Why use Exa
High Quality data
Instead of relying on low quality datadumps like commoncrawl, Exa's crawling infrastructure is optimized to find data from high quality sources.
Powerful Filters
Exa can filter the web based on natural language. You can filter by topic, idea, entity type, length -- pretty much anything you want.
Comprehensiveness
We can customize our crawling to fit any size that fits your needs: from a few million tokens to trillions.

Use case
Training a large context window model
Challenge
A leading AI company is trying to fine-tune its own LLM to handle long context windows for technical topics like programming, but cannot find high quality, long-form, technical content.
Solution
Using a few natural language queries, Exa is able to find high quality, long-form, technical content in math, science and programming that exactly match the fine-tuning goal of the company.
Impact
>10Btokens delivered

“Exa is good, really good. We went from multiple API calls and scraping into a single <1s fast call. The results are way different than traditional search, and way better. Our users love it!”
