Your ChatGPT history is a personality test you didn’t know you were taking

Every time you ask ChatGPT to draft an email, vent about a relationship problem, or look up symptoms, you might be handing over more than just a query. Researchers at ETH Zurich have trained an AI model to predict personality traits directly from real ChatGPT conversation logs, and it was scarily good at recognizing personality traits. This breakthrough raises serious questions about privacy, data ethics, and how companies might use your digital footprint.

As reported by TechXplore, the study collected 62,090 real conversations from 668 ChatGPT users. Participants also completed a standard personality test, giving the researchers a baseline to measure against. The AI was then trained to classify each user as low, medium, or high across the five traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism. The fine-tuned model beat random chance across all five traits, with extraversion being the easiest to predict, achieving up to 44% higher accuracy than guessing.

Does it matter what you talk about with ChatGPT?

Absolutely. The study found that chats involving mental health topics made extraversion particularly easy to infer. Discussions about religion were strongly linked to conscientiousness inference, and conversations about mental state and mood made openness more predictable. Even seemingly casual conversations contained enough signal to be useful. The researchers also found that the more you use ChatGPT, the easier you become to profile.

This means that your everyday questions—from asking for cooking recipes to complaining about work—are not as neutral as they seem. Each exchange adds a small piece to a larger puzzle that AI can assemble into a detailed personality portrait. Given how much data we share with ChatGPT, it matters a lot whether it can easily discern our personality traits.

Why does ChatGPT personality prediction matter beyond the research lab?

The researchers are clear about the implications. Service providers already have access to all of this data, and with over 800 million monthly ChatGPT users as of January 2026, the scale of potential profiling is enormous. A personality profile built from your chat history could be used for targeted advertising, personalized persuasion, or in worst-case scenarios, large-scale influence campaigns.

Recently, ChatGPT has started integrating ads. With the data it has on hands for us, think how easily it can format the ads to manipulate our thinking. For instance, if the AI knows you are high in neuroticism, it might show you ads for anxiety relief products or financial planning services that prey on your fears. Similarly, an extraverted user might see ads for social events or networking tools.

How accurate is the personality profiling?

The study’s accuracy is impressive but not flawless. Extraversion was the easiest trait to predict, achieving up to 44% higher accuracy than random guessing. However, other traits like openness and agreeableness were more challenging. Still, as AI models improve, so will their ability to read us. The researchers note that even a modest improvement in prediction accuracy can have significant real-world consequences when applied to hundreds of millions of users.

What can you do to protect your privacy?

For now, it is worth remembering that your AI chatbot is not a diary. At least not a private one. You can also take a proactive approach and delete your ChatGPT history regularly to remove your personal chats from its memory. This simple habit can significantly reduce the amount of data available for profiling.

Additionally, consider reviewing your privacy settings on all AI platforms. Many services allow you to opt out of data collection for training purposes. You might also want to avoid sharing highly sensitive personal information—like mental health struggles or financial details—in conversations with chatbots. If you need advice on such topics, consult a human professional instead.

Building on this, it’s wise to treat every chatbot interaction as potentially public. Think before you type: would you be comfortable if this conversation appeared on a billboard? If not, it’s probably best not to share it with an AI.

The bigger picture: AI and the future of targeted advertising

This research highlights a growing trend: the convergence of AI and psychology for commercial gain. Companies like Google, Meta, and OpenAI are sitting on vast troves of conversational data. With the right algorithms, they can turn that data into detailed psychological profiles for hyper-targeted advertising.

However, there are also ethical implications. If AI can predict your personality from chat logs, it could be used to manipulate your decisions—from what you buy to how you vote. Regulators are beginning to take notice, but the technology is moving faster than the law. As a result, individual vigilance is currently the best defense.

In conclusion, your ChatGPT history is more than a log of queries—it’s a window into your personality. While the technology is fascinating, it also demands caution. Stay informed, protect your data, and remember: in the digital age, your words have power beyond what you imagine.

Microsoft Copilot Cowork Goes Mobile: Now Your AI Can Finish Tasks While You’re Away

Microsoft is pushing its artificial intelligence beyond simple Q&A. The company wants Microsoft Copilot Cowork to actually start and complete tasks on your behalf, not just suggest answers. Originally launched through the Frontier program earlier this year, this AI assistant is now taking a major leap forward with mobile support, new skills, and deeper integrations.

On May 5, 2026, Microsoft CEO Satya Nadella announced a set of updates that significantly expand what Copilot Cowork can do. The biggest news? It’s finally available on smartphones, meaning you can delegate work from anywhere and pick it up later on your desktop. No more being tied to a laptop to get things done.

Copilot Cowork Arrives on iOS and Android

Perhaps the most anticipated update is the launch of Copilot Cowork on both iOS and Android. This means you can now think of a task during your commute or between meetings, hand it off to the AI, and return to a finished result. The system keeps working even when you close your phone.

This approach mirrors what Anthropic introduced with Claude Dispatch in March 2025. However, Microsoft’s version is tightly woven into the Microsoft 365 ecosystem, giving it an edge for business users who rely on Outlook, Teams, and other productivity tools.

As a result, you can start a research task on your phone, review progress on your tablet, and finalize a document on your desktop—all without losing momentum. This seamless continuity is a game-changer for remote workers and busy professionals.

Introducing Copilot Skills: Custom Instructions for Repetitive Tasks

The second major update is the introduction of Copilot Skills. A skill is essentially a saved set of instructions that tells the AI how to handle a task your way—with your preferred tone, structure, and process. Microsoft is rolling out built-in skills for common workflows like creating documents, coordinating meetings, and conducting research.

