What sets it apart is the sheer breadth of bundled capability: rather than a single chat box, the listing describes more than 17 built-in plugins covering reading assistance, data extraction, prompt engineering, speech-to-text and image generation, all reachable from one floating blue dot on any web page. The extension is developed by iambuffett.net and has accumulated around 1,000 users with a 4.3-star average across 15 ratings, with version 4.8.3 published in July 2024. It is positioned as a free productivity add-on rather than a paid subscription product. Note that ChatWork™ Copilot is an independent third-party browser extension and is unrelated to Chatwork, the Japanese business chat and groupware service. It also has no official relationship with OpenAI; it uses OpenAI and other model APIs as underlying engines. **Pricing & Plans:** Free. The Chrome Web Store listing presents the extension at no cost with a large bundled plugin set; costs associated with the underlying model APIs are typically handled by the user's own API credentials. - **Web page Q&A:** Ask questions about the page in front of you — articles, docs, dashboards — and get GPT-4 answers grounded in its content. - **Table scraping:** Pull tabular content from a page into a clean, structured dataset suitable for spreadsheets or further analysis. - **Prompt optimization:** Run drafts through prompt-optimization models (BART-large-CNN summarization, prompt generator, prompt extend) to get sharper results. - **Speech-to-text and image generation:** Convert spoken input to text with OpenAI Whisper Large V2, and turn written prompts into images with DALL·E 2 or Stable Diffusion 2.1. - **One-click sidebar anywhere:** A small floating blue dot stays available on every site, opening a sidebar with more than a dozen built-in AI plugins at any time. **Strengths:** Free to install with no subscription for the extension itself; Very broad feature set: Q&A, scraping, prompt tuning, dictation and image generation in one place; Accessible on any site from a single floating icon; Supports several model families, including GPT-4 Vision and Whisper **Limitations:** Chrome-only: no Firefox or Safari build; Some companion web endpoints referenced in the listing are unreliable; Bundles many model providers, so output quality varies by task; Interface packs dozens of plugins, which can feel cluttered for new users [Profile (Markdown)](https://openaitools.app/tool/chatwork-copilot.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 ChatWork™ Copilot and Sider compare in monthly traffic?
