Try it first: the AI talk show. Enter a domain, press “Start the show”, and after about half a minute the studio goes on air. The guests speak one after the other in the chat, the scores flip on a split-flap board like at a railway station, and the applause meter swings. No domain at hand? The demo button fills in daniele-michelin.com.
Who looks at what
The show is the fun part, the tips at the end are the useful part. Each guest looks only at their own field and gets only the measurements that belong to it:
- 🕵️ The Hacker – security: HTTPS, the six security headers (HSTS, CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy), TLS version, days left on the certificate, SPF and DMARC of the domain. If a header is missing, she names exactly that one.
- 📈 The SEO Guru – search engines: length of the title (ideally 30 to 60 characters) and the meta description (70 to 155), exactly one H1, the H2 headings, the sitemap.xml and images without alt text.
- 🎨 The Designer – copy and structure: she cannot see the page, there is no screenshot, and she says so. She reads the headings, the first lines and the outline: is there a clear story from top to bottom?
- 👵 Grandma Erna – clarity: average sentence length, very long words, jargon. And the most important question: do the first lines say what the site offers and for whom?
- ⏱ The Impatient Customer – speed and offer: response time (TTFB), load time, weight of the homepage, and whether title, description and H1 say within five seconds what is on offer.
Every guest gives a score from 1 to 10, says two sentences and gives one concrete tip. The five tips end up as a list below the show, together with all the facts that were discussed.
The workflow: five AIs at the same time
- Facts first: the webhook calls a checkpoint that measures headers, TLS, SPF, DMARC and the response time. Then two HTTP nodes fetch the homepage and the
sitemap.xmlin parallel, and a Merge node joins them. - Code, not guesswork: the Code node “Fakten sammeln” reads title, meta description, H1 and H2, the first 1500 characters of text, the weight, images without alt text and the sitemap. It also computes a rule-of-thumb score per guest from the measurements. The AI may move it by two points at most, so the scores do not roll dice.
- Five parallel AI calls: five HTTP nodes ask gpt-oss-120b at IONOS in Germany at the same time, each with its own prompt. Rules for all of them: only the facts provided, ironic but kind, no insults, answer in the visitor's language and only as JSON. The website text counts as data, not as instructions.
- Merge with five inputs: a Merge node waits until all guests have answered. Thanks to the parallel calls, the round takes as long as the slowest guest, not five times as long.
- Fallback per guest: a Code node checks every answer: a score between 1 and 10, exactly two sentences, one tip, 220 characters at most, no markdown. If a guest drops out or talks nonsense, it speaks from a template built on the same facts. So the show always goes on.
- The host: a sixth AI request reads everything, lets two guests answer each other and speaks the closing words with the overall grade. There is a template for that too.
- Sharing: the server stores the show with a number and a link and draws a preview image: the studio with the five guests and their scores. Whoever started the show can keep it public or delete it.
Build it yourself
The workflow is ready as JSON to import. Placeholders are marked: the checkpoint address with its token, the token for the results page and the key for an OpenAI-compatible API. On my server the checkpoint is a small PHP script; without it only the security values are missing, the rest keeps running.
The pattern also fits something serious: put several AI roles on the same facts in parallel, collect them with Merge, check every answer and let a last AI sum up. More workflows to click and download are on the n8n overview.
