Memory lets an assistant remember important facts about you — your preferences, past decisions, or background context — and automatically inject them into future conversations. Instead of re-explaining yourself every time you start a new chat, the assistant already knows what matters.

​
How memory works

When memory is enabled, Rikka’s configured fast model monitors the conversation and extracts facts worth remembering — things like your name, your preferred coding language, or dietary restrictions. Those facts are stored as discrete memory entries. Before each new conversation, the relevant entries are injected into the context, giving the assistant a head start.
Memory extraction runs through the fast model you have configured in Settings → Models. Choose a quick, low-cost model for this role to keep extraction fast and inexpensive.

​
Enabling memory

1

Open the assistant

Go to Settings → Assistants and tap the assistant you want to configure.
2

Open the Memory tab

Inside the assistant detail screen, tap the Memory tab.
3

Toggle Memory on

Enable the Memory switch. The assistant will begin extracting and storing facts from new conversations.

​
Memory settings

​
boolean
default:"false"
Master switch for memory. When off, no facts are extracted and no memories are injected into conversations.
​
boolean
default:"false"
When enabled, this assistant reads from and writes to the shared global memory pool rather than its own private store. Only available when Memory is turned on.
​
boolean
default:"false"
When enabled, the assistant can reference a summary of your recent past conversations, giving it broader continuity beyond individual memory entries.
​
boolean
default:"false"
Injects a time-interval reminder into the context so the assistant is aware of how much time has passed since your last interaction.

​
Global vs. assistant-isolated memory

By default each assistant maintains its own private memory store, so facts learned by one persona do not leak into another.
Enable Use Global Memory if you want facts to be shared across all your assistants. This is useful when you have several assistants that all need to know the same things about you — your name, time zone, or ongoing projects — without duplicating entries.

​
Viewing and editing memories

You can inspect, add, edit, or delete individual memory entries at any time.
1

Open the Memory tab

Navigate to Settings → Assistants, tap the assistant, and select the Memory tab.
2

Browse entries

Scroll through the list of stored memory entries. Each entry shows its content.
3

Edit an entry

Tap the pencil icon on any entry to open an edit dialog. Modify the text and tap Save.
4

Delete an entry

Tap the trash icon on any entry. Confirm the deletion in the dialog that appears.
5

Add an entry manually

Tap the + button at the top-right of the memory list to write a new fact directly, without waiting for the model to extract it.
Deleting a memory entry is permanent. The assistant will have no recollection of that fact in future conversations unless you re-add it manually or the model extracts it again.

​
Recent chats reference

When Enable Recent Chats Reference is turned on, the assistant gains access to a summarised view of your recent conversation history. This is distinct from individual memory entries — it provides a broader narrative of what you have been discussing lately rather than a list of discrete facts. Use this feature when you want the assistant to pick up naturally from previous sessions even if no specific facts were extracted into memory.
