I ignored this ChatGPT setting for months — now I use it every day
Like millions of others, I use ChatGPT daily. As a power user, I frequently use ChatGPT to summarize research, create images and I even use the bot to talk me down from a spiral of indecision.But recently, I revisited an underused setting buried in the app that completely changes how the bot responds. It's so useful that I really wish I had taken advantage of it sooner.
No, it's not a secret plugin or a pro-only feature. It's something that's been there the whole time: custom instructions.
You've probably seen the button dozens of times but never bothered to click on it. It lives quietly in your settings menu under the heading: 'Customize ChatGPT.' This customizes the chatbot's behavior.
Using customized GPTs dramatically improved how I interact with the AI by tailoring the chatbot to my specific needs.Think of it as crafting perfect assistants for certain tasks. Instead of re-explaining your preferences every time, a custom GPT can be set up to understand your job, writing style, tone and even the kind of responses you want (short, long, complex, simple).Custom GPTs also support powerful tools and integrations. You can grant them access to a code interpreter, web browsing, image generation or even custom APIs and uploaded files.Using this feature turns ChatGPT into an even better assistant capable of analyzing data, generating visuals or referencing your documents without extra work on your part. Plus, you can set behavioral instructions so the GPTs always respond in your preferred tone or format, saving you time and improving consistency.
For me, the hardest part about using a customized GPT is literally remembering to use it. Although it's just a click away, sometimes I'll dive into a prompt before I remember there's a better way to get the best response.Once you've built a custom GPT that works well, you can reuse it as often as you like or share it with others (a great asset for teams). Whether you're managing SEO, writing emails or brainstorming ideas, having a GPT fine-tuned to your process means faster, smarter output. It's a useful way to turn a general-purpose tool into a personal or professional super-assistant.
If you're like me, you'll notice that when you finally start customizing GPTS, your experience with AI will shift entirely, and for the better.
Your responses will feel clearer and far more personal. You won't get generic responses, but answers that fit your style and suggestions that are more engaging.
Get instant access to breaking news, the hottest reviews, great deals and helpful tips.
You can access this feature in just a few taps:
Click your name (or the three dots in the bottom left)
Tap Settings
Select Custom Instructions
You'll see two key fields:
'What would you like ChatGPT to know about you to provide better responses?'(Example: 'I'm a busy mom of three and want an empathetic, conversational tone that feels like I'm chatting with a friend.'
'How would you like ChatGPT to respond?'(Example: 'Use short paragraphs, avoid buzzwords, and give practical suggestions. Add a human tone, like you're texting a smart coworker.')
Once you fill these out, that context is baked into every conversation. You don't have to reintroduce yourself or explain your tone again. ChatGPT just gets it.
Custom instructions are convenient because they are like having a hat trick in your back pocket. Whatever issue you were having with ChatGPT earlier, such as answers feeling too generic or formal, this setting fixes it.It turns the chatbot into something much closer to a real assistant and one that actually understands everything about you (well, as much as you feel comfortably telling it).
It also means you'll spend less time rewriting responses and more time getting useful results. For example:
When I asked it to write a note to the babysitter, it used formatting and tone I'd normally have to adjust.
When I needed a list of birthday party locations in the area, it knew where I lived and pulled them up immediately. (This type of ultra personalization might not be for everyone, but I find it to be a time saver).
And when I asked for snack ideas for the soccer team, the list actually sounded like something I'd submit (and easy enough for a busy mom to contribute); not something from a generic listicle generator.
Best of all? It feels more personal without sacrificing quality responses.
If you're using ChatGPT with memory enabled, custom instructions are the perfect complement. Memory helps the chatbot remember ongoing preferences and facts across conversations, while custom instructions give it a solid starting point for every new chat.
Even if memory isn't your thing, these static instructions make ChatGPT far more efficient right out of the gate.
This one setting changes how well ChatGPT can work for you. If you've been using the chatbot like a search engine or idea machine, custom instructions push it into a new category making it more like a personal AI assistant.
You'll notice a difference when it starts answering like someone who knows your voice, your goals and how you think.

