Free Websites / Tools that I use for Writing ! !

Organizational:

Notion : a personal favourite of mine. from what i've seen, unlimited projects with a variety of cards to use. it also has an mobile app with it. highly recommend.
Milanote : has some limitations on how many cards you can have but has different templates you can tinker around with. is more of a whiteboard type of site.
Hiveword : i haven't used it but it provides a novel-building template for plot, scenes, characters, etc.
Lucidchart : another i don't use but from what I've seen, it's similar to Milanote with their whiteboard style. also has a variety of templates of charts, diagrams, and more!

OneLook Thesaurus : my go-to website for finding synonyms. also provides definitions!
Language Tool : a chrome extension similar to Grammarly that acts as a grammar-aid tool.

Pinterest : a great source if you're searching for inspiration. you can also find tips and prompts on the site too!
Reedsy Character Name Generator : a name generator that include forename and surnames. has nationality specific names and a few mythic / fantasy name generators.
Fantasy Name Generator : this name generator has much more variety with character names and fictional location titles.
Inkarnate : a fantasy world-building site that I used in the past. fun fact: i made a little (it wasn't little) dragon shaped island for one story that never made it on paper.
