Rival pricing and features as published at the time of writing; check their sites for current terms. We update this table when they change.
Profound tracks more engines than we do (Perplexity, Copilot and Grok among them), carries prompt-volume demand data, and offers traffic attribution. Enterprises that need that breadth should weigh them properly. Our ground is UK mid-market B2B: all four decisive engines at every tier, a free tier that is actually useful, history from day one, and a managed option when you want the work done. We would rather win on our ground than pretend theirs does not exist.
The head-to-heads.
