I've been looking at both Scrivener and Ulysses as tools to use in writing a book. It would be a bonus if I also found either one or the other to be useful for shorter writings as well from notes to essays to whatever. It seems both of these apps have their fans including best selling authors on both sides of the fence. Worthy of note, learning and using markdown would be a new thing for me. I'm not particularly thrilled about doing that versus just using a WYSIWYG editor instead. I think either of them allow you to write in an uncluttered view that hides the UI when you want to focus on the writing. I got the impression that one of Scrivener's strengths is support for researching information one might require. I will be doing some research simply to present certain information of interest and provide the reader with credible sources where it from. So that would be helpful not only for this project but I could see it being useful in the future for other writing as well. Something Ulysses seems to emphasize is keeping all of your writings in one place with global search across them all supported. I don't know if Scrivener works similarly or not. Just taking a superficial glance so far I got the impression from screen shots of the UI for each of them that Scrivener seems to incorporate more in the way of organizational tools for a given project but I may be completely off there with the limited investigation I've done so far. I think both apps offer free trial versions on their web sites that I just glanced at briefly this morning in which case I will give them both a spin to see them firsthand. Are there any writers here using one or the other or having had experience with both who could share some insight about the relative strengths and weaknesses of each product? I should also mention that this is my first foray into book writing. There is a topic I have wanted to write about in detail for over five years now and I think I'd like to move beyond daydreaming about it and actually do it. I've looked into these apps more than anything else hoping to find a good means to organize my ideas and structure them overall in a planning phase that would precede writing anything. I want a clearly defined roadmap that ensures I cover what I want to in a well thought out way. Naturally, being able to easily modify this and move topics around, etc. would be very helpful. Any advice for this novice would be greatly appreciated. If I am not thinking of important information needed to guide me here, please let me know and I'll be glad to try to be more specific.
