47 mentions across 3 sources · 30% positive — critical

Hacker News, YouTube, Lemmy

What users praise

  • Expert workforce (doctors, lawyers, engineers) for nuanced feedback, widely respected.
  • Proprietary benchmarks like GDP.pdf and HANDBOOK.md are cited by major labs.
  • Strong backing from founder Edwin Chen, who scaled to $1BN+ revenue without funding.
