Ten genuinely useful things to do with ChatGPT

ChatGPT does not have to do anything spectacular to be useful. Often it is enough for it to turn a tedious task into a first draft you can review. Summarising an email, organising an idea or preparing questions can save you time without forcing you to trust the tool blindly.

The key is to ask for a specific transformation and keep the original document so you can check the result. If the tool has to decide for you, fill in information you never gave it, or get a current figure right, this is no longer a simple support task.

Short answer

The most reliable uses are the ones that turn information you already know into an output you can check: summarising, sorting, comparing, explaining, preparing and correcting. They are not permission to delegate decisions about money, health, privacy or work.

1. Summarise a long text

Do not just ask it to “summarise this”. Say what you need the summary for:

“Summarise this document in five points, separate the decisions from the outstanding questions, and tell me which parts I should read in the original.”

That gives you a map back to the text, not a version that replaces the source. If the document contains private information, start with an anonymised extract.

2. Turn an email into actions

A long email usually mixes context, requests and things that need no reply. You can ask for:

• the specific action;
• who is responsible, if the message says;
• any date mentioned;
• the question still to be resolved.

If an owner or a date does not appear, the answer should say “not stated”, not invent them. Then compare the list against the email before sending it to anyone else.

3. Organise scattered ideas

When you have loose notes, ChatGPT can group them by topic, duplicates and decisions. Give it permission to organise, but not to change the meaning:

“Group these notes without adding new ideas. Keep the doubtful sentences in a separate section and finish with the three decisions that are still missing.”

This works especially well before drafting a plan, because it makes the contradictions visible.

4. Prepare a work plan

Ask for a short, checkable sequence, not a plan with a hundred tasks. A good request includes the goal, the time limit and the dependencies:

“I have to publish a guide by Friday. Split the work into one-hour blocks, say what depends on a human decision, and leave out anything that needs an external account.”

In my own project I use that separation so as not to confuse strategy, content and technical execution. A useful plan says what comes now and what has to wait.

5. Compare options against the same criteria

You can ask for a comparison table as long as you define the criteria first. For example: total cost, ease of use, privacy, compatibility and support.

The table organises the conversation, but it does not turn the statements into facts. Every important row needs a source or a mark saying it must be checked. Do not compare products using data from different dates without saying so.

6. Explain something without jargon

Say who will read the text and what they already know. “Explain it simply” can produce something childish. It is better to say:

“Explain it to an adult who uses a phone every day but does not know the technical vocabulary. Use an everyday example and define any word that is unavoidable.”

Then remove the metaphors that oversimplify or hide a risk.

7. Prepare questions in order to learn

Instead of asking for a whole lesson, ask for a route:

1. what you need to understand first;
2. a short explanation;
3. a question to check whether you have understood;
4. a small piece of practice.

That format turns the chat into a conversation rather than an endless block of text. If the answer goes into detail you do not need, just ask for the next step.

8. Review something you have written

You can ask it to spot long sentences, repetitions, structural problems or shifts in tone. Protect your own voice with a clear instruction:

“Correct spelling and clarity, but do not change my opinion and do not add facts. Give me a list of changes first and then a revised version.”

Separating the list of changes from the final version lets you decide what to accept.

9. Prepare for a meeting or a difficult conversation

Ask for questions and likely objections, not a script that forces you to perform. State the goal and the limits:

“Prepare six questions to understand the other person’s needs. Avoid intrusive questions and separate the ones that clarify from the ones that decide.”

Rehearsing with a tool can help you organise your thoughts, but the real conversation needs listening and adapting.

10. Create a checklist

Lists are a good output because they let you verify each point. You can ask for one to review a publication, a backup or a purchase:

“Create a list of ten checks to run before publishing a guide. Include title, description, links, image, privacy, sources and final review. Do not mark anything as done.”

That last sentence stops the result looking like evidence of work that has not been done yet.

The pattern behind all ten

The same sequence works in every case:

1. Explain the result you need.
2. Hand over only the context that is needed.
3. Define the format and the limit.
4. Ask it to flag doubts and unverified data.
5. Check the answer against the original material.

OpenAI’s own guidance recommends clarity, specificity and iterative improvement. That is a recommendation about use, not a guarantee of accuracy: reviewing is still part of the job.

Common mistakes

Asking for a summary with no purpose

A summary for making a decision does not have the same shape as one for explaining to somebody else. Say what you will do with it.

Treating an answer as a source

ChatGPT can help you find the questions and the search terms. For current facts, go back to the original source and note the date.

Pasting whole conversations

Remove signatures, phone numbers, names, identifiers and anything unnecessary. Anonymising has to happen before you share the text, not after you get the answer.

Automating a task you do not yet understand

Do the task by hand first. Only then does it make sense to think about whether automating it is worth it.

What I would do

I would start with whatever comes up most often in my week: turning disorganised information into next steps. While building my own platform, summarising documentation was not enough; I needed to tell priorities, decisions and tasks someone else could carry out apart from one another. That distinction stopped the automation mixing up the master plan with the technical work.

Security and privacy

Do not enter passwords, keys, banking details, medical records or confidential documents just to test a feature. Review the controls of whichever service you are using. In ChatGPT you can change the setting that allows new conversations to be used to improve the model; temporary chats have different retention terms, which should be checked in the current documentation.

Conclusion

ChatGPT is worth most when it helps you get from a blank page to a first version you can check. The ten uses above share one simple rule: the tool prepares, organises or criticises; you validate and decide.
