AI That Understands You—and Your Tabs
Imagine researching a complex topic or comparing new tech gear. Feeling lost in a sea of browser tabs? Gemini’s got you. Tap the Gemini icon or use a custom keyboard shortcut, and Gemini will immediately draw concise summaries from articles, clarify dense concepts, and even highlight key specs or pros and cons between products.
Gemini truly standout in Chrome is its instant context awareness. It reads what’s on your screen, sees your open tabs, and delivers responses that actually fit your question—no more generic or off-base answers. Want to dig deeper? Start a chat with Gemini Live, and even get spoken answers, all without leaving your browser window.
Say Goodbye to Tedious Digital Tasks
We’ve all been there—comparing products, organizing notes, booking appointments. Gemini promises to take over the repetitive stuff: extract essential info, summarize whole sites, and soon, automate everyday tasks like rescheduling deliveries or making restaurant reservations. The AI doesn’t just serve up facts; it jumps into action, using the content of multiple tabs to streamline your workflow and decision-making, whether you’re planning your next trip or managing a busy calendar.
Seamless Integration with Google Apps
Gemini doesn’t stop at web pages. It’s deeply woven into the larger Google universe. While browsing, you can pull in schedule info from Calendar, search locations with Maps, or take a shortcut to that key YouTube video snippet, all without opening new tabs or losing your flow. It’s like moving your whole productivity suite into one unified, AI-boosted.
It’s Rolling Out—Here’s What’s Next
Gemini in Chrome is launching first for all U.S.-based macOS and Windows users with English set as their browser language. Mobile users on Android are already in the loop; iOS users will join the party soon with Gemini built right into their Chrome apps. And yes—support for more languages and countries is coming soon.
Why This Changes Everything
Gemini’s debut is far more than a gadget geek’s new toy. It marks a turning point in how we connect with the web, shifting Chrome from a passive gateway to an active, conversational partner.
For creators, researchers, everyday users, and business pros alike, it’s a promise of less friction and more clarity in every browsing session
Notion 3.0 Unleashed: Enter the Age of AI Agents for Real Work
Hold onto your Notion templates—Notion 3.0 has arrived, and it’s seriously reshaping the playing field for knowledge work everywhere. This isn’t a modest update or a shiny add-on. The headline?
AI Agents are now at the center of the Notion universe. Forget basic bots or passive suggestions - these Agents can literally do everything a human can do in Notion: create docs, build complex databases, search across platforms, and trigger multi-step workflows with just a single instruction.
Notion 3.0: Agent is here.
Before, Notion was your tool. With 3.0, Notion is your AI teammate.
It’s the most advanced knowledge work agent. It handles 20+ minute multi-step actions, works with databases, and has a state-of-the-art memory system.

Personalized Intelligence: Your Agent, Your Rules
AI shouldn’t be generic—and Notion’s taken that to heart. With 3.0, customization is king. Craft your Agent’s personality and behavior with dedicated instruction pages, giving it memory and context that grows with every use. Want your Agent to prioritize certain tasks, format outputs a unique way, or remember project quirks? Just spell it out in Notion—it’s as flexible as your imagination.
Bonus points for flair: you can name your Agent and deck it out with digital “accessories” that match your style. And if you’re craving inspiration, browse a library of downloadable Agent templates with skills tailored for everything from onboarding to knowledge base maintenance.
What About Teams? Custom Agents Are Coming
Imagine a future where you have not just one, but a whole fleet of AI specialists, each with its own area of expertise. That’s the promise of Custom Agents, coming soon to Notion 3.0. Run them on schedules or triggers—one updating user feedback, another posting weekly project reports, another handling IT queries automatically, so work keeps humming along long after logging off.
Empowering Busy People, Banishing Busywork
Notion’s mission has always been to help folks build beautiful tools for their life’s work—but too often, that means drowning in busywork. Notion 3.0 flips the script. Hand off the repetitive, time-consuming stuff to your Agent. Whether refining meeting notes into proposals, keeping a knowledge base current, or just tracking your latte obsession, Agents lighten the load and let people focus on what only humans can do.
New Features Galore: Security, Integrations, Control
Here’s the icing: Notion 3.0 isn’t just about Agents. You’ll also find highly-requested features—database row permissions for granular control, new AI connectors, and more MCP integrations to turbocharge your digital workflows. Your data is secure, and with Agent instructions living in Notion pages, you’re always in control of what they do and how they do it.
Ready to Work Smarter? Try Notion 3.0 Today!
Day one of Notion 3.0 is only the beginning. The use cases are practically endless, and the community’s already buzzing with fresh ideas, custom Agent setups, and real-world workflows.
Grok 4 Fast is here!
Grok 4 Fast is xAI's latest advancement in cost-efficient reasoning models, building on large language models (LLMs)—neural networks trained on vast datasets to process and generate responses—with a focus on multimodal capabilities that handle text, images, and potentially voice inputs for more natural interactions.

Grok 4 is also offering lightning-fast performance at low costs, appealing to developers and enterprises seeking scalable solutions without breaking the bank.
With a massive 2 million token context window—tokens being the basic units LLMs break text into for processing—this model excels in long-form reasoning, real-time search integration, and function calling for practical applications like automation and data analysis.
Multimodal Reasoning with 2M Context Window: Processes text and images simultaneously for comprehensive understanding, leveraging a 2 million token capacity to maintain coherence over extended conversations or documents—fundamentals include tokenization (splitting input into manageable pieces) and attention mechanisms (focusing on relevant parts), enabling tasks like analyzing lengthy reports or visual data without losing context.
Lightning-Fast and Cost-Efficient Performance: Delivers similar capabilities to the full Grok 4 but with 40% fewer "thinking tokens" on average, optimized via end-to-end RL training to selectively use external tools or resources—core concepts here involve inference optimization (reducing computational steps) and quantization (compressing model weights for speed), making it ideal for real-time applications at a fraction of the cost.
Advanced Features like Function Calling and Structured Outputs: Supports native tool integration for actions like API calls or data retrieval, alongside structured responses (e.g., JSON formats) for reliable parsing in apps—built on agentic AI principles where models plan and execute steps autonomously, plus voice capabilities with a British-accented assistant for hands-free use, enhancing accessibility and workflow efficiency.
