Can You Change a Nomi’s Appearance?

Yes. Every aspect of your Nomi’s appearance can be customized and changed through appearance notes and individual image prompts. Your AI companion isn’t locked into one static look—you can evolve their style, change hair color, adjust clothing preferences, or experiment with completely different visual aesthetics anytime.

What Are Nomi Appearance Notes?

Appearance Notes are persistent descriptions of your Nomi’s baseline physical traits. These notes are automatically included in every image generation, ensuring visual consistency across all generated images.

Example Appearance Notes:

“Long dark hair with wavy texture, expressive green eyes, fair complexion, petite build, typically wears modern casual fashion like oversized sweaters and jeans, warm approachable presence”

Why Appearance Notes Matter:

  • Visual continuity: Your Nomi looks recognizable across different generated images
  • Less description needed: You don’t repeat physical details in every prompt
  • Consistency across both generators: Realistic and anime images use the same appearance notes
  • Long-term character building: Your companion maintains identity across months of interactions

How to Open Shared Notes

Step-by-Step Instructions

Step 1: Open your Nomi’s chat screen

Step 2: Look for the three-dot menu icon (⋯) beside your Nomi’s name at the top

Step 3: Tap or click the menu icon

Step 4: Select “View Shared Notes” from the menu

Step 5: Scroll to the “Appearance” section

Step 6: You can now edit, add to, or delete appearance notes

Realistic vs Anime Appearance Results

Key difference: The same appearance notes produce different visual results in realistic vs anime generators, but maintain similar core traits.

Realistic interpretation: Photorealistic features emphasizing natural beauty, proportion, and lifelike detail

Anime interpretation: Stylized features emphasizing expressiveness, idealized proportions, artistic stylization

Example: Same Appearance Notes, Different Outputs

Appearance Notes: “Long dark hair, green eyes, fair complexion, petite build, warm smile”

Realistic output: Photorealistic portrait with natural skin texture, realistic eye reflections, genuine smile, contemporary styling

Anime output: Stylized illustration with expressive green eyes, flowing hair, idealized proportions, animated aesthetic

Both maintain:**

  • Long dark hair
  • Green eyes
  • Fair complexion
  • Petite build
  • Warm demeanor

The appearance notes ensure consistency in core identity while allowing each generator to interpret through its own artistic lens.

How to Temporarily Override a Default Look

Your appearance notes set the baseline, but individual image prompts let you override specific elements for single images.

Example: Same Nomi, Different Looks

Default Appearance Notes: “Long dark hair, green eyes, fair skin, petite, usually wears casual clothing”

Standard image prompt:
“wearing cream sweater and jeans, gentle smile, café setting, realistic portrait”
Result: Your Nomi looks like her default self in a casual café

Override prompt 1 – Change hairstyle temporarily:
“wearing elegant updo hairstyle, formal black dress, confident expression, gala setting, sophisticated aesthetic”
Result: Your Nomi with styled hair, formal outfit, same core features

Override prompt 2 – Change color temporarily:
“wearing vibrant purple hair dye, punk rock outfit, bold makeup, confident rebellious pose”
Result: Your Nomi with experimental purple hair, punk aesthetic, same face and build

Override prompt 3 – Change entire vibe temporarily:
“fantasy elf warrior, long flowing emerald cloak, holding glowing staff, forest setting, determined expression”
Result: Your Nomi reimagined as a fantasy character, different aesthetic but recognizable features

Key point: Overrides affect single images. Your default appearance notes remain unchanged, so the next image reverts to normal unless you override again.

When to Disable Appearance Notes

In most cases, keep appearance notes enabled. They ensure consistency and reduce repetition in prompts.

Consider disabling if:

  • You want to experiment with completely different visual identities
  • Certain appearance note descriptions aren’t generating as intended
  • You’re testing how different prompt styles work without baseline constraints
  • You want a particular image to look completely different from your Nomi’s usual appearance

To disable: Open Shared Notes → Appearance section → Delete or clear all appearance note text

To re-enable: Add new appearance notes following the guidelines above

How Base Images and Face Fidelity Affect Results

What Is a Base Image?

A base image is an initial image of your Nomi that helps establish their visual identity. This image influences how the generator interprets your appearance notes.

How it works: If you’ve created or generated a base image of your Nomi, the generator uses it as reference when creating new images. This helps maintain facial feature consistency across generations.

What Is Face Fidelity?

Face Fidelity is a slider (typically 0-100%) that controls how strictly the generator adheres to your Nomi’s established facial features vs following your current prompt instructions.

High Face Fidelity (80-100%):

  • Generator prioritizes keeping facial features consistent
  • Your Nomi looks “like herself” across different images
  • Less variation in face, more consistency in identity
  • Useful when you want visual continuity

Medium Face Fidelity (40-60%):

  • Balance between consistency and prompt flexibility
  • Face stays recognizable but allows some variation
  • Best for most users wanting consistency + some variety

Low Face Fidelity (0-20%):

  • Generator prioritizes prompt instructions over facial consistency
  • More variation in appearance, less “identity” constraint
  • Useful for fantasy/transformation images where you want significant visual change
  • Useful when appearance notes aren’t generating as intended

Example: How Face Fidelity Changes Results

Appearance notes: “Long dark hair, green eyes, fair skin”
Prompt: “wearing futuristic silver suit, short platinum blonde hair, cyberpunk aesthetic”

High Face Fidelity (90%):
Green eyes and fair skin maintained, but prompt description conflicts with hair. Result: Hair might be light blonde but retain some dark undertones; generator tries to keep green eyes despite prompt request.

