An Al-powered vertical tabs manager in your side panel.

An alternative to Arc’s Sidebar and Edge’s Vertical Tabs — 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.

🚀 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 navigation—especially when working with many tabs.

Features

  • ⚡️ Vertical Tabs Panel — Manage tabs and tab groups efficiently in a clean, space-saving sidebar.
  • 🗂️ Save, restore, and reorder tabs or tab groups with intuitive drag-and-drop.
  • 🔄 Side-by-side layout that keeps all your open tabs visible at a glance.
  • 🔍 Fuzzy search to instantly find the tab you're looking for.
  • 🧹 Suspend tabs to save memory and keep your browser running smoothly.
  • ☁️ Cloud sync (cross-browser) with a single login.
  • 🌛 Dark Mode support.
  • 💾 Space Backup Solutions

    • 📑 Export sessions as JSON
    • ☁️ Sync to the cloud via login
  • AI-powered Tab Grouping for automatically organizing related tabs.

  • 🔗 Group Guardian automatically groups tabs based on URL patterns.

🤖 Introducing Side Copilot — Your AI Assistant in the Side Panel

Side Copilot brings AI directly into your browsing workflow:

  • Ask questions about the page you're viewing
  • Research topics with auto-opened results
  • Summarize long articles instantly
  • Organize tabs and windows through natural language commands
  • Trigger automated actions across your browser

Just open AI Chat in the extension and start talking to your browser — it does the rest.

Questions & Answers

As answered by people managing WordPress and Side Space.

What makes your product unique?

Side 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.

What's the story behind your product?

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 didn’t 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. I’m curious how other heavy browser users feel about this. Would an assistant like this make your browsing less stressful?

Why should a person choose your product over its competitors?

Side Space's answer:

  1. The world’s first AI assistant built for your tabs

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 — all with natural language.

  1. A true vertical tabs manager, not a browser replacement

You don’t need to switch to Arc or Edge. Side Space turns Chrome’s 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.

  1. Dual AI modes for different tasks

Chat Mode → instant content analysis (summary, translation, extraction, quick answers)

Agent Mode → deep automation (organize tabs, clean up windows, run research workflows)

Fast when you need speed, powerful when you need automation.

  1. Page, tab, window, and history tools powered by real browser capabilities

Side Copilot isn’t “just another chatbot.” 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 don’t have.

How would you describe the primary audience of your product?

Side Space's answer:

Side Space is designed for anyone who works, researches, or creates directly in the browser — 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 — anyone who needs a smarter, faster way to organize tabs, windows, and workflows.

Power Browsers with Endless Tabs

For users juggling 20–200+ 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 — But in Chrome

Enjoy a vertical tabs manager, powerful side panel, and full AI assistant experience without giving up the browser you already love.
