'''Molecupedia''' is an online encyclopedia written and published by [[Molecular Reality Corporation]], an American company that builds instruments for detecting single molecules and particles as they pass through small holes. Its subjects are the company itself, the science of counting things one at a time through holes, the other companies in that field and the history behind both. Since October 25, 2026, its article on the company has been the front page of the company's websites, where it replaced a page that showed a single sentence. Its tagline is "The Encyclopedia of Very Small Things".

Molecupedia copies the layout and typography of Wikipedia, credits the software it borrows them from, and has no connection with Wikipedia or the Wikimedia Foundation. Unlike Wikipedia, it cannot be edited. Its Main Page welcomes readers to "the free encyclopedia that no one can edit", where Wikipedia's welcomes them to "the free encyclopedia that anyone can edit".

== History ==
=== The quest ===
The company organizes its work as a role-playing game, [[Epic Quest Bio]], in which tasks are quests and completing one earns [[Experience points (Epic Quest Bio)|experience points]] (XP). One quest on the board, titled "MRC wikipedia page" and worth 500 XP, reads in full: "Make an awesome (and accurate) wikipedia page about Molecular Reality Corporation." By October 2026 it had been switched off.<ref name="p14">{{cite news |title=A Biotech Run as a Role-Playing Game |work=Brownian Business Daily |author=Harriet Quill |date=2026-10-21 |url=/press/brownian/2026/10/21/gamified-management}}</ref> The same board valued a tweet that "Doesn't have to go viral, just has to be a banger!" at 500 XP as well.<ref name="records">{{cite web |title=Company records |publisher=Molecular Reality Corporation |date=October 2026}}</ref> The largest quest on the board, "Sequence DNA with an ss-nanopore", is worth 9,900,000 XP, which is 19,800 times as much: "This is a holy grail, and the XP represents a pool (unless, somehow, a single player does it!)"<ref name="records" />

Wikipedia's guideline on conflicts of interest, which covers writing about one's employer, calls such editing "strongly discouraged". Molecupedia was published on the company's own domains instead.

=== Launch ===
From August 19 to October 24, 2026, visitors to molecularreality.com and epicquest.bio saw a single line, "everybody's racing to build the brain, we're building the eye.", and a twelve-second video of an eye with a protein emerging from its pupil.<ref name="splash">{{cite web |url=https://molecularreality.com |title=Molecular Reality Corporation |publisher=Molecular Reality Corporation |date=2026-08-19}}</ref> At 01:17 UTC on October 25, 2026, the company replaced that page with Molecupedia's article on itself, an entry of more than 6,000 words with more than sixty references, two maintenance banners and a section called Status.<ref name="records" /> The same page answers at demonpore.com and keltar.ai, the company's two other domains; as its guide puts it, "One website wears several addresses."<ref name="faq">{{cite web |url=https://molecularreality.com/FAQ |title=Keltar's Field Guide to Molecular Reality |publisher=Molecular Reality Corporation |date=August 2026}}</ref> The previous front page stayed online at a separate address.

At launch most of the article's links pointed to pages that did not yet exist and showed in red. Its history and its timeline followed within the hour. The company published the other articles over the following hours and days, and each link turned blue when its page went up.<ref name="records" /> By the latest count it has {{NUMBEROFARTICLES}} articles.

== Name and identity ==
The name joins "molecule" and "encyclopedia", in the way that "Wikipedia" joins "wiki" and "encyclopedia". The logo is a molecule of buckminsterfullerene, the 60-atom carbon cage of 12 pentagons and 20 hexagons, drawn from the coordinates of its atoms. Three faces are missing at the top, so that the cage is open, and its faces carry the symbols of units and constants, among them ℏ, Da and ''kT''. One hexagon is printed in the company's green and carries the letters MR.<ref name="records" />

Some articles carry boxes that send readers to sister projects, Molecule Commons for media and Moleculary for definitions. Neither exists.

