AI Act transparency duties (Article 50)

Since August 2, 2026 people must be told when they talk to an AI, and AI-generated content must be marked; this covers most business uses of AI.

Article 50 applies from August 2, 2026 and was not postponed by the 2026 AI Omnibus. A chatbot or voice agent must disclose that it is AI unless that is obvious. Providers of generative systems must mark output in a machine-readable way; systems already on the market got until December 2, 2026. Deployers must disclose deepfakes and AI-generated text published to inform the public, unless a person reviewed it and took editorial responsibility. A voluntary code of practice on marking and labeling was finalized in 2026, and breaches can cost up to €15 million or 3% of global turnover.

“a true bias for action” client CTO, public LinkedIn recommendation

Confidential by default. NDA is standard. I never show your project, name or screenshots without written consent, which is why this site names no clients without permission.
Your code, your accounts. Code and data stay in your repository and accounts. AI tools run with training on your data turned off, and secrets never reach a model.
A handover you can use. Every project ends with the same checklist: a README that gets it running, one architecture diagram, written decisions, CI, a runbook and a recorded walkthrough. It is done when someone outside the project can run it from the docs.
Boring technology where it counts. I pick a stack you can hire for. Anything experimental needs your yes and an exit plan.
Approach matched to your risk appetite. Prototype, product or regulated: the level decides how much autonomy the agents get and how much review and validation each change needs.
Everything checkable. Every number on my pages links to its source. My tools are free, and the idea validator skill is open source (MIT).

My pledge

Reply within 24 hours. I reply within 24 hours on working days, personally, not a bot. Weekend messages: by Monday noon.
Late means free. If I am late, the first hour of work is free. You do not have to ask.
Scope in writing within 24 hours. A free 30-minute call with no company deck, then the scope and the price in writing within 24 hours. You decide.
The person who does the work. You talk to the person who does the work. No sales layer, no handoff.
Follow-up only with news. I follow up only when I have something new for you. Never a "did you see my offer".
Honest "not a fit". If I am not the right person, I say so on the call and point you to someone who is.
