Questions & Answers

As answered by people managing Portkey and DocSpring.

Why should a person choose your product over its competitors?

DocSpring's answer:

One API covers PDF forms, Word documents, page designs and HTML templates, with the same JSON and the same e-signatures, so you don't need a second tool when a customer sends you a Word contract. Templates have typed fields and validation that catch bad data before a document is made. Test PDFs are free and unlimited, and the free plan has no time limit.

How would you describe the primary audience of your product?

DocSpring's answer:

Developers and product teams who build documents into their software: loan, insurance and rental applications, patient intake and consent forms, tax and government forms, contracts, invoices and certificates. That includes SaaS companies whose own customers set up templates in DocSpring's embedded editor.

What's the story behind your product?

DocSpring's answer:

I used to work at a payroll company (Gusto). We had built a similar in-house tool for filling out tax forms. I then built the first version of DocSpring (formerly named FormAPI) while I was living in Thailand. I built it to automate the filling out of visa application and visa extension forms, but realized that it could also be used for tax forms, real estate contracts, and any other kind of fillable PDF form.

Who are some of the biggest customers of your product?

DocSpring's answer:

  • SaaS services serving customers in the real estate, insurance, finance, and legal industries, among many others.

Which are the primary technologies used for building your product?

DocSpring's answer:

Ruby on Rails, React, Rust, Go, AWS

What makes your product unique?

DocSpring's answer:

DocSpring fills every kind of document from one API: PDF forms, Word documents, page designs and HTML templates. AI sets up the fields on any PDF, fillable or flat. The same template gives you a web form and e-signatures, and your customers can set up their own templates in our editor, embedded in your app. Your AI assistant can do all of this too, through our MCP server. DocSpring is SOC 2 Type II audited and HIPAA compliant, with US or EU hosting.
