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.
VS Code 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

Visual Studio Code, a code editor created by Microsoft, was first introduced on April 29, 2015, at the Build conference. - Source: dev.to / about 13 hours ago
The step up from there is an editor with a built-in agent like Cursor, Google Antigravity, Windsurf, or VS Code with a coding extension. These are code editors with an AI agent living inside them, and the difference is the responsible party for getting things from place to place. Instead of the software creator shuttling code between windows, the AI agent edits the project files directly and runs the GitHub and... - Source: dev.to / 15 days ago
For IDE-heavy teams, BYOK (bring your own key) can be interesting, no matter whether you live in WebStorm or VS Code. On the JetBrains side, the JetBrains AI plans and Junie BYOK docs allow it, and most VS Code AI extensions offer the same idea: keep the IDE, connect provider keys, pay the provider. - Source: dev.to / about 1 month ago
Option 1: Raw editing in IDE. You open the .md file in VS Code or whatever you use. Syntax highlighting shows you the structure. Maybe you toggle a preview pane. This works for quick edits but becomes painful for anything involving tables, diagrams, or complex formatting. - Source: dev.to / about 1 month ago
You'll need Python 3.8+ and pip for the quickstart, with venv recommended for isolation. Install the requests library for HTTP calls. VS Code with the Python extension works well as an editor, though PyCharm or Sublime Text work equally well. You'll also need a free Foxit developer account. - Source: dev.to / about 1 month ago
