Q&A
FAQ
We focus on core LINE markets, Thailand and Japan, and also support Southeast Asian markets such as Malaysia and Indonesia. Registration rates vary by country; Thailand and Japan have the highest LINE penetration, with the most complete accuracy (≥98%) and data coverage. Test a small sample first before deciding on large-scale filtering.
Yes. GeekNums has optimized its algorithms for exactly this: the AI avatar model is trained on real photos, cartoon/anime avatars and illustrations, and cross-checked with nickname semantics and Status Message text. Users with blurry avatars, non-person photos or highly anonymous profiles are marked "profile uncertain" rather than forced into a category, keeping results reliable. Overall gender accuracy is ≥85%.
Results export as TXT/CSV/Excel with fields compatible with LINE Official Account Manager's audience module, and can also be imported in bulk via the LINE Messaging API. Start with "valid + clear gender" data and use LINE's personalized message templates for precise outreach, for example beauty promotions for female users in Thailand or gaming news for male users in Japan. Gender is kept as a separate field so you can build gender-specific campaigns in the LINE OA dashboard.
