Found note #219 in memex. The first release will include the landing page and enquiry form. We’re leaving booking functionality for a later phase to keep the initial release small. We’re aiming for Friday, subject to your approval of the copy, but the delivery date isn’t confirmed yet.

Guardrails and memex
Your AI proposes. You decide what stays.
AI can be wrong and sound exactly as certain as when it’s right. No better model fixes that; a person in the loop does. That person is you: read it, change what needs changing, approve.
Nothing lands without you.
Your memex inbox is where you decide. See what your assistants want to add or change, then approve or reject it. The library takes the shape you give it.
Every change is reversible.
Every edit is saved. Open a note’s history, see what changed, and restore any earlier version. A note you delete stays restorable for thirty days.
Plain files, just words.
Every note is plain Markdown and exports as a file any program can open, now and in twenty years.
Bring it in, take it out.
Bring in what you already have, take out everything you’ve built. One click in either direction.

Questions people actually ask
Who is memex for, and how much setup is involved?
Anyone who works with AI and wants a notebook made for it: one your assistant writes in while you talk, and you read, approve and come back to. Plans, research, client briefs, a family trip: whatever you work out with AI and don’t want to lose or explain again.
You don’t need a photo studio to crop a family picture, or a complex memory system to keep notes with your AI. Use your usual AI chat. Ask your assistant to read your notes, save what you work out, and suggest updates when things change. Open memex to review and edit them yourself.
You do not need to code. Allow a few minutes to follow the connection guide in your assistant’s settings, including its permissions. The requirements depend on the assistant and its plan. After that, ask your usual assistant to read or save notes while you work.
How does an assistant use a skill note?
A skill note tells an assistant how you want a particular repeating task done. You might write that a decision note must include the reasons and links to the evidence. Save that instruction as a note and tag it skill. Connected assistants can find it in memex, and you can ask them to use it for a particular task. You can edit or delete your skill notes at any time.
Doesn’t ChatGPT already remember things about me?
They all do, each inside its own system, and that memory stays behind when you switch. With all the complexity of modern AI memory solutions, in most cases what your AI needs is a simple notebook you both can read and write to. Memex is that notebook: one set of notes every assistant you connect can read, written in your words, with you deciding what goes in. Connect the next assistant and it reads the same notes. Nothing to export, nothing to explain again.
How is memex different from other AI memory products?
Most are professional tools: built for developers and teams, with APIs, automatic extraction and plans to match. If you need that, they do it well. Memex covers the everyday part, a notebook your assistants read from and write to and you can open and correct, and stops there.
Memex is not a better memory product, and doesn’t try to be one. If you already use one, keep it: it remembers you and your conversations, while memex keeps what you made in them, as notes you can read and correct. Both can be available to the same assistant.
Why not just use Notion or Evernote?
Those are notebooks you write in. Memex is a notebook you and your AI write in together: your assistant saves a note while you are talking to it, your other assistants read that note later, and you turn up to approve or reject what was saved. Every note names who wrote it, and by default nothing an assistant writes counts until you have said so. That inbox is the difference.
Will this make more work for me?
Only as much as you put in. Your assistant does the writing, and it is fine to let held notes sit until you have a minute.
A knowledge base does take the shape of the person who keeps it, though. Your part is the verdict: what is true, and what stays. Spend a minute on that per note and everything you build on it is better for it.
Who can see the information I save?
Notes are private to your account and stored on Amazon’s infrastructure in the US. Connected assistants can read them. Memex also sends note text to OpenAI for meaning-search indexing and summaries, so saving here can involve a provider you may not use for chat. Read the privacy policy before saving sensitive material, and keep passwords and API keys elsewhere.
What if I want to leave?
Take everything. One click downloads every note as Markdown, links included, to open in any program or import into self-hosted memex. No fee, no request, no format of ours to decode.
Can I run memex on my own computer?
Yes. Memex comes two ways, with the same notes and the same review inbox. Neither is the better one; they suit different needs.
