Chromex

A Codex-powered browser assistant for page context, tabs, voice, and image editing.

Chromex brings a Codex-powered assistant into Chrome’s side panel so you can work with the page, media, and files you already have open. Use Chromex to summarize webpages, ask questions about selected text, compare tabs, draft replies, turn YouTube videos into timestamped notes, generate or edit images, dictate prompts, and use realtime translation or live conference-style transcription when configured. Key features: • Page-aware chat Ask questions about the current page, selected tabs, highlighted text, uploaded files, screenshots, and images without leaving Chrome. • Context-aware page understanding Chromex can use page text, selected DOM content, visible-screen context, screenshots, or supported site adapters depending on the task and the page’s access rules. • YouTube workflows Summarize videos, explain the current moment, extract timestamped notes, and jump to supported timestamps from generated answers. • Selection and right-click workflows Highlight text on a page and ask Chromex about that exact context. Use quick actions such as fact-checking, summarization, or follow-up questions. • Image workflows Attach page images, upload reference images, generate new visuals, create infographics, and open generated assets from the local output folder. • Voice, dictation, and live modes Dictate into the chat box, use live voice features when supported by your local Codex runtime, or use API-based realtime translation for live interpretation and conference-style transcript workflows. • Profiles, skills, and site suggestions Choose reusable instruction profiles for research, marketing, product work, support, fact-checking, planning, writing, and more. Save site-specific prompt shortcuts for pages you use often. • Local bridge architecture Chromex uses a local native bridge for Codex app-server communication, authentication flow, generated files, diagnostics, and temporary runtime data. Sensitive runtime logic is handled locally instead of being stored directly in Chrome extension storage. Privacy and control: Chromex is designed for user-controlled workflows. Browser history, microphone access, desktop capture, host permissions, tab context, screenshots, and page actions are requested only when needed for the feature you choose to use. Chromex does not sell user data, does not run ad tracking, and does not store raw OpenAI API keys in Chrome extension storage. Requirements: • Chrome 116 or later. • Chromex local native bridge installed on the same computer. • A supported Codex/OpenAI account for Codex-powered chat workflows. • An OpenAI API key is optional and only required for API-only features such as realtime translation. Getting started: After installing the extension, follow the setup guide to install the local bridge and connect your Codex/OpenAI account: https://genexis-ai.github.io/chromex/install/ Privacy policy: https://genexis-ai.github.io/chromex/privacy/ Install Chromex if you want a practical browser assistant that understands the page in front of you, helps with real web workflows, and keeps sensitive runtime operations behind a local bridge.
