Assistant

How the assistant behaves and how the app looks. Keys and models aren't set up here; they are in the Models subsection.

Personal instructions

Custom instructions: what the assistant should know about how to answer you. You can also change them from a chat: say, for example, "answer me more briefly", and the assistant suggests new text with a card; you apply it, and you can undo it. For example: "answer briefly, explain terms in plain words, answer in English". The instructions are stored encrypted and apply to all new answers. They don't override MindDuck's privacy and safety rules.

Click Save preferences to apply the changes.

• Let the assistant suggest facts: allow the assistant to suggest facts to remember. Suggestions aren't used until you confirm them. See Facts.
• Search memory for every text message: an experimental mode: search memory before every message, not only when the question hints at it.
• Smart memory selection: before answering, the Jev model on OpenRouter looks through up to 300 fragments found in memory and keeps up to five that really help answer. The fragments go to OpenRouter with your key; an answer costs a fraction of a cent. If the selection doesn't fit into a second or fails, the regular one is used. You need an OpenRouter key in Models. Modes: Automatic (default) for chats through OpenRouter; Always for chats through other providers too; Off. If a chat goes through another provider and you have an OpenRouter key, MindDuck asks once in the chat whether to turn on the selection. Below the mode are Connection (which OpenRouter connection to use; Automatic takes the chat's connection or the first one with a key) and Relevance model (empty means the default model, currently typesafe/jev-1.13). The Test button checks the connection and the model on two short made-up fragments. You can ask the assistant to turn it on or off, and it will suggest the change with a card.

Size and spacing

Interface and text size, independently of each other. Applies only to this device: you can choose different sizes on your phone and your computer.

• Interface scale: the whole app: text, spacing, buttons;
• Chat text: only the text of messages, on top of the interface scale;
• Chat line spacing: the distance between lines in messages.
• Document font: the font of documents for reading and editing: Sans (Inter), Serif (Literata, a book font for long reading on screen), Mono or System (the device's font);
• Document text and Document line spacing: text size and line spacing in documents;
• Chat width and Document width: the width of the text column on large screens. You can also change it with the mouse: hover over the edge of the text in a chat or a document, a thin line appears, drag it. A double click on the edge returns the default width. While dragging you see roughly how many characters fit in a line; 65 to 80 is comfortable to read.

Web page reader

How the assistant opens pages from the internet: Automatic: this device first, then Jina Reader, Local only or Always use Jina Reader, and whether pages built by scripts open in the background browser on the device. The same place has the Local servers the assistant may open list: local addresses such as http://localhost:3000 the assistant may open. The list is stored only on this device. See Web search and reading pages.

Model work display

What to show while the model answers: Detailed, Compact or Developer. It changes only the display. See How to read the answer.

Developer mode

Shows request traces, diagnostics and manual control of summaries and topic analysis. Not needed for regular work.

Under each assistant answer, the Developer trace row shows where the time before the first word went: Request prepared in … is building the request on this device (context, memory search), API answered after … is waiting for the provider's response. The same values are in the Export debug trace file, in the timing field (preparationMs, waitForFirstOutputMs). Answers created by earlier versions don't have this data.
