FAQ
Yes, completely free — no trial period, no watermarks, no feature limits. We use them ourselves. The only cost is if you use AI features in the SEO app, which requires an Anthropic API key (free credits available on signup).
We built them for our own use. Sharing them free is a way to give back to the IT community and demonstrate the quality of work we do. If you find them useful and ever need a custom software solution, we'd love to talk.
No. Both apps run entirely on your computer. The SEO app calls the Anthropic API for AI features using your own key — nothing goes to Greatex servers. The email app connects directly to Zoho's SMTP servers using your credentials.
A Zoho App Password is a special password generated in your Zoho security settings that lets desktop apps access your email without exposing your main password. Go to accounts.zoho.in → Security → App Passwords → Generate New.
GEO (Generative Engine Optimisation) is the practice of optimising your website to be cited and recommended by AI tools like ChatGPT, Perplexity, and Gemini. As AI search grows, getting cited in AI responses is becoming as important as ranking on Google.
