Steven Pruitt spends his evenings identifying errors that astir radical ne'er announcement and making fixes that hardly anyone ever acknowledgment him for. He toils astatine a table successful a municipality location successful Alexandria, Virginia, surrounded by books—the benignant of moving clutter that suggests a agelong narration with insubstantial alternatively than a fetish for screens. And yet his enactment is needfully digital; aft dinner, and sometimes precocious into the night, helium uses his desktop machine to close dates, cleanable up syntax, standardize categories, and occasionally constitute full biographies of radical connected Wikipedia, the escaped online encyclopedia.
Wikipedia is not his employer, of course. Like each editors connected the site, Pruitt is simply a volunteer. “At this point, I won’t accidental I don’t person immoderate tegument successful the game,” helium told me. “But it’s a batch little stakes than a occupation due to the fact that if I get thing wrong, it’s reasonably casual to hole it. I tin hole it myself. I tin bash what I privation to bash connected my ain time.” Still, helium holds himself to immoderate rules: “I bash effort to get successful astatine slightest 1 edit a day.”
Pruitt is forty-two, and works afloat clip arsenic a records-management contractor for the national government. After graduating from the College of William & Mary, successful 2006, helium moved backmost successful with his parents, owing to the outgo of existent property successful Alexandria. In caller years, helium helped his parent attraction for his father. (While I was reporting this story, Pruitt’s begetter died.) In effect, Pruitt—the idiosyncratic who has done much than anyone other to signifier the English-language Wikipedia—lives a beingness that is, by astir outward measures, unremarkable.
According to nationalist tallies, Pruitt has made much than six cardinal edits to Wikipedia and created much than 30 1000 articles. He is wide regarded arsenic the astir prolific Wikipedian successful the full world. (“It depends connected however you’re counting,” helium said. “Different tools number antithetic things.”) In 2017, Time mag included him connected its database of the astir influential radical connected the internet. But extracurricular of a tiny ellipse of editors, researchers, and obsessive readers connected Wikipedia, the designation has hardly registered.
On the site, helium is known by his username, Ser Amantio di Nicolao—a notation to a insignificant quality successful “Gianni Schicchi,” Giacomo Puccini’s comic opera. Pruitt’s involvement successful opera is genuine, but the flourish is misleading. He avoids drama, which means that helium avoids penning Wikipedia biographies of radical who are inactive alive, whenever possible. “I mostly don’t bash a batch successful the realm of existent events,” helium told me. “Not conscionable due to the fact that the stakes are excessively precocious but sometimes due to the fact that there’s truthful overmuch editing going connected on a taxable successful a peculiar infinitesimal that it tin instrumentality maine 5 oregon 10 minutes conscionable to interruption successful with 1 edit.” He prefers biographies of what helium calls “fairly obscure dormant people.”
“They’re settled,” helium explained.
In 2001, Jimmy Wales, an net entrepreneur, and Larry Sanger, a philosopher, launched Wikipedia arsenic an experimentation successful collaborative cognition creation, allowing anyone with an net transportation to contribute. Pruitt archetypal encountered the tract successful 2003, erstwhile helium was inactive successful college. “I didn’t rather recognize what it was,” helium recalled.
For much than a year, helium did not edit astatine all. He would stumble upon Wikipedia pages done hunt results oregon links, and past determination on. Between precocious 2004 and aboriginal 2005, though, his narration to the tract began to change. The encyclopedia had reached what helium described arsenic a captious mass: “There was capable worldly connected the tract that determination was ever thing to do,” helium said. “But it wasn’t conscionable a blank slate.” The quality mattered. A wholly bare encyclopedia was intimidating; a partially filled 1 invited correction and expansion.
Some of Pruitt’s archetypal contributions were related to niche aspects of the Revolutionary War, including an introduction connected 1 of his ain ancestors, a comparatively obscure worker from Virginia. He wrote respective articles connected topics and figures—such arsenic Francis Salvador, the archetypal Jew to beryllium killed successful the Revolutionary War—that would person been improbable to look successful a accepted encyclopedia, and helium watched, with a benignant of amazement, arsenic they remained, becoming imperishable parts of the internet. “At this point, it’s implicit 20 years,” helium said.
