Whether you’re a student, professional, or lifelong learner, Contextly helps you save time, understand faster, and learn smarter from any video. New Features: 🗝🗝🗝 Bring Your Own Key (BYOK) — Enhanced Privacy and Control for Contextly Users The new Bring Your Own Key (BYOK) feature in Contextly gives users complete control over how their data and AI interactions are managed. With BYOK, you can now connect your own OpenAI API key directly to Contextly, allowing you to take full advantage of the tool’s intelligent capabilities while maintaining full ownership and transparency over your usage. By using your own API key, you decide how tokens are consumed, what model versions are used, and how data flows through your personal OpenAI account. This means that none of your interactions are processed through Contextly’s shared infrastructure — everything remains tied to your own credentials. Whether you use GPT‑5 for research, writing, coding, or brainstorming, BYOK ensures your data stays private and your experience remains flexible and aligned with your workflows. Setting it up is straightforward: just open the settings panel, paste your API key once, and Contextly will handle the rest seamlessly. From that point on, all responses, summaries, and analyses are generated securely through your key, with no compromises on speed, reliability, or quality. BYOK is designed for professionals, developers, and privacy‑conscious users who want to unlock the full power of Contextly while keeping complete autonomy over their AI usage. It’s your data, your rules — now fully supported by Contextly. AI supported for BYOK: ChatGPT, Gemini and Claude.
