What V1 means

Designed for the common signature job.

Draw or type

Create a visible signature with the mouse, touchpad, or a typed name in a handwriting style.

Place and resize

Put the signature where the document needs it and size it before saving.

Not cryptographic signing

V1 is for visible signatures. It does not include certificate-based digital signing or identity verification.

Signing should feel private.

Contracts, medical forms, tax forms, and client PDFs should not feel like upload-first workflows.

  • Everyday editing is designed for local Windows use.
  • Core tools do not require an account.
  • Future AI features will be optional upgrades.
