About SideAI: AI Sidebar For ChatGPT - Free Access

SideAI brings ChatGPT into your browser sidebar so you can read, write, summarize, research, translate, and ask questions without constantly switching tabs. SideAI is the rebranded and upgraded version of Sidebar for ChatGPT. It keeps the familiar sidebar experience users already know and adds a cleaner interface, page tools, writing workflows, screenshot capture, Google Search insights, custom prompts, and more. The core sidebar is free and unlimited inside SideAI. You can open it whenever you need it and use your own ChatGPT account without adding an API key. Optional premium plans unlock advanced extension features, but the main sidebar access remains free. 🚀 Quick Overview SideAI helps you keep ChatGPT available beside any webpage. You can open the sidebar, select text for quick actions, improve writing inside fields, summarize pages, capture screenshots, and reuse saved prompts directly from your browsing workflow. Instead of copying content, opening a new tab, pasting, waiting for a response, and returning to the original page, SideAI keeps the assistant available where you are already working. Use SideAI for research, writing, studying, coding, shopping, email, documentation, forms, dashboards, product comparisons, support replies, and everyday browsing. ✨ Key Features ✅ ChatGPT Sidebar Open ChatGPT in a clean browser sidebar from any page.
