A Fly Like Thee

A fly lands and walks across the screen. It is there because a bot has just crawled the page. »A Fly Like Thee«, a project by Olivier Jonvaux, is a plugin that brings these visits into view. Alongside it, a public live log names the bots behind them.

Every day, bots crawl ordinary websites (online shops, car garages, architecture firms, interactive platforms) and take everything they hold to feed AI models, without any consent or agreement. A Fly Like Thee is an open-source plugin that any website can install.

When a bot arrives (GPTBot, ClaudeBot, PerplexityBot), the plugin recognizes it by its signature and does two things at once. To people, it shows a trompe-l’œil fly landing on the page. To the bot, it writes a hidden quote inside the code itself, four lines by William Blake: »Am I not / A fly like thee? / Or art not thou / A man like me?« Serving one page to humans and another to machines is a search-ranking technique known as »cloaking,« here turned against its usual purpose.

The more a page is crawled, the more flies gather on it. A page the bots ignore stays clean; a page they return to fills with flies. They cannot be shooed away, they come back, and they only tell the truth: Something is feeding here. Blake’s four lines, meant only for the machine, count it among the living.

During the residency, Jonvaux will build and deploy the plugin, and launch a page hosted by Akademie Schloss Solitude keeping a public live log of every visit: which bot, which site, at what time. What is usually taken quietly now has a face and a name.
