Την Κυριακή 21 Ιουνίου 2026, στις 18:30, συναντιόμαστε στο Gazi College Piraeus για ένα meetup αφιερωμένο στο Best Practices For AI Content Creators και στις νέες δεξιότητες που χρειάζονται οι content creators, copywriters, bloggers, marketers και digital professionals στην εποχή της Τεχνητής Νοημοσύνης. Όλες και όλοι μιλούν για AI content. Όμως το μεγάλο ερώτημα παραμένει: πώς δημιουργούμε περιεχόμενο με τη βοήθεια της Τεχνητής Νοημοσύνης χωρίς να χάνεται η ποιότητα, η αυθεντικότητα, η στρατηγική σκέψη και η ανθρώπινη φωνή μας; Ήρθε η ώρα να δούμε μαζί τι σημαίνει πραγματικά premium AI content. Όχι βιαστικά prompts. Όχι γενικά κείμενα που μοιάζουν μεταξύ τους. Όχι περιεχόμενο που απλώς γεμίζει σελίδες και feeds. Αλλά περιεχόμενο που έχει σκοπό, δομή, ακρίβεια, προσωπικότητα, SEO αξία, AI visibility και πραγματική χρησιμότητα για τον άνθρωπο που το διαβάζει. Στο meetup θα εξερευνήσουμε μαζί: * Πώς χρησιμοποιούμε το AI ως συνεργάτη σκέψης και όχι ως αυτόματο αντικαταστάτη. * Ποια είναι τα βασικά best practices για να δημιουργούμε premium AI-assisted content. * Πώς προστατεύουμε τη δική μας φωνή, εμπειρία και επαγγελματική ταυτότητα μέσα σε AI-generated περιεχόμενο. * Πώς συνδέονται το AI, το SEO, το AEO, το GEO και τα LLMs με τη νέα πραγματικότητα της ψηφιακής ορατότητας. * Πώς μπορούμε να κάνουμε ένα AI κείμενο πιο καθαρό, πιο αξιόπιστο, πιο ανθρώπινο και πιο χρήσιμο. * Ποια λάθη κάνουν συχνά οι creators όταν χρησιμοποιούν AI εργαλεία για blogs, newsletters, social media και websites. * Πώς χτίζουμε περιεχόμενο που μπορεί να διαβαστεί, να κατανοηθεί και να προταθεί τόσο από ανθρώπους όσο και από AI συστήματα. * Αν χρησιμοποιείς ήδη AI εργαλεία αλλά νιώθεις ότι το αποτέλεσμα χρειάζεται περισσότερη ποιότητα, προσωπικότητα και στρατηγική, αυτό το meetup είναι για σένα. * Αν θέλεις να καταλάβεις τι σημαίνουν στην πράξη όροι όπως AEO, GEO, LLM Optimization, AI Visibility και AI Agents για τη δουλειά σου, αυτό το meetup είναι για σένα. **Αν θέλεις να δημιουργείς περιεχόμενο που δεν ακούγεται πρόχειρο, γενικό ή άψυχο, αλλά έχει επαγγελματική αξία και ανθρώπινη παρουσία, τότε έλα στην παρέα μας.** * Ημερομηνία: Κυριακή 21 Ιουνίου 2026 * Ώρα: 18:30 * Τοποθεσία: Gazi College Piraeus * Θεματική: Best Practices For Premium AI Content * Γλώσσα: Ελληνικά * Δωρεάν συμμετοχή – κράτηση απαραίτητη! * Οι θέσεις είναι περιορισμένες – κράτησε τη δική σου εγκαίρως. Την συζήτηση θα συντονίσει η **Αρετή Βάσσου**, ιδρύτρια του **[IDEADECO SEO Copywriting Agency.](https://ideadeco.co/)** **Λίγα λόγια για εμάς:** Στον κύκλο των **Female Copywriters & Content Creators** δίνουμε χώρο και φωνή σε επαγγελματίες γυναίκες που δραστηριοποιούνται στους τομείς του digital marketing, SEO, AI, AEO, GEO, copywriting, blogging, content writing, web design, development, photography, podcasting και digital content creation. Έχουμε ήδη εκπαιδεύσει πάνω από **3.150 γυναίκες** σε όλα τα σύγχρονα εργαλεία του digital κόσμου, και συνεχίζουμε με έμπνευση, φροντίδα και ομαδικότητα. Σε περιμένουμε να μοιραστούμε εμπειρίες, απορίες και έμπνευση, πάντα με καφέ, φιλική διάθεση και ουσιαστικό επαγγελματικό networking! ***Όροι Χρήσης & Πολιτική Απορρήτου:*** *Με τη συμμετοχή σας αποδέχεστε τη χρήση, διατήρηση και επεξεργασία των απαραίτητων προσωπικών δεδομένων για την ομαλή λειτουργία του meetup (όνομα, επίθετο, email, τηλέφωνο, ιστοσελίδα, blog, social media).

Tired of dating apps or surface-level social events? This is different. Relational Labs is a guided connection experience for singles who want more honest, playful, emotionally intelligent interaction — without performance, pressure, or endless small talk. This is not speed dating. Not networking. Not “pitch yourself to strangers.” It’s a facilitated relational container rooted in psychology, emotional intelligence, attachment work, social dynamics, nervous system awareness, and real-world human connection — made practical enough that you can actually live it instead of reading another 50 books about it. ## What happens • A 2-hour guided online relational experience • Real-time connection exercises designed to create authentic interaction • A format that adapts in real time to whoever is present • Optional participant-led in-person continuation afterward • WhatsApp connection thread after the session ## This may be for you if: • You’re tired of shallow or repetitive social spaces • You want deeper connection without forced intimacy • You enjoy personal growth, psychology, communication, or relational work • You’re open to meeting people in a more intentional way ## Important This experience runs with whoever is present and takes its own shape each time. Sometimes expansive. Sometimes intimate. Both are the real thing. Booking happens through our website. 👉 Reserve your spot: [https://consciousconnectionsclub.com/join](https://consciousconnectionsclub.com/join) Optional in-person continuation: same day or within 48 hours depending on the city Most people come alone. People often leave surprised by how quickly strangers can feel human, warm, honest, and real. Sometimes awkwardness turns into ease. Sometimes curiosity turns into chemistry. Sometimes people simply remember what it feels like to actually connect again.

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
