An AI agent is a software system that completes a task on its own — it decides, acts and uses your tools instead of just producing text. OsAI builds these agents and automations for SMBs in the Stuttgart region: connected to your systems, tested in staging, operated after launch.
From mail triage to workflow automation with n8n to a knowledge assistant on your own data — built in an implementation sprint from €3,900 fixed price, operated as AI Partner from €390 a month.
An AI agent is a software system that pursues a goal on its own: it takes a trigger, makes decisions based on language models, calls tools and interfaces (mail, CRM, database, calendar) and delivers a result — without a human kicking off every step. The difference from a simple chatbot: a chatbot answers, an agent acts. The difference from rigid automation (a fixed n8n flow, say): an agent decides on the fly what step makes sense next. In practice OsAI combines both — reliable automation pipelines for the predictable, agentic decisions for the unpredictable — and builds both so that you check the result, not every click.
In short: a chatbot answers. An AI agent gets the task done — and hands you just the result.
Three facts that frame the picture.
In 2026 AI agents have gone from experiment to tool. The automation toolkit n8n alone is searched around 110,000 times per month on average in Germany (Google search volume, 12-month average, September 2025 to August 2026). The technology is mature and affordable — the bottleneck is no longer the tool, but the right first use-case.
Since its founding in May 2026, OsAI has built 21 website drafts for businesses and 14 of its own applications — live ones include Roast My Website, Angebots-Blitz and Projekt-Akte. The agency itself runs on a multi-agent system with 8 specialised roles around the clock. Built proof, not theory.
An AI agent starts at OsAI with the AI quick-check for €490 (one assessed use-case). The full build runs as an implementation sprint from €3,900 fixed price, ongoing operation via the AI Partner retainer from €390 per month. Typical delivery in 1–3 weeks.
No mixed bag — these are the systems that most often give SMBs the biggest lever.
Recurring processes run on their own: sync data between tools, generate reports, prepare invoices. Built with n8n, Make or straight code — you just check the result.
An agent trained on your content answers first inquiries over web, WhatsApp or mail around the clock — and escalates cleanly to you when it needs to get human.
Qualify inquiries, prepare quotes, coordinate appointments. The agent pre-fills, you decide — instead of chewing through every inquiry by hand.
An assistant that knows every file, mail and decision in your business and answers on demand — with the source. No more digging through folders and inboxes.
Voice-driven agents for phone and inbound: capture the request, classify it, route it. A channel almost no one in the SMB space owns.
Onboarding, approvals, status updates, HR routines: agents that take over the invisible admin work that eats hours every day.
This agency is operated by a multi-agent system with eight specialised roles, building websites, automations and content around the clock — steered from a custom command centre. We build AI agents because we work with them every day.
See real systemsThree phases, fixed price. You start where it fits and decide again after each phase.
We find the process with the biggest lever, clarify which data and tools are needed, and set a fixed price. Result: a concrete agent plan instead of buzzwords.
We build the agent, connect it to your tools (mail, CRM, Sheets, n8n), test in staging and go live. You see progress along the way, not just the final result.
After launch OsAI stays your partner: monitoring, fixes, monthly tuning. The agent grows with your business — as an AI Partner retainer.
Honestly: not every process needs an agent. If a simple automation is enough or AI isn't worth it yet, OsAI says so — before you invest.
The questions that come up most in the intro call.
At OsAI, a fully built AI agent comes out of an implementation sprint from €3,900 fixed price, in 1–3 weeks. Ongoing operation — monitoring, fixes, monthly tuning — costs from €390 a month as AI Partner. If you first want to check whether an agent is worth it, start with the AI quick-check for €490, which assesses one concrete use-case.
A chatbot answers questions, an AI agent gets tasks done. An AI chatbot for businesses gives information on your website, over WhatsApp or by mail and takes in enquiries. An AI agent goes further: it uses your tools such as mail, CRM or calendar, makes decisions and completes a task from start to finish — you just check the result. Often the chatbot is the visible part, and behind it an agent does the actual work.
Only what the specific use-case needs, and GDPR-compliant. Which data and tools are required is set transparently in the briefing, before anything is built.
Whatever is most robust. For clear, recurring processes often n8n; where decisions and flexibility are needed, agentic logic in code. OsAI isn't tied to a single tool.
Dates for the quick-check and workshop are arranged individually. An implementation sprint takes 1–3 weeks — no open-end, with a clear definition-of-done.
15 minutes, no obligation. We look together at where an AI agent gives you the biggest lever.
