Description
Foreverse (also known as Xinmeng) is a mobile app that combines an AI fiction reader with tavern-style roleplay. It is built for long-form fiction rather than one-off prompts: readers can mark a passage, summon the AI in place, and continue the story where they point, with every direction becoming a new branch. Native-feeling page turns, worldbooks that follow the chapter, and in-book AI rewrites with undo keep the reading experience central.
Characters can live in four places, on the page, on a stage, at a table, or beside the reader as a companion, and support group chats, character cards, and worldbooks. A built-in AI agent with a set of skills can handle tasks across the reader's library, and companions support memory, calls, photos, and proactive messages. The app is compatible with SillyTavern-style character cards and presets for users migrating from that ecosystem.
Foreverse uses a bring-your-own-key model, connecting to more than 60 providers with keys kept on the device, and logs every API request with cost tracking and cache hits to save money. Billing supports both official credits and BYOK, with per-item ledgers and cost caps. A free browser demo, an official prompt template library, and detailed tutorials are available, and the Android app is on Google Play with iOS Early Access sign-up open.
