What's a Pantser or Plotter

Plotters
They already wrote an outline and know exactly what's going to happen in their story.

Pros for Plotters
There is a smaller chance for them to get writer's block, and they usually stick to a story longer than pantsers. Also, they happen to finish stories quicker, or at least more smoothly.

Cons for Plotters
They are confined to their outline, and if they have to change something, it changes the entire outline, which can be very daunting. Also, sometimes stories can seem too planned out and not natural.

Pantsers
They go with the flow, fly by the seat of their pants, and only have a general idea of their story,

Pros for Pantsers
It's less work upfront and stories can be more natural. They're not stuck to anything and if they don't like it, they can change it in one second.

Cons for Pantsers
It can be harder with no plan and it's easy to get writer's block. Also it's easier to drop a book.

Plantsers
They're a little bit of both, but usually, they lead heavily to one side.
