AI writing assistants are tools that leverage natural language processing and generation to provide real-time assistance and support to human writers. AI writing assistants can help generate ideas, offer suggestions, improve grammar and style, provide feedback on structure and clarity, and offer relevant information or examples. These tools enhance the writer's creativity, productivity, and overall writing quality.

AI writing assistants are different from AI writer tools in terms of functionality. An AI writer tool focuses on generating content autonomously, whereas an AI writing assistants help writers improve their content. To be categorized as an AI writing assistant, a tool must:

  • Understand and interpret human-written text accurately, understanding the context, meaning, and nuances to provide relevant suggestions and insights.
  • Offer intelligent suggestions, grammar corrections, and improvements in sentence structure, adapting recommendations to match the specific style, tone, and purpose of the writing across different domains and genres.

How relevant, verifiable metrics drive AIMultiple’s rankings

AIMultiple uses relevant & verifiable metrics to evaluate vendors.

Metrics are selected based on typical enterprise procurement processes ensuring that market leaders, fast-growing challengers, feature-complete solutions and cost-effective solutions are ranked highly so they can be shortlisted.
Data regarding these metrics are collected from public sources as outlined in the “What are AIMultiple’s data sources?” section of this page.


There are 2 ways in which vendor metrics are processed to help prioritization:
1- Vendors are grouped within 4 metrics (customer satisfaction, market presence, growth and features) according to their performance in that metric.
2- Vendors that perform high in these metrics are ranked higher in the list.


The data used in each vendor’s ranking can be accessed by expanding the vendor’s row in the below list.
This page includes links to AIMultiple’s sponsors. Sponsored links are included in “Visit Website” buttons and ranked at the top of the list when results are sorted by “Sponsored”. Sponsors have no say over the ranking which is based on market data. Organic ranking can be seen by sorting by “AIMultiple” or other sorting approaches.
