Gemini Chatbot তৈরি করতে Gemini Api Key লাগবে তা নিচে বলে দিচ্ছি। Step-by-Setep ফলো করুন। তো চলুন শুরু করা যাক। |
প্রথমে এই লিংক এ ক্লিক করুন →
তারপর New Project তৈরি করুন।
Search “Gemini” and click..
Enable now
Click & Api key generate
Copy Api key
এই Api key টা শুধু Javascript কোড এর এখানে বসাবেন।
তো এখন কোড গুলে নিন।
