A method of determining placement of an input indicator on an electronic fillable form may include identifying, by an electronic device, a confidence map associated with an electronic fillable form. The confidence map may include, for one or more fillable fields of the electronic fillable form, a set of coordinates that define an area associated with each of one or more zones. The method may include receiving, by the electronic device, a selection of a portion of the electronic fillable form associated with one or more selection coordinates of the electronic fillable form, identifying a zone to which the selection coordinates correspond, and causing an input indicator to be displayed in a fill zone associated with the identified zone.
