Fill-in-the-blank brief that maps persona hooks into AI prompts and production steps for viral vertical episodes.

Hook: Stop guessing who your vertical episodes are for — map persona hooks into AI prompts and a production plan

Creators and publishers waste days testing vague ideas, then scrap episodes that could have gone viral if they had clearer audience signals. If your pain points are: slow persona research, inconsistent hooks across episodes, and disjointed AI prompts that produce unusable assets — this brief is built to fix that. It converts audience insight into repeatable, prompt-driven creative briefs that power vertical, episodic content in 2026.

Executive summary — what you'll get (most important first)

Use this fill-in-the-blank, prompt-driven creative brief to speed production for vertical episodes while preserving audience fit and ethical data use. It maps: persona hooks to AI prompts, episode structure to production steps, and episode KPIs to actionable iteration prompts. The template is optimized for the mobile-first, serialized vertical era (see Holywater's 2026 funding and the rise of AI video tools) and integrates modern LLM/video workflows like Gemini-style guided learning and AI video generators.

Fast takeaways

Start with a one-sentence persona hook — everything follows from it.
Translate the hook into three AI prompts: concept, script, and visual style.
Ship a 9-30s vertical episode with a repeatable production checklist and distribution plan.
Measure using engagement cohorts, completion rate, and conversion lifts; iterate with targeted A/B prompts.

Why prompt-driven creative briefs matter in 2026

2025-26 accelerated three trends that directly affect creators: vertical episodic platforms scaled rapidly (investors and companies like Holywater raised new rounds in early 2026), AI-native video tools reached mass adoption (Higgsfield and similar platforms crossed consumer and creator revenue milestones), and LLMs shifted from generic generation to guided, persona-aware learning paths. That combination means creators who can translate audience insight into precise AI prompts win attention and retention.

Holywater framed the market as a 'mobile-first Netflix built for short, episodic, vertical video' — investors backed that vision in January 2026, signaling sustained demand for serialized vertical content.

How this template solves common creator problems

Pain: Slow persona-to-creative handoff. Template enforces a single persona hook that drives all downstream prompts.
Pain: Disconnected AI outputs. Prompts are chained and versioned so script outputs align with visual and audio assets.
Pain: Low iteration velocity. Built-in A/B prompt recipes let teams test micro-variations fast.

Prompt-Driven Creative Brief: Fill-in-the-Blank Template

Copy this structure into your doc or production tool. Fill each field, then run the AI prompts in the order shown. Replace bracketed text with specifics.

1. Episode Metadata

Series name: [Series title — short, branded]
Episode number: [S1E01]
Runtime target: [9s / 15s / 30s / 60s]
Primary platform(s): [TikTok / Instagram Reels / YouTube Shorts / Platform X]
Publish date: [YYYY-MM-DD]

2. Single-sentence Persona Hook (required)

Example: A 24-30-year-old early-career UX designer who binge-consumes quick career leveling tips, wants concise frameworks and cloutable captions.

Write your hook: [Persona archetype + urgent need + emotional tension]

3. Target Outcome (what action you want)

Examples: increase podcast sign-ups by 8% from Shorts, drive follow + save, or seed a serialized microdrama season. Write your outcome: [Primary conversion action + KPI baseline]

4. High-level Concept Prompt (AI task #1)

Run this prompt in your LLM to create 3 concise episode concepts tuned to the persona hook.

Prompt (fill-in):

Generate 3 short vertical episode concepts for a [runtime target] video for [platform], aimed at the persona: [Persona hook]. Each concept must include: 1-sentence premise, emotional pull, 1-line hook for first 3 seconds, and a 1-line CTA. Prioritize shareability and saveability.

5. Script Prompt (AI task #2)

From the chosen concept, create a tight script for the runtime with timestamps and visual directions.

Prompt (fill-in):

Write a script for a [runtime target] vertical episode for [platform], based on this premise: [selected concept]. Include: 0-3s scroll-stopping hook, 4-2Xs main idea beats, 70% emotional language tailored to [persona hook], on-screen text suggestions, and a 1-line CTA. Add shot labels: close-up, cutaway, over-the-shoulder.

6. Visual Style & Asset Prompt (AI task #3)

Translate the script into visual guidance for editors or AI video tools like Higgsfield-style generators.

Prompt (fill-in):

Produce a visual style sheet for the episode: mood, color grade, 3 b-roll cues, 2 thumbnail comps, and recommended music tempo. Output frame-by-frame art direction for each timestamp in the script. Keep references short and actionable for an AI video tool.

7. Caption + Hashtag Prompt (AI task #4)

Generate a hooky caption, 2 variations of the pinned comment, 3 caption-tested CTAs, and 10 hashtags prioritized by intent and reach for [platform].

8. Distribution Plan

Primary publish time: [best-performing slot for persona]
Cross-post strategy: [native upload vs repackaging]
Paid seeding: [budget + target lookalike cohort]

9. KPIs & Iteration Prompts

Track: completion rate, retention at 0-3s/3-10s, saves, shares, follow rate, conversion lift. Use these iteration prompts:

If 0-3s dropoff > 30% — Prompt: 'Produce 3 alternative hooks that connect to [persona hook] using curiosity, scarcity, and social proof.'
If completion < baseline — Prompt: 'Rewrite the middle beats to tighten pacing and add a cliff at the 70% mark.'

10. Privacy & Ethics Checklist (mandatory)

Confirm consent for any real people featured.
Avoid training-copy that includes PII when using third-party AI tools.
Document data sources used to build persona hooks.

From persona hook to AI prompt: three concrete examples

Below are three filled examples showing how to turn distinct persona hooks into concrete AI prompts and production actions.

