Isaac vs Grammarly: Academic Research Workspace vs Grammar Checker
Grammarly helps you write correctly. Isaac helps you research and write.
Grammarly is an excellent grammar and style checker used by millions. However, it was designed for general writing across emails, social media, and business documents. Academic writing has fundamentally different needs.
Researchers need more than grammar correction. They need literature search, document analysis, citation management, and AI assistance that understands academic conventions. Isaac addresses all of these in one workspace.
Think of it this way: Grammarly polishes individual sentences. Isaac helps you build the entire paper, from finding sources to writing the final draft. They serve different purposes at different stages of the academic process.
