Our list of worldbuilding resources includes World Anvil, which sounds like it's what you're looking for.
Welcome, Worldbuilder! If you’re a writer or author, World Anvil is a game-changer in the best way possible! Our integrated worldbuilding system is the perfect World Bible for storing your setting information, images and research. Our mentions system makes it incredibly easy to navigate! You can map out and nest your plots, plan your character arcs, keep track of locations, side characters and languages, and add timelines to document the history behind your writing.
You can also publish your writing on World Anvil with the easy-read prose template, and give access to select groups - for example, your Beta Readers or your Patreon supporters. You can embed images and soundtracks into your work, and change the presentation of your world’s pages, for an even more immersive reading experience.
It's a free service if you put up with advertising, or you can pay to be ad-free.
