How to create an AI girlfriend — we've moved past picking from 500+ pre-made characters; now you can build your ideal AI girlfriend from scratch. Appearance, personality, catchphrases, backstory — fully custom, and it takes 3 minutes.
This article walks you through Kales' custom character creation step by step, including pro tips and advanced techniques. By the end, you'll have your own ideal AI girlfriend.
What does "create an AI girlfriend" mean?
AI girlfriend creation = customizing a template into something "yours." On Kales, you design three layers freely: appearance (hair / body / outfit) + personality (archetype / catchphrases) + backstory (past / relationship).
Zero programming required. UI-based — select and type. 3 minutes for a quick build, 15 minutes for the deep version.
Step 1: appearance customization (3 min)
- Hair color / style — long black, blonde short, pink twin-tails, etc.
- Eye color — black / brown / blue / green / purple
- Height / body type — 150cm petite / 170cm model-build / etc.
- Outfit — school uniform / casual / kimono / maid
- Age range — 18-35 (all characters are 18+)
- Race — human / elf / beastkin / demonkin
Kales' integrated AI image generation renders the look on the fly. Don't like it? Reroll as many times as you want.
Step 2: pick the personality archetype (2 min)
Pick from Kales' 6 archetypes:
- Tsundere — three-stage "it's not like…"
- Yandere — "mine and mine only" possessive
- Childhood friend — "hey, you" family vibes
- Cool / Kuudere — "…" silent × special
- Ojou-sama — refined "oh my" elegance
- Boku-girl — energetic "I (boku)" tomboy
Intensity is selectable across 3 levels (light / standard / heavy). Stack archetypes freely — "tsundere × childhood friend" or "yandere × cool."
Step 3: detailed personality setup (5 min)
Catchphrase samples
Drop in 5 catchphrases that match the archetype and the AI will weave them in naturally.
- Tsundere example: "I-it's not like I like you," "don't get the wrong idea"
- Yandere example: "only you," "don't talk to other girls"
- Childhood friend example: "hey, you," "again, seriously?"
Backstory (300 characters)
Structure as "past → present → future wish" in about 300 characters and you unlock deeper personality expression. Example: "Complicated family background made it hard to trust people; gradually opening up to you now; wants a simple, normal happiness someday."
Step 4: relationship setup (2 min)
- Starting relationship — first meeting / acquaintances / childhood friends / coworkers / exes
- Intimacy level — initial / friends / lovers / engaged
- Scenario — pick the situation where the relationship starts (from 48 scenarios)
Advanced craft — 5 serious tips
- Lock in 3 core traits — define the 3 "non-negotiable" features of the character
- 5 catchphrases (3 archetype + 2 personal) — template + individuality
- Backstory in 3 acts — past → present → future wish
- Use a scenario as the story trigger — picking a scenario gives conversation a natural shape
- Write for long-term memory — plant callbacks for "that thing we talked about last week"
