Google DeepMind's experimental AI browser agent that could navigate Chrome, fill out forms, book travel, and complete web tasks by taking screenshots and clicking for you. Killed after 17 months, with no big announcement, when staff were reassigned. The tech was absorbed into Gemini Agent. Privacy concerns and high compute costs for visual processing made it unsustainable.
Collateral damage: Early testers lost their web automation workflows. Saved routines and trained behaviors didn't transfer to Gemini Agent.
