writing programs!!

hi :D

so basically I am here to ask everyone what writing software they use to write their own novels, fanfics, poetry, whatever! writing is writing

I'm curious to see if people use one single software for planning stuff out, if they use apps on their phones, heck planning through pen and paper is cool too, or if people use different apps for different aspects of writing (notion for chatacter planning, obsidian for plot planning, word/docs/wtv for... writing- I'm just pulling stuff out), I also wanna take inspiration to see what might work best for me and also hope other readers will do the same :DDD
