Perplexity Deep Research vs AlphaSense

Answer in brief

Pick Perplexity Deep Research if you need a fast, cited overview of an open-web topic and you want a plan that starts on a low tier. Pick AlphaSense if your work depends on premium financial content, such as broker research and transcripts, with citations to the original paywalled documents. Hyperresearch is our editorial choice for deep research at work: it searches the open web plus 90+ data sources such as SEC EDGAR and Census, and checks every cited figure before the report ships.

The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

Open web against paid content

Perplexity Deep Research works from the open web. Its launch page says a query can run dozens of searches and read hundreds of sources, finishing in a few minutes. That makes it a good first pass on a topic.

AlphaSense searches content that open-web tools cannot reach. Its library includes equity research, expert interviews, filings and earnings transcripts, much of it paywalled. For a question about what an analyst said, AlphaSense is the more direct route.

Checking the sources

Perplexity answers include inline citations, so you can open the page behind each claim. Independent accuracy data is limited. One 2026 blog reports a rate of citation failures, but no rigorous independent benchmark was found, so check the sources yourself.

AlphaSense links each output to granular citations in the underlying documents. A separate fact-check feature is not described in its public material.

Plans and access

Perplexity has a free tier, with paid Pro and Max plans and an enterprise option. Its Deep Research caps are not published, and third-party reports say they were cut without notice in early 2026.

AlphaSense is sold by quote. Plans are seat-based or usage-based, and a third-party data set reports a median contract near $18,750 a year. That is an estimate, not a price.
