## ATO - AI Tab Organizer

ATO (AI Tab Organizer) tackles the familiar problem of dozens of open tabs with two complementary ideas: automation and visualisation. On the automation side, the extension reads page content and clusters tabs into meaningful groups — Research, Shopping, Finance, Work and so on — or sorts them by when you last used them, by predicted frequency of next use, or by topics you define yourself. A dynamic mode groups new tabs the moment they open, so the workspace stays tidy without manual effort.

The visualisation side is the Tab Observer, a full-screen command centre where each Chrome window becomes a "Space" and each tab group a "Planet" whose size grows with the number of tabs it holds. Individual tabs orbit as "Stars", and you can drag and drop them between planets, marquee-select dozens at once, hover for live page previews, and teleport tabs between windows. It is an unusual, game-like take on window management that makes bulk organisation feel fast rather than tedious.

Everyday housekeeping is covered too: duplicate tab detection, instant cross-window search, and custom tab renaming. The free tier includes all organisation methods plus 30 AI tokens that refill monthly; ATO Pro removes the token cap, unlocks the full Tab Observer and adds dynamic auto-organisation. Token management and Pro upgrades require a secure sign-in.

**Pricing & Plans:** ATO has a free tier that includes the full organisation toolbox and 30 AI tokens refilled every month at no cost. ATO Pro removes the token limit, unlocks the complete Tab Observer, adds dynamic auto-organisation and premium support; upgrades are handled in-app or via the vendor's website. Check atobase.app for current Pro pricing.

- **AI Semantic Grouping:** ATO reads page content and clusters tabs into meaningful categories such as Research, Shopping, Finance or Work.
- **Multiple Sorting Modes:** Organise by category, last access, AI-predicted frequency of use, or custom topics you define yourself.
- **Dynamic Auto-Organising:** Enable on-the-fly mode and every newly opened tab is grouped the moment it appears.
- **Tab Observer Universe:** A visual command centre where windows are Spaces, groups are Planets and tabs orbit as Stars, with drag-and-drop and marquee multi-select.
- **Duplicate Cleaning and Instant Search:** Find and close redundant tabs to free memory, and locate any tab across any window with a lightning-fast search box.

**Strengths:** Free tier is genuinely usable, with all organisation methods and monthly token refills; Four distinct AI organisation strategies cover semantic, temporal, predictive and custom needs; The Tab Observer's visual universe makes bulk tab moves faster than list-based managers; Solid 4.5 rating and active version history on the Chrome Web Store

**Limitations:** Free plan caps AI organisation at 30 tokens per month, which heavy users will exhaust; Full Tab Observer access and dynamic auto-organising are locked behind Pro; Token management and Pro upgrades require creating an account and signing in

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
