⚠️ Pitfall Guide

As a senior developer with 15+ years of experience, I must warn you: Mainstream Markdown editors contain serious performance traps and privacy risks that most users are unaware of.

Pitfall 1: AI Features Cannot Be Truly Disabled
Notion and Obsidian's AI features continue running in the background even after being "disabled," consuming 200-400MB of RAM for "silent indexing" operations that you never authorized.

Pitfall 2: Cloud Sync Privacy Risks
Your note content is sent to third-party servers for analysis. Even with "end-to-end encryption," metadata (file sizes, edit timestamps, IP addresses) remains fully exposed to the service provider.

Pitfall 3: Plugin Security Vulnerabilities
Obsidian's third-party plugins have full system access permissions. Multiple incidents have occurred where plugins exfiltrated user data, including sensitive personal and business information.

Pitfall 4: Subscription Traps
"Free" tiers typically limit you to 3-5 devices and bombard you with AI feature upgrade popups every 15-20 minutes, actively disrupting your writing flow and productivity.
