> Edit pdf like a word doc while preserving structure and format.
While I'm sure there are cases where this works pretty well and can be very useful, it may be worth noting that -- just like every other tool in this space -- there will be many PDFs where it simply can't work. It'll be hugely dependent on exactly how the PDF-generating application/tool went about things.
One simple example: suppose your PDF uses a specific font (not one of the standards like Times or Helvetica), so the PDF-generating tool embedded the font. (This is common.) Further, suppose the generating tool embedded a re-encoded subset of the font, including only the glyphs that were actually required. (This is also common.)
Now, suppose the edit you wish to make involves adding a character that was not present in the original document -- let's say you want to change the date from "May" to "June". But the original document contained no occurrences of capital J (in this particular font/style), and so the capital J glyph is not present in the embedded font. No "PDF text editor" can get around this; the best you can hope for is a "J" in some fallback (such as Times) that may look terrible alongside the intended custom font.
And as for edits that would require reflowing multiple lines of text, maybe inserting a new paragraph in the middle of a page, etc.... not much chance of this working out well.
Yes, a tool like this can (in many cases) make it possible to make minor changes (perhaps fixing a typo or updating a word here and there). To suggest that it can "edit pdf like a word doc" seems patently false to me.
