People who say they use ai for their oc's because they can't draw are silly, there's alot more you can use to make characters in that is better and easier then ai. Here's a post to help you choose something else other than ai that doesn't include drawing
THERES LITERALYYYY Anime bases (I make Anime bases myself and the thing I make bases on I haven't seen have other bases made of so if you want to draw your milgram oc but can't draw you can use my milgram bases (by the way if other people make milgram bases i'm not gonna start spreading rumours about them and call them copiers XD )
OR if you have a disibility which makes it so you can't draw with your hand or just don't want to draw at all theres dress up sites too like:
Neka: 捏咔-捏人创作分享平台 (NO intrusive ads, the neka are all beautifully drawn and from the ones ive used theres more skintone options than others, just not much poc hair options though or vitiligo etc)
Picrew: Picrew | The Character Maker & Creator (Has annoying 20 second long ads that you NEED to watch to use the picrews, but has some good quality picrews for all sorts of fandoms including murder drones, and just normal picrews not associated to fandoms, some picrews lack some skintones)
Meiker io: Free Game Creation Tool | meiker.io (Not my most favorite since it's mostly focused on dressing up random peoples oc's, but theres the odd few meiker's where you can make your own oc!)
CHARAT: Avatar Maker CHARAT (I don't see this one used as much but it's pretty fun, not many makers in it and finding how to start using them was confusing but I just need more experience, though I didn't find any poc hairs, though the skintone options is the most diverse you can get you can get pink skin to red skin etc)
Doll Divine: Newest Dress Up Games [Full List] (I'm pretty sure this is one of the oldest sites I use for dress up
Various other dress up games you can even download from the shope for apps on mobile devices (and some also on pc) for example theres, Gacha Club by Lunime and Gacha life 2 by Lunime (and other games by him). both are EXTREMELY creative apps for creating (AND POSING) your original characters! (Though theres some bugs/glitches in the game)
Apps by SeyeonSoft (I love their games)
Lovely cat world app, Aha World app (and others similar) where you can make your oc and actually walk around and interact with the world!
Apps by Inline planning Co., Ltd.
Neku (But it's not very "diverse" as it's mostly just curvey women with big lips and no other body types and ive seen a few STOLEN picrews on this one)
CUSTOM CAST App (VERY good 3D oc maker in an anime style!!!! WITH HAIR PHYSICS)
Vroid Studio VRoid Studio A FREE (YES FREE) 3D ANIME OC MAKER WHERE YOU CAN EASILY MAKE YOUR OWN HAIRS ETC, No blender needed! Ive been using this since I was TINYYY, you gotta keep using it to get better and find your style but it's very good and if you don't want to make your own asset's they have pre-made ones that you can even edit :D AND theres ALOT of good free to use assets on vroidに関する人気の同人グッズ51532点を通販できる! - BOOTH though check if the maker wants credits or not when posting publically!
(Honorable mentions where you need an account to use them: Avvy (A custom Vtuber app where you can make your very own FREE vtuber with their built in character maker WITH RIGGING) REALITY (The same as Avvy :D). Gogh (A study helper but ive made an oc in it, sadly you can only make ONE please correct me if im wrong though). ZEPETO (Not a big fan of this app but it has good customisation, you just gotta get past the forced in app notifications and it's hard to get Zems (if you wanna look cool you need zems) if you don't want ot download sketchy apps as "tasks" though if you take a few days to grind ads on the Benefits tabs which are scratch cards, or grind the Candy Slime in it!. GPark (A bit like roblox but if it was an anime style social media!) Animal Jam and Animal Jam Classic (Available on both mobile AND pc, it's great if you want to make animal oc's and run around the world with them! though theres an optional membership for cooler items!)
ALL of these sites CAN be used WITHOUT making an account and are ALL completely free! So If you can't or don't want to draw and or can't commission someone DEFINATLEY try these out instead of using ai generation
(Also not ALL ai is bad, for example the ai that's been used in games for YEARS before ai generation is very clever)
This post can even be for you guys who don't even use ai but can't or wont draw yet still want to make oc's <3
Tell me if there's any other oc makers I can add here <3 I love discovering more oc makers
