## 概要

Side Space is a browser extension that replaces the usual horizontal tab strip with a vertical sidebar, so you can read tab titles in full and keep dozens of open pages organised. It groups tabs automatically with AI-assisted logic, supports nesting and drag-and-drop, and works across Chrome, Brave and Edge. A one-time lifetime license is sold through the Side Space Store on Lemon Squeezy.

## 料金とプラン

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.

## 主な機能と特長

- **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.

## 主なユースケース

- **Manage research-heavy sessions (Researchers and analysts):** Keep dozens of reference pages open during a project and let AI grouping cluster them by topic so nothing gets lost.
- **Organise project tabs visually (Developers and freelancers):** Separate client work into nested groups and switch between them quickly without hunting through a crowded top bar.
- **Reduce tab overload (Everyday browser users):** Read full page titles in a sidebar instead of guessing from truncated tabs, which helps with accessibility and speed.
- **Pay once, use across browsers (Lifetime-license buyers):** Buy a single lifetime license in one currency and install the extension on the Chromium browsers you already run.

## 強み

- 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
- One-time lifetime license instead of an ongoing subscription

## 制約・デメリット

- 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
