Creating Prompts

You can create your own prompts to save instructions you use frequently. Prompts can be kept private or published to the library for others to discover and use.

Ways to create a prompt

From the library

Go to /prompts and click New Prompt in the top right corner. This opens the prompt editor with a blank form.

From a message in chat

If you’ve written a message that works really well as a reusable template, you can save it as a prompt directly. Hover over the message and click the Save as prompt option (the bookmark icon in the message actions menu). The message text will be pre-filled in the prompt editor so you can review and adjust it before saving.

Filling in the prompt details

Name and description

Give your prompt a clear, memorable name. The description appears on the prompt card in the library, so write a sentence or two explaining what the prompt does and when to use it.

Prompt type

Choose one of two types:

• System prompt: The content will be used as a persona or behavioral instruction for the AI. It’s applied to a conversation as a whole and shapes how the AI responds to every message.
• User prompt: The content is a message template inserted into the chat input. It’s useful for tasks you do repeatedly, like formatting requests or analysis patterns.

Content

Write the actual prompt text. For system prompts, this is where you define the AI’s role, tone, constraints, and any specific behaviors. For user prompts, write the template message you want to reuse. You can leave placeholder text where you’ll fill in specific details before sending.

Tags

Add tags to make the prompt easier to find in the library. Use tags that describe the topic, style, or use case (for example: writing, coding, research, formal, concise). You can add multiple tags.

Optional presets

When creating a system prompt, you can attach optional defaults that will be applied automatically whenever the prompt is activated on a conversation:

• Model: Pre-select a specific AI model that works best with this prompt. For example, a reasoning-heavy system prompt might work best paired with a reasoning-capable model.
• Mode: Pre-select a chat mode (Chat, Search, Reasoning, etc.) that matches the intent of the prompt.

These presets are suggestions. You can always override them after activating the prompt on a conversation.

Publishing

By default, new prompts are private and only visible to you. To share a prompt with the Magus community, toggle the Public option before saving. Public prompts appear in the shared section of the library where other users can browse and activate them.

You can change the visibility of a prompt at any time from the prompt’s edit page.
