Grammarly starts at $12/mo, while ChatGPT Plus starts at $20/mo. Consider not just the sticker price but the total cost of ownership — including the time you'll spend using each tool.
If you value your time at $50/hour and spend 5 hours/week on content creation, that's $1,000/month in time cost alone — regardless of which tool you choose.
Choose Grammarly if: You need proofreading and grammar and prefer grammar checking.
Choose ChatGPT Plus if: You need general ai assistance and ideation and value versatile ai.
Consider neither if: You want automated video content without ongoing manual effort. Both tools require continuous time investment.
