Hazy vs OpenRP

Hazy is an interactive story platform where users speak and act as a character, and AI-driven characters respond in real time. Type what your character says or does to shape the story; the maker says the stories are not pre-written and users decide where they go. Its library includes romance, romantasy, dark fantasy, mystery, thriller, slice of life and other genres, with featured themes such as enemies to lovers, fated mates, forbidden first love, dark romance and slow burn. Hazy is free to start and provides credits at sign-up. Some interactions require Sparks, which are available through Apple in-app purchases; listed one-time purchases range from 1.99 USD for 120 Sparks to 49.99 USD for 3000 Sparks plus 1200 bonus Sparks. The maker says sessions save automatically for resuming on any device and stories and conversations remain private to the account. Hazy is listed for Android, iOS, macOS and web, though macOS is not verified in the app listing. The App Store rates it 18+ with content restrictions.

OpenRP is a web-based collaborative engine for building interactive fiction with worlds, characters, and dynamic narratives. Its visual world editor combines characters, backstory, and locations. Characters in one world can develop memories of each other, while edited content is embedded for retrieval in chat. The Behavior Engine connects language-model calls with chats and lore using conditions, loops, parallel branches, and HTTP requests. Pipelines can send generated messages to a Discord bot. Users can fork worlds, track edits, and propose changes to the original creator. Model controls expose context limits and estimated and actual usage costs. The Free plan has unlimited characters and messages with free AI models; Plus costs $10 a month and adds unlimited public and private worlds, monthly model credits, expanded personas and slots, feature requests, and priority support.
