## QuickDic AI

QuickDic AI targets the friction of reading online: you hit an unfamiliar term, want extra context on a claim, or need a quick alternative perspective, and the usual answer is to open a new tab, paste the text into a chatbot, and lose your place. The extension collapses that loop. Once installed it places a subtle floating button in the middle of every page and also responds to a double-click on selected text, then renders its AI response in an overlay on top of the current site. You keep scrolling, keep the page context, and get an answer where you already are.

The feature that sets it apart from a bare lookup tool is the way it presents answers. Rather than a single definition, QuickDic AI aims to give a multi-dimensional view, including related or alternative questions you might not have thought to ask. That framing is aimed at researchers, students and curious readers who want breadth rather than a one-line result, and it works across social feeds, shopping listings, documentation and general articles.

QuickDic AI is a free listing in the Chrome Web Store from developer QIO Enterprises LTD, currently at version 1.0.6 and last updated in mid-2023, with an English-language interface. Setup is a single click from the store: add the extension, grant its permissions, and the on-page button appears on subsequent pages. There is no account or subscription gate described for using it, and the store listing states the data it handles is not sold to third parties.

**Pricing & Plans:** Listed as a free extension in the Chrome Web Store, with no paid tier described in the listing.

- **Double-click to query:** Select or double-click text on any page and the extension fires an AI query on your behalf, returning an answer in an overlay without a trip to a chat app.
- **Multi-angle answers:** Responses go beyond a single definition and suggest related or alternative questions, giving you several ways into the same subject.
- **Invisible on-page button:** A subtle floating button sits in the centre of each page so the assistant is one click away on social feeds, shops and long articles alike.
- **Stays out of the way:** The overlay renders on top of the current page, so you never lose your scroll position, tab or reading flow.
- **Works across site types:** Designed for social media platforms, eCommerce listings and general web content rather than a single supported destination.

**Strengths:** Eliminates tab-switching by answering inside the current page; Encourages broader understanding by suggesting related questions, not just one definition; Free to install and try with no account described; Works on social, shopping and general sites rather than one platform

**Limitations:** Simple overlay and word-lookup utilities competes with stronger, more actively maintained extensions; Store page shows no user ratings and no updates since 2023, so quality signals are thin; The listing declares handling of personally identifiable information and location data, which some users will weigh before installing

## 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
