Analyst summary
Grammarly
Grammarly has adapted its mature writing-assistance platform for AI with strong enterprise controls, HIPAA BAA support, and clear no-training commitments for Business customers. Long operating history and SOC 2/ISO 27001/27701 stack make it a low-risk choice for writing-assistance workflows.
A low-risk, mature choice for writing-assistance use cases on the Business or Enterprise tier.
Writer
Writer differentiates from other writing-assistance platforms by running its own in-house Palmyra LLM family instead of routing to OpenAI or Anthropic. This avoids third-party LLM provider risk and enables HIPAA BAA coverage and IP indemnification on enterprise plans. Models trail frontier labs on general benchmarks, but are purpose-built for enterprise writing.
A strong choice for enterprise content teams needing controlled, indemnified AI writing without third-party LLM exposure.
