Common mistakes when choosing AI writing tools
Choosing by hype
The most talked-about tool is not always the best fit for your workflow.
Ignoring editing
AI writing still needs review, fact-checking, structure, and human judgment.
Overpaying too early
Many users should test a general-purpose tool before paying for a specialized writing platform.
Using one tool for everything
Research, drafting, editing, and publishing may need different workflows.
