Keep it
Nothing PDF Annotator does is plain enough to make in a weekend. The 3 things listed below take a company.
That makes this kind of software worth paying for, not this one in particular: 26 of the 45 other PDF editors grade higher. It costs $79.95, paid once.
What you could not
- Editing the text inside a PDF without breaking its layout.
- A real app for Windows. Something home-made would be a web page.
- It is priced for each person, which means accounts and billing for a team.
What this rests on. PDF Annotator’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
