Instead of copying text into a separate chat window, you open the side panel and work in place: highlight a passage to translate or summarize, ask a question about the page, or start drafting from a prompt. It is designed for people who live in the browser and want AI help without breaking focus. The feature set centers on everyday knowledge work. Writing tools help you draft, rewrite, and refine text; translation and summarization handle long content quickly; a prompt generator helps you get better results from other AI tools; and code analysis offers a hand when you are reading technical material. Because it runs as a browser extension, setup is a single install rather than a new application. Access model is freemium: there is a free tier with limited usage, and paid plans add more capacity and advanced features. As with any AI assistant, treat the output as a strong first draft — particularly for code and anything you plan to publish — and verify important details yourself. **Pricing & Plans:** Freemium. A free tier provides limited usage, and paid plans unlock more queries and advanced features. Check the provider's site for current quotas and prices. - **AI Writing Help:** Draft, rewrite, and polish text with an AI assistant that sits beside any page you are working on. - **Translation and Summarizing:** Translate content between languages and summarize long pages or documents in a few clicks. - **Sidebar Q&A:** Ask questions about the page you are reading and get contextual answers without leaving it. - **Prompt Generator:** Generate effective prompts and use them across other AI tools and workflows. - **Code Analysis:** Get help understanding and analyzing code snippets while you browse documentation or repositories. **Strengths:** Works as a sidebar on any web page in Chrome and Edge; Covers writing, translation, summarizing, Q&A, prompts, and code; No tab-switching distraction while you work; Free tier available to try before paying **Limitations:** Requires installing a browser extension; Free quota is limited, with heavier use behind a paid plan; Answers depend on the underlying GPT models and can need review; Tied to browser usage rather than a standalone app [Profile (Markdown)](https://openaitools.app/tool/gptplus.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/sider.md) ## Frequently Asked Questions ### How do GPTPLUS and Sider compare in monthly traffic?