Pruitt was actively editing during Wikipedia’s archetypal large maturation spurt. In 2006, its English-language variation reached a cardinal articles, a milestone that signalled some standard and legitimacy. (Wikipedia present exists successful an estimated 3 100 and forty-six languages, with the English variation containing the astir entries.) As the tract became bigger and much prominent, expectations hardened. Editing became little astir authorship and much astir stewardship. “Even if an nonfiction looks complete, honestly, it isn’t ever truly complete,” Pruitt said. Every leafage existed successful a authorities of provisionality, unfastened to revision and dispute.
Over time, Pruitt’s enactment shifted distant from creating caller articles and toward improving existing ones. He standardized categories, repaired references, and corrected tiny errors earlier they crystallized into misinformation. He has inactive seen immoderate of those errors migrate elsewhere connected the internet. “You hole something,” helium said, “and past you’ll spot it amusement up years aboriginal determination else.”
Today, overmuch of Pruitt’s enactment is made imaginable by a specialized editing instrumentality called AutoWikiBrowser. It allows experienced users to marque rapid, semi-automated edits crossed ample numbers of articles, flagging communal problems and applying standardized fixes. Pruitt uses it to revise astatine a standard that wouldn’t beryllium imaginable by analog means: correcting dates, repairing breached links, standardizing citations, and cleaning up formatting crossed thousands of pages. Despite the name, “it’s not automatic,” helium said. “You inactive person to reappraisal each edit.” The instrumentality does not constitute articles oregon marque judgments. It accelerates maintenance.
As I perched adjacent to Pruitt successful his den, helium turned to the machine and began doing what helium calls “mass editing.” He opened up a web-based outer instrumentality known arsenic PetScan, which generates lists of Wikipedia articles by category, allowing him to furniture categories the mode a researcher mightiness harvester hunt terms. “Women scientists” crossed with “19th-century physicists,” for example, produces a database of biographies that acceptable some criteria, revealing pages that mightiness beryllium missing a applicable classification.
The method depends connected intersections. Categories are layered unneurotic until they nutrient a acceptable of pages that tin beryllium worked done successful sequence. Too broad, and the database becomes unusable; excessively narrow, and it returns astir nothing. After Pruitt ran the query for “19th-century women physicists,” a database of articles appeared. From there, helium moved quickly. He opened a biography and checked whether it had been categorized correctly. In immoderate cases, an nonfiction astir a nineteenth-century pistillate physicist had been tagged arsenic a idiosyncratic but not arsenic a physicist. Many entries required lone tiny corrections; others needed much substantive changes. The enactment consisted of tiny decisions made successful accelerated succession, each 1 nudging the encyclopedia person to order.
Wikipedia’s hierarchy is deliberately hard to see. Editors enactment nether pseudonyms. Articles look collectively authored. There are nary bylines, nary salaries, nary masthead. Pruitt was granted administrative privileges, aft different exertion nominated him done Wikipedia’s modular Request for Adminship process, wherever the editing assemblage supported his candidacy. These privileges let him to artifact users and adjacent discussions, but helium is cautious astir what that powerfulness does and does not mean. Wikipedia discourages editors from reverting—“undoing”—one different much than 3 times, careless of correctness. “You tin beryllium blocked for twenty-four hours,” helium said. “It doesn’t substance if you’re right.” He likes the rule. “It keeps things from turning personal.”
Inside Wikipedia, estimation accrues done clip alternatively than visibility, and it “comes arsenic overmuch from longevity arsenic thing else,” Pruitt said. “You instrumentality around. People cognize you.”
Among the radical who instrumentality around—and who marque accordant contributions to the site—are the Wiki-obsessives known colloquially arsenic “super editors.” These individuals are liable for hundreds of thousands, if not millions, of edits. Although determination are much than a 100 and thirty-two cardinal registered accounts connected Wikipedia, a survey recovered that 1 per cent of these users are liable for astir eighty per cent of the site’s content.
Justin Knapp—a forty-three-year-old successful Indiana who has held each sorts of jobs, including moving astatine a pizzeria and astatine a situation hotline—is 1 ace editor. In 2012, helium became the archetypal idiosyncratic to surpass a cardinal edits connected the English-language Wikipedia, earlier Pruitt surpassed him successful full edit number a fewer years later. Knapp told maine that helium doesn’t spot Pruitt arsenic a rival. “It’s not competition,” helium said. “We’re collaborators. We’re colleagues.” Asked whether editors are motivated by metrics astatine all, Knapp was unequivocal: “I truly don’t deliberation the benignant of idiosyncratic who sets astir to walk his escaped clip penning an encyclopedia is truly the benignant of idiosyncratic who cares a batch astir being a large food successful a tiny pond.”
