MEMENTO is introduced through an opening statement and six short scenes. Scroll, or move through the text, to reach the guided demo. The Memory Sphere has an equivalent record list after the scenes.
Memento
The end of AI beginswith what it remembers.
A public archive of lived human memories—built to replace machine-made defaults with evidence of how people actually feel, remember and behave.
01 · What it starts with
A system begins withwhat it has been taught.
Its memories become defaults.Its defaults become behavior.
Drag to look around. Click a memory to preview it. Colour cards are documented memories; grey fragments are machine-made placeholders.
02 · Lived experience
Memento gives livedexperience a placein that memory.
Not a prompt. Not a persona.Something that happened to someone.
Dated, declared by the person who lived it, and given a proposed address.
03 · How a memory enters
Each memory is received, reviewed, and given an address.

04 · What changes Simulation
Accepted memorieschange how the systemweighs a situation.
A demonstration of the proposed effect. The public archive works today; the behavior model does not yet run.
05 · Capacity and rules
3,690 placesto begin.
The rules and the historystay visible.
- Now
- 3,690 addresses · one human memory replaces one synthetic memory
- Proposed
- A larger capacity is documented in Capacity and Protocol. It is not active.
- Rule
- No expansion happens automatically. Every change must follow a published, verifiable rule.

Replacement selection
Ref C·1 · rev 0.3Which synthetic address disappears is the part people will suspect, so it is a public rule with no operator input:
Selection · pseudocode
seed = H(previous_state_root ‖ recordHash(new_memory))
candidates = all addresses where kind == "synthetic" // within the current capacity version only
weights = [ w(cell) for cell in candidates ] // published: similarity of the synthetic text to the new memory
index = sample(candidates, weights, seed) // deterministic given seed
erase(index); write(index, new_memory)The weighting favours synthetic addresses whose text most resembles the incoming human memory, so a real memory about a kitchen tends to erase a generic memory about a kitchen. Anyone with the previous root and the new hash can recompute the choice.
Influence is a separate, measured quantity: how much a human address changed the mind's output on the measured axes. It never affects selection. The Index shows it so people can see which memories mattered.
