An Al-powered vertical tabs manager in your side panel.
An alternative to Arcโs Sidebar and Edgeโs Vertical Tabs โ now upgraded with a built-in AI assistant.
Side Space gives you complete control over your browsing experience with powerful vertical tab management and Side Copilot, an AI that helps you research, organize, and automate your workflow directly from the side panel.
๐ How do vertical tabs work?
When vertical tabs are enabled, your open tabs are moved from the top of the browser window to the left side panel. This layout stacks tabs vertically instead of horizontally, giving you more space, better visibility, and easier navigationโespecially when working with many tabs.

๐ค Introducing Side Copilot โ Your AI Assistant in the Side Panel
Side Copilot brings AI directly into your browsing workflow:
Just open AI Chat in the extension and start talking to your browser โ it does the rest.
Node.js Side SpaceSide Space's answer:
Side Space combines powerful vertical tab management with an integrated AI assistant, that's something no other browser extension offers.
Instead of choosing between a better tab manager or an AI browser, Side Space gives you both in one clean side panel.
Side Space's answer:
I am the kind of person who always ends up with too many tabs, too many windows, and no idea where that one page I read yesterday has gone. I tried a bunch of the new AI browsers, but they all felt like replacements for tools I already rely on. I didnโt want a new browser. I just wanted my existing one to feel less chaotic.
So I built Side Copilot for myself first. It helps me manage tabs, jump between windows, find stuff I opened days ago, and generally clean up the mess I constantly create. The thing that changed everything for me was giving it the ability to understand natural commands. I can tell it to group my research tabs or bring back an article from last week and it actually does it. It also has a simple chat mode for quick summaries or translating a page on the spot.
I realized it solved a real problem for me, so I decided to make Side Copilot completely free. Iโm curious how other heavy browser users feel about this. Would an assistant like this make your browsing less stressful?
Side Space's answer:
Most AI tools only analyze text. Side Copilot controls your tabs, windows, history, and pages using real browser APIs. You can research, summarize, organize, open sites, perform searches, restore sessions, and automate actions โ all with natural language.
You donโt need to switch to Arc or Edge. Side Space turns Chromeโs side panel into a clean vertical tabs system with:
Drag-and-drop tab & group management
Fuzzy search
Memory-saving tab suspension
Saved spaces & session restore
Cloud sync
Dark mode
You get a modern browser experience without leaving Chrome.
Chat Mode โ instant content analysis (summary, translation, extraction, quick answers)
Agent Mode โ deep automation (organize tabs, clean up windows, run research workflows)
Fast when you need speed, powerful when you need automation.
Side Copilot isnโt โjust another chatbot.โ It uses more than 20 AI MCP tools built on Chrome Extension APIs:
Tab tools: create, close, group, move
Window tools: tile, arrange, focus
History tools: analyze, find, reopen past pages
Page interaction tools: scroll, navigate, search, capture screenshots
Session tools: restore recently closed tabs/windows
This gives Side Space automation capabilities even AI browsers donโt have.
Side Space's answer:
Side Space is designed for anyone who works, researches, or creates directly in the browser โ especially those who manage dozens of tabs every day. If the browser is your workspace, this is for you.
Productivity-Driven Professionals
Marketers, PMs, developers, designers, analysts โ anyone who needs a smarter, faster way to organize tabs, windows, and workflows.
Power Browsers with Endless Tabs
For users juggling 20โ200+ tabs across multiple windows. Side Space brings structure, clarity, and smart automation without forcing you to switch browsers.
AI-Forward Users
If you want to control your browser with natural language, automate tasks, and let Side Copilot handle the heavy lifting, this is your perfect tool.
Researchers & Knowledge Workers
Students, academics, journalists, content creators, and anyone who collects and analyzes information online. Summarize, extract, search, and research pages instantly.
People Who Want Arc/Edge-Style Features โ But in Chrome
Enjoy a vertical tabs manager, powerful side panel, and full AI assistant experience without giving up the browser you already love.

Node >= 22 or higher installed on their local development machine. - Source: dev.to / about 2 months ago
TypeScript / Node.js: Excellent for building asynchronous backend systems that must stream text data smoothly to thousands of users simultaneously. - Source: dev.to / about 2 months ago
Because Node.js operates on a single-threaded asynchronous runtime, it is inherently vulnerable to processes that hog the CPU for too long. I absolutely cringe whenever I see developers blindly copy-pasting complex regular expressions from StackOverflow without actually testing their performance impact. - Source: dev.to / about 2 months ago
This tutorial walks you through setting up a simple Docker Compose project that serves two Node web servers over HTTPS using Caddy as a reverse proxy. You will learn how to use mkcert to generate wildcard certificates and the minimal configuration needed in the Caddyfile and docker-compose.yml to get it all working. - Source: dev.to / 3 months ago
Node.js: This is required for Hardhat. You can check if your terminal has it installed by running node -v. It will show a version number, if it is already available. If not, download the LTS version from https://nodejs.org/en, install it, then reopen your terminal and recheck to confirm successful installation. - Source: dev.to / 4 months ago
