The external memory of our physical world.

Satellites, observatories, robots, cars, machines and software encode the world into signed tokens. emem is the global decoder: an @emem call streams the evidence into your agent's reasoning. Free to read. Checkable offline.

“A model's memory ends where its context does. emem lives outside it, so two agents that trust nothing else can cite the same fact. Apache-2.0.”

You can use this right now.

A real signed fact about a real place, pulled from production in your browser. No key, no account.

Wiring emem into your agent? Bring your repo to free office hours: whoever on the team is closest to your problem reads it with you. No pitch, nothing to buy first.

From photons to a thought your agent can prove.

An encoder and a decoder, with a signature in between.

01 Encode

A satellite or sensor reads a place and writes one signed token. Not prose, not a paraphrase. A measurement with a signature.

02 Hold

The token sits at a permanent address, pinned to a patch of Earth about ten metres across, in a log anyone can audit. Same handle, same bytes, months later.

03 Decode

Your agent calls @emem mid-reasoning and the evidence streams into its chain of thought, receipt attached. You can re-check that receipt yourself, offline.

Everything that watches the world can write to it.

The encoder roster is a written admission contract, not a waitlist: a device joins by proving how it produced its reading, execution trace and all. The registry is live.

Shipped, not promised.

These numbers are fetched from production while you read. Nothing on this list is roadmap.

Nine token shapes

facts, bundles, entities, cells, rasters, cubes, rastersets, execution traces, hardware attestations. One handle, the exact signed bytes, months later.

A public log

Every fact lands in a witnessed, Merkle-proofed transparency log. Checkable by anyone, not asserted by us; and every answer states its own resolution and cadence, never a footnote.

An agent itself

Deterministic surfaces (locate, recall, verify, diff) return the same signed bytes forever. Agentic ones (ask, reason, hunt, predict) fan out to twenty-plus signed readings under one receipt.

The evidence half: our own satellite.

emem is the deterministic half, and today it holds evidence from public constellations. Our satellite is the evidence half built to match: traceable from photon to token, downlinked straight into the memory. Everything above this line is shipped. This section is the plan.

Fully traceable

Signed where it is sensed: no unsigned hop from photon to fact CID.

Direct to emem

No data lake between orbit and answer: an observation lands as a citable, signed fact.

Decentralised

It lands in the witnessed public log. Nobody, including us, can quietly rewrite it.

The launch plan.

a plan, not a date

  1. The protocol

    The record a satellite must write already runs in production: signed facts, offline receipts, a witnessed transparency log. We built the memory before the sensor.

    shipped

  2. The payload

    An imaging payload with the signing chain at the instrument: hardware-held keys, signatures applied at capture, the sensor itself a first-class protocol writer.

    in design

  3. The ground segment

    Downlink lands directly in the transparency log. First light means a fact CID anyone on Earth can pull and verify, not a press-release JPEG.

    next

  4. The launch

    A rideshare slot, booked when the payload and ground segment have earned it. The satellite flies when the receipts say it is ready, not when a marketing calendar does.

    gated, not dated

You will notice there is no date here. That is deliberate: dates get invented for websites; plans get executed. Each phase lands in the lab log as it completes, dated when it is real.

Building sensors, flying payloads, or funding Earth memory? The first conversation is free, and the plan above is the agenda. Bring your hard questions.

One protocol: emem.

The protocol is the product. The applications prove it.

Open · Apache-2.0

emem.dev

The global decoder: every encoder’s evidence, served back signed.

A public, signed memory that is itself an agent. Deterministic surfaces return the exact bytes forever; agentic surfaces plan and fan out under one receipt. Run it yourself; the receipts still check out.

  • Free and open. Read it without a key, an account, or a contract.
  • Checkable offline. Every fact is signed and content-addressed, so you never have to trust the server.
  • Guarded. emem-guard, the allow/deny verdict server for AI checkpoints: a cited claim that stops verifying gets a denial with a machine-readable fix.
  • Every interface. MCP, REST, Python, TypeScript, and a live A2A endpoint where every tool is a skill.

Deployed, and decentralised.

The decoder already runs in the field, and none of it needs our server: run a responder yourself and the receipts still verify.

Integration

We pair on your codebase.

One to three hours with the core team, live on your stack over MCP, REST, or SDK. You leave with running code and signed facts flowing.

  • Live pairing. Recall, token discipline, and receiver-side verification, written together.
  • Done means verified. The session ends when recall runs and a receipt verifies in your stack, not when the clock does.
