The short version

  • Only Perplexity has a free tier, so it costs nothing to try first.
  • Each has a real cost: Perplexity context window has been stealthily reduced despite prior claims of 1-million-token capacity; Writer pricing is not publicly disclosed and requires a sales conversation, unlike consumer AI writing tools.
  • They diverge on capability: Perplexity covers Real-time web search, Writer covers Palmyra LLMs.

Where each one falls short

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

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

Writer

  • Pricing is not publicly disclosed and requires a sales conversation, unlike consumer AI writing tools.
  • Its proprietary Palmyra models are less widely benchmarked and documented than general-purpose models like GPT or Claude.
  • Primarily positioned for large enterprises, making it less accessible or cost-effective for individuals and small teams.
