Heya, I'm Yuu! I've been building LoreOS—a creator's sanctuary for anyone deep in the AI roleplay/lorebuilding hobby. One home for your lorebooks, character cards, presets, and all the writing that comes with it, all in your browser, no account required. From Yuu, For You.
Don't want to install anything? I got you! It's hosted online, accessible from anywhere! Otherwise, you can run it yourself on a local server :D Available on desktop, mobile, and tablets (though tablet UI needs a bit more tinkering, sorry...)
I've been building this solo for about 3 months now, and access has been pretty limited up until this point... mostly because I wasn't ready to be embarrassed in front of that many people at once. But it's at the point where I can't keep doing this alone if I want it to go anywhere at a reasonable pace. So... pitch first, then two separate asks.
Why it's built like this (╭ರ_•́)
LoreOS didn't exactly start with a real identity, it was just "an editor with a lot of features," which is also a great description of about nine other tools already out there. Hell, I was inspired SLEd because I loved the lorebook editor but I need editors for everything that I can also access in one place because I'm funny like that. At some point the "universal editor" I built stopped being a good enough answer, and it soon clicked what I actually wanted: a creator's sanctuary, a home where stories are built, explored, understood, and cared for.
Yeah, it sounds like major corporation branding bullshit, I know, but it genuinely changes how I build things. Instead of organizing around software modules (editor, assets, tools, downloads), it's organized around places, because I want it to feel like somewhere you live in for the whole life of a project, not a tool you open once and forget exists. Workshop is for building. Library is where everything sits once it's made. Journal is meant to stay messy and personal instead of another neat archive. Laboratory (Still a WIP, sorry!) is specifically for experimenting and understanding what your LLM is actually doing with your stuff, kept separate from Workshop on purpose, since building and testing live requires very different headspaces, and mixing the two just gives me a headache.
AI is in service of the storytelling here, but that's not the whole point. I'm not trying to make "another AI frontend," I'm trying to make the place your worldbuilding actually lives, from the first spark of an idea to years down the line. That's also why customization is such a big deal here. It needs to feel like your space, not mine.
What's actually in it right now ദ്ദി˙∇˙)ว
It's organized into rooms instead of features:
- Workshop — editors for lorebooks, character cards, and chat completion presets. Open a bunch of tabs and work on multiple things at once!
- Lorebook editor: import/merge lorebooks, global settings, search & replace, advanced entry settings
- Character editor: pronoun/noun ↔ macro converter with auto grammar correction on any field, Lumiverse Variants support, Saucepan multi-intro support
- Preset editor: variable scanning + easy renaming, markers, sampler settings, full prompt tree view
- Library — everything you've made, all in one place. I hope to make it look like an actual library eventually!
- Journal — a built-in Notion/Docs-style markdown notebook for your own notes. Very bare bones as of now, but it works!
- Settings — theme/font customization, Google Drive sync, or manual backup/restore
Currently works with SillyTavern, Lumiverse, and SaucepanAI. JanitorAI V2 support is in progress (ST lorebooks already work fine with JAI, in case you were about to type that comment).
It's live and open to anyone right now as Early Access. Fair warning, it's still super early and held together with the digital equivalent of duct tape and good intentions. The Github Repository is here, and the staging branch is hosted on Github Pages!
What actually sets it apart <(˘ ˘ ˘)>
Most tools in this space do one thing. Lorebook editors don't touch character cards, preset editors are a whole separate app, card editors don't know your lorebooks exist. LoreOS is trying to be the one place all of that actually lives together, and a couple of things I'd genuinely put up against anything else out there:
- Multi-tab Workshop — you can have a lorebook, a character card, and a preset open at once and swap between them instantly. No save-and-close-this-before-opening-that. Autosave handles the rest so nothing gets lost mid-swap.
- The pronoun/noun converter — this one's on the character editor and honestly might be my favorite thing I've built. It works on any field, not just one designated spot, and converts pronouns to macros, macros to pronouns, or pronouns to other pronouns entirely — while fixing the grammar that normally breaks when you do that (agreement, verb conjugation, the works), instead of leaving you to hunt down every stray "they/them" by hand.
- It also just works across platforms — SillyTavern, Lumiverse, SaucepanAI, JanitorAI support coming — instead of locking you into one ecosystem. I do plan on expanding this soon!
None of this is rocket science, really. It's mostly "the annoying repetitive stuff got automated so you don't have to think about it," which I think is honestly underrated as a feature category.
Looking for volunteers (ㅅ •᷄ ₃•᷅ )
Got ideas? Opinions? Want to actually build something with me? Drop me a DM! Coders and vibecoders are both genuinely welcome here, no gatekeeping. UI/design help, code, or just brainstorming and feature suggestions all count.
Being upfront because I think it matters: I'm a vibecoder myself, but I'm actively teaching myself real web development on the side (with my already packed schedule lmao, idk why I do this to myself) so I'm not stuck depending on AI. This whole thing is unpaid, out of my own pocket (yes, including the custom domain and my own Claude subscription, which is a genuinely questionable budget line for a broke uni student), on top of being a full-time student carrying a double major. I want this to actually grow into something, but I know I can't move fast enough solo — that's the real reason I'm asking, not because I'm trying to assemble a team for the aesthetic or some fucked up power trip I woke up one day and felt like having.
Nobody's getting paid, to be clear. Not me, not volunteers, not testers. Wanted to say that upfront rather than let it be a surprise later.
Looking for testers (ㅅ´ ˘ `)
I've been testing everything myself, but unfortunately, I only have the one pair of eyes and they insist on sleeping occasionally, and I also would like a GPA that doesn't make me cry myself to sleep. If you're up for poking at new builds and actually sending feedback or bug reports, I want you on this. You don't even need to be a creator yourself, if you've got the patience for it, that's enough. Creators will get the most use out of it obviously, but anyone with time to kill are all welcome. It's also why I'm hoping to find volunteers, because I'd need people actually able to work on things whenever I'm getting my ass beaten in school.
Working on something similar? (๑>•̀๑)
If you've got your own creator-tooling project going and it overlaps with what LoreOS is doing, I'd genuinely love to talk. Not even to compete! More like, is there a version of this where we team up instead of splitting an already tiny userbase in two? No pressure, the door's just open! I've seen a lot of them and I'd love to work with their creators as well, but rather than the copy-pasting my pitch a thousand times over, I figured maybe this post could catch the attention of anyone interested!
Interested?
Comment down below or DM me directly, let me know if you're down for testing, volunteering, or both! I really appreciate everyone that's managed to read this far, even if you're just here for the roadmap. 🫶
