by: HookCraft Studio
HookCraft Studio turns a topic and source material into a complete, fact-checked faceless-YouTube package — not just a hook. You get: 10 scored titles (top 3 shown), a full script (900-1300 words) with a scroll-stopping hook grounded strictly in your source (no invented facts), a mandatory fact-check pass with a reproducible score, and 5 scored thumbnail-text concepts that don't just repeat the title. Built from a method proven on a live YouTube channel.

HookCraft Studio

A complete script-to-thumbnail package for faceless YouTube channels — built
from a method proven on a live channel, not a generic "write me a script" prompt.

What you get

Give it a topic, your source material, your niche/voice, and a target length.
It returns, in order:

  1. 10 scored titles — curiosity gap, specificity, honest click potential,
    and clarity scored 0-100 each. Top 3 shown first.
  2. A full script (labeled sections: HOOK, SETUP, PROBLEM, ESCALATION,
    DISCOVERY, DATA/EVIDENCE, 1300 words by
    default, written for voiceover — never markdown, never a generic
    "hey guys welcome back" op
  3. A mandatory fact-check pass, scored with a reproducible formula
    (not just an LLM's opinioniered against
    your source material and flagged if it can't be verified.
  4. **5 scored thumbnail-text xt (3-5 words)
    that complements the title instead of repeating it, ranked by a
    fixed length/overlap formu

What makes it different

  • **Grounded, not generative. script must
    come from the source text or URL you provide. If a data point isn't
    there, it gets flagged as `ented.
  • Honest about length. If your source material only supports a
    shorter script, it says so y-grounded
    script instead of padding it with filler to hit a word count.
  • **Scoring is reproducible.*ores come from
    fixed formulas (see scripts/fact_check_scorer.py and
    `scripts/thumbnail_scorer.pery time.

Who it's for

Solo creators, small teams, as YouTube
content (news, finance, true crime, AI/tech, gaming, etc.) who want the
whole title-to-thumbnail pack a script.
