I’m a dedicated ChatGPT user, and I’m extremely frustrated by the lack of cross-device chat syncing. It makes no sense that my memory syncs across devices, but my chat history does not. This creates confusion, inconsistency, and a poor user experience—especially when switching between my phone, tablet, and PC.
I’m requesting that you implement full chat history syncing across all devices logged into the same account. This is a standard feature in many apps and should be a priority for ChatGPT.
Here’s a basic implementation approach that your developers can use to integrate cross-device syncing:
Suggested Code Implementation (Python & Firebase/Cloud Firestore Example)
import firebase_admin
from firebase_admin import credentials, firestore
Initialize Firestore DB
cred = credentials.Certificate(“path/to/serviceAccountKey.json”)
firebase_admin.initialize_app(cred)
db = firestore.client()
def save_chat_to_cloud(user_id, conversation_id, chat_data):
  “”“Saves chat data to Firestore for cross-device access”“”
  doc_ref = db.collection(“chats”).document(user_id).collection(“conversations”).document(conversation_id)
  doc_ref.set({“messages”: chat_data})
def get_chat_from_cloud(user_id, conversation_id):
  “”“Retrieves chat history from Firestore”“”
  doc_ref = db.collection(“chats”).document(user_id).collection(“conversations”).document(conversation_id)
  chat = doc_ref.get()
  return chat.to_dict() if chat.exists else None
Example Usage
user_id = “user12345”
conversation_id = “conv67890”
chat_data = [
  {“role”: “user”, “message”: “Hello, ChatGPT!”},
  {“role”: “assistant”, “message”: “Hello! How can I help you today?”}
]
Save chat
save_chat_to_cloud(user_id, conversation_id, chat_data)
Retrieve chat
chat_history = get_chat_from_cloud(user_id, conversation_id)
print(chat_history)
