What do real users say about Nos 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.

Nos

No verifiable community signal. We scanned public discussion on Aug 21, 2026 and found posts matching the name “Nos”, but could not establish that they are about this product rather than something else sharing its name. Rather than publish a score built on the wrong subject, we publish none.

Voyage AI

55 mentions across 5 sources · 53% positive — mixed (weighted across 5 sources)

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

What users praise

  • • Produces embeddings good enough that developers ship real RAG, search, and memory apps on it
  • • Domain-tuned legal and code models address the retrieval problems generic embedders struggle with
  • • Shorter vectors (3x-8x) cut vectorDB storage and search spend meaningfully in production
  • • Plugs into any vectorDB and any LLM, confirmed by builders wiring it into Qdrant and GoodMem

What frustrates them

  • • Default training on API customer data is a serious blocker for confidential workloads
  • • Lost a head-to-head embedding comparison to a smaller Jina model in one benchmark
  • • Python library has only ~114 GitHub stars, so community help and examples are limited
  • • Per-token billing with no subscription makes agent-driven spend hard to cap
