The short version

  • Only Perplexity has a free tier, so it costs nothing to try first.
  • Each has a real cost: ADP no pricing is published; every quote is custom and driven by employee count and which services are taken; Perplexity context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • They diverge on capability: ADP covers Payroll, Perplexity covers Real-time web search.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ADP

  • No pricing is published; every quote is custom and driven by employee count and which services are taken
  • Split into three separate products by company size, RUN for 1 to 49 employees, Workforce Now for 50 and above, and Lyric HCM for enterprise, so growing across a threshold means changing product rather than plan

Perplexity

  • Context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
  • Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
  • Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
  • Pro subscription quotas and feature access quietly reduced without user notification
