Amber Copilot is your AI writing assistant. Choose between Chat Mode for brainstorming and feedback, or Editor Mode for precise text revisions. You maintain complete control over all suggestions.
You are the author. AI is your assistant. Amber Copilot never writes for you—it helps you refine what YOU’VE written. Your words, your voice, your intellectual property. Always.

​
Two Modes

Chat Mode - Ask questions, brainstorm ideas, and discuss your writing
  • Quick Chat (⌘L) for instant feedback on selected text
  • Full Conversation mode for comprehensive project discussions
  • Control what context the AI sees (entire workspace, current section, notes only, or selected text)
  • Preserve conversation history across sessions
Editor Mode - Request specific text edits with a beautiful diff view
  • Select text and describe what you want to change
  • See exactly what will change before accepting
  • Accept, reject, or ask for alternatives for each change
  • Fully reversible through undo or Git history

​
Using Sources

Store detailed reference materials that inform Copilot’s understanding:
  • Character backstories and voice notes
  • World-building documents (magic systems, geography, politics)
  • Research material and plot outlines
  • Inspirational passages and style examples
When you ask Copilot a question, it intelligently finds the right sources from your project. This means faster responses and smarter suggestions that truly understand your story, characters, and world.
Sources are stored as markdown files in your Sources/ folder, so you can create them in any text editor and they’ll appear in Amber automatically.

​
Steering Your Copilot with amber.md

Create an amber.md file in your workspace root to guide how Copilot assists you. Instead of configuring through menus, write markdown instructions about:
  • Your writing style and tone
  • Character voices and consistency rules
  • Plot constraints and world-building rules
  • How you want AI to help
Example structure: 
# My Novel - Amber Steering

## About This Project
Dark fantasy set in a medieval world. Mysterious, atmospheric tone.

## Writing Style
- Prefer showing over telling
- Sophisticated but accessible vocabulary
- Third person limited POV

## Main Characters
- Kira: Disillusioned mage, sarcastic and intellectual
- Dante: Street orphan, street-smart but emotionally vulnerable

## Plot Constraints
- No romantic subplots before Chapter 10
- Magic must have a cost
Changes to amber.md take effect immediately—no restart needed.

Best Practices

​
For Chat Mode

  • Use “Entire Workspace” scope when brainstorming plot
  • Use “Current Section” scope for feedback on one scene
  • Be specific in your questions
  • Reference your Sources: “Based on Elena’s backstory, how would she…”

​
For Editor Mode

  • Be specific about what you want: “Make this more vivid” vs “Fix this”
  • Reference your steering file: “Make this sound like Elena (see amber.md)”
  • Start with smaller edits—iterate toward what you want
  • Keep major plot and character decisions in your hands
