A viewer that reads and displays the Stable Diffusion generation data embedded in an image. It pulls out the prompt, negative prompt, seed, sampler, steps, CFG scale, model name (hash), and any LoRAs used, and lets you copy each one with a click. It supports AUTOMATIC1111 (A1111) WebUI PNG info, ComfyUI embedded workflows, NovelAI metadata, and generation info stored in JPEG/WebP EXIF UserComment. It's handy when you want to recover the prompt from an image you generated earlier, inspect the settings behind an example you found on Civitai or X, or note a seed so you can reproduce the same composition. It's read-only, so it never alters your image, and you can expand the raw metadata to see exactly what's embedded. Because prompts are often as private as a recipe, this tool never uploads your image — all parsing happens locally in your browser.

How to use

  1. Drop an image in, click to choose a file, or paste an image (Ctrl/Cmd + V).
  2. The prompt, negative prompt, settings (seed / sampler / steps / CFG / model), and LoRAs appear automatically. Use the Copy button on each block to grab them.
  3. Open "Raw metadata" to inspect the exact embedded text when you want the full details.

FAQ

Are my images uploaded to a server?

No. All metadata parsing happens in your browser. Your image is never uploaded, stored, or sent anywhere — it is processed only on your device, so it's safe to use even when you don't want to expose your prompts.

Which generation tools does it support?

It reads AUTOMATIC1111 (A1111) WebUI PNG info, ComfyUI embedded workflows, and NovelAI metadata. It also reads generation info stored in JPEG / WebP EXIF UserComment.

Why is no prompt showing up?

The image probably has no generation info embedded. Metadata is commonly stripped by social media uploads, re-saving in an editor, screenshots, or compression/conversion — once removed, the prompt can't be recovered. Try the original output file.

Can I see the seed, sampler, and LoRAs too?

Yes. When present, it lists the seed, sampler, steps, CFG scale, model name (hash), and the LoRAs used. The settings block has a "Copy all" button to grab them together.

Does it modify or edit the image?

No. This is a read-only viewer; it never touches the pixels or the file. If instead you want to remove the generation info (prompt, etc.) from an image, use the Clean Metadata tool.

Does it work on phones?

Yes. It runs entirely in the browser, so you can load an image and inspect its generation info on a phone or tablet.
