Question 1

How is this different from AI memory?

Accepted Answer

Memory is implicit. The agent decides what to keep and what to pull back in, and you usually find out only when it acts on something you never meant to save. Conversations are messy: you argue both sides of a question, change your mind, think out loud, and memory banks those half-positions as if they were conclusions, stripped of the context that made them provisional. A space is explicit. Nothing is kept unless you agree to it, and what is kept is the state of your understanding — what you concluded, not every assumption you tried on the way there. You can read all of it, change it, or delete it.

Question 2

Do I have to write it all down myself?

Accepted Answer

No. It gets written as you work: the AI proposes what is worth keeping, and you confirm. The point is that you see it happen — nothing lands behind your back.

Question 3

Who can see my space?

Accepted Answer

Only you, until you say otherwise. You can share a single note, a folder, or the whole space — with named people or a link. Everything you have not shared stays private.

Question 4

Which AI can I use?

Accepted Answer

Keeper is built in and knows your space from the first message. Claude Code, MCP-capable editors, and your terminal all work against the same space, so it does not matter which one you have open.

Question 5

Do I need a vector database or a server for this?

Accepted Answer

No server, vector database, or always-on process. IdeaSpaces on the web requires nothing to install. Local agent integrations require Node.js and git, and run only when your agent runs. Locally, your AI finds things the way you would: folder names, summaries, then the file it actually needs. The structure does the work, which is why a space stays plain markdown you can open in any editor. On the hosted side, search is our problem, not yours.

Question 6

Is this just another notes app?

Accepted Answer

At the surface, yes — deliberately. Notes are the form people are already comfortable with: you read them, you write them, and you always know where you are. Underneath, the representation is richer than anything you would want to keep up by hand — how ideas connect, what a folder is for, how the work gets done here. An AI navigates that easily, and does most of the capturing for you. Every wave of technology brings a medium that fits it: the page for print, the site for the web. This is the one built for AI to inhabit, with notes as the part you see.

Question 7

What if I want to leave?

Accepted Answer

Take it with you. A space is ordinary markdown with full history — copy it to a drive, host it yourself, or open it in any editor. It is git underneath, though you never have to see it, and the format is open and documented.
