Custom AI girlfriend FAQ

Q1. Is building a custom AI girlfriend hard?+
No. Kales uses a no-code visual builder — fill in a form, pick presets, and you have an AI girlfriend in about 3 minutes. Zero programming knowledge needed.
Q2. How much can I customize?+
Personality (14 presets — tsundere, yandere, cool, maid, imouto and more), looks (hair, body type, outfit, age), voice (formal, casual, slang, pet names), hobbies, backstory, and your relationship dynamic. Every layer is editable.
Q3. What about her image?+
Pick from a style picker (hair color, outfit) or describe her in an AI image prompt. Kales generates several candidates so you choose the one that matches your vision.
Q4. Can I edit her after she's created?+
Yes. Personality, voice and looks are editable any time. Memory is stored separately, so your past conversations carry over even when you tweak her settings.
Q5. Anime style or realistic — can I do both?+
Both. Anime, photorealistic, fantasy, sci-fi — pick the visual style that fits your character. Switch styles later without losing her personality.
Q6. Is my custom AI girlfriend private?+
By default, yes — she's saved as a private character only you can chat with. You can opt to publish her to the public library if you want other users to try her.
Q7. Can I teach her my preferred tone with example messages?+
Yes. Write 3-5 sample lines in her voice and the model picks up the rhythm. Showing example dialogue beats writing abstract descriptions.
Q8. Does Kales support GL / lesbian roleplay?+
Yes. Kales is gender-agnostic — you can build any pairing, F/F included, with natural roleplay dynamics and no awkward refusals.
Q9. Custom characters vs the 500+ presets — which should I pick?+
Use the 500+ presets when you want a fast start with a known archetype. Build a custom one when you have a specific vision — favorite trope, a unique mix, your own original character. Most users run both side by side.
