Custom Development

How does CoSy-Tec develop custom AI integrations for businesses?

CoSy-Tec develops custom apps and AI integrations for business processes that no standard tool covers. The process starts with a requirements analysis: which tasks should be automated, which systems need to be connected, which AI model fits?

Typical projects include document analyses, process automations with AI agents, internal knowledge bases (RAG) and API integrations to Bexio, CRM or ERP. The infrastructure runs at CoSy-Tec — no own server required at the customer.

Document Analysis

Contracts, quotes, emails — AI reads, checks and summarises.

Process Automation

Recurring tasks delegated to AI agents with tool use.

Internal Knowledge Base

Company knowledge as a RAG system — questions directly to your documents.

API Integration

Connection to Bexio, CRM, ERP or own systems via API.
