Published: · Updated:

Yonsei University researchers introduced Web$hell, an interface that brings web search, page interaction and revisiting previously gathered evidence into one system for AI agents. WebContract compiles pages into information and action objects; WebCache stores page states so agents can inspect earlier versions after an interaction.
In experiments, Web$hell used an average of 17.6 interaction turns per task on DeepWeb-Bench research tasks, compared with 52.4 for CLI-Any-Browser. The authors also report performance gains on web-search, navigation and multi-source research benchmarks. These measurements reflect specific agents, interfaces and benchmark settings; they do not establish success across general web use.
