Contextly – Echtzeit-Chat mit YouTube-Videos 🎬💬
Die meisten KI-Erweiterungen beschränken sich auf Zusammenfassungen. Contextly geht noch einen Schritt weiter: Chatten Sie direkt mit jedem YouTube-Video. Stellen Sie präzise Fragen, vertiefen Sie sich in bestimmte Momente und erhalten Sie Antworten in Echtzeit – dank KI, die den Videoinhalt vollständig versteht.
Neue Funktionen:
🗝🗝🗝 Eigenen Schlüssel verwenden (BYOK) – Mehr Datenschutz und Kontrolle für Contextly-Nutzer
Mit der neuen Funktion „Eigenen Schlüssel verwenden“ (BYOK) in Contextly haben Nutzer die volle Kontrolle über die Verwaltung ihrer Daten und KI-Interaktionen. Verbinden Sie Ihren eigenen OpenAI-API-Schlüssel direkt mit Contextly und nutzen Sie so die intelligenten Funktionen des Tools optimal, während Sie gleichzeitig die volle Kontrolle und Transparenz über Ihre Nutzung behalten.
Mit Ihrem eigenen API-Schlüssel bestimmen Sie, wie Tokens verwendet werden, welche Modellversionen zum Einsatz kommen und wie Daten durch Ihr persönliches OpenAI-Konto fließen. Ihre Interaktionen werden nicht über die gemeinsame Infrastruktur von Contextly verarbeitet – alles bleibt an Ihre eigenen Zugangsdaten gebunden. Ob Sie GPT-5 für Forschung, Schreiben, Programmieren oder Brainstorming nutzen: BYOK gewährleistet, dass Ihre Daten privat bleiben und Ihre Benutzererfahrung flexibel und auf Ihre Arbeitsabläufe abgestimmt ist.
Die Einrichtung ist kinderleicht: Öffnen Sie einfach die Einstellungen, fügen Sie Ihren API-Schlüssel einmalig ein, und Contextly kümmert sich um den Rest. Ab diesem Zeitpunkt werden alle Antworten, Zusammenfassungen und Analysen sicher über Ihren Schlüssel generiert – ohne Kompromisse bei Geschwindigkeit, Zuverlässigkeit oder Qualität.
BYOK richtet sich an professionelle Anwender, Entwickler und datenschutzbewusste Nutzer, die das volle Potenzial von Contextly ausschöpfen und gleichzeitig die volle Kontrolle über ihre KI-Nutzung behalten möchten. Ihre Daten, Ihre Regeln – jetzt vollständig unterstützt von Contextly.
Unterstützte KI für BYOK: ChatGPT, Gemini und Claude. Weitere Anbieter folgen in Kürze.

- Jean Bravo
- Contextly has become my go-to extension for YouTube. As someone who watches a lot of tutorials and lectures, the AI summaries save me so much time. I especially appreciate the Bring Your Own Key option because it lets me use my own OpenAI API while keeping my data private. The chat feature works smoothly right inside the player, and asking questions about long videos feels like having a study buddy on demand. It is not perfect, the interface can feel a bit cluttered at first, but the time it saves makes it totally worth it. Highly recommend for students or anyone who learns from YouTube.

The ability to navigate YouTube content with real-time AI chat and support for over 120 languages makes it an incredibly useful extension for a global audience.

- ok
- Beatrice Melo
- Very convenient; the automatic summary dialogue saves me a lot of time, especially for long videos.
- David Schulte
- Very suspicious extension. The author mails random extension store developers and ask for 5 star reviews. I looked at the source and it is a vibe coded mess. All it does is taking the YouTube generated transcript and chapter overview into a Vercel Api builds a chat bot around it. The code mentioned a expensive subscription service with Standard, Premium and Unlimited models (https://contextlyapp.com/payments). The page is also not working and vibe coded. Again you can do this free in ChatGPT.
- Arcus Fargin
- If you're a student, researcher, or just hate spoilers, grab this now. 10/10 recommend!
