我们使用AI监控审查并扩大言论自由
我们的项目 关于我们

我们的影响

在GreatFire.org，我们利用尖端的中西方人工智能大规模对抗审查。我们的系统持续监控、分析和规避全球的审查机制。当局使用AI来监控和审查内容——我们用它来识别这些主题可能是什么。审查者使用AI来阻止信息访问——我们用它来寻找他们系统中的漏洞。

关于我们

我们是一家成立于2011年的中国反审查组织。我们积极应对并挑战中国当局的审查制度。我们运营着多个创新项目，这些项目解决了审查机制的不同方面，其中许多项目不仅在中国有用，在世界其他地区也有用。我们的工作已被数百项学术研究引用，我们的数据经常被主要新闻报道引用。中国当局认识到我们工作的重要性，并试图以前所未有的网络攻击破坏我们的运营，但未成功。
