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 [Profile (Markdown)](https://openaitools.app/tool/sider.md) ## SummarizeIt SummarizeIt is a lightweight Chrome extension for people who want the gist of a page without reading all of it. Published by the developer archlab, it works on the page open in your browser tab and uses OpenAI's GPT-3 API to generate a condensed version of the main text. The pitch is straightforward: instead of skimming paragraph after paragraph for the important sentence, you trigger the extension and read a short summary instead. The extension is deliberately simple. There is no elaborate dashboard, no team workspace and no workflow builder — just a summarization action delivered inside the browser where you are already reading. Because it operates on the active page, it fits naturally into research, study and news-reading habits where you jump between many sources in a single session and need to decide quickly which ones deserve a full read. SummarizeIt is listed in the Chrome Web Store with a small user base of around two hundred installs and version 2.0 as its most recent release. It is offered free of charge. Note that the extension dates from 2023 and is built on GPT-3, so newer summarizing tools based on GPT-4-class models may produce tighter output; SummarizeIt remains a simple, no-cost option for a quick page digest provided the developer's API integration keeps functioning. **Pricing & Plans:** Free. The extension is distributed at no cost through the Chrome Web Store and advertises no subscription or paid tier. - **One-click webpage summary:** Summarize the page in your active Chrome tab without copying or pasting any text. - **GPT-3 powered output:** The extension uses OpenAI's GPT-3 API to generate condensed, readable versions of long text. - **Lightweight extension workflow:** Install from the Chrome Web Store and use it while browsing; no configuration screens or account setup are described. - **Reading-time saver:** Built for getting the gist of long articles, posts and pages without reading every paragraph. **Strengths:** Free to install and use, with no subscription tier advertised; Runs inside Chrome on the page you are already reading, so there is no context switching; Cuts long articles down to a short digest so you can decide what deserves a full read; Minimal interface keeps the focus on the summary itself [Profile (Markdown)](https://openaitools.app/tool/summarizeit.md) ## Frequently Asked Questions ### How do Sider and SummarizeIt compare in monthly traffic?
