Default engines
New projects start with Claude Opus 5.5, GPT-5.6 Sol and Gemini 3.8 Flash. Brands that sell to consumers, such as products people buy, book or visit, also get Google AI Overview, which Notra decides from your website during onboarding.Engines with web search
Notra runs every engine you select. Engines that can search the live web always run with search turned on, because that is how buyers see answers in ChatGPT, Claude, Gemini and Perplexity today.
These engines save the search queries they ran and the sources they cited. See How scans work and Citations.
Engines without web search
Some providers have no web search route in Notra: xAI Grok, Meta, Moonshot AI (Kimi), Z.AI (GLM), DeepSeek, Mistral AI and Cursor. Notra still runs them, but they answer from what the model learned in training, so their answers have no sources or search queries. The model picker and the results label these engines No web search. Compare them with each other rather than with search engines, because a model without search can’t see pages you published recently.Google AI Overview and coding agents
Notra fetches Google AI Overview from Google search results rather than a model API. Notra can also scan coding agents, where OpenCode, Claude Code and Codex research live while Cursor answers without web search.Coding-agent engines are available on request. Ask in Discord to enable them for your workspace.
