Company profile
researched Sep 2026Diem is a social search engine and community platform positioned at the intersection of a search engine and a social network, designed first for girls, women and LGBTQIA+ users. Users can query Diem AI, a model that combines a large language model with the company's own data model built from knowledge shared by community members. A query returns an AI-generated summary answer supplemented by community sources (previous related conversations inside Diem), community spaces, web pages, Reddit threads and TikTok videos. Users can alternatively post their search to the community feed to solicit real-time responses from other members.
The platform's stated purpose is to close what it calls the "gender information gap" by turning candid, typically private conversations — on friendships, birth control, harassment, chronic pain, career decisions, sexuality, money, reproductive health, books and recipes — into public, searchable resources. Product features include anonymous or pseudonymous posting, Community Spaces (micro-communities such as "Am I wrong?", "Big Sis Advice" and "Is this Normal…?") that surface in related searches, long-form post creation, upvoting and bookmarking, and "Lenses" that let users pose questions to experts and creators. Moderation is distributed, with reported content reviewed by the company; direct messaging has deliberately not been shipped, which the company attributes to safety and moderation considerations and to a preference for keeping shared knowledge publicly accessible.
The company publishes internal messaging guidelines covering people-first language and gender-neutral phrasing, and runs "Diem Days," in-app activations tied to dates such as June 10 (marking the 1993 requirement for women's inclusion in U.S. clinical research) and National Lipstick Day on July 29.
Business model
Diem operates a consumer mobile and web platform offered free to download on iOS and Android, combining AI search with user-generated community content. Value accrues from the knowledge contributed by its members: community posts and responses feed the data model behind Diem AI, so contributions improve search quality for all users. The company also runs an in-app rewards mechanic in which "Gems" earned through usage can be exchanged in a "Little Treat Store" for products, discounts and pro features, and it distributes a newsletter.
Traction
The iOS app has 116 ratings averaging 3.9 out of 5, and the Android app lists more than 10,000 downloads as of its July 2025 update. The company states its platform holds thousands of conversations from users in more than 100 countries, with several Community Spaces live including "Am I wrong?", "Big Sis Advice" and "Is this Normal…?"
Latest developments
As of a July 2025 Android release, Diem introduced focused modes that let users choose between Diem AI mode and Community mode with the ability to switch at any time, alongside a new navigation menu and broad bug fixes and UI improvements. The company has also rolled out Diem AI Lenses for questions directed at experts and creators, a Gems rewards currency redeemable in a "Little Treat Store" on iOS and Android, and promotes a companion astrology iOS app, TWIN FLAME. App store reviews from March 2025 report bugs including lost post drafts and notification links that fail to open the referenced post, which the company acknowledged in a developer response.

Market position
Diem positions itself as an alternative "front door" to the internet for a specific audience, drawing comparisons from its own materials and users to Reddit, Google and ChatGPT while emphasizing a community-sourced, women- and LGBTQIA+-first orientation. The company characterizes itself as early-stage in building out its search engine and Community Spaces. Its Android listing shows more than 10,000 downloads and its iOS listing shows 116 ratings averaging 3.9 out of 5.
Diem differentiates on audience and data source rather than on general-purpose search: its results are drawn from a community of girls, women and LGBTQIA+ contributors and are framed, in the company's words, through a feminine lens, with the stated aim of being less biased than other models. Features not typical of mainstream search — anonymous or pseudonymous posting, Community Spaces, creator/expert "Lenses," and the option to convert a search into a community question — combine search results with peer validation. The company states there are no popularity contests on the platform and that it does not prioritize highly curated content, and it emphasizes privacy, committing not to share users' personal data.
Technology
The core product is Diem AI, a conversational search model that pairs a large language model with the company's proprietary data model built from member-contributed knowledge. Queries return a short AI-generated summary assembled from Diem's own content and the wider web, then surface supporting community sources, Community Spaces, web pages, Reddit threads and TikTok videos. The system is designed to improve as members contribute more stories and questions. The company describes the search engine as designed to be less biased than other models. Applications are available on iOS (42.8 MB, iPhone and iPad) and Android.
Go-to-market
Distribution is direct-to-consumer through the Apple App Store and Google Play plus a web sign-up, supported by an email newsletter, in-app activations ("Diem Days") tied to calendar moments, creator and expert "Lenses," and a Gems-based rewards store. The company publicly engages with app store reviewers, responding to feedback about threading, UI and the absence of direct messaging.
Consumers, designed first for girls, women and LGBTQIA+ people. Usage clusters around personal health, career, sex, money, sexuality, friendship, confidence and dating questions, as well as parenting, relationships, reproductive health, pop culture and books.
Geography
Diem Enterprises Inc. lists an address on Ridge Street in New York, NY, United States. The app is distributed through the U.S. App Store and Google Play in English, and the company states its community spans users in more than 100 countries.
History
Diem operates as Diem Enterprises Inc. (also listed as developer "Diem Tech" on Google Play), with an address in New York, NY. The company describes itself as still early in its journey to build a social search engine. Its iOS app is listed in the Lifestyle category with an 18+ age rating, while the Android listing carries a Teen rating and surpassed 10,000 downloads; an app update shipped in July 2025 introduced separate Diem AI and Community modes and navigation changes. The website also promotes a related astrology iOS app called TWIN FLAME.
Risks & controversies
User reviews on the iOS App Store cite product stability and usability problems, including posts being erased when the screen is tapped or the phone sleeps and notifications that do not link to the referenced post; the company responded acknowledging a confusing threading UI and ongoing fixes. The platform does not offer direct messaging, which the company attributes to moderation and safety considerations. The Google Play data-safety disclosure states the app may share personal information with third parties and may collect location, personal information and five other data types, with data encrypted in transit and deletion available on request. The company also describes itself as early in its build-out and cautions users that the product is still developing.
