Can PlugThis rebuild Grant Form Autofill?
“It is just a structured snippet library mapped to grant form fields.”
Grant Form Autofill stores reusable answers to common application questions and helps insert them into forms. You can easily build this using local Chrome storage or a Supabase backend to store categorised question-and-answer pairs, with a side panel or content script to inject them into any application page.
