Instead, the app sends one prompt to several models simultaneously, then lays their responses side by side so you can spot agreements, contradictions, and gaps at a glance. Supported models span the major commercial families plus open-weight options, and the same account gives access through a single subscription rather than a stack of separate AI plans. Beyond model comparison, ChatHub bundles practical assistant features: document and image upload for analysis, web search for real-time information, code snippets with syntax highlighting and live preview, an image generation workspace using popular diffusion and image models, a searchable prompt library, and built-in translation and web summarization tools. The interface is deliberately familiar, resembling a standard chat UI with a model picker, so the learning curve stays short. ChatHub is available as a web application, a Chrome browser extension, iOS and Android apps, and desktop clients for Windows and macOS, which makes it easy to move between devices or work alongside whatever page you are reading. A free tier covers basic use, while heavier usage and premium features require a paid plan; consult the pricing page for current limits. **Pricing & Plans:** Freemium. A free tier covers basic usage; premium plans unlock more usage and advanced features such as higher message limits and additional models. See the official pricing page for current tiers. - **Side-by-side multi-model chat:** Send one prompt to several leading chatbots at once and compare answers in parallel to spot hallucinations and disagreements. - **One subscription for many models:** Access the latest commercial models plus open-weight options through a single plan instead of juggling separate subscriptions. - **File upload and web search:** Attach PDFs, spreadsheets, and images for AI analysis, or pull in real-time information from the web when you need current facts. - **Image generation workspace:** Generate artwork, illustrations, and photos using popular image models without leaving the chat interface. - **Apps across every device:** Use the web app, Chrome extension, iOS and Android apps, or Windows and macOS clients, with a prompt library and code preview built in. **Strengths:** Genuinely useful parallel comparison that reduces reliance on a single model's output; One subscription and one interface for many different AI models; Available on web, browser extension, desktop, and mobile; Includes extra tools such as image generation, prompt library, translation, and web summarization **Limitations:** Requires internet access and depends on third-party model providers being available; Full model access and higher usage limits sit behind paid plans; Multi-model answers consume more tokens and quota than a single chat, so usage can add up [Profile (Markdown)](https://openaitools.app/tool/chathub.md) ## ChatWork™ Copilot ChatWork™ Copilot is a chrome extension in the busy category of 'AI sidebar' tools. 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) ## Frequently Asked Questions ### How do ChatHub and ChatWork™ Copilot compare in monthly traffic?
