🤯 What Makes Tabbit Different?
While traditional browsers like Chrome or Safari act as passive windows to the web, Tabbit is an active participant in your workflow. It understands your context, organizes your work, and executes tasks on your behalf.
According to a comprehensive review by 36Kr, the team behind Tabbit chose to "reimagine the relationship between people and information" rather than simply patching AI onto an old framework. The result is a browser that integrates browsing, searching, chatting, and execution into one seamless experience.

⚡ Five Revolutionary Features
Based on hands-on reviews and the official Tabbit website, here are the five core features that make Tabbit stand out in the crowded AI browser market:
1. In-Context Chat — No More Copy-Paste
Tabbit eliminates the friction of switching between tabs and AI chatbots. You can chat directly with the content of any webpage, PDF, or local file without copying and pasting. Simply highlight text, take a screenshot, or reference an entire tab using the "@" picker, and Tabbit understands the context instantly.
2. Model Switching on Demand
Why settle for one AI model when you can have them all? Tabbit supports Auto Mode (which intelligently selects the best model for your task) and Manual Switching between Claude, GPT, Gemini, and more. New state-of-the-art models are added within 12 hours of launch.
DeepSeek V4 Pro Price Drop
DeepSeek recently made headlines with a permanent 75% price cut on V4-Pro — now just $0.435 per million input tokens. Tabbit gives you free access to this powerhouse model, saving you thousands in API costs.
3. Skills — Workflow Automation
Tabbit includes 2000+ agentic skills for the top 100 websites. These aren't just simple shortcuts — they are intelligent workflows that can summarize articles, extract tables from PDFs, auto-organize tabs, generate daily digests, and even conduct competitor analysis. You can also create custom skills from your recurring prompts.
4. AI Agents — Build Once, Use Forever
The Agentic mode allows you to build reusable AI agents for complex tasks. For example, create a SWOT analysis agent that activates on any competitor's website, or a research agent that reads papers, extracts data, and generates reports. These agents remember context across sessions and improve over time.

5. Smart Tags & Favorites — Save Sessions, Not Just Links
Unlike traditional bookmarks, Tabbit saves entire browsing sessions with auto-tagging and full-text search. Filter by topic, revisit complete research sessions, and never lose track of important information again.
🔒 Privacy & Trust: Your Data Stays Yours
In an era where data is the new oil, Tabbit takes a radically different approach. Built by Lumina Lab (registered in Singapore), the browser keeps your history, bookmarks, highlights, and chats encrypted on your device.
When you use an AI model, your prompt goes directly to the model provider you selected — routed to compliant servers in Singapore or your region. Tabbit itself does not relay, log, or mirror your conversations. The company explicitly states: "We don't sell, train on, or share your data with anyone."
💡 Why Should You Care?
Here is the reality: 99% of internet users have not discovered Tabbit yet. While everyone is talking about ChatGPT Atlas (macOS-only, subscription required) or Perplexity Comet, Tabbit offers comparable agentic capabilities completely free, on both Windows and Mac.
As one tech reviewer noted, "Tabbit includes features like context-based AI chat, smart tab organization, and automation tools that help streamline research, content creation, and daily online tasks." Another reviewer called it "the best browser I've encountered among all AI-native browsers when it comes to integrating artificial intelligence capabilities."
Kimi K3 Released
Moonshot AI just unveiled Kimi K3 — a 2.8 trillion parameter open-weight model with 1M token context. It's already available inside Tabbit, giving you frontier-level AI power at a fraction of the cost.
For developers, content creators, researchers, and productivity enthusiasts, Tabbit opens doors that were previously locked behind expensive subscriptions or platform restrictions.
🚀 The Future of Browsing Starts Now
The AI browser war has officially begun. Major tech giants — OpenAI with Atlas, Google with Project Mariner, Microsoft with Edge Copilot — have all set their sights on the browser as the ultimate AI entry point. But Tabbit proves that you don't need to be a trillion-dollar company to build something extraordinary.
