Resources
The first resource we've been using since 2011--the one that helped us realize we are plural. It's very good for introducing people to dissociative disorder related plurality as a concept, though it is very word-y and medical.
A bot for Discord that creates profiles for systems, alters, and more, lets you type as your respective selves, and even has front history/tracking functionality. Highly reccomended if your system is on Discord frequently.
PluralKit Dash - A web interface for the bot. Ours, for example.
Pluralkit.xyz - A way to display pluralkit member/system information. Ours, for example.
Iris' tools - Tools for PluralKit created by Iris, including PKFronters, PKSwitcher, and more.
Codes by PALS - Other code by the creator of pluralkit.xyz and the PluralKit Dash.
Petal's tools - Tools for Pluralkit by Petals, including Server Settings among others.
Front Calendar - A way to display your front history via your system token.
Avatar Savior - A tool for saving all of your avatars via export.json.
For Web - iOS - Android
A customizable application that can contain profiles for alters, organization via folders, has front history/tracking functionality, a chat for internal discussions, system reminders, the ability to friend other systems so you can see who's fronting on their end, and more. It has PluralKit profile syncing functionality.
Plurali.icu - A third party way to display Simply Plural information on the web.
A journaling website for systems. It also has ways to write system rules, a system wishlist, an internal forum for alters, ways to customize what words are used for your account (like changing the word for "system" for example), and more. It has PluralKit and Simply Plural importing functionality.
Not exclusive to systems, it is an alternative to pronouns.page that displays an account with multiple profiles, so you can show everyone's pronouns on their own profile. Ours, for example.
A wiki for all kinds of different plurality related terms.
The flag we created for systems that have dissociative disorders (such as DID, OSDD, UDD, and P-DID)! We will make an official website for it eventually.
