Deep Research is the most thorough option. It searches across your uploaded files, project context, and indexed documents to give you the most detailed, high-quality response. It takes longer, but the output is significantly more comprehensive. We always recommend Deep Research when accuracy and depth matter.
Regular is the standard mode. It gives you good-quality responses and is faster than Deep Research — ideal for quick questions or when you don't need an exhaustive answer.
Web searches the internet and draws on the AI's general knowledge, but it does not reference your projects, uploaded files, or Library. Use this when you need external information — product data, standards references, general industry knowledge — rather than anything specific to your project.
In short:
Deep Research → Highest quality, uses your project context, takes longer
Regular → Good quality, faster, simpler queries
Web → Searches the internet only, no project context
For specification-related or project-specific questions, Deep Research will almost always give you the best results.
