SBTI
SBTI — Silly Big Type Indicator (Chinese slang expansion: 傻逼 / shabi) — is an internet-native personality quiz parodying MBTI. It scores 15 behavioural dimensions across five domains (Self, Emotion, Attitude, Action, Social), runs a Manhattan-distance match against 25 template patterns, and returns one of 27 archetypes like CTRL, DEAD, ATM-er, MALO, HHHH, or the DRUNK easter egg.
The quiz was created by Bilibili uploader @蛆肉儿串儿 and went viral April 9-11, 2026. The launch video crossed 2M views in 24 hours, the original site crashed, and WeChat Index for 'sbti' peaked at 40.85M on April 9. Dozens of English mirrors (sbti.ai, sbti.dev, whatssbti.com) appeared within days.
Within 48 hours of the Bilibili launch, English mirrors like whatssbti.com, sbti.guru and sbti.meme were live with translated questions. Developer tooling followed: serenakeyitan/sbti-wiki documents all 27 templates, nexu-io/sbti-skill packages the quiz as an AI-agent skill, and Chinese Google AI Studio builders posted SBTI landing pages vibe-coded in one evening.
What Doge did to currency — SBTI is shitposting in the shape of a personality test.

Why is it emerging now?
A Bilibili joke by @蛆肉儿串儿 crossed 2M views in 24 hours and drove WeChat Index to 40.85M on April 9, 2026. English SERP is still catching up — dominated by racing mirror sites, not canonical reporting — which is exactly the EarlyTerms window. MBTI fatigue in China made the inverted, shitposty frame land.
Outlook
6-month signal projection and commercial timeline.
All markers of a fast-burning meme (40M+ searches, domain grab, English ports, AI-skill/meme-coin derivatives) but viral quizzes typically peak in 2-6 weeks.
Risk · Bilibili has quietly removed the creator's original video and hashtags — a moderation signal that can choke Chinese oxygen fast.

Competition & Opportunity for term “SBTI”
Three heuristic signals derived from the tracked queries, the term's monetization cards, and its cluster neighbors. Directional, not audited.
Ideas for term “SBTI”
Buildable pitches — turn this term into an article, site, product, post, newsletter, video, or course. Steal any card and run with it.
As of April 17, 2026 the English SERP has no dominant canonical explainer — just mirror sites and wire-service rewrites. A careful piece covering the 15 dimensions, 27 types, creator story and MBTI contrast can rank on day one.
Readers arriving from 'sbti vs mbti' queries want a side-by-side. Map the five SBTI models (Self, Emotion, Attitude, Action, Social) to MBTI's four dichotomies and be honest about clinical legacy vs shitposting.
Developer-facing angle. nexu-io/sbti-skill and Chinese builder posts show SBTI being adopted as agent-persona shorthand. A tutorial that has Claude, GPT and Gemini self-report their SBTI will travel on X.
sbti.ai, sbti.dev, sbti.meme, whatssbti.com — a case study in how fast Chinese internet memes now get namespaced in English TLD space. Good for SEO newsletter and indiehacker audiences.
No single English-language site owns the category yet; mirrors compete on raw hosting. A proper directory — all 27 types with deep URLs, canonical test, leaderboard — could win on depth.
Ship an API that takes an SBTI code and returns a system prompt, voice profile, and conversation style. Targets character-chat and agent-persona builders who want vocabulary users already know.
Turn the 15-dimension framework into a team-compatibility tool — sidestepping MBTI's trademarked corporate turf. Keep the humour but add persistence and shareable team dashboards.
Media sites want the quiz inline. A white-label widget (your branding, standard 27-type logic, localised questions) is the cleanest play while the meme is hot.
In the same week that builders vibe-coded SBTI pages on Google AI Studio, Chinese AI communities started asking: what's your agent's SBTI?
Everyone is sharing their DEAD, CTRL or ATM-er result. Almost no one is reading the JavaScript underneath.
On April 8, @蛆肉儿串儿 posted a test to convince one friend to stop drinking. On April 9 WeChat Index logged 40.85 million searches.
