## Side Space

Modern browsers hide most of your work behind a single horizontal strip of shrinking tabs. Side Space takes the opposite approach: it moves the tab list into a vertical sidebar, where titles, favicons and grouping stay legible no matter how many pages you have open. The result is a browser that reads more like a file tree than a stack of postage stamps.

The extension leans on AI-assisted grouping to keep things tidy. Instead of manually dragging every new tab into place, related pages get clustered together, and you can refine the arrangement with nesting and drag-and-drop when you want a specific structure. It is distributed for Chromium-based browsers, with Chrome, Brave and Edge named as supported targets.

Side Space is sold as a one-time lifetime license through the Side Space Store, which is hosted on Lemon Squeezy and currently lists the lifetime license at $79.00, alongside a Subscribe option. That model suits people who keep a lot of tabs open and prefer a single purchase over a recurring fee.

**Pricing & Plans:** Side Space is sold through the Side Space Store on Lemon Squeezy. The storefront currently shows a Side Space Lifetime License at $79.00 as a one-time purchase, and also displays a Subscribe option. Because it is a paid, one-time-license product rather than a metered subscription, there are no per-seat monthly charges advertised on the tracked page.

- **Vertical tab sidebar:** Move your open tabs out of the cramped top bar and into a full-height sidebar where titles and favicons are easy to read.
- **AI-powered tab grouping:** Let the extension cluster related tabs automatically with AI, so research or project sessions stay grouped without manual sorting.
- **Nesting and drag-and-drop:** Nest tabs under parent tabs and drag them between groups to mirror how you actually think about your work.
- **Chrome, Brave and Edge support:** Built for Chromium-based browsers including Chrome, Brave and Edge, so your setup travels across the browsers you already use.
- **One-time lifetime license:** Buy once through the Lemon Squeezy storefront instead of paying a recurring subscription, with a Subscribe option available if you prefer.

**Strengths:** Makes long tab titles fully readable in a vertical sidebar; AI-assisted grouping reduces the manual work of tidying tabs; Nesting and drag-and-drop support flexible personal organisation; Works across Chrome, Brave and Edge

**Limitations:** Lifetime license is a one-time purchase rather than a low monthly plan, which may put off casual users; Only useful if you keep many tabs open; light browser users may not see the benefit; The purchase page is hosted on Lemon Squeezy, so there is no long marketing site with extensive documentation on the tracked URL; Availability depends on stores supporting vertical tabs in Chrome, Brave and Edge

## Tabbit Browser

Tabbit positions itself as a browser rebuilt around AI rather than a browser with an AI sidebar bolted on. The core idea is that the page you have open—plus any tabs, groups, files, or screenshots you reference—already constitutes the context an AI needs, so you should be able to ask a question without copying and pasting anything. Highlighted text, screenshots, and whole pages can be attached to a prompt with a single action.

Beyond conversation, Tabbit includes an agent layer that automates repeated browser work: opening pages, filling forms, and executing multi-step routines you describe in plain language. It also ships a prompt library called 妙招 (smart moves) for saving frequently used instructions and calling them with one click, plus automatic tab grouping that sorts open tabs into a vertical sidebar and summarizes them so research material stays findable.

Tabbit runs on macOS (Apple Silicon and Intel), Windows, iOS, Android, and HarmonyOS, and lets you switch freely among a roster of leading Chinese AI models including DeepSeek, Kimi, GLM, MiniMax, Doubao, Qwen, and LongCat. It also offers one-click migration of bookmarks, history, extensions, and settings from your previous browser. The product is free to use with an optional paid membership tier, and the developer is Beijing Kuxun Interactive Technology.

**Pricing & Plans:** Free to download and use, with an optional membership tier for additional benefits.

- **Context from anything on screen:** Reference tabs, tab groups, local files, highlighted text, whole pages, or screenshots as context with a single @ or one click, so you never copy-paste background material again.
- **Agent task execution:** Describe a routine in plain language and Tabbit's agent opens pages, fills forms, and carries out repetitive operations for you.
- **Multiple AI models, freely switchable:** Choose among several leading models including DeepSeek, Kimi, GLM, MiniMax, Doubao, Qwen, and LongCat depending on the task.
- **Smart tab organization:** Tabs are automatically grouped, categorized, and summarized in a vertical sidebar, making dozens of open research pages manageable.
- **One-click migration:** Import bookmarks, history, extensions, and custom settings from your existing browser to switch without losing your setup.

**Strengths:** AI is integrated as the browser's core model rather than added as an extension; Context referencing with @ removes the copy-paste step entirely; Agent automation handles genuine repetitive work; Free to use across desktop, mobile, and HarmonyOS

**Limitations:** The interface and model lineup are oriented primarily toward Chinese-language users; As a newer browser, its extension ecosystem cannot yet match established browsers; Automatic tab grouping and agent actions require trust in how browsing data is handled
