You can use a library to insert text in a PDF but you need to figure out at what coordinates to position the text and how you want the text styled. If you are constantly adding PDF templates, this is cumbersome work. If you don't have a tool for figuring out the coordinates (like the editor on pdfotter.com), your developers will have to do this. The last company I worked at faced this exact problem and it took us hours to add PDF templates to the system.

You do have a strong competitor in this space. Adobe. Which is admittedly costly for the the pro version, but can't be ignored. Why use PDF otter over them?

For filling in individual PDFs, yes, Adobe wins. However, I'm using the editor on my site to show off the PDF Otter API which helps you fill-in PDFs at scale. That's a tool that Adobe doesn't provide and how PDF Otter will earn money. I'm sorry that it's poorly advertised. I'm working on improving the homepage's copy and making it easier to transition from the demo to using the API.
