What Ask Jeeves was, and the three separate endings
Ask Jeeves was the search engine you asked a question, in ordinary English — "How tall is the Eiffel Tower?" rather than eiffel tower height — and which answered in the persona of Jeeves, a cartoon valet borrowed from P. G. Wodehouse. It launched on 1 June 1997, floated on NASDAQ in 1999 at the height of the dot-com boom, bought the Teoma ranking technology in 2001, and spent most of the 2000s as a real, independent, crawling search engine with a genuinely distinctive algorithm.
Three different endings get merged into one in most accounts, and keeping them apart is the whole point of this page.
- The brand ended first. The Jeeves character and name were dropped in the United States in February 2006, briefly reintroduced as a CGI figure on the UK site in April 2009, and retired entirely on 21 September 2016.
- The index ended next. In late 2010 the proprietary search engine was shut down, 130 search engineering roles were eliminated, and web search was outsourced to a third party.
- The service ended last. Ask.com officially closed on 1 May 2026. IAC's statement reads: "As IAC continues to sharpen its focus, we have made the decision to discontinue our search business, which includes Ask.com. After 30 years of answering the world's questions, Ask.com officially closed on May 1, 2026."
Checked on 19 August 2026, the domain serves only a farewell notice — "Every great search must come to an end" — thanking staff and users and noting that "Jeeves' spirit endures." There is no search box and no results. The one-line version: Ask Jeeves started with no index of its own, acquired a genuinely original one in 2001, threw it away in 2010, and the shell it left behind was switched off in 2026. The 2010 decision is the consequential one; 2026 is the paperwork.
Phase one, 1997-2001: editors, not a crawler
The original Ask Jeeves was not a crawler-based search engine. Its natural-language capability was largely a matching layer: a user's question was parsed and matched against a knowledge base of question templates that human editors had built and mapped to hand-picked answer pages. Where no template matched, it fell back to results from third-party engines. The editorially curated architecture is the standard account of early Ask Jeeves and is consistent across the historical record, though no surviving primary technical document was located to confirm the mechanism in detail, so treat the shape as established and the specifics as indicative.
The practical consequence is the one users noticed immediately. Ask Jeeves gave excellent answers to questions somebody had anticipated, and poor answers to anything else. It was particularly well regarded for mathematics, vocabulary and unit conversions — exactly the classes of question where a small number of templates cover a large share of demand. So for its first five years its structural position was not an independent index at all: it was a curated answer layer with borrowed results underneath.
Phase two, 2002-2010: Teoma, and a real alternative to PageRank
On 18 September 2001 Ask Jeeves acquired Teoma for over $1.5 million, and integrated the technology by January 2002. From that point until late 2010, Ask Jeeves and then Ask.com ran its own crawler, its own index and its own ranking algorithm. This is the fact most often lost about the company, and it is why it deserves a serious entry rather than a joke.
Teoma came out of research at Rutgers University led by Professor Apostolos Gerasoulis, with Professor Tao Yang of UC Santa Barbara directing technology development, building on the 1998 DiscoWeb project. Teoma Technologies was founded in April 2000, entered public beta in April 2001, and was fully live in April 2002 — meaning Ask Jeeves bought it five months into the beta, before it had properly launched.
The ranking idea was subject-specific popularity. Rather than scoring a page by its overall link popularity across the entire web, which is PageRank's approach, Teoma identified clusters of topically related, mutually linking sites — communities — and weighted links from within the relevant community far more heavily than links from outside it. A link from a leading cardiology site should count for a cardiology query; a link from a generically authoritative site should not count for as much. Ask.com later branded this ExpertRank, and was still using that name for the Teoma algorithm as of December 2010.
The Teoma brand itself ended on 26 February 2006, when teoma.com began redirecting to search.ask.com; the technology carried on underneath Ask. A Teoma-branded service reappeared in April 2010 returning results similar to Ask's, but that was a skin rather than an independent engine. The crawler operated under Teoma-associated agent names, and no precise canonical user-agent string could be confirmed from a primary webmaster document, so none is quoted here.
Ask also shipped features in this period that predated equivalents elsewhere, notably Smart Answers, structured direct answers placed above the results, and the binoculars site-preview control.
Phase three, late 2010: renting the results
In late 2010, faced with competition it could not match, the company shut down its proprietary search engine, cut 130 search engineering jobs, outsourced web search, and redirected the business toward community-driven questions and answers.
