OpenRouter has a laser focus on bringing a great developer experience to all language models, and Exa is the best way we've found for grounding AI in the real world in a model-agnostic way.
Exa's powerful search capabilities have been instrumental in delivering the high-quality, relevant web content our users need while maintaining our commitment to privacy and user control.
This is so powerful. Exa is like Perplexity-as-a-service. The infrastructure to ground your AI products on real world data and facts.
Exa's strong coverage and flexible API have been a key differentiator for us. Scientists trust our product further when the relevant papers they expect to see are available to them in the right workflows. The ability to customize search based on the use case easily, is important.
When we saw companies show up in Exa that we hadn't found anywhere else, we knew it was our best option. It delivers, for a few dollars, what we'd been spending hundreds of thousands to assemble.
We use Exa for essentially all parts of our research—gathering sources, documenting, creating notes, and building briefs.
StackAI and Exa are the dream team…Exa is amazing at web search! We're proud to use Exa on our platform and to show our customers how web search can power AI agent workflows.
Models are only as good as the data they're trained on, and Exa's search allowed us to get high quality data we couldn't find any other way.
