Grammarly is the most widely used writing assistant in the world, installed on over 30 million browsers. It checks grammar, suggests style improvements, detects tone, and now generates text through GrammarlyGO. Its value is in ubiquity — it works inside Gmail, Google Docs, Slack, LinkedIn, and virtually every text field on the web.
Always-On vs. On-Demand
Grammarly’s extension runs in the background, catching errors as you type across every website and app. Txtory is an on-demand tool — you visit the page, paste your text, get help, and leave. The always-on approach catches mistakes you would not think to check. The on-demand approach gives you focused, intensive help when you specifically need it.
The Ecosystem Advantage
Grammarly has built an ecosystem: browser extension, desktop app, mobile keyboard, Google Docs plugin, Microsoft Office integration. That ecosystem is its moat — once you are using Grammarly everywhere, switching costs are real. Txtory has no ecosystem. It is a single web page. That is both its limitation and its freedom — nothing to install, nothing to uninstall, no data shared across platforms.
The Bottom Line
Grammarly is the right choice for writers who want always-on error detection and style suggestions across every platform. Txtory is the right choice for writers who want focused AI writing help on demand, for free, with no commitments.
