Ghost is a group messaging app that lets users post a variety of anonymous message types (Anon Crushes, hidden messages, Guess Who) inside small groups capped at 50 members. The app uses a client-side “Ghost Protocol” based on zero-knowledge proofs so the company does not learn group membership while still enforcing access. Ghost includes moderation guardrails: messages are auto-deleted after two reports and anonymous identities can be restricted across groups after repeat reports. The product also integrates ChatGPT (using the ChatGPT-3.5-turbo model) as a context-aware, multi-player assistant inside group chats under the feature name Ghost Question. The startup is shipping additional features (Anon Crushes expected imminently) and is prioritizing further ChatGPT access. The app launched from a waitlist of over 50,000, has about 30,000 installs post-launch, and is roughly No. 50 in the U.S. App Store social category.
