Consensus vs OpenSEO vs Parent.wiki

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

	Consensus	OpenSEO	Parent.wiki
What it is	Answers a yes-or-no research question by aggregating what the papers actually found.	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.	Sourced answers to parenting questions from AAP, CDC, and trusted institutions — plus real parent perspectives and practical next steps.
