Chrome extension that streams brief and detailed explanations for any selected text using OpenAI-compatible chat completions. The entire codebase (including UI/UX) was authored by GPT-5.1-Codex-Max using a Volltin-provided prompt.
- Low-profile circular
?bubble appears on selection with a subtle charge ring; a quick hover (or click) opens the compact preview card for an ultra-brief explanation, and another click expands into full details and controls. - Streams short + long answers in parallel; shared request cache avoids duplicate calls for identical context.
- Context-aware: page title, URL, nearby text, and custom templates/prompts (system/short/long) are fully configurable, with adjustable prompt length cap.
- Modern glassmorphism UI with smooth enter/exit animations; options page for API key/base URL/model/prompts/templates.
- Open
chrome://extensions, enable Developer Mode, click “Load unpacked”, select this folder. - Open the extension popup or options page, set API key, base URL, model, prompts, and template.
- Select text on any page → hover or click the
?bubble to open the compact preview → click to expand for detailed view.
- Manifest V3, background service worker handles streaming and shared request hashing.
- Content script manages bubble + compact/expanded card, animated transitions.
- Options page persists settings in
chrome.storage.local.
- Built end-to-end by GPT-5.1-Codex-Max.
- Prompt and direction provided by Volltin (who did not write a single line of code).