Who actually supplied those results between 2010 and 2026 is not documented in the sources reviewed here. No primary Ask.com or IAC document naming a supplier was located, and the arrangement changed over the years. One large engine is widely named in secondary reporting, but without a dated primary citation it is not stated on this page — and since the site is now closed, it can no longer be checked live. That absence is itself worth noticing: an engine that will not tell you whose index you are searching is asking for a kind of trust it has not earned.
What came after was acquisition rather than engineering. The documented purchases on the Ask.com side are Teoma in 2001, Lexico Publishing Group in 2008, which owned Dictionary.com and Thesaurus.com, nRelate and About.com in 2012, and Ask.fm in 2014. Note what that list contains and what it does not: after 2010 there is no search technology in it at all. Capital went into content properties and a social question-and-answer site. That is a coherent strategy for an advertising business and a terminal one for a search engine.
How it made money, and the distribution problem
Advertising throughout, in three successive forms. Banner and display advertising on the consumer site from 1997, the standard dot-com model that made the July 1999 IPO possible and the 2000 to 2001 crash brutal. Paid search listings once GoTo.com and Overture had proved the keyword auction, sold alongside the algorithmic results and supplemented by syndicated paid feeds — this is the revenue line that made Ask an attractive acquisition. And after IAC bought the company in July 2005, search advertising revenue plus toolbar and browser-default distribution, with revenue after 2010 coming from a share of syndicated search income plus display advertising on owned content.
That third phase is the reason the brand's modern reputation is poor. Ask.com's toolbars and default-search settings were widely reported to arrive bundled with unrelated software, in ways users found difficult to notice and difficult to reverse. This is widely reported but is not documented in the primary sources reviewed for this page, and specific vendor classifications, dates and bundling partners have not been confirmed here, so it is recorded as reputation rather than as established fact. It should not be omitted either: a reference that leaves it out is flattering its subject.
On privacy, Ask has one genuine credit that it is rarely given. AskEraser, released in December 2007, let users opt out of the tracking of their queries, IP address and cookie values, with collected information erased after 18 months unless the setting was kept on. The feature itself required cookies to be enabled in order to work, an awkward but common design constraint of the era. December 2007 put it roughly a year ahead of most mainstream engines' equivalent controls, at a point when search-log retention was a live policy fight in both the United States and the European Union. No independent audit of Ask.com's data handling was located.
The AI irony
Ask Jeeves had no AI features in the modern sense at any point, and the irony deserves stating plainly.
Its entire 1997 pitch — ask a question in plain English, receive a direct answer — is the pitch of every AI search product launched since 2023. Ask attempted it with editorial templates and pattern matching because the technology to do it properly did not exist. The gap between what it promised and what it could deliver is precisely why the brand became a punchline. The same promise, delivered on, is now the industry's centre of gravity.
Ask.com in its final years was sometimes described as an "answer engine," but no primary source confirms any language model, model provider or user-facing AI control on the site, and it closed on 1 May 2026 and can no longer be checked. Nothing in the record supports attributing AI features to it.

What it got right, and the decision that finished it
The question interface was a real usability insight. In 1997 most people did not know how to construct a keyword query, and telling them to type a question instead lowered the barrier to using the web enormously. For a great many people Ask Jeeves was the first search engine they were not intimidated by, and its answers to bounded factual questions were fast and correct while competitors returned ten links.
Teoma was excellent and is badly underrated. Subject-specific popularity is genuinely different from global link popularity, and it addressed a real weakness in PageRank: a generically authoritative site can outrank a specialist one on a specialist query. Ask bought it for a figure that, at over $1.5 million, looks like a rounding error against the $1.85 billion IAC paid for the company four years later. For most of the 2000s Ask.com's results were good — not Google-good on popular queries, but distinctly better than their reputation and better than the brand let most people believe.
What it was bad at was living down 1997. "Ask a question in plain English" set an expectation a template-matching system could not meet. Users asked real questions, got irrelevant answers, and concluded the product was a gimmick. By the time Teoma made Ask a legitimately good engine in 2002, the brand had already been decided: a friendly cartoon valet who could not actually answer your question. The mascot that made it famous made it unserious, and dropping Jeeves in 2006 did not repair the damage.
The 2010 decision to shut the index was the point of no return. Ask.com owned one of very few independent web indexes in the Western world, with a differentiated ranking algorithm and a decade of engineering behind it, and it shut that down and rented results instead. Commercially the choice was defensible: Ask was losing badly on popular queries and syndication revenue was more reliable than engineering cost. Strategically it was terminal. From that moment Ask.com had no product of its own, only a domain name and a traffic-acquisition business.
