Try it. Then check the evidence.

A real notice-to-sign workflow, powered by Claude Sonnet 5.5.

First launch can take about a minute.

This demo runs on Render Free. The server sleeps after 15 minutes without activity and needs time to restart. Keep the app tab open while it wakes. The landing page and saved PDF stay available separately.

Keep the exception.

One notice. Two entrances. Watch a real photo-to-PDF workflow, with English narration and captions.

The film loads only when you press Play (9.7 MB). English captions are already in the picture. The opening is a labelled AI illustration; the app footage shows real execution with shortened waiting. AI checks do not certify human readability.

What to try

  1. Use the sample notice.

    Start with the provided synthetic photo. Sample inputs go through the real pipeline.

  2. Find key details.

    Compare the actual extraction with the source. It must keep the audience, action, location and date/time.

  3. Confirm the pickup exception.

    Wheelchair-accessible pickup remains at the Main Entrance. Check both the condition and its linked instruction, then redesign.

  4. Open the five readings.

    Use Details or View checks and changes. These compare the sign’s AI readback with the facts you confirmed.

  5. Download an A3 PDF.

    Also try the editable SVG. The checked artwork is the artwork used for export.

Optional: in the checks, choose Try a memory check for a two-second recall exercise. Repeating it is practice, not a study of readability.

Where AI earns its place.

  1. PhotoReal uploaded input
  2. FactsAI reads and extracts

  4. Rendered signBounded layout, actual image
  5. Fresh AI readbackRead the finished image

Fresh readback receives the rendered image, not the source or expected answers. Its separate parsing request receives only that reading. A mismatch can trigger up to two layout repairs, followed by a new check. If it still fails, the workflow stops.

What works, and what the check can prove.

Evaluation limits

English, one main instruction, temporary jobs and two concurrent AI workflows. A busy response can require a retry.

AI checks concern content recovery and layout. They do not certify human readability, accessibility or a physical reading distance. No measured commercial ROI is claimed.
