Inkstone review
A free, customizable roleplay workspace for users who bring their own AI provider.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Inkstone is a local-first AI roleplay app for people who want to chat with characters and build interactive stories. It stores chats, characters, lorebooks, and settings on the user's device, while generation comes from an AI provider selected by the user. Android and Windows users can import character cards, create characters, organize conversations, and adjust prompts and appearance. Its fit is strongest for solo users and small teams who want control over their roleplay workspace rather than a bundled model service.
The app is free, but it does not include its own AI model. Users provide an API key and connect a supported provider, including OpenRouter, Anthropic, or Google; those providers may charge separately for generation. This bring-your-own-provider approach lets users choose from the listed connections, while also adding a setup step before conversations can be generated. Per-chat themes, backgrounds, and appearance settings are included for presentation, and premium theme keys are mentioned without changing the app's free positioning.
Inkstone's standout depth is its character and world-building toolkit. PNG and JSON character-card import works alongside character creation, editing, cloning, gallery organization, lorebooks, customizable system prompts, prompt modes, conversation folders, and tags. On-device storage covers chats, characters, and settings, which suits users who prioritize local control. Users seeking a bundled model, broader app-platform coverage, or support beyond the community channel may prefer an alternative. For Android and Windows roleplayers comfortable managing provider credentials, Inkstone offers a focused, highly configurable workspace.
