Tools to make ChatGPT and Claude know the same things — which one fits you?

There are two kinds: tools that remember your chats automatically, and a shared journal the AI writes your decisions and finished work into without being asked. Which fits depends on what you want to carry over.

Which tool fits you?

Answer a few questions about how you work. The answer comes after.

Which AI do you use? (pick all that apply)

Does this sound like you?

I have more than one Gmail (work and personal, or several companies) and want the AI to handle them together.
I'm in more than one Slack workspace.
I use several AIs and do not want to repeat the same explanations
My email is Outlook / Microsoft 365.
I want the AI to remember things without being asked (what we decided, past conversations).
I'm a developer and happy to run my own server.

Good to know

ChatGPT's and Claude's own memory stays inside each of them.
To bring in past chats, pick a tool that imports them (MemoryPlugin says it does).
Into AccountHub's journal the AI writes what you decided and the work it finished (AccountHub instructs it to, without you asking). It sits next to your Gmail and Slack connections; whole conversations and email or Slack content are not saved into it automatically.
