Using Exa's link similarity search to find related links
Using the keyword search setting with Exa search_and_contents

In this example, we'll build a company analyst tool that researches companies relevant to what you're interested in. If you just want to see the code, check out the Colab notebook.

The code requires an Exa API key and an OpenAI API key. Get 1000 free Exa searches per month just for signing up!

Shortcomings of Google

Say we want to find companies similar to Thrifthouse, a platform for selling secondhand goods on college campuses. Unfortunately, googling “companies similar to Thrifthouse” doesn't do a very good job. Traditional search engines rely heavily on keyword matching. In this case we get results about physical thrift stores. Hm, that's not really what I want.

Let’s try again, this time searching based on a description of the company, like by googling “community based resale apps.” But, this isn’t very helpful either and just returns premade SEO-optimized listicles...

What we really need is neural search.

What is neural search?

Exa is a fully neural search engine built using a foundational embeddings model trained for webpage retrieval. It’s capable of understanding entity types (company, blog post, Github repo), descriptors (funny, scholastic, authoritative), and any other semantic qualities inside of a query. Neural search can be far more useful than traditional keyword-based searches for these complex queries.

Finding companies with Exa link similarity search

Let's try Exa, using the Python SDK! We can use thefind_similar_and_contents function to find similar links and get contents from each link. The input is simply a URL, https://thrift.house and we set num_results=10(this is customizable up to thousands of results in Exa).

By specifying highlights={"num_sentences":2} for each search result, Exa will also identify and return a two sentence excerpt from the content that's relevant to our query. This will allow us to quickly understand each website that we find.

!pip install exa_py

from exa_py import Exa
import os

EXA_API_KEY= os.environ.get("EXA_API_KEY")

exa = Exa(api_key=EXA_API_KEY)
input_url = "https://thrift.house"

search_response = exa.find_similar_and_contents(
        input_url,
        highlights={"num_sentences":2},
        num_results=10)

companies = search_response.results

print(companies[0])

This is an example of the full first result:

[Result(url='https://www.mystorestash.com/', 
        id='lMTt0MBzc8ztb6Az3OGKPA', 
        title='The Airbnb of Storage', 
        score=0.758899450302124, 
        published_date='2023-01-01', 
        author=None, 
        text=None, 
        highlights=["I got my suitcase picked up right from my dorm and didn't have to worry for the whole summer.Angela Scaria /Still have questions?Where are my items stored?"], 
        highlight_scores=[0.23423566609247845])]

And here are the 10 titles and URLs I got:

# to just see the 10 titles and urls 
urls = {}
for c in companies:
  print(c.title + ':' + c.url)

Swapskis:https://www.swapskis.co/
Earn Money for Used Clothing:https://www.thredup.com/cleanout?redirectPath=%2Fcleanout%2Fsell

Looks pretty darn good! As a bonus specifically for companies data, specifying category="company" in the SDK will search across a curated, larger companies dataset - if you're interested in this, let us know at [email protected]!

Now that we have 10 companies we want to dig into further, let’s do some research on each of these companies.

Finding additional info for each company

Now let's get more information by finding additional webpages about each company. To do this, we're going to do a keyword search of each company's URL. We're using keyword because we want to find webpages that exactly match the company we're inputting. We can do this with the search_and_contents function, and specify type="keyword" and num_results=5. This will give me 5 websites about each company.

# doing an example with the first companies
c = companies[0]
all_contents = ""
search_response = exa.search_and_contents(
  c.url, # input the company's URL
  type="keyword",
  num_results=5
)
research_response = search_response.results
for r in research_response:
  all_contents += r.text

Here's an example of the first result for the first company, Rumie App. You can see the first result is the actual link contents itself.

Creating a report with LLMs

Finally, let's create a summarized report that lists our 10 companies and gives us an easily digestible summary of each company. We can input all of this web content into an LLM and have it generate a nice report!

import textwrap
import openai
import os

SYSTEM_MESSAGE = "You are a helpful assistant writing a research report about a company. Summarize the users input into multiple paragraphs. Be extremely concise, professional, and factual as possible. The first paragraph should be an introduction and summary of the company. The second paragraph should include pros and cons of the company. Things like what are they doing well, things they are doing poorly or struggling with. And ideally, suggestions to make the company better."
openai.api_key = os.environ.get("OPENAI_API_KEY")

completion = openai.chat.completions.create(
    model="gpt-4",
    messages=[
        {"role": "system", "content": SYSTEM_MESSAGE},
        {"role": "user", "content": all_contents},
    ],
)

summary = completion.choices[0].message.content

print(f"Summary for {c.url}:")
print(textwrap.fill(summary, 80))
