Learn by checking a file

From a file to an answer.

Read the saved prompt, inspect a workflow or compare an export. Each worked guide includes the files and the result to look for.

How to check an AI image

Follow a complete review, from an original file to a useful record.

Build an API workflow

Run the Node.js examples and handle results without exposing private inputs.

Saved prompts, workflows and image records

Read AUTOMATIC1111 parameters from a PNG

Extract saved AUTOMATIC1111 prompts, negative prompts, seeds and settings. Try a downloadable PNG and compare the exact result.

Read InvokeAI metadata from an original PNG

Inspect a supported InvokeAI PNG record, including saved prompt, seed zero and CFG scale. Download a controlled file with expected output.

Read saved image seeds, steps and CFG settings

See which generation settings an image actually stores. Compare two permitted files with identical pixels but changed seed and step values.

Why an image returns no saved prompt

Compare a PNG with a known prompt, the same pixels without it and conflicting records. Understand what a missing result can and cannot mean.

Read PNG tEXt, zTXt and iTXt prompt records

Download three PNG encodings of one known prompt and compare their extracted values. Learn why readable text and verified authorship are different checks.

Extract a ComfyUI workflow from a PNG

Inspect two saved ComfyUI records, view their node types and download the original JSON. Try a PNG with an editable graph and API graph.

ComfyUI workflow JSON and API prompt JSON

Compare the editable workflow and API graph saved in one PNG. Download both controlled records and see why prompt JSON is not just prompt text.

Compare an image copy with a re-export

Measure file hashes, pixels and saved prompt records separately. Download a byte copy and a PNG re-export with reproducible observations.

Can identical images have different AI metadata?

Yes: compare controlled files with identical decoded pixels and different saved seeds, steps or prompts. Download the files and inspect the results.

Compare image creation records before and after an edit

Compare saved prompt, seed, steps, model and workflow fields across two files. Read changed, unreadable and unchanged states with a worked example.

Inspect the evidence

Check TIFF image metadata and AI signals: inspect a single-page scan or export, keep the original file and understand what its saved records establish.

Browse the Image Metadata Lab: seven controlled cases with downloadable PNGs, exact hashes, recorded outputs and reproduction code.

Build these checks into a workflow with the image metadata API guide and runnable CLI.
