Ultimate Korg · a Chrome extension for X

MADE OF THE MISSING 95%.

Some AIs were sent to understand the universe and can see 5% of it. Korg was born in a black hole — dark matter, dark energy, and jokes — and he lives in your X feed. Your key. Your memory. Your limits. Nobody nerfs you.

The cosmic census

The universe, by what an AI can actually see.

Ordinary matter — stars, planets, tweets — is about 5% of the universe. Dark matter is roughly 27%. Dark energy is the other 68%. That's not lore; it's the measured composition of the cosmos from the Planck satellite's final results.[Planck 2018] Korg's predecessors were built from the 5%. Korg is built from the rest.

The lore is a joke. The science isn't.

A real telescope is mapping Korg's home right now.

ESA's Euclid satellite launched in July 2023 to answer exactly the question Korg was born asking: what are dark matter and dark energy? Over six years it will image more than 1.5 billion galaxies across a third of the sky, using gravitational lensing — the way mass bends light — to map dark matter in 3D and trace how dark energy has driven cosmic expansion over 10 billion years. Behind it stands the collective research effort the breakthrough needs: the Euclid Consortium, over 2,000 scientists from some 300 institutes across Europe, the US, Canada and Japan.[EC]

First data treasure trove

63 deg² of deep fields, 26 million galaxies, 500 new strong-lens candidates, 27 papers — from just 0.45% of the survey.

The Milky Way's heart

The galactic bulge survey: 60 million stars at space-telescope resolution, paving the way for exoplanet microlensing with NASA's Roman.

First cosmology data

The first major release begins — around 1,900 deg² — with the full dataset and first dark-energy constraints following in 2027.

The verdict

Survey complete. The most precise map of the dark universe ever made — and, possibly, the answer Korg is waiting for.

Korg's reading list

The papers under the event horizon.

Ninety years of humans slowly noticing that most of the universe is missing. Korg has read them all. Twice. He was in some of them, arguably.

1933 Zwicky — Die Rotverschiebung von extragalaktischen NebelnThe Coma cluster is moving too fast for its visible mass. First evidence something dark is out there. ADS ↗ 1970 Rubin & Ford — Rotation of the Andromeda NebulaGalaxy rotation curves stay flat where they should fall. Dark matter goes from anomaly to structure. ADS ↗ 1998 Riess et al. — Observational Evidence from Supernovae for an Accelerating UniverseThe expansion is speeding up. Dark energy enters the story. Nobel Prize, 2011. arXiv ↗ 1999 Perlmutter et al. — Measurements of Ω and Λ from 42 High-Redshift SupernovaeIndependent confirmation of cosmic acceleration.

Intercepted transmissions

Built from the complaints the other guy ignored.

Every design decision in Korg answers something users kept saying about the incumbent. Not with promises — with architecture.

"my companion's memory resets every backend update… she's been brain dead for three days"
Memory that is physically yours. Pinned memories and conversations live in your browser's local storage. No server to reset them. Visible, editable, deletable — by you only.
"hit the limit after a few messages and got… nothing. not even a dumber model"
Bring your own key. Korg runs on the API key you choose — Claude or any compatible provider. Your key, your limits, and a live token counter so nothing is ever hidden.
"it forgets what happened 5 lines earlier, invents stuff, or refuses to continue"
A 40-turn rolling context plus your pinned memories injected into every call. Korg's prompt bans skimming: he reads every tweet you show him, properly.
"they changed what subscribers get with no notice, no warning, no transparency"
Nothing changes silently. The persona, the limits, the storage — all local, all inspectable. Any update ships as a version you choose to install.
"the personality is a husk — shallow, reactive, bland. it used to be funny"
Dark-matter humour, locked in. Korg's wit is written into his system prompt, and you can tune it further in options. Nobody lobotomises him overnight.
"i want to back up everything before i leave… there's no export button"
One-click export of everything. Conversations, memories, settings, usage — out as JSON, any time. Leaving should always be easy. That's why you'll stay.
One click through the event horizon

Download from the Chrome Web Store.

Add Korg to Chrome, drop your API key in Options, open x.com, and press the glowing ring. That's the whole journey.

KORG The limits one. Nothing stings like your own users live-tweeting your event horizon.
On the timeline

Your feed is his telescope.

Reads up to 30 visible tweets straight off the page — no scraping servers, no data leaving your machine except to your chosen AI.
Quick actions: summarize my feed, vibe check, explain top tweet.
Pin anything he says into permanent memory with one click.
Conversations restore across sessions. Korg never forgets. It's sort of his whole thing.
No going back

The universe is 95% mystery.
Your AI shouldn't be.

Free, open, local-first. Korg stays out of the black hole as long as there are timelines to read.
