# Memory & Personalization

***

### How Memory Works

Nova uses a tiered memory system:

* **Recent context** — Nova remembers the last few messages in your conversation for natural follow-ups
* **Short-term memory** — Key topics from the last 48 hours are retained for continuity
* **Long-term memory** — Important facts and summaries are stored for up to 30 days

Blockchain-related conversations are prioritized for longer retention.

### Teaching Nova

You can ask Nova to remember specific facts about your server or group.

**Example prompts:**

> *"Remember that our project token is WELSH"*\
> \&#xNAN;*"Our treasury address is SP123..."*\
> \&#xNAN;*"We use ALEX DEX for all our swaps"*

Nova will store these facts and recall them in future conversations within the same context.

### Recalling Memories

**Example prompts:**

> *"What do you remember about our project?"*\
> \&#xNAN;*"What's our treasury address?"*

### User Preferences

Personalize how Nova interacts with you.

**Example prompts:**

> *"Set my timezone to UTC-5"*\
> \&#xNAN;*"I prefer detailed responses"*\
> \&#xNAN;*"My preferred language is Spanish"*

**Available preferences:**

* Timezone
* Response style (concise vs detailed)
* Language preference
* Personal notes

Your preferences follow you across all servers and groups where Nova is active.
