Built this Chrome extension that generates professional emails using AI while keeping all data processing local to your browser. Unlike other AI email tools, EffiMail integrates directly with existing workflows (Salesforce, HubSpot, Gmail, Outlook) without sending sensitive data to external servers. Key features: Advanced prompt engineering for brand-consistent voice Enterprise-grade security with GDPR/CCPA compliance Built-in ROI tracking and A/B testing 500K+ active users saving 4+ hours per week The local processing approach solves the privacy concerns most companies have with AI tools, while the workflow integration addresses the friction that kills adoption in enterprise environments.

I built EffiMail (https://your-domain.com) to solve a problem I faced: finding quality email productivity resources in multiple languages. What it does: Comprehensive guides on email management, privacy, and productivity Free tools: template generator, spam checker, subject line analyzer, read-time calculator Available in 6 languages (EN, ZH, JA, DE, ES, FR) Mobile-optimized with fast search and categorization Tech stack: Next.js 15 with App Router Static generation for performance i18n with next-intl Tailwind CSS for responsive design MDX for content management Why I built it: Most email productivity content is English-only, limiting accessibility for global teams. I wanted to create a comprehensive resource that works across languages and cultures. The trickiest part was handling MDX content localization while maintaining SEO performance. I ended up with a file-based approach that generates static pages for each locale. Looking for feedback on: Performance and mobile UX Translation quality (used mix of professional and AI translation) Missing features or content gaps Technical architecture suggestions Happy to answer questions about the implementation or discuss email productivity challenges you've faced.
