ChatGPT Lets You Choose How Nice It Is

Want a friendlier AI assistant—or one that’s all business? OpenAI just rolled out new personalization features in ChatGPT that let you fine-tune how “nice” the AI sounds. Starting December 20, 2025, users can dial up or down traits like warmth, enthusiasm, and even emoji use directly in the app. This update answers a common user request: more control over AI personality without compromising functionality.

Fine-Tune ChatGPT’s Personality to Match Your Mood

Gone are the days of a one-size-fits-all AI tone. With the new “Add Characteristics” menu under Personalization settings, ChatGPT users can now select from preset personalities—like quirky, professional, friendly, or even cynical. You can also manually adjust sliders for specific traits such as how often the AI uses exclamation points, headers, or bullet points. Whether you’re drafting a lighthearted social post or a formal report, the AI can now adapt to your preferred communication style in real time.

Email Editing Just Got Smarter

Beyond personality tweaks, OpenAI has upgraded ChatGPT’s email-writing capabilities. You can now highlight specific sections of text within the chat and ask the AI to revise just that portion—no more rewriting entire prompts to fix a single sentence. The update also introduces in-line formatting, so your emails look polished before you even hit send. This is especially handy for professionals who rely on ChatGPT for quick, clean drafts without sacrificing control over tone or structure.

Why Personalization Matters in 2025 AI

As AI becomes more embedded in daily workflows, user expectations have shifted from raw intelligence to emotional intelligence. OpenAI’s move reflects a broader industry trend: tools that don’t just answer but relate. By giving users agency over ChatGPT’s demeanor, OpenAI boosts accessibility—introverts may prefer a subdued tone, while creatives might crave playful energy. This level of customization not only improves user satisfaction but also aligns with 2025’s SEO and UX priorities: helpful, human-first content that adapts to individual needs.

Easy Access, No Tech Skills Needed

You don’t need to be a power user to access these features. Just open the ChatGPT app, tap the menu icon in the top-left corner, go to your profile, and select “Personalization” > “Add Characteristics.” The interface is intuitive, mobile-friendly, and designed for quick adjustments on the go. OpenAI even included a live preview so you can see how your settings change responses before locking them in—making experimentation effortless.

A Step Toward Truly Adaptive AI

This update signals OpenAI’s deeper commitment to building AI that feels less like a tool and more like a collaborator. By decoupling personality from function, ChatGPT becomes more versatile across contexts—whether you’re brainstorming with a “quirky” assistant or negotiating contracts with a “professional” one. It’s a subtle but significant shift toward AI that respects user preference as much as prompt precision.

What’s Next for ChatGPT Personalization?

While OpenAI hasn’t confirmed future plans, insiders suggest voice tone, response length, and cultural sensitivity settings could be next. For now, the ability to choose how “nice” ChatGPT is marks a user-centric milestone in generative AI. As competition heats up in 2025, the real differentiator won’t just be who has the smartest model—but who makes users feel most understood.
