You can use all of Campfire Write's features without paying, but only to a point. You can only write 25,000 words in the manuscript writer on the free to use version, for example. Something to keep in mind!
Campfire Write is a program designed for people with big worlds and casts - so sci-fi authors, or historical - but it can be used by anyone!
When adding a character to your cast, you have a place to add their name, subtitle, image, description, attributes, image bank, physical traits, personality traits, and statistics. Attributes are preselected - you choose from a list, then fill those out. The rest you put down your own, then a description, and statistics gives you a place for a name, a number, and a unit of measurement. You can also make templates if you like how you've set up a character! There's also a place to add a backstory, or overall notes, and any other pages you want.
The tabs for Locations is the same as for characters.
There is a tab for maps - where you can save a zoomable image of your map.
The research tab is very customizable. You can add images, PDFs, text, videos, and urls. There's a separate notepad, and a separate place to add links to elements on Campfire.
The timeline tab lets you create as many plotlines as you need - so if you have romances, or subplots, etc - and you can draw connections between the various events. These events can have images (though they won't show in the overview), titles, a timestamp, and a description. Each event can also have attributes: including aliases, importance, whether it occurs on or offscreen, and have characters linked to them.
If you link a character to an event, you can track their arc! Using their arc, you can track how they change through the story.
Campfire allows you to make a Relationship web - you select what characters are shown, color code the lines, then draw lines between the characters!
You can make an encyclopedia! I love it! It's basically a wiki page. You have a basic image spot, a one-sentence summary, a space for short facts/summary, and then for anything you need to write! Tables, data, just a text dump! It's great!
Campfire is focused around sci-fi, and so there is a tab for magic. There you can write the source: emotions/objects, provide images, how it's channeled, what the cost of the magic is and what it can't do (cool!), and any exceptions, as well as the origins, rarity, and timeline!
There's also an area for species! It's very similar to the character tab, but with spaces for habitats, species' averages, and similar things!
Culture is very similar to characters, with some areas for 'attributes', and then a box for history, and items is close to characters. Systems is similar to both.
Language is brilliant! You can write or insert an image for a symbol, write out how it's pronounced, then any modifiers. Then you can make a dictionary, then have a free tab. There's also a religions and philosophy plotter.
The writer itself is pretty nice! Although it doesn't have Times new Roman as an option?? You can pull up any element at any time to view (character, location, item, etc) on the side bar, make comments and notes.
For what it is - a world maker, 10/10. But there's no plotter, and the writer itself is thoroughly eh. (Again, no Times New Roman?) So as a writing program, 4/10.
Out of all the 'plotters' I've found, Campfire Writer is the best... for everything except actual plotting. For characters, worldbuilding, etc, nothing beats it. So if you already have a plotter and writer, but need something for worldbuilding, then Campfire Writer is perfect. But if you're looking for a writer/plotter, then no. The app also works really well, though.
Campfire Writer lets you subscribe to each module individually. So if your story has a massive cast of characters, but you don't need the manuscript writer, religions, or anything else, then paying for the characters module and maybe relationships might be worth it. You can subscribe monthly, annually, or pay a one-time fee.
