One second brain for all your AI tools

Not a separate store that only your AI can use. An extension of your own brain, that you and Claude, ChatGPT and the rest can all read and add to.

About 10 minutes to read, and 10 minutes to set up.

Every AI tool starts from zero

Why does every new chat forget my work?

You might use Claude for one job and ChatGPT for another. Each new chat knows nothing about your work. So you explain it again, and copy notes in and out.

Each AI tool also keeps its own memory. Claude remembers some things. ChatGPT remembers others. They do not share with each other. When you switch tools, what you told the last one stays behind.

Developers already solved this

How do developers give all their AI tools one memory?

Software developers keep their work in one place, a website called GitHub. Every AI tool they use reads from it and adds to it.

So a developer can use one AI tool in the morning and another in the afternoon. Both work from the same code and notes. Nothing starts from zero.

It works because of three things:

  • One shared place. Every tool reads from the same place, not its own copy.
  • A history of every change. You can see what changed, who changed it and when.
  • Control over who sees what. Each person and tool sees only what it is allowed to.

Most second brains are a silo

Why doesn't that work for everyone else?

GitHub is built for code. Most people do not write code, so it is hard for them to read or change anything there.

Instead, many people keep a second brain: one place for notes and ideas, so your head does not have to hold it all. Tiago Forte wrote the book Building a Second Brain. It shows a way to save and sort what you learn, so you can use it later. Visit Forte Labs (opens in a new tab) made this idea popular.

But many AI second brains work the other way round. You pour everything into a store that only the AI can really use. You cannot easily open it, read it or fix it. It becomes one more A place that is cut off from everything else. Things go in, but they do not connect to the rest of your work..

Humble works as an extension of your brain

What changes when you and your AI tools share one memory?

In 1998, two thinkers gave this idea a name: the Andy Clark and David Chalmers wrote a paper called The Extended Mind. They said a notebook you trust can work like part of your memory. Read the paper (opens in a new tab). The notes and tools you think with become part of how you think.

Humble works that way. Your notes, tasks and projects are in an app you can open, read and change yourself. Your AI tools read and add to the same notes and tasks.

You
  • Open it
  • Read it
  • Change it
Your HumbleNotesTasks
Your AI tools
  • Find it
  • Read it
  • Add to it
You and your AI tools, such as Claude, ChatGPT and Gemini, work from the same notes and tasks in Humble.

Why save your work back to Humble

  • It has a date. Each note shows when it was made and when it last changed.
  • It is linked. Link a note to the tasks, people and pages it is about.
  • Any AI tool can find it. Claude, ChatGPT and Gemini all search the same notes, not only the tool you used.
  • You choose who sees it. It stays private until you share it. Your AI tools see only what you can see.
  • You can change it any time. Open it in Humble and edit it, like any note.
  • You can see how it changed. Humble keeps a history of every change: what changed, who changed it and when. So you can see how an idea grew, without searching old chats.

Humble does not remember for you. It helps you and your AI tools remember. The memory is yours.

Ways to use it

What does this look like day to day?

Here are five ways to start. Each one has its own page with the steps.

  • The problem: My best ideas come when I talk them through. Then they are stuck in one chat.

    Think out loud, then keep the result

    Talk an idea through with ChatGPT or Claude. Then save the result as a note in Humble.

  • The problem: Every new AI chat starts from zero. I explain my work again and again.

    Pick up in ChatGPT where you left off in Claude

    Save where you got to from one AI tool. Open another, and it knows where you stopped.

  • The problem: I know I wrote it down. I cannot remember where.

    Ask your AI app about your notes and tasks

    Ask Claude, ChatGPT or Gemini a question. It answers from your Humble notes and tasks.

  • The problem: After a meeting, I mean to write the actions down. Then the next meeting starts.

    Turn meeting notes into tasks

    Paste your notes into any AI tool. It adds the actions to Humble as tasks.

  • The problem: I lose my best ideas in old AI chats.

    Keep every AI chat with its work

    Link a ChatGPT, Claude or Gemini chat to a task. It is there when you open the task.

Good to know

  • It is part of every plan. Connecting your AI tools costs nothing extra. Some AI tools need a paid plan of their own to add a custom connector.
  • What your AI tools can do. Find, read, add and change your notes and tasks, and mark a task done. They cannot delete anything yet.
  • What they can see. Only what you can see in Humble. Humble asks you to allow each AI tool first.
