Chat SDK now supports cross-platform conversation history through the new transcripts and identity options. User transcripts persist across every platform adapter, allowing the same user to keep their message history wherever they message your bot.

import { Chat } from "chat";
const bot = new Chat({
  userName: "mybot",
  identity: ({ author }) => author.email ?? null,
  transcripts: {
    retention: "30d",
    maxPerUser: 200,
  },
  // ...
});

bot.transcripts exposes four methods, backed by one of the official state adapters:

• append: persist an inbound message or a bot reply

• list: return entries chronologically with filters

• count: total entries stored for a user

• delete: wipe every entry for a user
