Comparison

AlphaSense vs ChatGPT deep research

Answer in brief

Pick AlphaSense if your analysts need premium financial and business content, such as broker research, transcripts and expert calls, with citations back to the originals. Pick ChatGPT deep research if your team already pays for ChatGPT and needs a quick multi-source brief on the open web. 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.

Paid content against the open web

AlphaSense is built on content that open-web tools cannot reach. Its library includes equity research, expert interviews, filings and earnings transcripts, which are often paywalled. An analyst who needs what a broker said last quarter will find it there.

ChatGPT deep research works from the open web. It plans a set of searches, reads pages, and writes a long report. Its launch coverage describes web sources, and paid database access is not documented.

Citations and checking

AlphaSense provides clickable, granular citations to the underlying documents, which makes checking a claim straightforward. A separate fact-checking feature is not described.

ChatGPT deep research reports include sources, but OpenAI does not describe a separate claim check. Third-party reviews of ChatGPT mention hallucinations, though those reviews are not specific to deep research. Check any figure before using it.

Price and access

ChatGPT deep research is included in the ChatGPT plans, so a team that already has a subscription may have access. Limits differ by tier, and the pricing page uses labels rather than published counts.

AlphaSense is sold by quote, with seat-based and usage-based plans. Third-party data suggests a median contract near $18,750 a year, which is an estimate. Plan for a sales process.

Questions & answers

Is ChatGPT deep research good enough for market research?
