## 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

## Siket

Siket is designed around a simple idea: your browser is already open all day, so the workspace should live there. Installing the extension turns your new tab into a productivity dashboard and adds a floating side panel you can summon on any page. The layout is deliberately quiet — no streak counters, no gamified ceremony — so the tool steps back until you reach for it.

The task system is flexible but structured. Everything you capture lands in an Inbox; what you commit to today moves to Today; everything else waits in Next week, project lists, or personal lists. You can view the same list as a list, board, table, or calendar using keys 1–4, and start from ready-made templates for weekly reviews, project kickoffs, or deep-work blocks. A focus timer, tab sessions, notes, and bookmarks round out the daily loop.

On top of that sits an AI agent that plans, prioritizes, summarizes, and drafts. It also connects to tools you already use — Google Calendar, Gmail, Notion, Slack, GitHub, Linear, Todoist, Drive, and others — so planning can draw on real commitments. Payments run through Stripe, and the team states that your data stays yours with secure sessions and real account deletion.

**Pricing & Plans:** Siket has a permanent Free plan with no card required, covering the full workspace: lists, all four views, templates, due dates, themes, and cross-device sync. Paid Pro and Advanced tiers add more capacity and priority support, billed monthly or yearly through Stripe. You can cancel anytime and delete your account from Settings.

- **Four task views:** One list, four ways to see it. Switch between list, board, table, and calendar with number keys 1–4 without moving a single task.
- **Tab sessions:** Save a research trail — a launch, a bug hunt, a reading list — as a tab session and restore the whole set with one click instead of rebuilding bookmarks.
- **Inbox, Today and projects:** Tasks live in Inbox, Today, Next week, project lists, and personal lists. Details stay folded inside each task until you open it, keeping the list short.
- **Focus timer and command palette:** A quiet Pomodoro-style focus timer and a keyboard-first command palette keep deep work moving without reaching for the mouse.
- **Built-in AI agent:** An AI agent inside the workspace plans your day, prioritizes work, summarizes feedback, and drafts copy. Tag context with @context to scope what it reads.
- **Side panel and web capture:** A floating panel on any page in Chrome, Edge, and Brave lets you save pages to your inbox, capture notes with a backlink, or start a timer.

**Strengths:** Replaces a pile of tabs and standalone apps with one new tab workspace; Keyboard-first design with a command palette and number-key view switching; Free tier is genuinely usable with no card and no time limit; Floating side panel captures notes and pages on any website

**Limitations:** Best experienced in Chromium-based browsers; other browsers have limited support; AI agent quality depends on how clearly you state the task; Task capacity and extra AI automation sit behind paid tiers; No native mobile app — it runs through the browser, though cross-device sync works