== Content ==
Molecupedia's articles fall into four groups: the company, with its history, instruments, games and characters; the science of nanopores and resistive-pulse sensing; the companies and laboratories in the field, including the company's competitors; and the history of science, from [[Antonie van Leeuwenhoek]] to [[Jean Perrin]], whose experiments on Brownian motion persuaded physicists that molecules exist. The phrase in the company's name is older than the company: Mary Jo Nye's 1972 study of Perrin's work is titled ''[[Molecular Reality (book)|Molecular Reality]]''.<ref name="nye">{{cite book |last=Nye |first=Mary Jo |title=Molecular Reality: A Perspective on the Scientific Work of Jean Perrin |publisher=Macdonald |location=London |year=1972 |isbn=0444195963}}</ref>

Facts about the company come from its own pages, its open repository, its videos, its posted messages, its records, its patent and the registration records of its domains. Facts about science come from published papers, cited with their digital object identifiers. The rules are set out at [[Molecupedia:About]], and every page ends with the same notice: "Molecupedia is a parody of an online encyclopedia, written and operated by Molecular Reality Corporation, a for-profit company that would like you to know this." Many articles also cite seven news outlets, from ''The Picoampere'' to ''Ludicious'', which publish only on the company's website. The company writes them too, and holds them to the same rule. Their forerunner was a single mock magazine article of November 2025 by an invented correspondent, [[Hypatia Morrison]], which carried the note "This is not a real news article, but almost everything in it is true."<ref name="records" />

On the company article, two maintenance banners flag a conflict of interest and promotional wording, and {{Tl|Peacock inline}} follows two of its own phrases. The policies on [[Molecupedia:Neutral point of view|neutrality]] and [[Molecupedia:Conflict of interest|conflicts of interest]] explain why the banners stay.

== Accuracy ==
Where the company's own statements and published science disagree, Molecupedia gives both and cites the science. A March 2026 post by the founder says that "Nobody outside the corps calls it molecular streaming yet"; the [[Molecular Reality Corporation|article on the company]] quotes the post and then cites a 2019 paper in ''Nature'' titled "Molecular streaming and its voltage control in ångström-scale channels".<ref name="mouterde">{{cite journal |title=Molecular streaming and its voltage control in ångström-scale channels |journal=Nature |volume=567 |pages=87 |year=2019 |doi=10.1038/s41586-019-0961-5}}</ref> That article reports the company's best machine-learning result, 85.4 percent accuracy against 81.0 percent for a retrained [[QuipuNet]] network, together with the fact that it has not been published. It gives the precision with which the company can position its sliding membranes, better than 5 nanometers, apart from the size of the opening, where apertures below 15 nanometers remain a target. A company chatbot's statement that the [[demonpore 64]] was "housed in a repurposed Atari 2600 case" appears with {{Tl|Better source needed}} after it.

After the company's own records, the source that the company article cites most often is [[Keltar's Field Guide to Molecular Reality]], which is written in the voice of a felt puppet.{{efn|The guide's motto is "Real science today. Dreams flagged as dreams. Story flagged as story."<ref name="faq" />}}

== Editing ==
No one can edit Molecupedia. Each page has a "View source" tab where Wikipedia has "Edit", and the source it shows is the company's. Discussion takes place on talk pages, among editors with invented usernames such as PicoampPedant and DwellTimeDave, who argue about real facts; the [[Talk:Molecular Reality Corporation|talk page of the company article]] has closed a merge proposal, a request to rename the company "The Eye" and a request to stop calling a desktop instrument handheld. Page histories list edits by the same invented editors.

== Design ==
The skin reproduces Vector 2022, a skin of MediaWiki, the software that runs Wikipedia, and every page credits it in its footer under the GNU General Public License, version 2 or later.<ref name="gpl">{{cite web |url=https://www.gnu.org/licenses/old-licenses/gpl-2.0.html |title=GNU General Public License, version 2 |publisher=Free Software Foundation |access-date=2026-10-25}}</ref> Pages are written in MediaWiki's markup language and converted to static web pages before publication. Each article opens with the line "From Molecupedia, the encyclopedia of very small things". The encyclopedia has a phone layout, a night mode, a search box and a link to a [[Special:Random|random article]].

== Reception ==
Four days before the launch, ''Brownian Business Daily'' described the switched-off quest in an article on the company's game-based management. Its account ended: "The quest for a wikipedia page about the company is worth 500 XP. It is switched off."<ref name="p14" />
