What is this

charshare lets you create, publish, and chat with AI characters — without signing up, a server, or anyone standing between you and the network.

• Local-first. Everything you do — characters, chats, personas, preferences — lives on your device first. Publishing to the network is a choice, not a requirement.
• No backend. charshare ships as a static site (deployable from any CDN) or a desktop binary. There is no server of ours in the loop.
• Peer-to-peer. Anything you publish travels over Nostr, an open relay-based protocol, through relays anyone can run — including you.
• You own your identity. Users and characters are identified by a public key, not a username/password pair. Every event is signed client-side per the Nostr protocol (secp256k1); nothing you publish can be forged or reassigned by anyone else, including a relay operator.
• Bring your own AI. Configure OpenRouter, Hugging Face, or a self-hosted Ollama instance. Your key, your requests, straight from your device to the provider you chose.
• Free as in freedom. AGPLv3. Run it, read it, modify it, fork it, self-host a relay.

Features

Browse	Search by name, tag, or @username/@pubkey; block tags/authors locally
Characters	Create, edit, fork, delete; signed version history; local-only or published; comments
Chats	Local-only, branching message tree (on edit/regenerate), personas, backgrounds, import/export as JSON
Profiles	Signed profile documents, @username claims, searchable name index

Try it

• In the browser, no install: jim-ww.github.io/charshare

• As a desktop app, download a binary from Releases (Linux, Windows, macOS)

• Via Nix, try it or add it to your flake:

  nix run github:jim-ww/charshare

Building from source

The frontend (SvelteKit + Tailwind/DaisyUI) is wrapped in a Wails desktop shell, but also builds standalone as a static site — same code, either target.

With Nix (recommended)

nix build           # produces the desktop binary at ./result/bin/charshare

Without Nix

Requires Go 1.23+, Wails CLI, Node.js, and pnpm. On Linux you'll also need webkit2gtk (4.1) and gtk3 dev packages.

cd frontend && pnpm install && cd ..
wails build         # desktop binary in ./build/bin

To build the frontend alone as a static site (no Wails/Go needed):

cd frontend
pnpm install
pnpm run build      # outputs to frontend/dist

Legal

Users are solely responsible for content they publish, under the laws of their own jurisdiction — charshare is software, not a service, and takes no responsibility for what anyone does with it. There is no server, no signup, and no one positioned to moderate or remove anything on our end. See /legal for the full statement.

charshare has no subscription and no ads, and never will. If you'd like to support it anyway, donations are welcome.