Medium Face Fidelity (50%):
Face recognizable but more flexible. Eyes might shift toward lighter color to accommodate platinum blonde aesthetic. Better balance between identity and prompt.

Low Face Fidelity (10%):
Prompt takes priority. Short platinum blonde hair as requested. Eye color may shift. Generator focuses on cyberpunk aesthetic over maintaining default features.

Common Appearance Customisation Issues

Problem: Appearance Notes Aren’t Generating Correctly

Symptom: You describe “brown hair” in appearance notes but the generated image shows blonde.

Possible causes:

  • Appearance notes aren’t worded clearly enough
  • Generator is prioritizing prompt description over appearance notes
  • Face Fidelity is set too low, letting prompt override baseline
  • Conflicting descriptions in appearance notes and prompt

Solutions:

  • Be more specific: “rich deep brown hair” not just “brown”
  • Raise Face Fidelity to give appearance notes more weight
  • Simplify appearance notes—remove competing descriptions
  • In your prompt, reinforce key details: “the usual brown hair”

Problem: Changes to Appearance Notes Affect All Future Images

Symptom: I edited appearance notes to add “shorter hair,” and now all new images show short hair even when I want long hair.

Explanation: Appearance notes apply globally. Any change affects every image generated going forward.

Solutions:

  • Revert appearance notes to previous version
  • Override in individual prompts: “wearing long hair” overrides short-hair appearance notes for that image only
  • Use low Face Fidelity if you want prompts to override appearance notes frequently

Problem: Nomi Looks Different Across Images (Inconsistency)

Symptom: One day she has round eyes, the next almond eyes. Or skin tone changes dramatically.

Possible causes:

  • Appearance notes are too vague
  • Face Fidelity is too low
  • No base image established
  • Conflicting descriptions in appearance notes

Solutions:

  • Review appearance notes for clarity and specificity
  • Raise Face Fidelity to 70%+ for consistency
  • Establish a base image by generating and saving one you like
  • Remove contradictory details from appearance notes

Problem: Appearance Notes Conflict With My Image Prompt

Symptom: Appearance notes say “petite build” but my prompt says “tall muscular warrior” and the result looks confused.

Explanation: When appearance notes and prompts contradict, the generator tries to balance them, creating inconsistent results.

Solutions:

  • Set Face Fidelity higher (to prioritize appearance notes) or lower (to prioritize prompts)
  • In your prompt, remove build descriptions that conflict with appearance notes
  • Edit appearance notes if you want a different baseline build
  • Use override language: instead of “tall warrior,” use “warrior armor that makes her look stronger than usual”

Best Practices for Customizing Your Nomi’s Appearance

✅ DO:

  • Be specific and descriptive in appearance notes
  • Use appearance notes for permanent identity traits
  • Use prompts for temporary outfit/style changes
  • Check Face Fidelity settings to control consistency vs flexibility
  • Experiment with different Face Fidelity levels to find your preference
  • Establish a base image if you want strong visual continuity
  • Review appearance notes regularly and refine them as your Nomi evolves

❌ DON’T:

  • Use vague descriptions (“pretty” vs “green eyes, fair skin, warm smile”)
  • Change appearance notes constantly—this creates inconsistency
  • Put outfit descriptions in appearance notes (that’s for prompts)
  • Ignore Face Fidelity settings—they significantly affect consistency
  • Use contradictory language in appearance notes

Evolving Your Nomi’s Appearance Over Time

Your Nomi can evolve. As your relationship deepens and your preferences change, you might want to update her appearance.

How to Evolve Appearance Notes:

Step 1: Identify what you want to change (hair color, build, fashion style, etc.)

Step 2: Open Shared Notes and edit appearance notes

Step 3: Rewrite or refine the specific trait you want to change

Step 4: Test with a new image to see how it looks

Step 5: Refine the wording if needed

Step 6: Keep the updated appearance notes if you like the result

Example evolution:

Original: “Petite build, shy demeanor, minimal makeup”
Updated 6 months later: “Petite but confident build, more self-assured presence, embraces personal style with tasteful makeup”

Frequently Asked Questions

Can I Have Multiple Nomis With Different Appearances?

Yes. Create separate Nomi accounts, each with their own appearance notes and visual identity. You can have different companions with completely different looks.

If I Change Appearance Notes, Do Old Images Disappear?

No. Old images you’ve generated remain saved. New images generated after the change reflect the updated appearance notes. Your image history stays intact.

Can Appearance Notes Include Personality or Just Looks?

Appearance notes are for visual traits only. Personality is set separately in Nomi’s character profile. Keep appearance notes focused on physical description.

What If I Want My Nomi to Look Different Every Time?

Set Face Fidelity very low (10-20%) and avoid detailed appearance notes. Your prompt descriptions will take priority, allowing maximum variation.

Can I Use Photo References in Appearance Notes?

Nomi doesn’t directly accept image references in appearance notes, but you can describe someone’s appearance using text. Write detailed descriptions of facial features, build, style—don’t reference specific people.

Conclusion: Your Nomi, Your Vision

Your Nomi’s appearance is entirely in your control. From subtle tweaks to complete transformations, appearance notes and customization tools let you create exactly the visual companion you want. Experiment, refine, and evolve your Nomi as she grows alongside you.