But the real power lies in customization. You can build your own custom skills for recurring work or team processes you want to standardize. For example, a marketing team could create a skill that generates blog posts in a specific brand voice, while a sales team might set up a skill for drafting client proposals with standard pricing tables.

Building on this, custom skills can be shared across teams, ensuring consistency and saving time on repetitive tasks. This feature alone could transform how organizations approach routine work.

New Integrations and Connectors Expand Copilot’s Reach

Copilot Cowork is also getting deeper integrations across Microsoft 365. The AI now connects with Power BI through Fabric IQ and Dynamics 365 for sales and customer service workflows. This means you can pull real-time data from connected services to create reports, pitch decks, and more.

Third-party connectors for platforms like Miro, monday.com, LSEG, and S&P Global Energy are coming soon. These connectors will greatly enhance the AI’s ability to fetch and synthesize data from external sources, making it a more versatile tool for complex projects.

However, it’s worth noting that Copilot Cowork is still rolling out through the Frontier program. Not all features may be available to every user immediately. Microsoft is moving fast, though, and the company has hinted at broader availability in the coming months.

What This Means for Your Workflow

If you’ve been waiting for an AI that actually does the work rather than just describing it, Copilot Cowork is worth a serious look. The combination of mobile access, reusable skills, and deep integrations creates a powerful productivity assistant that can handle everything from email management to complex data analysis.

In addition, the ability to delegate tasks while on the go means you can reclaim time that was previously lost to context switching. Instead of jumping between apps and devices, you can simply tell Copilot what to do and move on to higher-value work.

Ultimately, Microsoft is betting that the future of work is asynchronous and AI-driven. With Copilot Cowork, that future is arriving faster than many expected.

ChatGPT for Excel and Google Sheets Is Now Out of Beta — Here’s Why It Matters

If you spend hours wrestling with spreadsheets, there’s good news. ChatGPT for Excel and Google Sheets has officially exited beta and is now available to all users. OpenAI first introduced the Excel integration in March, followed by a Google Sheets version in April. Now that the public rollout is complete, this development is a significant step forward for anyone who relies on data tables for daily work.

What does this mean in practice? You no longer need to switch between tabs or copy-paste data into a separate chatbot. The AI lives inside your spreadsheet, ready to assist with everything from building a budget tracker to cleaning up messy datasets. This is not just a convenience — it fundamentally changes how you interact with numbers and formulas.

How ChatGPT Transforms Spreadsheet Workflows

The core advantage is simplicity. Instead of memorizing complex functions or hunting through help forums, you can describe what you need in plain English. For instance, type “create a monthly expense tracker with categories and totals,” and ChatGPT will generate the entire workbook structure. Similarly, if you have an existing sheet, you can ask the AI to update formulas, add new scenarios, or reformat outputs — all without touching a single cell manually.

This capability is a game-changer for AI spreadsheet tool adoption. Power users managing financial models or multi-tab dashboards will find it invaluable for speeding up repetitive tasks. However, even casual users benefit: building a personal budget from a prompt is far less intimidating than starting from a blank sheet. The barrier to entry for spreadsheet mastery has dropped significantly.

Formula Creation Made Simple

One of the most praised features is formula generation. Instead of writing complex nested functions, you can say, “Calculate the average sales per region, excluding outliers,” and ChatGPT produces the correct formula. This is especially helpful for intermediate users who understand logic but struggle with syntax. As a result, Google Sheets ChatGPT integration empowers users to achieve more with less effort.

Data Cleanup and Question Answering

Another standout feature is the ability to ask questions about your own data. If a formula returns an unexpected result or you suspect an error in the dataset, simply type your query. ChatGPT scans the sheet and provides a clear explanation. This eliminates the guesswork and reduces debugging time.

For example, imagine you see a cell showing #REF! and you’re not sure why. You can ask, “Why is this formula broken?” and the AI will diagnose the issue, such as a deleted column or mismatched range. Similarly, you can request data cleanup: “Merge duplicate rows in column A and sum the values in column B.” The AI handles it instantly.

This functionality aligns with the broader trend of Excel AI integration, where artificial intelligence acts as a co-pilot rather than a replacement. It augments human decision-making by handling tedious tasks.

Availability and Pricing

The integrations are now globally available across all subscription tiers: Pro, Plus, Business, Enterprise, Edu, and K-12 plans. This means students, freelancers, and large corporations can all access the same features. Whether you use Microsoft Excel or Google Sheets, the experience is consistent.

For those new to automated formulas, starting is straightforward. Open your spreadsheet, activate the ChatGPT add-in (available in the respective app stores), and begin typing prompts. The AI learns from context, so the more you use it, the more accurate its suggestions become.

What This Means for the Future of Work

Spreadsheets remain the backbone of data analysis in countless industries. By embedding ChatGPT directly into Excel and Sheets, OpenAI is making advanced data manipulation accessible to everyone. The days of memorizing hundreds of functions are fading. Instead, we are entering an era where natural language becomes the primary interface for data work.

This shift will likely accelerate adoption of spreadsheet automation across small businesses and non-profits, where technical expertise is often limited. It also raises the bar for what users expect from productivity software. As AI continues to evolve, we can anticipate even deeper integrations — perhaps where the AI predicts your next move or proactively suggests improvements.

In summary, the exit of ChatGPT for Excel and Google Sheets from beta is more than a routine update. It’s a signal that AI-powered tools are becoming mainstream in everyday workflows. Whether you are a data analyst or a budget-conscious student, this integration offers tangible benefits. Try it out and see how much time you can save.
