| Description | 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. | SignalZen is an AI-powered customer support and live chat platform for small and medium businesses. Its AI answers from your website, files and help center and hands conversations to human agents. The platform includes a customisable chat widget, an AI copilot that drafts replies for agents, a public knowledge base, two-way translation and conversation summaries. Agents can reply from Slack, Microsoft Teams or Google Chat. Plans are monthly: Starter is $29 (up to 2 operators), Basic $49 (up to 5), Pro $99 and Business $199 (both unlimited operators), with a 30-day free trial and no permanent free plan. |
