Prompt Viewer is a powerful Chrome extension to quickly and easily inspect the metadata embedded in AI-generated images.
Key Features & Benefits
○ Instant Metadata Access: Simply right-click on an AI-generated image on any webpage and select "View Prompt Info" from the context menu. No need to download images or use external tools.
○ Comprehensive Support: Clearly unpacks and displays essential metadata (prompts, settings, parameters) from images generated by Stable Diffusion WebUI, NovelAI, and ComfyUI.
○ Multi-Format Data Extraction: Retrieves information from various PNG text chunks (tEXt, iTXt, zTXt) and relevant EXIF data.
○ User-Friendly Interface: Presents extracted information in a clean, organized modal window, separating prompts, settings, and raw data for easy reading and copying.
○ Copy Key Information: Quickly copy prompts, negative prompts, or raw parameter strings to your clipboard with a single click.
○ Learn & Replicate: Understanding the generation parameters helps you learn new prompting techniques and replicate or adapt image styles.
○ Bilingual Support: Interface available in English and Korean, with automatic language detection based on your browser settings.
※ Note for ComfyUI Users
ComfyUI workflows are highly flexible and can involve numerous custom nodes. While Prompt Viewer strives to parse and display the most common and significant parameters (like models, LoRAs, prompts, and core sampler settings), the sheer diversity of custom setups means that metadata extraction for ComfyUI might be incomplete. However, the extension always provides access to the complete raw workflow JSON data, allowing you to manually inspect all details if needed.
