Questions About TENSIX Services
How is a custom AI agent different from a ready-made AI tool?
A ready-made tool gives everyone the same features. A custom AI agent follows your own process, uses your own documents and data, and runs in accounts you own, so your data stays under your control. See AI agent development.
Why use n8n instead of Zapier?
n8n is an automation tool like Zapier that can run on your own server. It handles more complex steps and custom code, and self-hosting removes per-task fees, which usually makes it much cheaper as you grow.
What is the difference between SEO, AEO and GEO?
SEO helps your pages rank in normal Google results. AEO shapes your content so it can be shown as a direct answer. GEO helps AI tools like ChatGPT, Gemini and Perplexity understand your business and mention it. See AI search visibility.
Can your AI systems use OpenAI, Claude, Gemini or DeepSeek with our existing database?
Yes. We integrate the AI model that best fits your operations to your existing database, CRM or ERP through a secure layer with strict rules on what the AI can read and change.
Do you work on Shopify, WooCommerce or Magento stores?
Yes, for SEO and speed work. Our engineers implement structured schema markup, set up Google Shopping product feeds and fix page speed problems, so search engines understand your products better.
How do monthly retainers work?
Retainers start at ₹39,999 a month. The Growth Engine plan has no lock-in and can be paused or cancelled at the end of any 30-day cycle, and you work directly with our senior engineering team. See retainers and fractional CTO.
