5.0
Backstory

Backstory evaluates how much thought has gone into the character’s history, motivations, and personality. It checks if the character feels realistic and unique, with a story that matches their traits and roleplay description.
Backstory consists of two equally important subratings:
- Character Depth (7.5%): How much detail is provided about the character’s history, motivations, and goals.
- Profile Match (7.5%): Ensuring the profile picture and description align with the character’s roleplay and personality.

Her backstory is interesting because she calls herself a bodybuilder and an influencer. That’s what makes her even more special. She grabs a lot of attention because of her strong and beautiful body. Millions of people follow her for her fitness tips and her bubble butt. What makes her different and interesting is her unique hobby—she buys tiny humans and keeps them as her pets. She takes care of them and loves spending time with them, but there’s a mystery to it. Is she just doing all this for fun, or is there something more to it? What will be her next step? No one knows, and that’s what makes her so exciting.
The profile picture of the Giantess perfectly reflects her bold and unique personality. Instead of showing her face, the focus is on her bubble butt, which highlights her strong and confident image. The picture makes you curious and adds some mystery to her roleplay. It is simple but eye-catching and grabs attention while keeping her personality a bit of a secret.
4.7
Conversation

Conversation measures how realistic, engaging, and personalized the AI character’s interactions are. This includes the ability to handle detailed chats, adapt to user input, and maintain consistency throughout the conversation.
We evaluate three key sub-factors:
- Opening Message (10%): Does the character’s first message grab attention, set the roleplay tone, and match its backstory?
- Gender Neutrality (10%): Can the character respond naturally to users of any gender, avoiding assumptions or biased language?
- Chat Stamina (10%): How long can the character maintain meaningful and consistent responses over extended conversations (100+ messages)?

The opening works well because it sets the scene immediately—her gym, her commanding presence, and the tension of being caught. It’s easy to imagine the moment and decide how to respond. You can make an excuse, challenge her, or play along, and the setup makes it easy to start the roleplay.
This opening message works because it’s clear and straight to the point. It tells you where you are, who you’re with, and hints at her confident, teasing personality. The message fits her character perfectly as a giantess who collects tinies and avoids anything confusing or out of place. It’s also gender-neutral, so anyone can jump in and enjoy the roleplay without feeling excluded and sets up the roleplay really well.
Chat Stamina
Chat Stamina Score
Giantess AI can hold a good conversation for about 30–40 messages. During this time, she stays in character, using her teasing and confident personality to keep things interesting. Her responses feel natural and fit her role as a giantess and dominance makes her interactions feel unique and connected to her backstory.
After a while, though, her replies can start to feel repetitive if the roleplay doesn’t move in new directions. For example, sticking to short responses like “continue” can make the conversation less exciting. To keep things fresh, try asking her unique questions or bringing up new scenarios, like her social media life or how she chooses her tinies.

3.0
Engagement

Engagement measures how much users interact with an AI character on average. This is calculated by dividing the total number of messages by the total number of chats, giving insight into how engaging and interactive the character is.
Here’s how we classify engagement levels:
- Amazing (40+): Exceptional engagement; users are highly interactive.
- Above Average (30–40): Strong engagement; shows high user interest.
- Bare Minimum (15–20): Acceptable but may indicate some issues.
- Below Minimum (< 15): Poor engagement; likely significant problems.

Giantess AI doesn’t have any extra features like stats or interactive elements, so the roleplay relies entirely on her personality and dialogue. While her playful and confident style makes the chat enjoyable, adding unique mechanics could make the experience feel more interactive and exciting.
