What differs for built-in forms

For letters delivered as DOCX, templates are built in Word (12), a fillable PDF form (3) and a visual builder (1). Among them, 3 need Zapier, Make or n8n to read answers to their own forms, so they sit after the tools with a direct connection. Of these, 4 have a free tier.

Besides DOCX, these tools for letters also write PDF (11), e-sign documents (4) and XLSX (1). A submission to the tool's own form builds the document from the answers. Published starting prices run from $19.50 to $209 a month, the top end from Knackly. Prices were checked on 20 Oct 2026.
