If you work in SEO, marketing, or really any job that involves a computer, your browser is a warzone. My tab bar often looks like a graveyard of good intentions. One tab for Google Analytics, five for keyword research, three for that competitor analysis I swore I'd finish, a YouTube video on how to fix a leaky faucet, and twelve different versions of the same Google Doc. It’s a mess.
We’ve all been there. That moment you look up and see a chaotic, indecipherable line of favicons staring back, each one a silent monument to a task started but not finished. For years, I’ve been on a quest for the perfect tab manager. I’ve tried bookmarking everything (never look at them again), using other extensions (some good, some clunky), and even just surrendering to the chaos. Nothing really stuck.
Then I stumbled upon Side Space. The promise? An AI-powered vertical tabs manager. Vertical tabs aren't new, of course. Browsers like Edge have been pushing them for a while. But adding AI to the mix? That got my attention. Skeptical, but intrigued, I decided to give it a spin.
So What Exactly Is Side Space?
At its core, Side Space is a browser extension (for Chrome, Brave, Edge, etc.) that moves your chaotic horizontal tab bar into a neat, organized panel on the side of your screen. Simple enough. But thinking of it as just a list of tabs is missing the point entirely.
The real magic is in its core philosophy: Spaces.
Instead of one endless list, Side Space lets you create separate, self-contained… well, spaces. Think of them as different workbenches. You can have a 'Work' space with all your SEO tools and documents, a 'Personal' space for your shopping and social media, and a 'Project X' space for that deep-dive research rabbit hole you're currently lost in. Switching between them is instant, and it completely changes how you mentally approach your work. It's not just tidying up; it's compartmentalizing your brain. It’s brilliant.

The Magic Ingredient is AI Tab Grouping
Okay, here’s the part that made my inner tech geek raise an eyebrow. “AI-powered Tab Grouping.” In 2024, slapping “AI” on anything is a marketing go-to. So, does it actually work, or is it just fluff? I opened about 30 random tabs—a mix of articles, social media, dev tools, and Google Sheets—and hit the 'Group by AI' button.
And… it was surprisingly good. It wasn't perfect, mind you. It once tried to group an article about PPC trends with my Amazon order history (maybe it knows something about my shopping habits I don't?). But for the most part, it correctly identified articles, tools, and social sites, and bundled them up neatly. I'd say its success rate is a solid 85-90%. It’s less of a mind-reading psychic and more of a really, really efficient intern who just needs a tiny bit of supervision. For tidying up a chaotic session in seconds, it’s a genuine time-saver.
Living in Different 'Spaces'
After a week of using sidespace, the Spaces feature has become indispensable. My workflow has completely changed. I start my day, open my 'Morning Routine' space, which has my email, calendar, and news sites. Then, I click over to my 'Main Work' space, and all my project management tools, analytics dashboards, and client folders are ready to go. No more hunting for that one specific tab I know I opened yesterday.
If I get a message from a friend with a link, I don't open it in my work context anymore. I pop over to my 'Personal' space, open it there, and keep my work environment clean. This little act of digital hygiene has had a surprising effect on my focus. It reduces the mental load of context switching because the tool is doing it for me.
Key Features That Actually Matter
Side Space is packed with features, but a few stand out as genuinely useful day-to-day. The Auto Sync and Save/Restore Tab Groups are the unsung heroes. Remember that feeling of pure panic when your browser crashes and you lose 50 tabs of crucial research? Gone. It’s all saved in your space, ready to be restored. I can shut down my work PC and open the exact same setup on my laptop later. It just works.
Another one I love is Suspend Tabs. As someone whose laptop fan often sounds like it’s preparing for takeoff, being able to temporarily put a whole space to sleep to free up memory is a godsend. Your RAM will thank you. Little things, like the built-in search, de-duplication, and the ability to pin key tabs, round out the experience, making it feel polished and thoughtfully designed.
The Good, The Bad, and The AI
No tool is perfect, right? Here’s my honest breakdown of where Side Space shines and where it has room to grow.
| What I Loved (The Pros) | What Could Be Better (The Cons) |
|---|---|
| The vertical layout and 'Spaces' are a revelation for organization and focus. | The free version is limited to 5 spaces, which you can fill up surprisingly fast. |
| The AI grouping is genuinely helpful for quick clean-ups, saving a lot of manual dragging and dropping. | You have to log in with a Google or GitHub account for cloud sync, which might be a turn-off for the super privacy-focused. |
| The generous free plan lets you properly test it out. And the lifetime deal is fantastic value. | The AI can occasionally miscategorize a tab, but it's easy to manually correct. |
| Features like tab suspension and auto-sync provide real peace of mind and performance boosts. | It takes a little getting used to if you've been a top-tab user for decades. |
Honestly, the cons are pretty minor in the grand scheme of things. The 5-space limit on the free plan is the most noticeable one, but it’s more of a gentle nudge towards the paid plan than a crippling restriction. And let's be real, the AI not being 100% perfect is kind of expected. It's a tool to assist you, not replace you.
Let's Talk About The Price
This is often the dealbreaker, but Side Space gets it right. They have a simple, two-tier approach that I really appreciate. No confusing subscription models or hidden fees.
Free Plan
$0
You get up to 5 spaces, AI grouping for 1000 URLs, and all the core tab management features. It’s more than enough to see if it fits your workflow.
Lifetime Plan
$39 (one-time payment)
This is the real deal. Unlimited everything. Spaces, AI grouping, premium support, and all future updates for life. For what it does, this is an absolute bargain.
A one-time payment of $39? In an age where every other app wants $10/month forever, this feels like a breath of fresh air. It’s less than the cost of a nice dinner out, and it brings a daily dose of sanity to my workflow. For me, that’s a no-brainer. They also offer a 7-day money-back guarantee, so the risk is basically zero.
My Final Verdict on Side Space
So, is Side Space the holy grail of tab management I've been searching for? It's the closest I've ever come. It's not just a utility; it's a tool that has genuinely improved my focus and organization.
Who is this for? If you're a tab hoarder, a researcher, a developer, a marketer, or anyone who juggles multiple projects within a browser, you owe it to yourself to try this. It will feel like you’ve suddenly decluttered your entire digital office.
Who might not need it? Well, if you're one of those mythical creatures who only ever has three tabs open at once… first of all, how do you do it? And second, you probably don't need this. For the rest of us mortals, Side Space has earned its permanent spot on my browser extension bar. It's a small tool that makes a huge difference.
Frequently Asked Questions
- How does Side Space actually work?
- It's a browser extension that creates a new panel on the side of your window. This panel becomes your new tab manager, where you can group tabs into different 'Spaces' to keep things organized. It's much easier to see and manage than the traditional row of tabs at the top.
- Do I really have to sign in?
- You only need to sign in with a Google or GitHub account if you want to use the cloud sync feature, which keeps your spaces consistent across different computers. If you only use one machine, you can use it without signing in, but the sync is a pretty great feature to have.
- Is the lifetime deal a one-time thing?
- Yes! You pay the $39 once and you get all the premium features, plus all future updates, forever. It's not a subscription, which is a huge plus in my book.
- How generous is the free version really?
- It's very generous. With 5 spaces and 1000 AI grouping actions, you can do a lot. It's designed to be fully functional so you can decide if you like the workflow before even thinking about paying.
- What if I buy it and hate it?
- They have a 7-day money-back guarantee. If you upgrade to the Lifetime plan and decide it's not for you within a week, you can get a full refund. So there’s no risk in trying out the full experience.
