I built a free AI text humanizer with dual-engine fallback

Описание и применение

Автор создал бесплатный инструмент для «человечивания» текста с резервным AI‑движком, чтобы избежать ограничений и скрытых платежей, внедрив строгий лимит использования и защиту от ботнетов.

Задача

Free AI tools often impose hidden charges after a limited word count, and rate limits can disrupt service reliability.

Результат

The dual-engine PHP implementation provides uninterrupted humanization service with a daily limit to mitigate abuse, while bundling additional webmaster tools for broader utility.

Рабочий процесс

• 1. User visits sitetoolsbox.com
• 2. Navigates to the AI section
• 3. Inputs text to be humanized
• 4. The system queries OpenRouter; if rate‑limited, falls back to SiliconFlow
• 5. Returns humanized text to the user

Доказательства

I got tired of "free" AI tools that actually charge you after 200 words.

It's a dual-engine setup (OpenRouter + SiliconFlow) written in pure PHP so it shouldn't crash when the API gets rate-limited.

Источник

I also added a strict daily limit (5 uses per IP) because a botnet attacked my endpoint 50 times right after I launched it.
