Why focus modes exist

The open web is mostly noise for any serious question. A blog post and a peer-reviewed paper get the same starting weight in a generic search. Focus modes let you tell Perplexity 'only look in academic publications' or 'only YouTube transcripts' so the answer pulls from the source family that matches the question.

Quick guide

Focus	Use when	Watch out for
All / Web	General questions	Content farms in citations
Academic	Lit review, citing studies	Paywalls hiding key text
YouTube	Tutorial-style answers, demos	Transcripts miss visual nuance
Reddit	Real-world experiences, gripes	Anecdote != evidence
Writing / Math	Generation-only, no search	No fresh facts
Social	Sentiment, what's trending	Echo chambers

Pitfalls per mode

Academic: papers behind paywalls give thin abstracts, leading to surface-level citations
YouTube: relies on auto-transcripts that miss diagrams, so video-heavy topics suffer
Reddit: anecdotes can feel authoritative because of upvote counts; correlation is not evidence
Social: skews to whatever's loud this week, not what's true
Writing/Math: no retrieval at all — pure generation, with hallucination risk

Apply: rotate two modes per question

Pick a question with both a formal and a lived-experience side
Run on Academic, save the answer
Run on Reddit, save the answer
Reconcile the two — note where they agree and where they fight
Cite both in your final write-up

The big idea: focus modes are how you stop Perplexity from drowning your answer in content farms. Pick the mode that matches the question's source family.
