You’re Probably Only Using 20% of What ChatGPT Can Do
Most people open ChatGPT, type a question, read the answer, and close the tab. That’s a bit like buying a Swiss Army knife and only ever using the main blade.
ChatGPT is packed with capabilities that go way beyond basic Q&A, and the majority of users never discover them. Whether you’ve been using the platform for two weeks or two years, there’s a solid chance some of the best ChatGPT features on this list will genuinely change how you use the tool. Let’s dig into what you’re missing.
Custom Instructions: Teaching ChatGPT Who You Are
This one alone is worth the price of a Plus subscription, even though it’s technically available on the free tier. Custom Instructions let you tell ChatGPT persistent information about yourself and how you want it to respond, so you don’t have to re-explain your context every single conversation.
You’ll find it under your profile menu. There are two fields: one for background information (who you are, what you do, relevant context), and one for behavioral preferences (how formal you want responses, whether to use bullet points, how long answers should be). Once you fill these out, every conversation starts with that baseline already in place.
A freelance writer, for example, might set their instructions to something like: “I write for B2B SaaS companies. My clients prefer plain language and short paragraphs. Never use jargon unless I specifically ask for it.” From that point on, ChatGPT writes with that style in mind without being reminded.
It’s one of the most underused ChatGPT features out there, and it takes about three minutes to set up. If you haven’t touched it yet, that’s the first thing you should do after reading this.
Memory: ChatGPT That Actually Remembers You
Building on Custom Instructions, ChatGPT now has a proper Memory feature that lets it save specific facts across conversations. This isn’t the same as looking back at your chat history. It’s an active, evolving record of things you’ve told it or that it’s learned about you over time.
You can tell ChatGPT directly: “Remember that I’m a vegetarian” or “Remember that I prefer metric units.” It stores that information and applies it going forward. You can also view, edit, or delete any memory entry at any time through the settings menu under “Personalization.”
This transforms ChatGPT from a stateless assistant into something much closer to a real working partner. If you’ve ever been frustrated by having to repeat your preferences, your job title, or your project context every time you start a new chat, Memory is the fix. It’s one of those chatgpt hidden features that isn’t heavily marketed, but once you use it, going back feels genuinely annoying.
GPT-4o’s Vision Capabilities Are Underused by Almost Everyone
A lot of people know ChatGPT can generate images with DALL-E. Far fewer use it the other way around: uploading images and asking ChatGPT to analyze them.
GPT-4o has strong vision capabilities built right in. You can upload a photo of a broken appliance and ask what’s wrong. You can paste in a screenshot of a spreadsheet and ask it to interpret the data. You can photograph a restaurant menu in another language and have it translated instantly. You can upload a diagram, a whiteboard sketch, or a graph from a report and ask specific questions about what it shows.
For professionals, this is huge. Designers can upload mockups and get detailed feedback. Developers can photograph handwritten system diagrams. Teachers can scan student work and ask for assessment notes. These are genuinely practical chatgpt tips tricks that most people scroll right past because they’re used to thinking of ChatGPT as a text-only tool.
To use it, just click the paperclip or image icon in the chat input box and upload your file. That’s it.
Voice Mode: Not Just a Novelty
Most people tried voice mode once, thought “huh, neat,” and never opened it again. That’s a mistake, because the advanced voice mode in ChatGPT is genuinely useful for specific workflows.
Hands-free brainstorming while you’re cooking or driving is the obvious use case. But it goes deeper than that. You can use voice mode to practice a presentation out loud and get real-time feedback. You can use it to rehearse a difficult conversation, like a salary negotiation or a client call, with ChatGPT playing the other person. Language learners have been using it to practice speaking in their target language with a patient, responsive conversation partner that never gets tired of being corrected.
The real-time interruption capability is also impressive. Unlike older voice assistants, GPT-4o’s voice mode can handle genuine back-and-forth, not just command-response pairs. If you haven’t given it a serious second look, it’s worth 15 minutes of your time.
The System Prompt You Didn’t Know You Could Write
Here’s one of the more powerful chatgpt tips tricks that power users rely on heavily: you can effectively write your own system prompt at the start of any conversation by front-loading your instructions before asking anything.
