11 ChatGPT Tips Most People Don't Know
11 practical ChatGPT tips: custom instructions, memory, Projects, temporary chat, voice mode, and better prompts — most of them free.
Most people use ChatGPT the same way they use a search box: type a question, read the answer, move on. That works, but it leaves most of the product unused. A few settings and habits — most of them free — turn it from a decent chatbot into an assistant that knows your preferences, keeps your projects separate, and gives you answers you can actually use.
Here are 11 tips most ChatGPT users never discover, roughly in the order you should set them up. Nothing here requires a paid plan unless noted, and every setting path is given so you can find it in under a minute.
1. Set custom instructions once, benefit forever
Open Settings, then Personalization, then Custom Instructions. There are two boxes: one for who you are, one for how ChatGPT should respond. Fill in both. A useful pair looks like this: "I run a small business and I am short on time" plus "Be direct. Answer first, explanation after. Flag uncertainty instead of guessing." From then on, every new chat follows those rules without you repeating them.
2. Turn on memory — then clean it out regularly
Memory lets ChatGPT remember facts across chats: your job, your preferences, the projects you are working on. Turn it on under Settings, then Personalization, then Memory. The part most people skip is maintenance. Open Manage Memories every month or so and delete anything outdated or wrong — stale memories quietly drag down answer quality, and a fact you corrected once can linger for months if you never remove it.
3. Use Projects to keep topics from bleeding into each other
Projects, in the sidebar, group chats with their own files and instructions. Set one up per client, course, or topic. Project instructions apply inside that project and can override your global custom instructions, so a work project can be formal while your personal chats stay casual. If you handle anything sensitive, set the project memory to project-only so what it learns there never colors your other chats.
4. Use temporary chat for anything private
Temporary chat — the button at the top of a new chat — saves nothing to your history and does not feed memory. Use it for salary negotiations, medical questions, or anything you would not want surfacing later as a "remembered" detail. It is the simplest privacy feature in the product, and it costs nothing.
5. Check your data controls
Under Settings, then Data Controls, you can turn off training on your chats. This is a separate switch from memory: turning off training does not delete memories, and turning on memory does not turn on training. If you use ChatGPT for work, set both deliberately rather than assuming one covers the other.
6. Break big jobs into steps
Asking for a complete business plan, report, or essay in one prompt usually produces a long, generic answer. Instead, work in stages: ask for the structure first, approve or fix it, then build one section at a time, critiquing as you go. This is the single biggest quality improvement most users can make, and it works on every plan. It is also exactly what Projects are for — one project, one big job, built in stages.
7. Tell it the format you want, with an example
Vague prompts get vague answers. Instead of "summarize this," say what you want: "Summarize this in five bullet points, each under 20 words, written for a non-expert." If you want a table, say so. If you want the answer first and the reasoning after, say so. One example of the output format you want is worth three paragraphs of description.
8. Use voice mode for thinking out loud
The waveform icon in the message bar opens a real-time spoken conversation. It is genuinely useful for brainstorming, rehearsing a conversation, or working through an outline while you walk or drive — not just a novelty. Switch back to text when you need exact names, numbers, or a carefully structured answer you can copy. Free users get a limited daily voice allowance; paid plans get much more.
9. Turn on web search for anything current
ChatGPT's built-in knowledge has a cutoff date, so for prices, news, rules, or anything that changed recently, use the web search option in the chat. This is the difference between a confident-sounding answer about last year's pricing and a correct one about today's. If an answer matters — a purchase, a deadline, a regulation — ask it to browse and cite what it found, then check the source yourself.
10. Upload files instead of pasting walls of text
Attach documents, spreadsheets, or screenshots with the plus button instead of pasting them into the chat. ChatGPT can summarize a report, pull numbers from a spreadsheet, or explain a screenshot, and keeping the file attached means follow-up questions stay grounded in the same document. Note the limits: free accounts get only a few uploads a day, while paid plans allow far more, so save uploads for the documents that matter.
11. Schedule recurring tasks if you pay for Plus
Paid plans include scheduled tasks: ask ChatGPT to check something or send you a summary on a schedule, such as a weekly roundup of news in your field or a daily reminder to review your to-do list. It is easy to forget this exists, because it lives in the sidebar rather than the chat box, but it turns ChatGPT from something you visit into something that works while you are away.
Bonus habit: follow up instead of starting over
When an answer is close but not right, do not open a new chat and retype the question. Reply in the same conversation and say exactly what to change: "Shorter," "Less formal," "Keep the first two points and rewrite the third with an example." Each follow-up narrows the result, and it is usually faster than a fresh prompt. The same habit applies to mistakes: when ChatGPT gets something wrong, correct it in the conversation rather than silently accepting it, because the correction shapes everything that follows. If a prompt works especially well, save it somewhere outside ChatGPT — a note, a document, a project file — so you can reuse it instead of reinventing it next month.
What to skip
Not every feature deserves your time. Endless prompt templates copied from social media usually underperform a short, specific prompt written for your actual task. And do not pay for a higher plan just for one feature: ChatGPT's plans in 2026 run from free, through Go at $8 a month and Plus at $20 a month in the US, up to Pro tiers starting at $100. Check the official pricing page before upgrading, because plans and limits change often — and because the free plan already covers most of the tips above.
The bottom line
Five minutes in Settings, then Personalization — custom instructions, memory, and data controls — improves every conversation you will ever have with ChatGPT. None of these settings are permanent, either — if a change makes answers worse, turn it off and try something else. The best setup is the one that matches how you actually work, not the one a guide told you to copy. Add Projects for your big jobs, temporary chat for private ones, and staged prompts for anything long, and you will get noticeably better answers from the same tool you already have.
