Tabbit
Tabbit is an AI-native browser that understands your context. Chat with webpages, drop in tabs, files, screenshots or highlighted elements with @ anything, automate tasks with Agent Mode, and create custom Skills. It bundles site MCPs, agent memory, smart tab organization, favorites with full-page saving, multilingual translation, and support for top models like GPT, Claude, and Gemini, with local-first privacy. Free for macOS and Windows.
What is Tabbit?
Tabbit is an AI-native desktop browser for macOS and Windows, developed by Lumina Lab (LUMINALAB PTE. LTD., registered in Singapore). Unlike traditional browsers that treat AI as an add-on, Tabbit is built around context: tabs, tab groups, favorites, PDFs, screenshots, highlighted page elements, and local files can all be dropped into an AI conversation with the @ anything shortcut, and the agent reads, plans, and runs. The browser ships with Agent Mode, which can create documents and webpages, run deep research, and automate web operations. A multi-agent system loads specialist agents — Research, Operator, Writer, and Analyst — each equipped with the right Skills. Tabbit offers 2000 Agentic Skills covering the top 100 daily-use sites such as YouTube, ChatGPT, Substack, Papers, Reddit, GitHub, and Gmail, and users can build their own skills from scripts or saved agent workflows. Model access is a headline feature: GPT, Claude, Gemini, Grok, DeepSeek, Kimi, Qwen, GLM, Doubao, and MiniMax are all available, with new state-of-the-art models added within 12 hours of launch. Prompts go directly to the provider the user selects, routed through compliant servers in Singapore or the user's region. Everyday browsing features include a context-aware omnibox (browse, chat, search, or agent mode), smart tab grouping, vertical tabs, favorites with full-page saving and hover summaries, multilingual webpage translation, cross-device sync of favorites, passwords, and conversations, one-click import from Chrome, Safari, or Edge, and background updates. Recent releases add webpage generation and one-click publishing, scheduled tasks, pinned chats, address-bar search-engine switching, and desktop pets. The company reports 107,763 users across 20+ countries, with testimonials from podcast hosts, tech bloggers, and startup founders who made Tabbit their default browser. Privacy is a stated principle: highlights, chats, and saved pages stay on the device, and Tabbit says it never sells data, trains on user reads, or decides what users see.

Who is Tabbit for?
Tabbit is built for anyone who lives in a browser and wishes the AI were already part of it — researchers, students, content creators, podcasters, founders, and knowledge workers who juggle dozens of tabs, PDFs, and bookmarks every day. Researchers and students can feed papers, lecture recordings, and notes to the AI and get study aids like Anki flashcards or literature summaries. Podcasters and media creators — like the podcast host quoted on the site who sifts through nearly a million words before each episode — use Tabbit to collect, classify, and integrate source material into show prep. Independent AI creators, tech bloggers, and startup founders use it as a default-browser companion for reading, writing, and producing content. The product also targets people who want automation without leaving the browser: shopping research, deep-research reports, web crawling, and document generation can all be handed to Agent Mode. Multilingual readers benefit from built-in webpage translation and word explanations, and heavy tab users get smart tab grouping plus the ability to chat with tab groups as a knowledge base. It is equally suited to privacy-conscious users, since highlights, chats, and saved pages stay on the machine and prompts go directly to the model provider the user picks. Because the browser is free forever and the Standard plan's 10x AI allowance costs nothing if you set Tabbit as your default browser, it is an easy experiment for anyone curious about AI-native browsing — no payment required to try it.
