## Quetta Browser

Quetta is a web browser that positions itself around two ideas: watching and saving web video without interruptions, and keeping everyday browsing private. Built for mobile first, with Android and iOS apps plus a PC extension, it combines supported MP4/WebM and HLS/M3U8 downloads, an enhanced player with picture-in-picture, background audio, captions and playback-speed controls, and built-in ad and tracker blocking in a single app.

A standout feature is extension support on Android: Quetta can install and run many extensions from the Chrome Web Store and Microsoft Edge Add-ons, which is unusual for a mobile browser. Compatibility varies because some extensions were designed for desktop layouts, so Quetta recommends checking that each add-on's popup and main action still work on a phone.

Privacy controls help limit cross-site trackers and fingerprinting scripts, and give users tools to review browsing data and manage site permissions. Quetta also markets an "AI⁺ Ad Blocker" as part of its blocking stack. The browser is free to use; the site describes it as a downloadable product rather than a subscription service.

**Pricing & Plans:** Free to download and use. No paid subscription is advertised on the official site; the product is distributed as an app for Android and iOS with a PC extension.

- **Built-in ad and tracker blocking:** Quetta checks pages for supported ad, pop-up and tracking patterns and blocks matching requests or elements, with the option to review activity and adjust protection when a site misbehaves.
- **Supported video downloads:** When compatible media is detected, you can save MP4 or WebM files and supported M3U8/HLS streams directly from the page without switching to a separate downloader.
- **Enhanced video player:** Picture-in-picture, background audio, playback speed, captions and casting help adapt supported videos to how you actually watch on mobile.
- **Extensions on Android:** Install, enable, disable or remove many extensions from the Chrome Web Store and Edge Add-ons inside the Android browser, giving mobile users desktop-style customization.
- **Privacy Guard controls:** Tools to block cross-site tracking requests and known fingerprinting scripts, plus settings to review browsing data and manage site permissions.

**Strengths:** Combines ad blocking, video downloading and an enhanced player in one free browser; Rare Android extension support from Chrome Web Store and Edge Add-ons; Strong privacy controls against trackers and fingerprinting; Video-focused player features like picture-in-picture and background audio

**Limitations:** Download and extension compatibility varies a lot by website and device; Some Android extensions behave differently because they were built for desktop; Feature depth may be excessive for users who just want a plain browser

## 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
