Inkstone
What Inkstone is
Inkstone is a free AI roleplay app for Android and Windows. It keeps chats, characters, lorebooks, settings, and other app data on the user’s device, while connecting to a model provider selected by the user to generate responses. Inkstone does not include a model, so AI generation requires the user’s own API key for a provider that supports the OpenAI API format. Supported options named by the maker include OpenRouter, DeepSeek, Z.AI, NanoGPT, OpenAI, and custom endpoints. The chosen provider handles generation under its own terms and privacy policy.
Users can create characters or import Character V2 cards from PNG images containing embedded JSON or from JSON files. Lorebooks supply world-building context and can be included in imported characters. Users can select community-made system prompt modes, provide their own prompts, and view which lorebook entries are active in the context. Appearance controls include ten handcrafted themes, plus options for colors, fonts, message bubbles, backgrounds, animations, and each chat’s atmosphere. The maker says Inkstone has no telemetry or usage tracking. Its documentation says API keys are kept in Android platform-native secure storage and sent only in requests to the configured provider.
Who it suits
Inkstone suits roleplay users who want to create or import characters, add lorebook context, and customize prompts and chat appearance. It is also suited to people who prefer app data to remain on their device and are prepared to configure and pay their chosen AI provider separately.
