Keeper
Keeper is an AI-assisted matchmaking service for people who intend to marry. Its models rank large candidate pools on stated preferences and psychometrics, then a human matchmaker vets every introduction. One curated match at a time, no subscription.
What is Keeper?
Keeper is a matchmaking service operated by Keeper Dating Inc., a Delaware company founded in May 2022, and it is careful to say what it is not: neither a swipe-based dating app nor a conventional matchmaking agency. The stated mission is to give everyone on Earth the opportunity to marry the right person, and the product is built around that single outcome rather than around engagement.
The mechanism has two halves. Members build a deep profile, from which Keeper derives structured compatibility signals, psychometric scores and profile embeddings stored in a vector database. Language and vision models then rank large candidate pools against stated preferences and relationship science — the vision side exists to check appearance criteria on photos, and the algorithm mixes in-house models with third-party ones, including OpenAI's GPT API. The second half is human: a matchmaker reviews every candidate by hand before an introduction happens. The woman sees the match first; if she passes, the man never sees her profile and receives anonymous feedback instead. Only a mutual yes produces an introduction, and members receive one curated match at a time.
The claimed results are specific. Keeper reports that 1 in 10 first dates has led to marriage against 1 in 1,000 on the most effective apps, that women accept 53% of offered matches and men 65%, and that 37% of matches reach a first date. Its machine-readable brief adds, as of 14 October 2025, roughly 63% mutual acceptance. Signups are given as 1.6 million. All of these are self-reported.
Three products sit deliberately apart from the core service: a free Standards Calculator that computes what share of the US population meets your criteria from Census and CDC data without storing input, Photo Testing which returns private 1-to-10 ratings from a selected audience, and Keeper Labs, a research programme giving vetted researchers de-identified match data and in-product experiments. Development is visibly active — Keeper V3 landed in June 2026 with a dynamic question feed and live match previews — but the service is genuinely available only in the United States, Canada and the United Kingdom, in English, to adults over 18.
What it does
- Rank large candidate pools with AI, on structured compatibility signals, psychometrics and profile embeddings held in a vector database
- Have a human matchmaker vet every candidate by hand before any introduction is made
- Capture partner preferences of any kind, in your own words, and rank them by priority
- Show the woman the match first, then the man if she is interested, and introduce only on a mutual yes
- State, before you meet, which of your stated preferences the match satisfies and which it does not
- Rate dating photos from 1 to 10 with a target audience you choose, with written comments and demographic breakdowns
- Work out what share of the US population meets your stated standards, from Census and CDC data, with no sign-up
When to use Keeper / When not to
A quick filter to help you decide if Keeper is the right fit.
When to use Keeper
- Adults over 18 who are explicitly looking for marriage rather than more dating, and who accept being screened for that intent
- People with long and very specific partner criteria: the homepage shows preference lists running to +23, +74 and +92 items
- Singles worn down by swiping, who would rather receive one vetted introduction than manage a queue of conversations
- Members with no budget, since the free plan gets you matched with paying members without paying anything at all
- Academic and industry researchers, who can reach de-identified match data and in-product experiments through Keeper Labs
When not to use Keeper
- Anyone after casual dating: Keeper states that casual daters are banned and that seeking hookups gets you removed
- People outside the United States, Canada and the United Kingdom, where Keeper concedes its network is still limited
- Non-English speakers and anyone under 18: the service runs in English only and 18 is a hard, verified minimum
- Buyers who need a published price, since the Marriage Bounty amount varies case by case and is never displayed
- Developers and mobile-first users: there is no public API and no native iOS or Android app, only a browser app
How to use Keeper
A typical end-to-end flow, from setup to results.
