## Page Copilot

The extension is built around one simple idea: the page you are already reading should be able to answer your questions. Once installed, Page Copilot reads the visible content of the active tab and lets you hold a conversational exchange with it — asking for a short summary, requesting the main takeaways, or digging into a particular section without scrolling back and forth.

It is aimed at people who consume a lot of long-form content: researchers skimming papers, students working through dense material, and professionals who need to extract the essence of an article before a meeting. The extension markets three benefits — saving time on long articles, reinforcing learning by surfacing key insights, and offering an interactive rather than passive reading experience.

The listing is free, currently shows a 5.0 rating from a small handful of reviewers, and is published by an independent developer (dreampulse) who states that no user data is collected or sold. Because it is a browser extension rather than a hosted SaaS platform, there is no account or subscription to manage — you simply install it from the Chrome Web Store and start using it on the pages you visit.

**Pricing & Plans:** Free. Page Copilot is distributed at no cost through the Chrome Web Store as a browser extension, with no published subscription tiers.

- **Interactive page conversations:** Ask questions about the page you are viewing and get answers grounded in that page's content instead of starting a fresh chat elsewhere.
- **Instant summaries:** Generate a concise digest of long articles and complex documents so you can decide quickly whether they deserve a full read.
- **Key point extraction:** Pull out the main arguments, findings and insights from dense material, which makes revision and note-taking far faster.
- **Runs inside Chrome:** Works as a standard extension in the toolbar, so there is no separate app to launch and nothing to configure beyond installing it.

**Strengths:** Completely free with no account or subscription required; Lets you question the page directly instead of copying text into another tool; Very small download footprint and simple toolbar-based workflow; Developer states that no personal data is collected or sold

**Limitations:** Small install base and only a handful of ratings, so long-term reliability is not yet proven at scale; Limited to English-language use according to the store listing; Feature set is narrower than full-featured AI research companions that include PDF export or knowledge bases

## 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
