Consensus vs NotebookLM vs OpenSEO

All three are research tools. Here is what separates them.

	Consensus	NotebookLM	OpenSEO
What it is	Answers a yes-or-no research question by aggregating what the papers actually found.	Grounds a model entirely in documents you upload, and will read the result back as a two-host podcast.	OpenSEO is the open source alternative to Ahrefs and Semrush. Keyword research, backlinks, rank tracking, and site audits, billed by usage instead of a $100-plus monthly subscription. Self-host it free, or connect it to your AI agents over MCP.
