## Executive Summary
Goal: SEA AI-localised promo copy — why 2026-10-05
Shoppers across Southeast Asia demand culturally authentic, accurate promotional copy; over two-thirds (67.5% for next sale, 68.1% for default) insist on AI localisation combined with native-speaker verification, rejecting fully autonomous unchecked AI. Deploying unchecked AI copy risks severe churn: 77.6% cite culturally tone-deaf copy as their top reason to mute notifications, 69.7% lose trust when seeing garbled text, and 55.7% would switch shopping to a competitor with verified promos.

## Key Findings
- Shoppers overwhelmingly prefer a hybrid 'AI-localised + native-speaker check' workflow (67.5% next sale, 68.1% 6-month default), while 99.2% insist on pre-send human or community validation. _(confidence: high)_
- Unchecked AI generation triggers severe business churn: cultural blunders are the #1 mistrusted error (77.6%), 69.7% report low trust (scores 1-2) from garbled text, and 55.7% will switch to a competitor. _(confidence: high)_
- Casual slang and emoji rewrites polarise users: 63.6% cite brand slang as try-hard/unprofessional, and 45.9% are less likely to tap slang-heavy copy compared to standard natural language. _(confidence: high)_
- AI disclosure is contingent on quality: 48.7% require AI labelling only if no human checked it, while 16.2% find disclosure unnecessary once human-reviewed (31.4% demand unconditional labelling). _(confidence: high)_

## Segment Insights
- **Local-Language Primary Shoppers** (45.9%): Heavily dependent on verified local copy; 78.7% demand AI + native review (highest across groups) and only 3.7% accept slang rewrites. Fully autonomous AI is rejected (only 12.8% accept it).
- **Bilingual Code-Mixed Shoppers** (28.3%): Most receptive to colloquial experimentation; 21.8% favour AI slang/code-mixed promos and 61.4% prefer AI + native checks, displaying greater flexibility for casual brand communication.
- **English-Only Promo Recipients** (25.5%): Retain significant attachment to English copy (17.6% prefer English-only default), yet 54.9% still favour verified local translation when offered, prioritising accuracy over local slang.
- **High-Frequency App Shoppers (Weekly / Few times a month)** (81.8%): Account for 81.8% of the user base; 53.8% will switch to a competitor and 29.1% will decrease app activity upon encountering persistent unchecked AI errors, representing immense GMV risk.

## Recommendations
- **[high]** Institutionalise a mandatory 'Human-in-the-Loop' (HITL) gate for all AI-localised promotional campaigns, ensuring native speakers verify tone, cultural nuances, pricing, and deadlines before dispatch.
- **[high]** Implement cultural nuance and sensitivity safety filters in the LLM prompting and evaluation layer to eliminate culturally inappropriate phrasing, which drives 77.6% of notification churn.
- **[medium]** Default to polished, natural standard local language rather than aggressive slang or heavy emoji code-mixing, reserving colloquial phrasing only for specific youth-oriented sub-brands where brand fit is verified.
- **[medium]** Establish transparent labelling protocols: clearly flag autonomous AI-generated messages if unreviewed, but reserve prominent disclosure real estate when native-speaker QA is maintained.

## Limitations
- Demographic fields (age, gender, location) were blank in the dataset, precluding micro-segmentation by specific SEA country (e.g., Indonesia vs. Thailand vs. Vietnam) or age demographic brackets.
- Responses reflect stated behavioural intent regarding competitor switching, which should be calibrated against observed transaction retention metrics.
