| Description | HuggingChat is Hugging Face's free, browser-based chat app powered entirely by open-source AI models, positioned as an open alternative to ChatGPT. Its Omni feature automatically routes each request to the best-suited open model, or users can manually pick a specific model to chat with. It's aimed at developers, researchers, and everyday users who want to experiment with cutting-edge open models for tasks like drafting emails and writing code without paying for a proprietary service. | Sider is a browser-extension AI assistant that overlays a sidebar on any website—Gmail, Google Docs, YouTube, PDFs, news, and social sites—so you can chat, summarize, translate, write, and research without switching tabs. It aggregates 20+ models (OpenAI GPT, Anthropic Claude, Google Gemini, DeepSeek, and xAI Grok) behind one subscription, aimed at students, freelancers, marketers, and knowledge workers who juggle reading, writing, and translation across the web. Its main differentiator is being an always-available in-page sidebar bundling many premium models plus a citing Deep Research agent, rather than a single-model standalone chatbot. |
