⚙️ Step 1 — Generate Viral Ideas with ChatGPT or Gemini

Start by finding trending video topics using ChatGPT or Google Gemini.

Prompt example:
Give me 10 viral short video ideas about psychology that attract high engagement.

Tip: Focus on themes like motivation, psychology, relationships, money, or productivity. These niches always perform well.

Alternative Tools:

• Google Trends – to spot what people search now.
• AnswerThePublic – to find popular questions.

🧰 Step 2 — Turn the Idea into a Script

Once you have your topic, use ChatGPT to write the full video script.

Prompt example:
Write a 45-second viral script about why people lose motivation easily, in a dramatic and emotional tone.

AI will generate a ready-to-use text you can later transform into voice and visuals.
