## 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

## TabMate

TabMate is a free Chrome extension built around one clear mission: solving the “too many tabs” problem with AI. Instead of you manually dragging tabs into groups, it looks at the content of the pages you have open and automatically sorts them into topic groups, so everything about a given subject ends up in one place. It is distributed on the Chrome Web Store and installs in a click.

Two features give you control over the automation. Smart Groups let you define custom topics that fine-tune how TabMate classifies pages, which is useful when you want a specific kind of page filed in a specific way. Locked Groups let you keep a hand-organised collection exactly where you put it, so the AI leaves it alone. The extension is also keyboard-first: most actions can be carried out without reaching for the mouse, which matters when you are sorting tabs quickly.

TabMate is openly labelled as experimental and currently in Beta, and the developer invites feedback and suggestions through the r/tabmate subreddit. That means you should expect an evolving tool rather than a finished product, and it is best suited to users who are comfortable shaping a young extension. It is free to use, and because it needs to read tab content, web history and activity to do its job, privacy-conscious users should review its data disclosure in the store listing.

**Pricing & Plans:** TabMate is free. It is a free Chrome Web Store extension currently in Beta, with no paid tier described in its listing.

- **Automatic topic grouping:** TabMate reads the content of each page and sorts tabs on the same topic into a shared group, so related pages sit together.
- **Custom Smart Groups:** Create your own Smart Groups to steer and fine-tune how the extension classifies your tabs.
- **Locked Groups:** Lock a group to organise a collection of tabs manually without the AI rearranging them.
- **Keyboard-first control:** Most actions can be triggered with the keyboard alone, speeding up tab sorting and switching.
- **Free Chrome extension:** Installs straight from the Chrome Web Store and runs in your browser without a separate account or subscription.

**Strengths:** Free Chrome extension with no subscription; Automatic AI grouping removes the need to file tabs by hand; Smart Groups and Locked Groups let you fine-tune or override the AI; Keyboard-first design makes tab management fast

**Limitations:** The extension is in Beta, so behaviour and features may still change; It is experimental by design, so classification accuracy is not always perfect; Requires broad access to tab content, web history and user activity to do its job, which may concern privacy-focused users
