thinking partner for long form writing projects it’s remarkably useful.
9. Build a Complete Marketing Strategy
Ask ChatGPT to build a complete marketing strategy for your business — including target audience analysis, key messaging, channel recommendations, content ideas and a 90 day action plan. What would cost thousands from a marketing consultant takes about 10 minutes with a well structured prompt.
The output won’t replace deep industry expertise but it gives any small business owner a solid strategic foundation to work from.
10. Help You Process Difficult Situations
This one surprises people. ChatGPT is genuinely useful as a thinking partner for working through difficult personal or professional situations. Not as a therapist — but as a non-judgmental space to organise your thoughts, consider different perspectives and think through your options clearly.
Many people find that articulating a problem clearly to ChatGPT — and reading back a structured summary of the situation — helps them see it more clearly than they could on their own.
Getting the Most From ChatGPT
The common thread across all of these capabilities is specificity. The more context and detail you give ChatGPT the better it performs. Vague prompts produce generic results. Specific, detailed prompts produce genuinely useful ones.
If you’re not getting the results you want from ChatGPT the answer is almost always to give it more context — who you are, what you’re trying to achieve, what constraints you’re working within and what a good result looks like to you.
ChatGPT vs Claude — Which Should You Use?
For the capabilities described in this article ChatGPT is excellent. But it’s worth knowing that Claude handles many of these tasks equally well — and for writing quality, document analysis and nuanced reasoning Claude often has the edge.
The honest answer is that both tools are worth having in your toolkit. Start with the free plans of both and use each for what it does best.
