Opposition source finding
Paste a URL. Oppi scrapes it, maps the argument, then searches the web for the most credible opposing source. Both sides shown side by side.

A new debate prompt each day — thoughtful questions on topics that matter, designed to make you think harder.
Organised by topic
Analyses grouped around the issues you care about. An organised space to build understanding — not a throwaway chat.

From link to debate in seconds
Drop a link
Paste any article URL. Oppi reads it, extracts the core argument, identifies the stance, and maps every key claim.
Oppi finds the counter
It searches the web for the strongest opposing source — not a weak rebuttal, but the most credible, best-argued case against the article you shared.