- Create an account from the Get matched button; Google sign-in and passkeys are both supported
- Work through the Keeper V3 question feed, one prioritised card at a time rather than long questionnaire modules
- Declare your partner preferences, including the very specific ones, then rank them by priority
- Rate photos so the system learns your physical type, which is now part of the core matchmaking loop
- Take the Big Five personality test and complete phone verification
- Watch the blurred live match previews and estimated match percentages update as you answer
- Let the AI rank the pool and a human matchmaker vet the shortlist by hand
- If you are a woman, review the match first; the man sees you only if you are interested
- On a mutual yes, Keeper makes the introduction and contact details are exchanged
- Give feedback after the date, and pause or edit your profile from the app whenever you want
Pros & Cons
Pros
- Incentives are aligned and capped: no subscription, and the main revenue only arrives if you reach a relationship milestone
- The free plan is real — you can be matched with paying members without paying anything
- Every introduction is checked by a human, so the AI ranks but does not decide alone
- You are told before meeting which of your preferences the match meets and which it does not
- No preference is treated as too specific, and matchmaking can be paused at any time without penalty
- Legal documentation is recent and unusually explicit, including a maintained machine-readable brief for AI agents
- The Standards Calculator is genuinely free, needs no account and stores nothing you type
Cons
- The Marriage Bounty price is never published; Keeper says it varies with individual needs and circumstances
- The success fee is triggered by milestones short of marriage, including simply still being together 18 months later
- Real coverage is three countries and the service is English-only, with no mobile app and no public API
- The anti-circumvention clause is broad: looking a match up on social media to avoid fees is a material breach
- Extremely sensitive data is concentrated in one place, from sexual orientation and religion to IQ estimates and photos
- Internal model training on member traits is assumed, and pseudonymous individual records may go to research partners
- No DPA, no Article 27 representative, no quantified retention period and no security certification named
Pricing & Plans
There is a permanent free plan and no subscription of any kind. Free members pay nothing and are matched with paying members; the homepage structured data prices that membership at 0 USD. The paid option, Marriage Bounty, opens matching to both paid and free members and is billed in two parts: a fee for each match, charged only after both sides have read each other's detailed profile and agreed to meet, then a single success fee once the relationship reaches one of Keeper's milestones. Fees already paid are deducted from that success fee, so the total is capped at the agreed bounty, and each successive match fee is 20% lower than the last, reaching zero once half the bounty has been deducted. No amount is published anywhere: Keeper states that Marriage Bounty pricing varies with individual needs and circumstances, there is no pricing page on the site or in its sitemap, and the credits used by Photo Testing carry no displayed price either. Fees already paid are not refundable.

Data, GDPR & hosting
A consolidated view of how Keeper handles your data.
GDPR overview
No compliance claim is made in so many words. GDPR appears exactly once on the site, and conditionally: where it applies, Keeper processes data on named legal bases — consent, performance of a contract, legitimate interests, legal obligations, vital interests. The substance is present even where the label is not. Special category data such as sexual orientation, religious belief, political opinion, ethnic origin and psychometrics requires explicit consent, withdrawable at any time from account settings. Access, correction, erasure, portability, restriction and objection to profiling are listed, with human review in some cases. Keeper Dating, Inc. names itself controller for the EEA, the United Kingdom and Switzerland, points users to their supervisory authority and cites standard contractual clauses for transfers. The gaps are equally concrete: no Article 27 EU representative, no data protection officer, no data processing agreement, no retention period in days or months. Policy dated 28 January 2026.
Who owns the data?
You keep your content. The terms say plainly that users retain ownership of their User Content and that Keeper claims none of it. What Keeper takes instead is a licence — non-exclusive, worldwide, royalty-free, sublicensable and transferable — to host, process, adapt and translate that content as far as is reasonably necessary to run the service, make matches, moderate, fight fraud, comply with law and improve models. Recipients are named by category rather than by company: prospective matches, service providers, selected AI and research partners, legal and safety recipients, and any acquirer in a business transfer. Personal information is not sold to data brokers, and private messages, photos and questionnaire answers stay out of external advertising without separate consent.