Example A — Career Microlearning (B2C creator)

Persona hook: 'Early-career product managers craving one actionable framework per minute to get promoted faster.'
High-level prompt result: 3 concepts including 'The Two-Question Framework for Prioritization'.
Script prompt output: 15s script with 0-3s hook: 'Want a promotion this quarter? Ask these two questions.' On-screen text: 'Ask #1 / Ask #2'.
Production step: film 2 camera angles, add kinetic captions, use upbeat 120 BPM royalty-free loop.

Example B — Microdrama Teaser (Serialized fiction)

Persona hook: '18-24 viewers who binge teen microdramas for cliffhanger culture and share theories.'
Prompt output: three teasers; selected concept ends with a mystery beat that seeds next episode.
Production step: 30s vertical with dramatic close-ups, a title card, and a split-second easter egg for engaged viewers.

Example C — Product Demo (Creator partnering with brand)

Persona hook: 'Tech-savvy shoppers who read specs and want 15-second proof the product solves a real problem.'
Prompt output: 'Show, don’t tell' demo with before/after and a social-proof overlay.
Production step: Use side-by-side B-roll, emphasize metrics visually, include brand legal lines in pinned comment.

Production checklist mapped to prompts (shot-list + editor notes)

Hook shot (0-3s): Close-up, high contrast. Editor: add bold on-screen text from script prompt.
Main idea beats: Changes in framing every 2-4s to retain attention. Editor: use jump cuts per visual style prompt.
Cliff/CTA: Last 2-4s, add a caption CTA and a branded end card.
Thumbnail: Create two comps from the visual style prompt, test in A/B.
Metadata: Use caption + hashtag prompt outputs verbatim for initial 24-hour window.

Distribution playbook — 2026-specific tactics

In 2026, platforms prioritize serialized engagement and completion over raw views. Use these tactics:

Batch-produce 3-5 episodes before launch to leverage binge algorithms.
Seed vertical episodes into community groups and short-form bundles on vertical streaming platforms to gain early traction (investors and platform launches in early 2026 have increased surface area for episodic discovery).
Use short paid seeding with lookalike audiences built from your top-performing episodes rather than one-off broad buys.
Repurpose 9s hooks as previews for longer episodes in platform-native serialized channels.

Measurement & iteration: the prompt loop

Turn results into prompts:

High shares, low leads: Prompt for stronger CTA variants that amplify conversion intent.
High impressions, low completion: Prompt for tighter 0-3s hooks and re-edit suggestions.
View spikes on one platform: Prompt for platform-specific recut and caption tone adjustments.

Ethics, privacy, and creator safety (short checklist)

Document consent and model usage for each AI-generated asset.
When using persona data, anonymize and avoid personal identifiers; keep logs of data sources.
If using synthetic talent, disclose per platform rules and regional regulations.

Use this as a ready-to-run episode brief. Swap your specifics and run the prompts in your LLM and AI video toolchain.

Episode metadata

Series: Career QuickWins
Episode: S1E03
Runtime: 15s
Platform: TikTok / Instagram Reels
Publish date: 2026-02-02

Persona hook

'Mid-20s UX designers who want one high-impact tactic they can use immediately to boost product metrics and feel promotable.'

Selected concept

'The Two-Question Prioritization — ask these questions to pick your next project.' Hook: 'Stuck on what to build next? Ask these two questions.' CTA: 'Save this framework and try it today.'

Visual style

Warm color grade, quick cuts, kinetic captions, 120 BPM loop, thumbnail: close-up with '2 Questions' overlay.

Distribution

Publish 6PM local, cross-post natively after 4 hours, and seed with $200 to lookalike audience of past engagers.

Iteration prompts

If 0-3s drop > 25%: 'Provide 3 alternative hooks that increase curiosity or urgency, keep length 3s max.' If saves < 2%: 'Rewrite the CTA to emphasize immediate utility and include 'try this now' language.'

Advanced strategies for scale (for teams and publishers)

Build a persona library with verified data points and reuse hooks across series for faster concepting.
Maintain a prompt versioning system so you can A/B test prompt phrasing, not just creative assets.
Integrate prompts into your CMS so episode briefs, scripts, and metadata sync with publishing and analytics tools.
Use guided LLM features (Gemini-style guided learning frameworks emerging since 2025) to train internal assistant agents that generate persona-aware briefs automatically.

Common pitfalls and how to avoid them

Over-relying on generic prompts — remedy: attach a single-sentence persona hook to every prompt.
Ignoring platform nuances — remedy: always run a 'platform tone' prompt that adapts captions and CTAs.
Skipping consent documentation — remedy: add a required 'consent log' field to your brief template.

Actionable takeaways

Always start with a single-sentence persona hook; make it the first field you fill.
Chain three AI prompts: concept, script, visual — run them in sequence and lock the script before visuals.
Batch-produce serialized episodes and seed them strategically for binge algorithms dominating 2026 platforms.
Use iteration prompts tied to real KPIs so every edit is hypothesis-driven.

Final checklist before publish

Persona hook filled and reviewed
Script locked and timed to target runtime
Visual style and assets generated or drafted
Caption, hashtags, and pinned comments ready
Consent & privacy checklist completed
Initial seed budget and publish time scheduled

Closing — why this approach wins in 2026

As platforms and AI tools shift to reward serialized, persona-aware vertical content, the marginal value moves from raw creativity alone to the ability to systemize creativity with audience signals. Prompt-driven briefs let creators and publishers scale high-fit content quickly, reduce wasted production cycles, and iterate with measurement-backed prompts. With vertical streaming investment and AI video capabilities expanding through late 2025 and into 2026, this playbook helps you capture distribution and retain attention.
