The everyday screen - open a project, fill in its form, submit to generate a PDF. This is also where the app lands on launch, before any document is open.

No document open

Three ways in, all from the Main Menu: Open File (pick a .yatate/.ypf from disk), My Projects (your own curated list, desktop/iOS only), or Online Library (browse ready-made templates, see Print the Sample Club Card).

The form

Fields render top to bottom in the order they're defined:

Field type What you see
Text A text box, with length/pattern validation if defined
Number Numeric-only entry, with min/max validation if defined
Currency A text box formatted as currency
Date A text box you can type into, plus a calendar-picker icon
Dropdown A picklist of the form's defined options
Checkbox A simple on/off switch
Image A photo picker
Signature A signature capture panel - Type (pick a script font) or Draw
Drawing A thumbnail of the reference image (if any) - tap to open a full-screen editor and mark it up
Repeating Group An "Add row" list of sub-fields, each with its own Remove
Label Static text - nothing to fill in, never in the generated data

Autocomplete suggests values as you type on some fields, drawn from autocomplete.json (see Autocomplete Editor) - never from anything previously typed.

Validation: field-level errors show inline; cross-field errors show as a banner after Submit. Nothing is generated until every check passes.

Presets, when a form has them enabled: Save current as new preset captures everything currently filled in; tap a saved preset to apply it; Clear blanks the form. A preset literally named "Default" auto-applies silently whenever the form opens fresh, if one exists. Presets are managed on their own screen - see Presets Editor.

Submit runs the full generation pipeline and lands on Output Preview on success. Nothing about the submission is saved anywhere except the generated PDF itself. Nothing is added to autocomplete.json either - that list only ever changes when the form's author edits it directly.

Reset clears everything back to blank.