That ethos—low ego, precocious volume—helps explicate however the tract functions. Both Pruitt and Knapp described Wikipedia little arsenic a level than arsenic an ongoing dialog among strangers. Editors coördinate done speech pages—discussion threads attached to each article, immoderate of which tally for years. Disputes accumulate connected speech pages implicit phrasing, sourcing, whether a taxable belongs astatine all, with galore ne'er resolving. A finished Wikipedia leafage reflects a momentary consensus, taxable to revision arsenic soon arsenic idiosyncratic decides to revisit it.
A Wikipedia page’s interior debates often halfway connected matters acold removed from nationalist controversies. “The astir contested topics wrong Wikipedia are not things astir the broader civilization wars,” Wales, the site’s co-founder, wrote successful an e-mail. “Of people determination are hard topics successful the world, but astir of the enactment isn’t astir that. We person robust debates astir adjacent precise obscure matters. That isn’t a problem. It’s what it means to beryllium Wikipedia.”
Those debates unfold nether antithetic conditions. Anonymity shapes that process. Because editors mostly run nether pseudonyms, an statement succeeds not connected the spot of someone’s credentials oregon nonrecreational presumption but connected its grounds and adherence to Wikipedia’s policies. Authority emerges slowly, done repeated participation. “You can’t unit it,” Knapp said. “You gain it by being there.”
Pruitt is not known for winning disputes oregon shaping statement done argument; helium is known for his persistence. He fixes things quietly, avoids unnecessary fights, and doggedly returns to issues wrong an nonfiction that others person near behind. As Knapp said, “I deliberation everyone agrees he’s a bully feline and does invaluable things and is useful.” His standard of enactment mightiness suggest a definite level of power implicit the site—he has altered millions of English-language Wikipedia articles—but the world is much complicated. Wales wrote, “I conscionable looked and this greeting successful the abstraction of 1 infinitesimal helium made 25 edits to region a deprecated template parameter. He looks connected gait to bash hundreds of those successful a time oregon two. That’s incredibly important, but hardly represents immoderate benignant of undue influence.”
That’s not to accidental that Pruitt doesn’t bid an tremendous magnitude of respect successful the Wikipedia community. “We deliberation of him arsenic our No. 1 successful magnitude of edits,” Rosie Stephenson-Goodknight, different ace editor, told me. Stephenson-Goodknight, who is seventy-two years old, began editing Wikipedia successful 2007, aft looking up a defunct American steadfast whose books she collected. “I thought there’d beryllium a Wikipedia article,” she said. “And determination wasn’t.”
Stephenson-Goodknight remembers double-checking the spelling of her hunt term. Nothing appeared. “It was that infinitesimal of clarity,” she said. “There is nary Santa Claus. Mom and Dad are not infallible. Wikipedia does not person an nonfiction astir everything.” So she decided to constitute one. “I started the nonfiction connected Book League of America,” she said. “And it’s inactive there.”
Within a week oregon two, she wrote another. Then another. “I was hooked,” she explained. “It was similar I was calved to bash this. There was conscionable thing astir this researching and penning that conscionable felt similar it was me.” By 2014, she had go a ace editor. Then, successful December of that year, an world insubstantial quantified what editors similar Stephenson-Goodknight had agelong suspected: conscionable 15.53 per cent of English-language Wikipedia biographies were astir women. A fewer months later, Stephenson-Goodknight launched a task called Women successful Red, named for the reddish links that people missing articles. The task focussed connected creating Wikipedia articles astir notable women. It has since produced hundreds of thousands of caller entries.
In 2021, Stephenson-Goodknight was elected to the Board of Trustees of the Wikimedia Foundation, a presumption that she held done precocious 2024. Her tenure coincided with a cardinal displacement successful the relation that Wikipedia plays connected the internet. As the tract entered its 3rd decade, and artificial-intelligence algorithms grew bare for information to larn on, Wikipedia articles were nary longer conscionable read; they were scraped, summarized, licensed, and folded into systems designed to reply questions elsewhere. In different words, Wikipedia had go infrastructure.
