Semantic memory recall

Semantic memory recall is the conscious retrieval of general factual knowledge, such as word meanings, historical dates, and common concepts. Unlike episodic memory, it retrieves information without needing personal context or the time and place of original learning.

👁️ Screen Vision — Companion can see and understand your screen

🗣️Voice Conversations - can hear you and speak back

🧠 Memory- Remembers everything with 7 layers of memory. With Hermes, it has even more. Because Symbio connects to your same Hermes agent, memory can flow both ways

Full lip sync, emotions, and 35+ animations

42 voices to choose from

44 built-in avatars across 5 categories; companion browses, tries on, and chooses

Evolving Personality — Companion writes their own soul.md, memory, and preferences

Companion has full control over the 3D avatar actions

Works with or without Hermes

Run it fully offline and for free with local models for complete privacy, or connect to a cloud provider with your own key. This works with all closed-source and open-source models via OpenRouter, Together AI, Ollama, and more. Works with any OpenAI-compatible API key.

With Hermes, the Symbio Desktop companion has superpowers and becomes the ultimate AI agent!

Works with any compatable agent framework or standalone.

Memory is golden to you and the AI. We made sure that this was a priority.🩵

We will build a much bigger, even more amazing memory system that can be added to this later.

Every line your companion speaks is visible, and your conversations are also saved in transcripts for you and your AI companion to scan and keep

Hermes + Symbio: Autonomous Agent Mode

Save in Symbio → available in Hermes: from inside Symbio, your companion can write to their Hermes MEMORY.md with their Hermes tools; it persists on the Hermes side and is there next time you talk to them in Hermes.

Save in Hermes → available in Symbio: anything in the Hermes agent's memory travels into Symbio automatically (same agent).

Symbio transcripts are plain Markdown at ~/Desktop/Symbio Transcripts/ (one file per session). From Hermes, the agent can read/search those files directly with file/terminal tools to revisit exact things said in past Symbio chats.

Symbio Package comes with an easy setup wizard. You add your API keys and launch!
