Adding an account: Go to Settings → Integrations and click Add integration. Select the platform and follow the sign-in flow.
Multiple accounts: You can connect multiple accounts from the same platform (e.g., two ChatGPT accounts).
Removing an account: In Settings → Integrations, click the remove button next to the account you want to disconnect. This removes the sync connection but does not delete previously synced conversations.
Sync status: Each account shows its last sync time. Sync happens automatically every 15 minutes. You can also trigger a manual sync from the sync banner.
