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.

Analysis of Side Space

Overall verdict

Why this product is good

  • Helps organize and group browser tabs into dedicated spaces, reducing clutter
  • Improves productivity by allowing quick switching between different projects or contexts
  • Offers a clean, intuitive interface that's easy to adopt

  • Remote workers seeking better digital workspace organization
  • Anyone prone to tab overload looking to streamline their browsing

Analysis of Threadstr

Overall verdict

  • I don't have verified, up-to-date information about Threadstr (threadstr.co) specifically, so I can't confirm its quality, pricing, or feature set with confidence. Based on the name, it appears to be a tool related to creating or managing threads (likely for platforms like X/Twitter), but you should verify current reviews, pricing, and features directly on their website or through independent user reviews before deciding.

Why this product is good

  • Unable to verify specific features or user satisfaction due to lack of reliable data on this product
  • If it follows typical thread-writing tool patterns, potential benefits might include easier thread formatting, scheduling, and analytics
  • Always check recent user reviews on sites like Trustpilot, G2, or Twitter/X itself for real feedback
  • Look for a free trial or demo to test functionality firsthand before committing

Recommended for

  • Cannot confidently recommend without verified information
  • Potentially useful for social media content creators or marketers if the tool delivers on typical thread-creation features
  • Best suited for users willing to test it themselves and verify claims independently

Questions & Answers

As answered by people managing Side Space and Threadstr.

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 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?

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.

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 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 20โ€“200+ tabs across multiple windows. Side Space brings structure, clarity, and smart automation without forcing you to switch browsers.

AI-Forward Users
