Grammarly vs Writesonic
A writing assistant that corrects and improves text you have already written, rather than generating content from a brief. Now an AI search visibility platform -- it tracks how brands appear in ChatGPT, Gemini and Google AI Overviews -- with article generation included rather than as the main product.

Grammarly
Strengths
- Genuinely useful free tier -- grammar, spelling and tone cost nothing
- Works everywhere you already write, rather than in its own editor
- Plagiarism and AI-detection included at $12, which the content generators charge far more for
- Cheapest paid tier of any tool in this category
Trade-offs
- It improves writing rather than producing it -- 2,000 prompts a month is not a content pipeline
- No brand voice depth compared with a dedicated marketing platform
- Suggestions can flatten distinctive prose toward a house style if accepted uncritically
Grammarly: who it suits
Buy it if
- Anyone who writes a lot and wants it to come out cleaner
- Teams enforcing a consistent style across many writers

Skip it if
- Producing content at volume from a brief -- Jasper or Copy.ai are the tools for that
- Anyone wanting an AI that drafts for them, since this is fundamentally an editor
- Writers who value a distinctive voice and would rather not be nudged toward the average
