Hey everyone! I'm Robert, the founder of Side Space.
We’re excited to introduce Side Space 2.0, our biggest update ever, now powered by our Side Copilot, an AI assistant built directly into your browser’s side panel and helps you browse smarter.
Our Journey 🚀
Just last year, we launched Side Space v1 with a simple vision: to make your browser's side panel truly useful just like Arc browser’s sidebar does. What happened next blew us away.
Today, we're thrilled to share that over 10,000 users have joined us on this journey! 🎉 You've made Side Space part of your daily workflow, and your feedback has been incredible.
But we didn't stop there. We listened to every suggestion, every feature request, and every idea you shared. That's why we're bringing you Side Copilot, a powerful assistant that turn your words into action, transforms how you browse, research, and work online.
This isn't just an update. It's a complete reimagining of what Side Space can do for you.
With Side Copilot, you can now:
🚀 Chat with your browser to organize tabs & windows automatically
💬 Summarize, translate, explain or extract content of your page
🤖 Run automated actions like search, research or restore by using natural language
🔑 Use BYOK (Bring Your Own Key) for more control, security, and privacy
⚡ Use shortcuts to trigger commands instantly
…and many more magical ways to upgrade your browsing experience are waiting for you to discover.
Everything happens in the side panel, no new AI browser needed.
We’d love to hear what you think and how we can make Side Copilot even better.
PS: Side Copilot is free to try for everyone during Black Friday and Cyber Monday. Have fun! 😁
@robert_shaw_p I already love Side Space and one of your early adopters from last November. Unless I have missed them, I am wondering about a few features:
a feature to sync tabs/tab groups across multiple browsers/devices
a sleep tab feature to save all or specific open tabs to a group
a snooze tabs feature
I currently
Organize/group tabs with Side Space
Collect/close tabs with Keptab
Export Keptab tab groups as JSON and import it to the Keptab extenstion in other browsers and devices to keep everything in sync.
I also use Dormy by OrriGo to snooze specific tabs that I want to pop-up at a specified time.
Steps 1, 2, & 4 are very simple and work fine, but step 3 adds complexity and more manual effort. I would love it if I could do all of this in Side Space alone!!

@just_s Thank you so much for being an early adopter, really appreciate your support and the thoughtful feedback! A couple of clarifications:
Side Space already has sync built in, and it’s completely free. Once you’re logged in, your spaces (including tabs and tab groups) automatically sync across browsers and devices. Since we already support this, you no longer need to export JSON files to keep your data in sync across devices or browsers, it all happens automatically. And thank you for the reminder, you’re right that we haven’t made this feature very visible, which can make it seem like syncing isn’t there. We’ll be adding a clearer cloud-sync indicator soon.
About sleep/snooze tab features: our goal is to help users organize, categorize, and save the useful tabs, not to save every inactive tab and create clutter. In our experience, most unconsciously saved tabs end up forgotten and become noise rather than something meaningful.
Thanks again for the thoughtful feedback, it truly means a lot!

This is a great tool to have for your Chrome browser (I only use this one currently). Love what you are doing

@chilarai That's why you do not need another AI Browser.
Arc-like sidebar UI + AI Assistant for your Tabs.

Congrats on the launch Robert!

Absolutely love this! The vertical tab manager alone is super useful, but pairing it with Side Copilot for natural-language organization is next-level. This genuinely makes multi-tab research feel effortless.

@akarshjha03 Thank you so much!
We’re thrilled to hear that Side Copilot is making multi-tab research easier and more enjoyable. It means a lot to us that you’re finding the vertical tabs + AI workflow helpful!

Hey all! 👋
I’m part of the team behind Side Space, and we just launched our biggest update ever.
If you’ve ever wished your current browser like Chrome, Edge, Brave, Zen or Firefox had a smarter sidebar or wanted AI to actually help with your tabs, windows, and research, give it a try!
Always happy to chat, answer questions, or hear what features you want next! 💛
Great idea, congrats !
Do you plan to address B2B customers (with additional security) ?
Side Space
@rolphi Thank you! Really appreciate the support!
At the moment, we’re focused on improving the core experience for individual users, so we don’t have plans for B2B features yet. That said, we’re keeping an eye on the demand, and if more teams ask for it, we’re open to exploring it in the future.
