PenIdea explores the edge of AI and everyday apps. We put intelligence in unexpected places, redefining what it means. — Like asking your boss for a day off.
Founded in 2025, PenIdea (笔创科技) is an AI-first company building intelligent applications for everyday consumers. Our mission is to make the power of large language models accessible, practical, and genuinely useful for real people.
We build tools that help you understand yourself better, make decisions, and connect with others. We believe the real technological revolution isn't about replacing people — it's about giving everyone the power to surpass their own limits.
Real products, live today — built in-house and shipping to users around the world.

The biggest difference is that RDPI's archetypes are derived from a model built on statistical modeling of large-scale Big Five personality samples — comprising 6-digit personality cluster codes across 36 centroids, with a theoretical ceiling of over 20 billion personality types. We believe everyone is unique, and we deliver a tailored personality profile across dozens of dimensions.
Qarot is our mobile application targeted specifically at the international market and is available in multiple languages. It is not currently available in the mainland China App Store.
Our AI-powered Instant Messaging platform (PI+) is currently in development. It is being built from the ground up with deep AI integration — not bolted on after the fact. We will announce availability when ready.
PenIdea currently focuses on building consumer (C-end) applications. We do not license or expose our in-house / fine-tuned psychological and narrative model APIs for now.