Warren Buffett Might Not Own These Artificial Intelligence (AI) Stocks -- but Their Fundamentals Check Out
Warren Buffett has long advocated for buying stocks with a competitive advantage. Alphabet dominates web search and trades at a modest valuation. TSMC is the leader in semiconductor manufacturing and is growing rapidly in the AI era. 10 stocks we like better than Taiwan Semiconductor Manufacturing › Though Apple has been Berkshire Hathaway's (NYSE: BRK.A) (NYSE: BRK.B) top holding for several years, Warren Buffett has historically avoided tech stocks. The renowned value investor has said that he can't forecast earnings for tech companies as they are less predictable, due in part to the changeable nature of technology, than other sectors. Buffett has historically preferred to invest in sectors like insurance, banking, utilities, energy, and consumer staples that have predictable cash flows, and whose industries don't change much over time. Based on that philosophy, it's not a surprise that Buffett has mostly avoided artificial intelligence (AI) stocks. However, there are some that fit in well with his approach to investing -- buying companies with sustainable competitive advantages at attractive valuations. Keep reading to see two stocks that fit the bill. Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) has one of the strongest economic moats in business history. Google has had more than 90% market share in the web search industry for the last two decades. The brand is synonymous with search, and underpins Alphabet's larger, highly profitable tech empire that includes products like YouTube, Google Cloud, the Chrome web browser, and "moonshots" like the Waymo autonomous vehicle program. Google Search has now reached a revenue run rate of $200 billion, and Google Services, of which search makes up most of its business, has an operating margin of more than 40%. Alphabet is also still delivering steady growth with revenue up 12% in the first quarter. You might think that a company like Alphabet with evident competitive advantages, solid growth, and massive profits would trade at a premium valuation, but that's not the case. Alphabet currently trades at a price-to-earnings ratio of just 18.6, a substantial discount to the S&P 500. There are two primary reasons for the discount in valuation. First, investors are fearful that the company could get broken up or face a substantial fine or a related punishment as it's been found to have a monopoly in both search and adtech. Separately, Alphabet also seems to be trading at a discount because of the risk that its search empire could be disrupted by an AI chatbot like ChatGPT or Perplexity. While those are risks for Alphabet, shares have long traded at a modest valuation, meaning investors have historically underestimated the stock. Given that, investors may want to borrow from Buffett's mentality and buy Alphabet stock. Berkshire Hathaway invested in Taiwan Semiconductor Manufacturing (NYSE: TSM) in 2022, buying $4.1 billion of the stock, but it sold out of that position completely just two quarters later. It wasn't clear why. It could have been because of the risk of an invasion by China into Taiwan. Like Alphabet, Taiwan Semiconductor (also known as TSMC) has one of the strongest economic moats in the business world. The company is the leading third-party semiconductor manufacturer with a market share of more than 50% in contract chips and more than 90% of advanced chips that are crucial for AI. TSMC is the company that Apple, Nvidia, AMD, Broadcom, and other top semiconductor and tech companies turn to to manufacture their chips. In the first quarter, advanced chip technologies accounted for 73% of its total wafer revenue. Its technological lead in a highly technical industry with high capital expenditures, and its customer relationships, give the company a significant competitive advantage. TSMC is also growing quickly, with revenue up 35% in the first quarter to $25.5 billion, and its operating margin improved to 48.5%, showing the company has significant pricing power. Like Alphabet, TSMC is also cheaper than you'd expect for a company that's so dominant. The stock currently trades at a price-to-earnings ratio of 24, which is an excellent valuation for a business growing as fast as TSMC, and one that is a linchpin in the artificial intelligence boom. It may never be clear why Berkshire Hathaway sold TSMC, but it's not surprising that Buffett's conglomerate bought it. In many ways, it looks like a classic Buffett stock.

The 3 Best Growth Stocks to Buy With $100 Right Now
Growth stocks faced significant volatility so far in 2025, but many outperformed last month. These three stocks have all been sold off by the market for various reasons. But they now trade at compelling values with great long-term prospects. 10 stocks we like better than Marvell Technology › Growth stocks have been some of the best-performing investments over the last few years, but 2025 brought some challenges for growth investors. The increased volatility from growing global trade tensions and economic uncertainty hasn't been kind. Nonetheless, the S&P 500 Growth index has managed to eke out some outperformance of the S&P 500 index over the last month or so. With more downside from factors like tariffs priced into many growth stocks now compared to the beginning of the year, there could be room for them to continue outperforming through the rest of the year and beyond. Still, investors should remain mindful to be sure they're getting good value for the price they're paying. You can still overpay for a great growth stock. Importantly, you don't need a lot of money to get started with investing. Even if you have just $100 available to invest, you can buy shares in any of the following three great growth stocks that could outperform over the coming years. Marvell Technology (NASDAQ: MRVL) is a chip designer that's been a big beneficiary of the growth in artificial intelligence spending. There are two primary areas where Marvell's business benefits from the strong growth in generative AI infrastructure: its custom AI accelerators and its networking chips. Marvell is the company behind Amazon's Trainium 2 custom AI accelerator, and it recently won Amazon's Inferentia order to make its custom AI inference chips. It also works with the three other hyperscalers (Microsoft, Alphabet, and Meta Platforms) for various data center chip designs, including Microsoft's Maia AI accelerator. Marvell's stock has been beaten down over concerns about hyperscalers working