The Hidden Cost of "Free With Signup"

Creating an account for a grammar checker gives the service:

• Your email — expect promotional emails and "upgrade" reminders weekly
• Every piece of text you check — logged, analyzed, potentially used for AI training
• Your writing patterns — common mistakes, vocabulary level, writing style profiled
• Browser extension access — if installed, they read everything you type anywhere

A browser-based tool with no signup collects none of this. No email to spam. No text to store. No profile to sell.

Use Cases Where No-Signup Matters Most

• Confidential work emails — check grammar without sending company business through a third-party cloud
• Legal documents — fix typos without exposing privileged content to external servers
• Medical notes — HIPAA concerns make cloud-based text processing risky
• Job applications — fix your cover letter without creating yet another account
• One-time checks — you're not a "user" of this tool, you're fixing one email. No account needed.
