Conversational agents for Messenger, WhatsApp, Telegram, web and email; multi-agent systems; voice AI; RAG knowledge assistants; and full business-process automation — all self-hosted on n8n + Docker if you prefer.

Can you build any kind of software?

Yes — web apps, SaaS, dashboards, CRM/ERP and internal tools, APIs, integrations, LMS and e-commerce platforms, with AI layered in where it adds value.

A focused automation or website can take 1–3 weeks. Custom software typically takes 4–12 weeks depending on scope. You get a clear timeline after the discovery call.
