| 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. | Keepi is a personal knowledge AI that runs inside WhatsApp. You forward it texts, links, images and voice messages, and it organizes them and answers questions based on what you saved. It transcribes voice notes, reads articles and extracts key information, and indexes saved content automatically. Keepi is operated by Dancing Apps Limited in London. No pricing is published on its website. |
