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

An alternative to Arcโ€™s Sidebar and Edgeโ€™s 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.

๐Ÿš€ 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 navigationโ€”especially when working with many tabs.

Questions & Answers

As answered by people managing Side Space and nettest.in.

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.

nettest.in's answer:

Nettest.in offers a revolutionary solution to internet speed woes. With HTML5-based real-time speed tests and YouTube quality checks

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 didnโ€™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. Iโ€™m curious how other heavy browser users feel about this. Would an assistant like this make your browsing less stressful?

nettest.in's answer:

Nettest.in likely emerged from a recognition of the widespread frustration with slow internet speeds and unreliable connections. Its founders may have been motivated by a desire to provide a solution to this problem by creating a platform that offers accurate and real-time internet speed tests and quality checks. Perhaps they envisioned a user-friendly interface accessible across various browsers, prioritizing reliability, accuracy, and user privacy.

Why should a person choose your product over its competitors?

Side Space's answer

  1. The worldโ€™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 โ€” all with natural language.

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

You donโ€™t need to switch to Arc or Edge. Side Space turns Chromeโ€™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 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.

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

Side Copilot isnโ€™t โ€œjust 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 donโ€™t have.

nettest.in's answer:

its user-friendly interface and compatibility across all browsers offer a hassle-free experience for everyone. Additionally, nettest.in prioritizes user privacy by supporting the Tor project, catering to individuals who value anonymity online. Lastly, its commitment to reliability, accuracy, and continuous innovation, powered by cutting-edge technologies, makes it a preferred choice for millions seeking to optimize their internet experience.
