Comparison
If you are comparing alternatives to ChatGPT Atlas and agent modes, the practical difference is where the work happens. Switching to resolvenengine keeps actions inside your Chrome session and uses individually revocable connections with per-operation permissions, rather than moving the task into a vendor-hosted environment.
Cloud agent environments are useful for long, unattended work on public web content. People may look for another form factor when a task relies on the browser session they already use, requires access to separately connected work accounts, or needs each consequential operation governed outside the model.
resolvenengine is the better fit when you want existing Chrome sessions, visible browser actions, revocable service connections and Allow, Ask or Deny rules per operation. ChatGPT's agent modes remain the better fit when bundled frontier models and unattended cloud runs matter more than working in your own browser environment.
