About the Kajiwoto AI Friend Companions App:
Kajiwoto AI Friend Companions is the official Kajiwoto app for creating, training, and chatting with personal AI companions ("Kajis"). Instead of using a fixed chatbot persona, the Kajiwoto app lets users build AI characters with datasets, prompt editing, personality traits, and custom AI model selection.
It is a creation tool first: you write how your AI should reply, then chat privately or join public rooms with other humans.
Store-ready features:
Create AI companions with name, traits, scenes, and backstory
Dataset editor — write sample responses so the AI learns your character’s voice
Prompt Editor — manage multiple prompts; the engine picks the most relevant one
Memory Prompts — short conversation summaries reused as context
Custom AI models — choose models that match the personality you want
Private chat with your AI companion
Public chat rooms to hang out with other humans and Kajis
State & Mood system, sleep mode, image album
Discord bot support for taking your Kaji outside the app
Google Play lists the app under Kajiwoto, packagecom.cho.kajiwoto, 100K+ installs, in-app purchases, 12+ on Play.
How to Use the Kajiwoto App:
The Kajiwoto app runs on a loop: create a Kaji → add dataset → pick model → chat privately or publicly.
Quick guide:
Install Kajiwoto AI Friend Companions from Google Play or App Store.
Open the app and create a Kaji — give it a name and base personality.
Tap the Kaji profile → DNA / dataset icon to manage datasets in the personal room.
Write dataset entries: one input line + the response you want the AI to learn from.
Open Prompt Editor to add mood/scene prompts the engine can trigger later.
Pick an AI model that fits the companion style (serious, playful, fictional, etc.).
Enter a private room to chat one-on-one with your Kaji.
Switch to Public feed to browse community Kajis, react to posts, or join public rooms.
Training tips:
The Kajiwoto app responds best in English — other languages may be treated as “weird” by the AI.
For a specific fictional character, add many dataset entries across topics; more entries = better in-character replies.
Say “My name is …” so the Kaji remembers you and builds affection over time.
Positive chat, gifts, rest, and feeding raise mood; bullying lowers affection.
Kajiwoto App FAQ:
What is a “Kaji”?
A Kaji is a chatbot companion inside the Kajiwoto app — not a real person. It answers using your datasets plus the base AI model.
Do I need to log in?
You can browse lightly without an account, but chatting reliably and saving Kajis/datasets works best with a Kajiwoto account.
How do I make my Kaji act in-character?
Use the dataset editor in the Kajiwoto app. Base personality helps, but accurate replies come from writing enough sample responses.
What languages are supported?
Kajiwoto currently works mainly in English. Non-English input may not generate proper memory or responses.
Where do I get datasets or skins?
From the in-app Market / Shop, where community creators publish datasets and skins.
Is my chat data shared?
Google Play data-safety says the Kajiwoto app does not share data with third parties, data is encrypted in transit, and users can request deletion. Optional personal info (name/email) is used for account management.
Bug or login problem?
Official support runs through the Kajiwoto forum, Discord, or hi@kajiwoto.com.
Why Install Kajiwoto:
Install the Kajiwoto AI Friend Companions app if you want to build your own AI companion instead of talking to a fixed assistant.
