| Description | WISHUPON is a universal shopping wishlist app and browser extension that lets shoppers save products from virtually any online store into one place. Users can organize items into collections, build gift registries, share lists with friends and family, and get notified when prices drop. It is available on iOS, Android, and as a Chrome browser extension. | 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. |
