What real users say: Million vs Voyage AI

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Million

117 mentions across 8 sources · 46% positive — mixed (averaged across 8 sources)

Hacker News, YouTube, Product Hunt, App Store, Stack Overflow, GitHub, Lemmy, Tech Press

What users praise

  • • Strong founder credibility from React Scan and React Doctor projects.
  • • Mission directly addresses a real pain: verifying AI-generated code.
  • • Backed by Y Combinator and notable angels in the AI space.
  • • Open-source ethos likely to attract community contributions.

What frustrates them

  • • No public product, pricing, or documentation yet.
  • • Homepage is just a mission statement, lacking substance.
  • • GitHub issues show integration problems in related tools.
  • • Uncertain if ReactDoctor/ReactScan will be merged into Million.

Voyage AI

64 mentions across 6 sources · 54% positive — mixed (weighted across 6 sources)

Hacker News, YouTube, App Store, Stack Overflow, GitHub, Lemmy

What users praise

  • • Domain-tuned legal and finance embedders cut irrelevant docs by 25% in the Harvey case
  • • 3x-8x shorter vectors materially cut vectorDB storage and search costs
  • • rerank-2.5 instruction following lets you steer ranking behavior in plain language
  • • voyage-multimodal-3.5 handles images and text in a single retrieval pipeline

What frustrates them

  • • Default terms train on API customer data with a perpetual, irrevocable license grant
  • • Per-million-token pricing gets expensive fast for high-frequency agent RAG pipelines
  • • A small Jina model reportedly beat Voyage on retrieval in one public benchmark
  • • Open-source ecosystem still thin — Python library has only 114 GitHub stars
