Include monthly search volume, competition level and first 30-day revenue estimate." 2️⃣SCRIPT + HOOK MACHINE "Write 30 viral short-form video scripts for [your niche]. Each script must have: attention-grabbing hook in first 1.5 seconds, storytelling arc, strong CTA, and exact voice-over text. Optimize for retention and algorithm." 3️⃣FREE VIDEO GENERATOR PROMPT "Create the perfect prompt for Kling AI / Runway Gen-3 / Luma Dream Machine (free tier) to generate a high-quality 8-second clip for this script: [paste script]. Include camera movements, lighting, style and negative prompt." 4️⃣THUMBNAIL ARCHITECT "Design 5 click-magnet YouTube thumbnail concepts for the video titled '[title]'. Describe exact layout, colors, text, facial expression and emotional trigger that will force clicks." 5️⃣VIRAL TITLE & DESCRIPTION "Generate 10 YouTube + TikTok titles + full SEO descriptions for the video script above. Include power words, numbers, emotional triggers and hashtag strategy for maximum reach." 6️⃣30-DAY CONTENT BLAST "Create a complete 30-day posting calendar using only free AI video tools. 1 Short per day. Include topic, hook, script number, posting time (best for my timezone) and growth hack for each day." 7️⃣MONETIZATION ACCELERATOR "I’m starting from zero.

Prompt 1 — Niche & Positioning "Analyze the top 10 YouTube niches with high CPM, low competition, and strong evergreen demand. For each, give me: average CPM, content difficulty, monetization paths beyond AdSense, and a 3-word channel concept." What this gives you: A data-backed niche decision instead of guessing. Prompt 2 — Channel Identity "I'm starting a YouTube channel about [NICHE]. Create a full channel identity: channel name (5 options), tagline, target audience persona, content pillars (4), and a 'unique mechanism' that differentiates me from existing creators." What this gives you: A brand, not just a channel. Prompt 3 — 90-Day Content Roadmap "Build a 90-day YouTube content calendar for a new channel in [NICHE]. Include: 12 video titles optimized for search, upload schedule, which videos to prioritize for SEO vs. virality, and a content progression that builds authority over time." What this gives you: A publishing plan that compounds over time. Prompt 4 — Video Script System "Write a full YouTube script for '[VIDEO TITLE]'. Use this structure: hook (first 30 seconds designed to stop scrolling), problem agitation, solution walkthrough, 3 key insights, CTA, and an end screen tease for the next video. Tone: [conversational/authoritative/etc.]" What this gives you: Scripts that retain viewers and drive watch time. Prompt 5 — SEO & Thumbnail Strategy "For the video '[TITLE]', give me: 3 thumbnail concepts with text overlay copy, a YouTube SEO-optimized title (under 60 chars), description (with timestamps, keywords, links), and 10 tags. Also suggest A/B test variations for the thumbnail." What this gives you: Click-through rate and discoverability baked in before you publish. Prompt 6 — Monetization Stack "I have a YouTube channel in [NICHE] with [X] subscribers. Build me a full monetization roadmap beyond AdSense: affiliate opportunities, digital product ideas, sponsorship pitch template, and a lead magnet I can offer to build an email list from my audience." What this gives you: Multiple income streams so you're not dependent on ad revenue. Prompt 7 — Growth & Repurposing Engine "Take this YouTube video script/transcript and repurpose it into: a Twitter/X thread, a LinkedIn post, 3 YouTube Shorts hooks, an email newsletter, and a Pinterest description. Also suggest which platforms to prioritize based on my niche." What this gives you: One video → 7+ pieces of content, multiplying your reach without extra work.
