Design Memory

Memory

Memory holds standing instructions that open every chat. A user writes each one once, such as a name to use or a writing rule, and never has to repeat it. Open Memory from Settings, under Chat, with Edit memory.

Top bar

Box	What it holds	Why
Back arrow	Returns to Settings	The phone's Back gesture does the same
Title	"Memory"	Names the screen

Two short notes follow the title. The first explains what memory does. The second says where the instructions go. With on-device chat they stay on the phone. When Chat uses OpenRouter, they go to OpenRouter with each message.

Instruction list

Box	What it holds	Why
Add instruction	An orange button that opens a dialog with one text field	The field suggests an example, so a first-time user sees what an instruction looks like
Instruction card	The instruction's text in full	Shows exactly what the model receives
Switch	On or off for each instruction	An instruction can rest without being deleted. A card that is off turns gray.
Edit	Opens the same dialog with the text filled in	Fixes a word without retyping the rest
Delete	Removes the instruction after a confirmation	The dialog repeats the text, so the user knows which one goes

An empty list shows two examples: "Call the user Mark." and "Do not use em dashes in your responses." Each instruction may hold up to 500 characters, and the list holds up to 50.

How memory reaches the model

The instructions that are on form the first part of the system prompt for every chat, on the phone or through OpenRouter. They come before the conversation, so they apply from the first message. The model reads them as the user's own standing request. A later message in the same chat can still override one.

Memory is stored as plain text in the app's private database. It is not a secret, so it is not encrypted the way keys are. Clear chat history leaves memory in place.

Chat history

The Memory and history card in Settings also holds two controls for chat history.

Box	What it holds	Why
Save chat history	A checkbox, on by default	When it is off, new chat messages live only in the app's memory and vanish when the app closes. The on-device engine also stops saving its conversation state. Images and videos are still saved, so their files can be kept.
Clear chat history	A red button with a confirmation	Deletes every chat message on the phone, saved or not. Images, videos, and memory stay.

Turning Save chat history back on hides the unsaved chat and shows the saved one again.
