ContextAI Translate

Select text, right-click → translate with ContextAI. First-time: copy user id from webapp into extension.

ContextAI Translate brings fast, private, and professional translation and summarization to your browser — right where you need it. With ContextAI Translate you can: Translate selected text from any web page via the right-click menu. Open a compact side panel (or popup) to view translations, request summaries, and manage translation history. Choose and save your preferred target language so translations use your preferred wording automatically. See a shortened user ID in the panel and copy the full anonymous ID when needed. Buy tokens on our website to continue using the translation service (link in the panel). How it works (simple, privacy-conscious flow): Open the ContextAI web app (https://contextai.necta.us ) and copy your anonymous user ID shown there. Paste the ID into the extension side panel and click Save — the extension will store it locally. Select text on any page, right-click → Translate with ContextAI. The side panel will open (or the popup will), automatically show the selected text and translate it (if an ID has been saved). Key features Right-click translation: Translate any selected text without leaving the page. Side-by-side UI: View source and translation, plus an optional summary area. Auto-translate on selection: If the extension already has your ID, a selection triggers an automatic translation. Persistent target language: Choose and save a target language; translations will use the saved setting. Token & balance display: See remaining tokens and navigate to our buy page to top up. Manual ID flow for privacy: The extension never auto-creates or requests your user ID; you paste the ID from the web app to link your account — this gives you control over when the extension communicates with the backend. Robust behavior: Works with Chrome side panel when available; otherwise opens a compact popup to keep the experience seamless. Who this is for Translators, researchers, and knowledge workers who need quick, contextual translations while browsing. Teams who want a lightweight, private way to translate selections without copying/pasting between apps. People who prefer a manual, auditable connection between browser extension and backend (you control the anonymous ID).
