Not more settings, but a better experience. We don't strive to be a "Swiss Army Knife" with 100+ switches. We focus on building a browser sidebar that is ready out-of-the-box, beautifully elegant, and 100% privacy-secure.

Design Philosophy Arc-like Sidebar: Emphasizes opinionated, optimal defaults. Traditional Sidebars: All-purpose toolboxes. AI Setup Threshold: Zero configuration (built-in local AI). Traditional Sidebars: Requires applying for API keys. Design Aesthetics: Minimalist Arc style & micro-animations. Traditional Sidebars: Focuses on feature density rather than visual appeal, native browser UI. Privacy Protection: 100% offline analysis. Traditional Sidebars: Sends data to third-party APIs. Out-of-the-Box Readiness: Opinionated, best defaults. Traditional Sidebars: 100+ configuration options, steep learning curve. Hover Smart Summary: Pioneering floating highlight generation. Traditional Sidebars: Not supported.

We believe a good tool should exercise restraint, filtering out distractions for you rather than being stuffed with unnecessary switches. Looking for the best alternative to other solutions? vs Workona | vs Toby | vs Standard Vertical Tabs

Reshape your browsing experience We have integrated all the tools you need into one elegant sidebar.

Local AI Smart Organization When you have dozens of tabs open and don't know how to organize them, click a button and the AI will automatically categorize and archive your tabs for you. Most importantly, all computations are performed on your device via Gemini Nano. Data is never uploaded to the cloud. [Example categorizations: YouTube, GitHub, Gmail, StackOverflow, Spotify, Notion, MDN, Netflix, Slack, Vercel, Twitch, Figma classified into Development Resources, Video & Entertainment, Work & Projects]

Silky Smooth Drag-and-Drop Layout We completely blurred the lines between tabs and bookmarks. Drag a tab into a folder, and it becomes a bookmark; drag a bookmark out, and it becomes an active tab.

Canvas-Level Customization Built-in with multiple exquisite theme color schemes, supports custom HSL colors, and even allows you to upload your exclusive background image to create a unique sidebar style.

Reading List Don't let "read later" turn into "read never". A built-in integrated article staging area focuses on information absorption.

Lightweight RSS Subscription Automatically fetches the latest updates from your tracked websites without the need to install additional readers.

Even More Highlights From searching to keyboard controls, every detail is polished. Hover Smart Summary: Hover over a tab for 2 seconds, and the AI automatically generates a one-sentence summary. No more blind clicking. Opinionated Aesthetics: Deeply polished Glassmorphism textures and silky micro-animations for an ultimate browsing quality. Linked Tabs: Open bookmarks directly from the sidebar.
