Who should pick which

  • AI developer building a RAG pipeline
    Pick: Spider Cloud

    Spider Cloud offers real-time web crawling, structured output, and integrations with LangChain/LlamaIndex, making it ideal for feeding up-to-date data into RAG systems at low cost.

  • AI safety researcher auditing model behavior
    Pick: Steerling

    Steerling's inherently interpretable models and Clarity platform enable prompt-level analysis and steering, essential for auditing and control in high-stakes AI applications.

  • Solo founder scraping e-commerce data
    Pick: Spider Cloud

    Spider Cloud's freemium pricing, browser AI commands, and ready-made scraper catalog lower the barrier for small-scale scraping without upfront costs.

  • Regulatory compliance officer
    Pick: Steerling

    Steerling's focus on auditability and transparency provides the documentation and control needed to comply with emerging AI regulations.
