Instead of a $144 Grammarly renewal, he built his own with Replit and MCP in a day

Reshared by Replit founder Amjad Masad: upon getting a $144 Grammarly renewal notice, the author put that money into Replit credits and built his own tool.
- Within a day he had a working app, Content Refinery, covering Grammarly's core job plus customization around his actual writing/publishing workflow.
- The standout feature: hooking Ubersuggest's MCP server directly into the editor via Replit's built-in MCP integrations, so keyword research no longer lives in a separate tab — setup took seconds.
- His thesis: subscriptions mean living inside someone else's roadmap, and AI-assisted coding has cut the upfront cost of building your own enough to make it worth trying.
