As answered by people managing Side Space and Linear.
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.
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?
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 — all with natural language.
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.
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.
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.
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

Ans: Usually not! Coding work moves fast and differently than marketing or sales work. Many startups use Linear for code and something simpler, like Asana or ClickUp, for the rest of the team.