with other chip designers, like AIchip. However, management reported that it secured deals wth both Amazon and Microsoft to design their next-generation AI accelerators during the company's first-quarter earnings call. That said, given the demand for custom silicon, it's not unreasonable to see one or both of them use a secondary source to supplement Marvell. Marvell also makes networking chips, and it holds a particular advantage in optical modules that transfer data using light. Marvell's chips enable servers to communicate data with each other faster, increasing the efficiency of each cluster's performance. As data centers and clusters grow bigger and bigger, demand for Marvell's networking chips stands to grow considerably. Marvell stock trades for around $65 per share as of this writing. That gives it a forward P/E of just 23, which is an exceptional value considering the growth prospects ahead of it. While the growing reliance on a few select customers makes the company risky, it looks secure in its ability to hold onto those customers and grow its business. And given the price, there's less downside to the stock than just a few months ago when it traded at more than twice the price. Block (NYSE: XYZ) is the company behind Cash App and Square. It disappointed investors recently due to a shortfall in Cash App's gross profit growth in the first quarter. But the recent sell-off could be a great opportunity for growth investors. Cash App aims to increase revenue per user through growing spend on the Cash Card (where it collects interchange fees) and expanding the number of services its users engage with in the app. The more services a user takes, the more likely they are to stick with the app. Its most recent service is Cash App Borrow, which gives users small, short-duration loans. The new product could help address the core issue leading to disappointing results for Cash App last quarter: a slowdown in spending. That result speaks to the more vulnerable nature of Cash App's core users. In an economic slowdown, Cash App users may be the first to cut back on spending. Major credit card networks notably didn't see a slowdown last quarter. The Square side of the business remains a leader in onboarding small businesses. It's focused on several core verticals, including restaurants, beauty, and services businesses. That's enabled it to build out a core software stack that makes it easy for small businesses to get up and running on its platform and start transacting. That's produced predictable growth and return on customer acquisition spending as it continues to grow its share of the microbusiness market while working to move upstream to bigger businesses. Block's current share price of around $63 is just 16.5 times analysts' estimates for 2026 earnings. While Block is expected to see an earnings dip this year, it should quickly recover in 2026, surpassing 2024 earnings. While short-term economic uncertainty has weighed on the stock (as it should), the long-term outlook remains strong thanks to its growing ecosystem and the network effect driving customer growth and retention. DraftKings (NASDAQ: DKNG) is one of the largest sports betting companies in North America. The company successfully leveraged its brand in Daily Fantasy Sports to rapidly expand into sports betting after a Supreme Court ruling legalized it in 2018. That brand strength gives it a significant advantage in the sports betting market. That's seen in its ability to attract about 400,000 new monthly unique payers to its platform over the past year despite increased competition from well-known brands like ESPN and Fanatics. But the growing popularity of DraftKings creates a second advantage for the business: more and better user data. Data is an extremely valuable asset in sports betting. Better data means more accurate and up-to-date money lines, more personalized and effective promotions, and faster expansion into new bet types, like in-game parlays. It can also help identify sharp bettors and mitigate the losses the sportsbook makes, and identify acquisition opportunities like DraftKing's recent Jackpocket purchase. DraftKings faces potential headwinds from lawmakers and regulators. Illinois recently passed a new tax law requiring sportsbooks to pay $0.25 per bet for the first 20 million bets and $0.50 per bet thereafter. DraftKings may be better positioned to absorb taxes like that than smaller sportsbooks with less regional coverage. DraftKings can shift its marketing focus to friendlier states where it can generate better profit margins. DraftKings did lower its revenue and earnings before interest, taxes, depreciation, and amortization (EBITDA) expectations alongside its first-quarter earnings report. Still, at just $34 per share, the stock trades for an enterprise value-to-forward-EBITDA ratio of about 21 based on management's outlook for 2025. Management's long-term outlook calls for an average EBITDA growth of 35% for 2026 through 2028 based on its 2025 outlook. That makes the current price a great value for growth investors.

Amazon Eyes AI-Powered Humanoid Robots for Last-Mile Edge
Amazon (NASDAQ:AMZN) stock popped about 2.7% yesterday after word got out that the e-commerce giant is quietly building a humanoid park in San Francisco to experiment with AI-powered robots for deliveries. Warning! GuruFocus has detected 2 Warning Sign with AMZN. Instead of relying solely on its 750,000 warehouse bots, Amazon is now eyeing humanoid prototypessome coming from China's Unitreethat can literally hop out of a Rivian (RIVN) delivery van to drop packages at your doorstep. Right now, engineers are fine-tuning navigation, object handling and safety systems in a mock urban environment, complete with a single Rivian van parked among obstacles. Meanwhile, over at Amazon's Lab126 in Sunnyvale, a fresh agentic AI team is working on getting these robots to understand and act on natural language commandsimagine telling a bot, Pick up that package and leave it by the back door and having it do just that. All of this is part of Amazon's broader push to shave billions off its fulfillment and delivery bills (which topped $60 billion last year) and stay a step ahead of rivals like Walmart (NYSE:WMT) and FedEx (NYSE:FDX). While timelines are still fuzzy, CEO Andy Jassy hinted that pilot tests could roll out in select cities later this year. Investors should care because if these humanoid bots make it from test park to real-world routes, Amazon could cut costs, boost delivery speeds and create a new benchmark in last-mile logistics.
