Final Recommendation

Neither tool's free tier details are extensively documented here, so you'll want to check their respective pages for token limits or feature restrictions that might affect your usage.

Merlin's strength lies in its versatility—it brings AI assistance to any website you visit, functioning as a sidebar that eliminates tab-switching and supports multiple AI models beyond just ChatGPT. This makes it ideal for researchers, marketers, and anyone who needs AI help while browsing. EditGPT, by contrast, excels at its specialized purpose: writers using ChatGPT directly benefit from its integrated proofreading and tone-refinement features, which provide real-time feedback without context-switching.

Pick Merlin if you want a general-purpose AI companion for web browsing across multiple sites and tasks. Choose editGPT if you primarily work within ChatGPT for content creation and want professional editing feedback without leaving the conversation. Your choice ultimately depends on whether you need broad AI assistance across the web or focused writing refinement in one tool.
