Fill in a plain PDF waiver with AI

For waiver forms with no fillable blanks.

Many GCs send waivers as plain PDFs with no fillable blanks. In the pay app's Lien waiver panel:

  1. Click Map with AI. AI finds each blank and what belongs there: project, amount, period, your company, signer.
  2. Review the values and click Use these values.
  3. Click Open waiver on screen to check placement. Values are set on the printed lines; fix or add anything there.

Mapping is saved with the pay app. Use Map again with AI if the form changes. It counts toward your monthly AI allowance.