IAC's stated reason for closing in 2026 was corporate focus rather than competition, which is a tidier epitaph than the company earned. The honest version is that Ask.com had been a domain name attached to somebody else's search results for sixteen years, at exactly the moment when generative systems made "ask a question, get an answer" the most valuable proposition in the industry. It invented that positioning in 1997 and no longer owned a single piece of technology with which to pursue it.
Common misconceptions
"Jeeves was a butler." He was a valet — a gentleman's personal gentleman — to Bertie Wooster in Wodehouse's stories, and Wodehouse was pointed about the distinction. Ask Jeeves' own marketing blurred it and almost every retrospective repeats the error.
"Ask Jeeves understood natural language." Not in the sense people assume. It matched questions against a human-curated knowledge base of templates mapped to editor-selected pages, and fell back to third-party results otherwise. Clever pattern matching plus editorial labour, not comprehension.
"Ask Jeeves never had its own index." Wrong for 2002 to 2010. After acquiring Teoma it ran its own crawler, index and ranking algorithm.
"Teoma was just Ask's name for its algorithm." Backwards. Teoma was an independent search engine out of Rutgers, launched in April 2001, which Ask Jeeves bought that September. ExpertRank is the later Ask.com brand name applied to the Teoma algorithm.
"ExpertRank was PageRank with a different name." No. PageRank scores global link popularity; Teoma's claim was subject-specific popularity, weighting links from within a topically defined community. Whether it worked better is arguable; that it was a different mechanism is not.
"Ask Jeeves was killed by Google." True in the market sense, misleading in the causal sense. It was profitable enough to sell for $1.85 billion in 2005, three years into Teoma. It stopped being a search engine in 2010 because IAC chose to shut the index down, not because it was forced off the web. That was a decision and should be reported as one.
Frequently asked questions
Does Ask Jeeves still exist?
No. The Jeeves name was dropped in the United States in February 2006 and retired entirely on 21 September 2016, and the successor site Ask.com officially closed on 1 May 2026 when IAC discontinued its search business. Checked 19 August 2026, ask.com serves only a farewell notice with no search box and no results. Much published writing, including encyclopedia entries, is still out of date on this.
Did Ask Jeeves have its own search index?
Yes, but only between January 2002 and late 2010. Before that it matched questions against an editor-built knowledge base and borrowed results from other engines. In September 2001 it bought Teoma, an independent crawler and ranking system, and ran it as its own index for eight years. In late 2010 it shut that engine down, cut 130 search engineering jobs and outsourced web search.
What was Teoma and how did it work?
Teoma was an independent search engine built on Rutgers University research led by Professor Apostolos Gerasoulis, with Professor Tao Yang of UC Santa Barbara directing development. Its ranking idea was subject-specific popularity: instead of scoring a page by link popularity across the whole web, it identified communities of topically related sites and weighted links from inside the relevant community much more heavily. Ask.com later called this ExpertRank.
Who owned Ask Jeeves?
It was founded as Ask Jeeves, Inc. in Berkeley, California, conceived in 1996 by Garrett Gruener and David Warthen with original software by Gary Chevsky, and went public on NASDAQ under the ticker ASKJ in July 1999. IAC/InterActiveCorp acquired it in July 2005 in a deal valued at $1.85 billion, and the ticker was retired. It remained an IAC property until IAC closed the search business in May 2026.
Why did Ask Jeeves fail?
It over-promised in 1997 and never escaped it. Asking a question in plain English set an expectation that template matching could not meet, so users concluded the product was a gimmick before Teoma made it genuinely good in 2002. The decisive moment came in late 2010, when the company chose to shut down its own index and rent results instead, leaving it with a domain name and no product of its own.
Where did Ask.com get its results after 2010?
From a third-party supplier that was never clearly documented. No primary Ask.com or IAC source naming the provider was located, and the arrangement changed over the years, so no supplier is named here. One major engine is widely cited in secondary reporting, but the site closed on 1 May 2026 and the claim can no longer be checked against a live page.
Was Jeeves a butler?
No, and Wodehouse cared about this. Jeeves is a valet — a gentleman's personal gentleman — to Bertie Wooster in P. G. Wodehouse's stories, not a butler, who runs a household staff. Ask Jeeves' own marketing blurred the distinction and virtually every retrospective repeats the error. The character was dropped from the US site in February 2006 and retired for good in September 2016.
Did Ask Jeeves have AI answers?
No, at any point. Its 1997 promise of asking a question and getting an answer is exactly what AI search sells today, but it was attempted with editorial templates and pattern matching because nothing better existed. In its final years the site was sometimes described as an answer engine, but no primary source confirms any language model or AI control, and it closed in May 2026 without ever shipping one.
