AI research stack
For consultants, analysts, or journalists who need sourced summaries without confusing generative AI with a search engine.

Measurement & support
Measure, track, and understand what actually works.
Core: Perplexity. Add-ons based on your actual use.
Other steps
Useful tools that complete the workflow.
Core: Claude + Gemini. Add-ons based on your actual use.
$29/month, when the core stack earns its keep.
Frequently asked questions.
Do you use Perplexity's Focus or Spaces to filter your sources?
No → you get generic Web results when you could have targeted academic or sector-specific sources. Academic Focus alone justifies the subscription for anyone writing client synthesis notes.
Do you analyze recurring documents (quarterly reports, sector studies) for clients?
Yes → Claude Projects keeps the document in the context of all project exchanges, not just the current session. For recurring reports, the difference is structural.
Do you cross-check your AI summaries with primary sources before delivering?
No → one convincing hallucination in a client note costs more in credibility than you save in time. Perplexity + citation verification = non-negotiable minimum protection.
