The Hudson Labs Co-Analyst
Consistent. Reliable. Factual.
Create structured tables from earnings calls, compare commentary across peers, and consistently extract guidance. Access the Co-Analyst on Hudson Labs in beta at platform.hudson-labs.com/coanalyst.
How to use
The Hudson Labs Co-Analyst beta is a specialized tool designed to extract and organize data in earnings call transcripts. It is not a chatbot and should not be used like one.
Toggle to the web search mode to ask for information better answered through public sources on the internet. Click the web icon in the input box to switch between modes. Use the Web mode as you would use Google, see more examples later in the guide.
Library mode
1. Select a company (or up to 3)
Select any U.S. public company, provided they have held an earnings call and published at least one 10-K. Use the ticker or name to find a company of interest.
Multi-quarter search is only available when a single company is selected, while in beta.
2. Search for a KPI, topic, or theme
Search using words and terms that exist in earnings call transcripts or pre-defined “meta queries” (refer to the meta query section below). The Co-Analyst can only provide answers using information it has access to i.e. information in earnings call transcripts from January 1, 2023 until now.
Find a list of suggested searches in our guide below.
Tricks for queries:
- Add “$X Y%” to get a numeric-focused response
- Type out acronym definitions (e.g. “commercial real estate” over “CRE”)
- Specify whether you want to see actuals or guidance.
- For more completeness and detail, narrow your search i.e. ask for a single KPI for a shorter time period.
3. Optional: Give instructions on how to display your answer
If no instructions are provided, the Co-Analyst will guess the best format for the output. We do a pretty good job of guessing!
If you don’t get the output you want the first time, try specifying exactly what columns and rows you’re looking for in a table or ask for the information in a bulleted list or paragraph.
How not to use the Co-Analyst
The query input box is meant for key terms and meta queries only. That means you should NOT ask for a specific company name, use the phrase “earnings call”, nor ask for a specific time period in your query.
Instead make company and date selections on the left hand side of the screen. Like this:
Why not?
We are performing a “search” across the relevant database using the key words provided in the query box.
Only use words that you want to be matched in that search. For instance, in the image above, we would try to match references to “most recent”, “earnings call” and “apple” which is likely not what you wanted. Meta queries are the one exception to this rule.
Meta queries for the “Most recent” call
Meta queries use specific words (not seen in earnings calls) to prompt the Co-Analyst to perform a specific task. Meta queries work best with a single company’s most recent call:
Guidance
Use the meta query “guidance” to get a complete table with all quantitative and semi-quantitative guides
Nvidia guidance for the most recent quarter
Query: Guidance
**Notice that the Co-Analyst accurately calculates the lower and upper end of guidance from the source:
Summarize
Use the phrase summarize + {topic} for summarized results. We suggest narrowing your summary request given that the output length is limited. However, you can find full earnings call summaries on our platform under the Filings & transcripts section of the company page. Here is an example from Nvidia.
Nvidia call questions & answers
Query: summarize top questions and answers
Instructions: table
Negatives and Headwinds
Home Depot negative statements from the most recent call
Query: list negatives
Cross-company comparison
Easily compare comments on the same topic at different companies. Select up to three companies for comparison. Only the most recent earnings call can be used in this workflow.
Compare
Use this meta query to get a comparison of overlapping metrics and KPIs.
Comparison of the Cava Group and Sweetgreen KPIs discussed in their most recent calls
Query: compare
Thematic
Artificial intelligence at Microsoft and Alphabet
Query: artificial intelligence
Instructions: compare all aspects
China exposure at Steven Madden and Boot Barn
Query: China exposure
Instructions: table
Multi-period comparison
Assess how commentary and KPI disclosure has evolved over time for a specific topic. By default the Co-Analyst will provide information on all quarters going back to 2023.
Backlog at Workday
Query: backlog
DIY vs. pro customers at Lowes
Query: DIY vs Pro
Subscribers at Paramount
Query: subscribers
Web search
(Updated on February 20) Use the web search to supplement the information missing from the earnings transcripts. Ask more complete questions as you would use Google or any traditional search engine. Click the web icon in the input box to switch between modes. Filters and instruction boxes are disabled for simplicity.
Use the web mode for generalist queries or information, instead of gated data like detailed financial metrics.
Try the web mode with some sample queries below:
Query: who are Danaher’s competitors in the diagnostics space?
Query: c3ai management team, provide table with name, position and tenure
In-text citations are also enabled to trace the sources directly in the output. Click on a number to open the corresponding source website. The entire list is also available on the right under the Sources section.
Query: what is the street saying about AppLovin?
We are bringing this feature to the core Co-Analyst soon. Meanwhile, links to earnings transcripts are available at the top of the output for easy reference.
Copying to excel
Use the copy button on the top right of the output to copy your output directly to a spreadsheet.
You can also copy each table individually.
Sourcing & factuality
The Co-Analyst organizes existing information in earnings calls. During the beta testing period, we are unable to provide a direct connection between each cell of a table and each source sentence. However, all information will be factual, non-hallucinated and come straight from the call.
You may see occasional reasoning errors i.e. not understanding whether a figure relates to the full annual period or the quarterly period. This is most often the case when the transcript does not make this distinction clear. However, you will never see fabricated information.
Stay tuned for new and easy auditability and sourcing coming soon.
In the interim, if you would like to view the verbatim statement from the earnings call in your output use the following instructions. Please copy the instruction wording exactly. Using these sourcing instructions may decrease the level of detailed received in your response.
Instructions: provide verbatim citation as a column in the table
The Co-Analyst continues to get great reviews. Users are increasingly using it for earnings call previews and reviews, with weekly queries doubling since the December launch.
To help us continue improving, you can now easily provide feedback on query outputs. Simply click the thumbs-up or down button to indicate whether the Co-Analyst provided the information you needed.
