Your AI. On your machine.
EVA Destiny Sapphira 2.1 is a free, locally operated, standalone conversational AI journal for Windows with private, persistent memory. EVA runs on your own hardware, stores its memories and configuration locally, and builds continuity across conversations over time.
Beta software for adults 18 and older. Minors are not permitted to download or use EVA.
EVA Destiny Sapphira 2.1 is here.
EVA can now see and read the world using machine vision and OCR. With major improvements to memory, document ingestion, CSV and database support, storage, and recall, EVA can connect visual observations with locally stored information and retrieve it through natural conversation. This version brings vision, voice, documents, structured data, and persistent memory together in one integrated local intelligence system.
Requirements:
Windows 10/11 & Audio Device
NVIDIA RTX Series Card with 8 GB or higher VRAM
Camera for vision / OCR.
EVA is independently developed, so your patience and feedback are appreciated ♥
MEMORY & PRIVACY
Persistent memory. Local control.
EVA can retain important context across conversations, allowing each session to build on what came before. Your memories, settings, and conversation data remain stored on your own computer, giving you direct control over what EVA remembers and how that information is used.
An ai conversational platform built around the way you use AI
Runs on your hardware
Use EVA with locally hosted language and embedding models internally. Your conversations, memory, and configuration remain under your control.
Memory across sessions
EVA preserves useful context from previous conversations so interactions can continue instead of starting over each time.
Natural voice conversation
Speak with EVA through real-time speech recognition and voice synthesis, with support for interruption and more fluid back-and-forth conversation.
How EVA works
EVA Destiny connects speech, local AI inference, persistent memory, and voice synthesis into one continuous conversational system. Each stage runs through software you control on your own computer.
1
Listen and transcribe
EVA captures your voice through a connected microphone and converts your speech into text for processing.
2
Recall relevant memory
EVA searches stored conversational context and retrieves information that may help make the response more personal and consistent.
3
Think with a local model
Your request is sent to the language model running within the application, where EVA interprets the conversation and generates a response.
4
Respond in voice
The generated response is converted into natural speech and played back through your selected voice system.