Pruitt was vaguely alert of the alteration earlier helium afloat grasped its implications. “Friends successful tech would notation it,” helium recalled. “They’d say, ‘You cognize Wikipedia is being utilized for this now.’ ” He did not travel developments successful A.I. closely. “I don’t recognize fractional of what Silicon Valley does,” helium said. What helium does recognize good is notation works.
In October, 2025, erstwhile Elon Musk’s institution xAI launched Grokipedia, an A.I.-generated encyclopedia that is often compared to Wikipedia, Pruitt approached it the mode helium would immoderate caller compendium. He searched for articles connected subjects helium knew well, specified arsenic nineteenth-century opera singers. “They weren’t there,” helium said.
But what unsettled him was not what was missing from Grokipedia but what was somewhat off. “Nothing was precisely wrong, but it was conscionable little close than I would person made it,” Pruitt said. He described speechmaking an introduction that repurposed accusation from Wikipedia portion subtly distorting it. In 1 instance, the introduction summarized portion of a person’s beingness successful a mode that struck him arsenic careless, describing a seven-year play arsenic “brief.” “I don’t deliberation that’s brief,” helium said.
The problem, arsenic Pruitt saw it, was not the errors themselves—there are plentifulness of mistakes connected Wikipedia—but alternatively wherever the work for those errors lay. “Wikipedia tin beryllium fixed,” helium said. Errors are corrected publicly, and editors tin statement them. Responsibility is shared, and each edit tin beryllium traced. Grokipedia, connected the different hand, and A.I.-generated accusation much broadly, obscured the information-gathering process. It generated substance that sounded authoritative without revealing precisely however it arrived there. “It sounds right,” helium said. “And that’s worse.”
Inside Wikipedia, the effect was pragmatic. Editors clarified existing policy. The usage of ample connection models to make contributions oregon rewrite contented became grounds for blocking users. The determination wasn’t simply ideological. “You can’t collaborate with thing that doesn’t instrumentality responsibility,” Pruitt said. Responsibility, connected Wikipedia, meant that each edit was logged, each disagreement archived, each alteration reversible.
Still, Wikipedia’s prohibition connected A.I. doesn’t mean that A.I. is prevented from reusing contented connected Wikipedia. Multiple A.I. companies person acknowledged that they trust connected Wikipedia arsenic a root of grooming information and notation material, citing its standard and accessibility. The site’s contented is openly disposable nether a Creative Commons license, a diagnostic agelong intended to promote acquisition reuse but 1 that besides made it particularly legible to automated systems. Wikipedia became a foundational substance for machine-learning models designed to summarize and reply questions utilizing accusation drawn from different online sources. Analyses of A.I. outputs suggest that Wikipedia accounts for astir a 4th of cited sources, according to information compiled by Semrush, a search-optimization company, with the Wikimedia Foundation, the nonprofit that hosts Wikipedia, announcing earlier this twelvemonth that Amazon, Meta, Microsoft, Mistral AI, and Perplexity had joined its commercialized work for large-scale entree to Wikimedia data.
Wales, Wikipedia’s co-founder, doesn’t spot this arsenic a large alteration successful the mode that the tract was already functioning. In his view, the narration betwixt Wikipedia and the broader accusation ecosystem has ever been cyclical alternatively than hierarchical. “Wikipedia informs journalists who past pass billions of people,” helium wrote. “Wikipedia informs academics who past pass billions of people. And the journalists and academics (and artists and poets and everyone else!) pass Wikipedia. We’ve ever been a layer.”
For Wales, the cardinal question is how A.I. is used. “The cardinal for maine is ‘human successful the loop,’ ” helium wrote. “If you usage AI successful your work, that tin beryllium bully oregon bad—it’s up to you to bash it well. We don’t judge that astatine the existent time, AI is anyplace bully capable to straight constitute for Wikipedia without precise cautious quality oversight.”
Midway done Wikipedia’s twenty-fifth year, the tract remains babelike connected quality volunteers: editors similar Pruitt, who are consenting to walk thousands of hours making meticulous changes, and who importune that they could halt astatine immoderate time. “I could,” Pruitt told me—stop, that is. “If I wanted to.” The connection wasn’t defiant; it was matter-of-fact. ♦
