AI Hay
The Vietnamese-first AI Q&A app your customers are already using
AI Hay is a Vietnam-built AI Q&A app best for Vietnamese consumer brands, marketing teams researching Vietnamese-language search intent, and education businesses targeting Vietnamese students. Its Vietnamese-first answers with local source citations plus a social Q&A feed offer research signal that ChatGPT and Gemini do not surface for SEA marketers. The trade-off is consumer focus — it is not a B2B AI infrastructure tool, and businesses should treat it as a research artefact rather than a deployable platform.
- ✓Vietnamese-first answers with citations to local sources beats global LLMs on Vietnam-specific topics
- ✓Social Q&A feed shows how Vietnamese users actually phrase questions about brands and products
- ✓Image and PDF input handles bills, forms, and homework for consumer use cases
- ✓Multi-model routing with Vietnamese-tuned fine-tuning under the hood
- ✓Affordable Pro tier at roughly 100,000 VND per month for unlimited usage
- ×Consumer app, not a B2B AI platform — no API or enterprise infra
- ×Languages limited to VI and EN, so utility outside Vietnam is narrow
- ×Free tier likely has usage caps that force serious researchers to Pro
- ×Useful as a research signal, but not a deployable customer-facing tool

The questions operators actually ask.
Can I use AI Hay for English questions?
Yes, but it is Vietnamese-first. EN is supported but the platform's moat is Vietnamese-language answers and citations to local sources. For pure English Q&A, ChatGPT or Claude are stronger.
Is AI Hay better than ChatGPT for Vietnamese users?
For Vietnam-specific topics like local services, brands, and current events, yes. AI Hay surfaces Vietnamese sources and conversational patterns that ChatGPT misses. For general programming or English-language research, ChatGPT still wins.
Can businesses use AI Hay as a research tool?
Yes. SEA marketers can use it to understand how Vietnamese consumers ask questions about products and services, which is a signal ChatGPT will not provide. It is research artefact use rather than direct customer deployment.
What does AI Hay Pro cost?
Roughly USD 4 per month or 100,000 VND per month for unlimited usage. That is consumer-grade pricing aligned with Vietnamese disposable income, far below US AI tool subscriptions.
