Who should pick which

  • Enterprise RAG engineer
    Pick: Voyage AI

    You need domain-specific embeddings and rerankers with long-context support (32K tokens) and compliance certifications (SOC 2, HIPAA). Voyage AI's Batch API and low-dimensional vectors reduce costs at scale.

  • AI code agent adopter
    Pick: CodeBoarding

    If your team uses Cursor, Windsurf, or Claude Code, CodeBoarding provides live architecture diagrams and blast radius analysis to keep AI-generated code aligned with system design.

  • Startup prototyping RAG
    Pick: CodeBoarding

    Lacking budget for enterprise sales, you can start with CodeBoarding's freemium to visualize your codebase, but for search you might need an alternative with self-serve pricing.

  • Legal/finance compliance team
    Pick: Voyage AI

    Domain-specific models and compliance certifications directly address your need for accurate and secure document retrieval. Voyage AI's fine-tuning option allows customization for proprietary data.

  • Engineering lead reviewing AI PRs
    Pick: CodeBoarding

    CodeBoarding's branch comparison visual and PR review with architectural context helps you catch issues before merge. The GitHub Action ensures maps stay fresh in CI.
