About this mod
Bring every NPC to life with AI. Mantella allows you to have natural, real-time conversations with NPCs by leveraging speech-to-text, LLMs, and text-to-speech technologies. NPCs have memories of your previous conversations, are aware of in-game events, have vision, and can even perform actions.

- "I honestly never thought something like this could exist"
- "This integration made Skyrim into my dream game"
- "Absolutely mind-blowing mod"
- "This truly adds an amazing level of depth to Skyrim"
- "I asked her what she wanted to be if she couldn't be a blacksmith. She said adventurer. I told her I was one, and that it wasn't all it's cracked up to be, and she asked me why. When she asked me why, all of a sudden I was just having a conversation. It felt a lot more real."
- "It's so epic to finally be able to delve into these characters in a completely dynamic way. How many times have you role played this sort of interaction in your head? You can build this relationship with the NPCs that is completely unique. The conversation evolves and is shaped by you. The questions you ask, the way you behave and the way you communicate creates a completely unique response from the AI. They truly have been brought to life."
FAQ
Does Mantella only work in VR?
Mantella is also available for non-VR PC versions of Skyrim (SE / AE).
How much does it cost to run Mantella?
Mantella can be run completely for free. If your hardware is able to support running local language models you can run completely offline for free. If you would prefer to outsource this processing externally, you can also connect to many services, with the default being set to OpenRouter:
OpenRouter: This is Mantella's "default" option when setting up, as OpenRouter offers free models for up to 100 requests a day. The OpenRouter API is billed by using pre-paid credits for the use of paid models. See here for more details: https://openrouter.ai/docs#models
Are there high PC hardware requirements to run this?
