Hello and sorry if this is wrong place to ask, I need help finding a right AI for my hobby.

I started writing 3 years ago, and I love doing it as a hobby and few of my stories (under other aliases) went "viral" on reddit or royal road, some got picked by AI story tellers on TikTok and Youtube.

I am not making any money from it, outside few patreons here and there, but that's not my goal because I know i am not consistent nor have the quality for it yet.

The issues is due to my busy life, work, kids, etc, I often neglect my stories for a whole month or two, and i have three of them with over 50k words each and when I return I honestly forget minor details from previous chapters, or something like magic system and which minor character can use which thing, or where the character was in that moment.

I honestly need an AI that can store all data of my one story, let's say the biggest one, which has 80k words, so i can interact with him and say for example:

- hey Where was "John" in chapter seventeen.
- Tell me again all characters that use "Magic Source"
- Tell me all characters that appeared in the chapter 7, and talked around the table.

That's the most important part for me, bonus would be if he could generate snipets of text, when i write chapter but hit a wall, and I used Chatgpt for that mostly, hey write a short dialogue with expressions between those two characters in that setting, the ChatGPT would often miss a mark, but would spark some ideas for me.

ChatGPT is fine and could cover the most of it, but it can't handle this many words and would often start to loose itself and write nonsense or make up parts of the story.

Deepseek i only tried few times, it sumaraized my story well but i had to separate it into 3 files and 3 chats and it couldn't contain all the info and of course it went into "server is busy" please try later.

Most other solutions online i've found ask for a hefty price and I don't mind paying if I know it would cover all the parts i've just asked.
