You can ask a question, get an explanation or hold a casual conversation while staying on the page you were reading, which keeps the flow of research and reading intact. The design goal is convenience rather than heavy tooling. There is no document indexing, no workspace or dataset management — just a chatbot that is there when you want it and out of the way when you don't. That makes it a low-friction option for people who want occasional AI help during everyday browsing rather than a full research platform. It is a free, lightweight extension published by the ChattyBuddy team, who also state that the extension handles personally identifiable information and personal communications, so it is worth reading the privacy policy before use. The listing carries a Featured badge and notes that it follows Chrome's recommended practices. One caveat: the extension was last updated in 2023, so the experience may lag newer AI chat extensions. **Pricing & Plans:** Free — the extension is distributed at no cost with no listed subscription. - **In-browser AI chat:** Chat with Buddy, an AI-powered chatbot, without leaving the page you are viewing. - **Broad topic coverage:** Hold conversations on a wide range of subjects as you browse. - **Lightweight footprint:** A small extension that adds a chat companion rather than a full workspace. - **Chrome-native integration:** Installs straight from the Chrome Web Store and lives in your browser toolbar. - **Featured listing:** Carries a Chrome Web Store Featured badge and follows recommended extension practices. **Strengths:** No need to switch tabs to a separate AI chat website; Free and very small footprint; Carries a Featured badge and follows Chrome recommended practices; Simple, focused scope that avoids configuration overhead **Limitations:** Last updated in 2023, so it may lag current AI chat extensions; No ratings yet on the listing; Declares handling of personally identifiable information and personal communications, so privacy policy review is advisable [Profile (Markdown)](https://openaitools.app/tool/chattybuddy.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 ChattyBuddy and Sider compare in monthly traffic?
