Chat on your Solid pod. One self-contained HTML file, no build, signs in with the universal xlogin pill.

yap is the chat suite for the solid-apps ecosystem, built in phases toward a Telegram-style messenger over pod and nostr.

A two-pane messenger for 1:1 encrypted direct messages:

• Roster (left): your conversations — contacts (kind:3 follows) plus anyone you've exchanged messages with — newest first, with avatar, last-message preview, timestamps, and unread badges (read state saved to your pod at /private/yap/read.jsonld).
• Thread (right): a live chat. Messages are NIP-04 encrypted (kind:4), signed with your WebID identity key (read from the shared keystore at /private/nostr/keys.jsonld — one key, every app), published to your relays, and delivered live over a standing subscription.
• LAN-only toggle (🌐 → 🔒): route a conversation over your pod's relay + the contact's relay only, so it never touches a public relay. (Plain ws:// LAN relays only work when yap is served over http, e.g. your local jspod.)
• + New: start a chat from an npub, hex pubkey, or a WebID / pod URL (resolves the key from their card's verificationMethod).

Identity, keys, follows, and relays are managed in the nostr app; yap reads the same keystore so it's the same you everywhere.

Pod rooms (Solid Chat meeting:LongChat JSON-LD) and live nostr group rooms (kind:42, per-device keys) shipped in the previous version. They're temporarily set aside while the DM shell lands, and fold back into the roster next.

• Group rooms (pod + nostr) back in the unified roster
• NIP-17 gift-wrapped DMs (hide the p-tag / metadata)
• Pod ↔ nostr mirroring (durable history + live delivery), reactions, media, markdown, Type Index chat discovery

Static — open index.html, or install via the store to /public/apps/yap/. Needs a Nostr identity (set one up in the nostr app) to send DMs.