Instead of just diving into your question, start the conversation with a framing paragraph. Something like: “For this entire conversation, you are a skeptical editor who pushes back on weak arguments. Don’t agree with me unless you genuinely think I’m right. Use Socratic questioning. Keep responses under 150 words.” Everything that follows will adhere to those rules for the whole session.
This approach gives you a level of control over ChatGPT’s behavior that feels almost like programming it. Combine it with Custom Instructions and you’ve essentially built a personalized assistant with a consistent persona and working style. Researchers, writers, strategists, and coaches use this kind of framing constantly, and it’s completely free to do on any plan.
Code Interpreter and Data Analysis: More Than a Party Trick
Under the “Tools” menu in a ChatGPT Plus conversation, you’ll find access to the Code Interpreter, sometimes called Advanced Data Analysis. This is one of the best ChatGPT features for anyone who works with data, even if you have zero coding knowledge.
You can upload a CSV file and say, “Show me a summary of this data, find any anomalies, and create a bar chart of monthly sales.” ChatGPT will write and execute Python code in real time, show you its work, and produce a downloadable chart. You can ask follow-up questions, request different visualizations, or ask it to clean the data before analyzing it.
For small business owners, marketers, or anyone who drowns in spreadsheets, this feature replaces hours of manual work. A task that would normally require a data analyst or a working knowledge of Excel pivot tables can take under five minutes. It’s one of those chatgpt features you need to actually see in action before you understand how significant it is, because describing it doesn’t quite do it justice.
Creating and Using Custom GPTs
ChatGPT Plus users can build their own Custom GPTs, and it’s easier than you’d expect. Through the “Explore GPTs” section, you can create a specialized version of ChatGPT with its own name, personality, instructions, and even uploaded knowledge files.
A business owner might build a Custom GPT trained on their company’s style guide and product documentation, so it always answers customer questions consistently. A teacher might build one loaded with their course curriculum. A developer might create one configured to generate code in their company’s specific architecture and naming conventions.
Even if building your own sounds like too much effort, the GPT Store has thousands of already-built Custom GPTs you can use instantly. There are GPTs for legal research, meal planning, SEO writing, scientific literature review, and hundreds of other niches. Browsing what’s already available is a quick way to discover what’s genuinely possible, and it’s one of those chatgpt hidden features that most casual users never even click on.
Browsing the Web in Real Time
ChatGPT’s training data has a knowledge cutoff, but with the browsing tool enabled, it can search the web in real time during your conversation. This isn’t just useful for current events. It’s useful any time you need up-to-date pricing, recent product reviews, live documentation for software, or fresh research on a fast-moving topic.
The browsing feature will cite its sources, so you can verify what it’s pulling. It’s not a replacement for doing your own research, but it dramatically speeds up the early stages of any research task. Pair it with the follow-up questioning style mentioned earlier, and you can go from knowing nothing about a topic to having a well-structured brief in 20 minutes flat.
Sharing and Collaborating on Conversations
This one is small but useful. ChatGPT lets you generate a shareable link to any conversation. If you’ve built out a complex research thread, a detailed plan, or a lengthy brainstorm with a lot of useful outputs, you can share that entire conversation with a colleague, client, or friend with a single link. No copy-pasting, no screenshots, no forwarding long email chains.
It’s a simple feature, but it makes ChatGPT a better collaborative tool. Teams that are starting to build workflows around AI often miss this, and then they manually copy outputs into documents when they could just share the link directly.
Stop Leaving These Features on the Table
The gap between casual ChatGPT users and power users isn’t really about intelligence or technical skill. It’s about exploration. Most of these underused ChatGPT features are built right into the interface, waiting to be clicked. Custom Instructions, Memory, vision uploads, Code Interpreter, Custom GPTs, real-time browsing: none of these require any special knowledge to use, they just require you to poke around.
Pick one feature from this list that you haven’t tried yet and spend 20 minutes actually using it this week. That’s a more valuable investment than reading another article about AI’s potential. The best way to get more out of ChatGPT is to actually use more of it.
