Topic: "5 ChatGPT Prompts That Changed How I Code"

00:00 — HOOK

I tried 100 ChatGPT prompts last week. 95 were useless. But these 5? They cut my coding time in half. The first one alone saved me 4 hours yesterday — let me show you.

00:30 — INTRO

If you're a developer using ChatGPT for boilerplate or quick fixes, you're using maybe 10% of what it can actually do.

Frequently asked questions

Is the AI script generator really free?+

The idea generator is 100% free, no signup. Full scripts (3000+ words) are part of paid plans, but you can try one free script when you sign up.

How long are the scripts?+

Scripts are sized to your target video length. A 10-minute video typically generates a 1500-word script; a 15-minute video gets 2300+ words. We tested 50,000+ videos to calibrate the words-per-second ratio.

What AI models does it use?+

TubeSpark routes between GPT-4, Claude Sonnet 4.5, and Gemini 2.5 depending on the stage. The strategist uses one model, the writer uses another — no single-model bottleneck.

Will my scripts sound generic?+

No. The writer adapts to your channel's voice based on the audience and niche you select. Pro plans pull from your actual past videos to match your specific tone.

Can I edit the script before exporting?+

Yes. You can edit at any stage — outline, individual sections, or the final script. Export options include plain text, Markdown, or .docx.

What languages are supported?+

English, Portuguese (Brazil), Spanish, French, and Chinese (Simplified). The AI writes natively in each language with cultural adaptation, not literal translation.
