Abstract
Democracy relies on citizens' collective intelligence, a foundation now severely undermined by information manipulation.
Since 2016, Cofacts has built an open-source, wiki-like collaborative fact-checking platform. It empowers citizens who care about disinformation to write responses, directly communicating with users who receive hoaxes in closed messaging apps.
Over the past decade, handling disinformation has been inherently challenging: the same hoax often mutates across text, screenshots, and videos. The recent popularization of generative AI has made the verification exceptionally difficult. Furthermore, our offline workshops highlight a critical bottleneck in crowd-sourced defense: despite widespread anxiety over disinformation, the barrier to entry remains dauntingly high. The fear of making mistakes often paralyzes volunteers, leading to severe self-doubt and rapid burnout.
In the face of asymmetric information warfare, AI is both a challenge and an opportunity. This session will walk through the pain points experienced by community fact-checkers and Cofacts' journey in building open-source technological solutions. We will explore how to position AI as an "assistant" rather than a "replacement"—ensuring that human agency is preserved while guiding citizens to overcome verification barriers and collectively join the movement to defend against information manipulation.

Cofacts 專案發起人與核心開發者。長期致力於透過開源技術與群眾協作,對抗 LINE 上的不實訊息。近年專注於探索 LLM 應用落地與系統架構開發,致力於降低群眾查核門檻,期盼藉由科技陪伴公民社會一同面對資訊操弄的挑戰。
I founded the Cofacts project in 2016 and serve as its core developer. Cofacts is an open-source civic tech project dedicated to fighting disinformation on closed messaging apps.
Over the past few years, my work has focused on integrating emerging technologies, such as LLMs and semantic search algorithms, into our system. I also host weekly open meetings to maintain project transparency and engage with the community, ensuring our open-source journey is accessible to everyone interested in civic tech.

Cofacts 貢獻者、邊緣人,原本是打(算)滾(出) 遊戲業的 Unity 工程師,2018 年剛好手上專案比較閒,就在工作時間研究 web 前後端、發了一個 PR 進 Cofacts,然後就越做越多。自詡是 Cofacts 的「清潔工 程師」,一路都在修 bug、做小功能,做著做著反而變成把在 Cofacts 學到的東西拿回工作上用。
想要告訴大家一開始點錯技能樹不用懊悔,只要加入開源社群就好(X