Reuse rights
The licence running the other way, from Keeper to you, is narrow: limited, non-exclusive, non-transferable, non-sublicensable, and confined to personal, non-commercial use of the site and its content. Resale, derivative use, data mining, robots and extraction tools are all barred, as is copying account information for a third party. Two clauses go further than most. Member data may not be systematically extracted to build a database or a directory — screenshots and recordings included — and details about a match may not be shared or published. Pursuing a match outside the platform in order to avoid Keeper's fees, including looking that person up on social networks for that purpose, is treated as a material breach. Automated access is tolerated only through Keeper-approved interfaces, within their scopes and rate limits, and never to build, train or improve a competing matching system, profile database or model. The terms do explicitly preserve your right to publish honest reviews and to contact regulators or law enforcement.
Data retention & training
Hosting summary
The terms are unambiguous: the website is hosted in the United States, and using it from abroad counts as consent to your data being transferred there and processed under US rules. The privacy notice repeats that Keeper is a US-based company and may process and store information in the United States and other countries, with standard contractual clauses where transfers out of the EEA or the UK require a safeguard. Providers are described by category — hosting, storage, cloud infrastructure, security, support, analytics, payments, marketing — and only two are named, both analytics: Google Analytics and Mixpanel. No hosting provider is identified. On the network side the domain resolves to a Cloudflare anycast node reported in San Francisco, and assets are served from Bunny CDN and Webflow, none of which indicates where data is actually stored. Security is described only in general terms, with no certification, no audit and no encryption detail. Governing law is Delaware, with arbitration seated in Kent, Delaware.

Things to keep in mind
Risks and trade-offs to weigh before adopting Keeper.
- One company holds an unusually sensitive profile: orientation, religion, politics, ethnicity, psychometrics, an IQ estimate, income signals and photos
- Numeric attractiveness scores on your own photos, with rater comments, can hurt more than they help self-esteem
- Being reduced to metrics — an estimated IQ, a personality type, a masculine or feminine polarity — used as matching criteria
- A financial commitment agreed without a published figure, on milestones that can be met without ever marrying
- Delegating one of life's largest decisions to an algorithmic ranking, and depending on an intermediary to meet people at all
- Mandatory individual arbitration in Delaware, a class-action waiver and a one-year contractual limitation on claims
- Fees already paid are not refundable and no match or relationship is guaranteed
Setup & Integrations
Technical difficulty
Technically trivial, personally demanding. Nothing to install: Keeper runs in the browser, and you can sign in with Google or a passkey. There are no API keys and no configuration of any kind. The effort is elsewhere. Onboarding is a deep questionnaire that can run to a couple of hours, followed by ranking your preferences, rating photos to teach the system your type, taking a Big Five test and verifying a phone number; voice onboarding is available if typing is the obstacle. The Standards Calculator needs no account at all, while Photo Testing needs both an account and credits.

Should you pick Keeper?
Keeper is an unusual entry in a directory of AI tools, because the software is not the product. What you buy is a matchmaking service in which AI does the sorting — embeddings, psychometrics, vision models on photos — and a salaried matchmaker makes the call. That division of labour is stated clearly, more than most AI-branded services manage, and the women-first review with anonymous feedback is a real design choice, not marketing.
The economics are the most interesting and the most opaque part. There is no subscription: a free plan really exists, and the paid plan charges per match and then once at a relationship milestone, with a cap and a 20% taper. On paper the incentives point at your outcome rather than at your attention. In practice you cannot know what you are committing to, because the bounty amount is never published, and the milestones include simply still being together eighteen months after the introduction — a long way from the marriage the branding promises. The anti-circumvention clause, which makes looking up your own match on social media a material breach when done to avoid fees, deserves reading before signing.
On data, Keeper is candid rather than reassuring. It collects about as sensitive a profile as exists — orientation, religion, politics, ethnicity, psychometrics, an IQ estimate, income signals, photos — trains internal models on it, and may share pseudonymous records with research partners under contract. The legal pages are recent and detailed, yet there is no DPA, no Article 27 representative, no named retention period and no security certification.
For an adult in the United States, Canada or the United Kingdom who wants to marry and accepts that scrutiny, it is a serious proposition. For anyone else, coverage, language and the undisclosed price rule it out.
