ENGRAI: Your Private AI Tool. Simplified for Your Convenience. A native iOS and macOS client for AI-driven character conversations, called ENGRAIs. Your ENGRAIs, personas, and conversations live exclusively on your device. Messages go directly from your device to the endpoint you chose. ENGRAI simplifies the complexity of local large language models and setup by providing an interface that handles the technical work under the hood, so you can plug them in and use them with ease. Why Choose ENGRAI? - Fast & Fluid: Built natively for iOS and macOS, ENGRAI is designed for speed and battery efficiency. No web wrappersβ€”just a smooth, responsive experience. - Consistent Identities: Define ENGRAIs across their identity, appearance, and detailed behavioral profiles. Characters & sessions remain consistent even in the longest storylines, without drifting after 20 messages. - Immersive World Building: Author detailed sandboxes for your stories. From overarching lore to specific settings, ensure every conversation is grounded in a consistent world. - Dynamic Relationships: Characters don't just chat with you; they chat with the world you build and other characters. Yes, group scenes let you put multiple ENGRAIs you create into a shared world you author. - Smart Long-Term Memory: Our automatic summarization ensures that ENGRAIs remember the important details - events, plot twists, and anything relevant you want an ENGRAI to remember after 20 messages. - Endless Possibilities: Customize everything. From app themes and fonts to advanced LLM settings, you control how your AI behaves, works, and engages in chats with your worlds. - Privacy First: No accounts, no analytics, and no developer server. Your API keys are stored securely in your device's keychain. With local models, your data never leaves your network. - Community Ready: Power users can easily import JSON-compatible character cards they use on their favorite LLM chat apps. Use them to keep your conversations, characters, personas, prompts, or lorebooks consistent without starting over. - Smarter Recall: Characters, assistants, or the worlds themselves? They all use state-of-the-art retrieval-augmented generation (RAG) to reference your lorebooks & artifacts by meaning. All thanks to your own device's power! - Assistant Chat: ENGRAI lets you use your own keys to enjoy a polished assistant chat with the same recall and session memory. You can upload files, use your own web tools, and ask your assistant to handle a wide range of tasks. Summarize a document? Draft a written piece of text? Search for sources? ENGRAI Assistant chat can handle all of that! - On Device Too: Don’t have your own key? ENGRAI lets you download and install models that run on devices of all sizes. All run on the device, using its powerful processing, fully private, fully local. ENGRAI is free. No subscriptions, no paid tiers, and no ads. ENGRAI is a project built by an indie developer for users who value privacy and freedom. REQUIREMENTS ENGRAI does not include an AI model or provide one. You need your own API key from a third-party AI provider or a locally hosted model. You are responsible for any usage costs that the provider charges you, and your use of their service is governed by their terms. ENGRAI is intended for adults aged 18 and over. You are responsible for the content you generate and for complying with the policies of the provider you connect to.
