Syncia
Syncia: ChatGPT Sidebar Extension for Any Website
Syncia is a free, open-source Chrome extension that brings ChatGPT to any website, letting you chat, summarize, and edit text without leaving your current page.
Overview
Syncia transforms your browser into a smart, AI-powered workspace by embedding ChatGPT directly into every webpage you visit. Instead of switching tabs to access an AI assistant, you can simply press a shortcut to reveal a sidebar and start chatting with GPT while browsing, reading, or researching. This seamless integration makes it easy to get instant answers, explanations, or ideas without breaking your workflow.
Beyond the sidebar chat, Syncia shines with its quick menu feature: highlight any text on a page and a floating menu appears, offering instant summarization, grammar checks, translation, and text-length adjustments. Whether you're skimming a long article, refining an email, or studying complex material, Syncia's contextual tools let you manipulate text right where it lives. Customizable settings and prompts, plus support for your own OpenAI API key, give power users full control over how the extension behaves.
Built as a free and open-source tool, Syncia appeals to students, writers, researchers, editors, and content creators who spend significant time reading and writing online. It removes the friction of copy-pasting content into a separate AI chat window, making AI assistance feel like a native part of the web itself.
