Why Social Toolkit?
System prompt anchors a 'Vietnamese content creator with 5 years experience' + few-shot Vietnamese examples. No machine translation, understands Gen Z slang.
Facebook caption ≠ TikTok hook ≠ Instagram bio. Each platform has dedicated prompts for format, char limit, hashtag style.
Caption + Hook tools stream text realtime — see results in <1s instead of waiting 5-10s.
Each request goes to Anthropic, server doesn't log content. Rate limit 20 gen/hour/IP.

Frequently asked questions
Which AI model do you use?
Anthropic Claude Haiku 4.5 — the fastest, cheapest model that still handles Vietnamese natively. Each request costs ~40 VND, so we can offer 20 generations/hour/IP for free.
Any limits?
Rate limit 20 generations/hour/IP to prevent abuse. Plus a $5/day server-wide budget cap — if exceeded, requests pause until next UTC midnight (rare in practice).
Do I need to sign up?
No. Fully anonymous, no email, no account. Each IP has its own quota based on cf-connecting-ip header.
Is the AI output accurate and creative?
Claude Haiku 4.5 is a premium Anthropic model that understands Vietnamese culture, Gen Z slang, platform formats. Still, AI needs human curation — we generate 5-10 variations for you to pick the best, not just one 'final' answer.
Is there a history?
No. No database, no logs. Copy results immediately — refreshing loses them.
Can I use the outputs commercially?
Yes. AI outputs belong to you (per Anthropic terms). Use for content marketing, business pages, agency client work.
Does it support English?
Yes. UI toggles VI/EN, AI understands English prompts too. But the tool is most heavily optimized for Vietnamese — that's the differentiator vs ChatGPT/Copy.ai.
Can I use it like ChatGPT for free-form chat?
No. This is a specialized 4-tool app: caption, hashtag, bio, hook. For free-form AI chat, use Claude.ai or ChatGPT.
