Perplexity
The only way I search for anything now; it gives me the real sources so I can actually trust what I'm reading.

The Assessment
- ✓ Search
- ✓ Research
- ✓ Facts
- ✓ Citations
- × Citations are often correct at the domain level but wrong at the specific-claim level — the paper cited may not say what Perplexity says it says.
- × Free tier uses a weaker model that noticeably underperforms Pro for complex questions.
- × Tends to over-summarise contested topics, smoothing out nuance that matters in academic or legal contexts.
The pricing reality
Unlimited standard searches on the free plan. Standard model quality, no file uploads, no API access.
Pro searches — which give deeper web synthesis and access to better models — are capped at 3 per day on free. File upload requires Pro.
Perplexity Pro at $20/month. Unlimited Pro searches, file uploads, image generation, and API access.
The Signal Guide
Treat this as your new default search engine. Instead of typing keywords, type full, complex questions. Create a 'Collection' for your current project, which forces the AI to only search within specific domains or PDFs you provide.

What Perplexity can’t do
It summarises the search. It can't tell you what to ask.
Perplexity is fast at synthesizing sources. The harder skill — knowing what question is actually worth asking, what counts as evidence, when to push past the easy answer — remains yours.
