FAQ
Quick answers
What does OsAI do?
OsAI is an AI agency and web design studio based in Fellbach near Stuttgart, Germany. OsAI automates workflows in small businesses with AI, builds websites and custom web apps, and trains teams under the EU AI Act. Founded in 2026 by Osman Öztopcu.
Where do I start with AI in my business?
With a single workflow that regularly costs time today. OsAI's AI quick-check assesses one use case for effort, benefit and feasibility. That can turn into an AI agent that, for example, pre-sorts enquiries, and you only approve.
How much does AI automation cost?
It mainly depends on how many programs are connected, how clean the data is and how many exceptions there are. You get your fixed price after the free 15-min intro call, before any work starts. You agree with OsAI beforehand when the first result will be ready.
How much does a website cost?
It depends on the scope, for example the number of pages and whether copy and photos already exist. You see the draft before you place an order, and you get the fixed price before any work starts. The starting price is on the websites page.
Do I have to train my staff on AI?
Yes, if your business uses AI systems such as ChatGPT or Copilot. Since 2 February 2025, Article 4 of the EU AI Act has required measures for your team's AI literacy. Since 27 July 2026 a simplified version applies, with no required level or certificate. OsAI trains your team in half a day – up to 10 people, with a certificate of attendance for each person.
Who does OsAI work for – and where?
Small businesses: trades and construction, hospitality, real estate and service providers. On site in Stuttgart and the surrounding districts, across Germany via video.
How does working together work?
You request a draft or talk to Osman for 15 minutes. You then get a fixed price before any work begins. Building starts only once the draft fits – followed by the handover.
