The Hook Tester is an AI-powered tool that generates and scores
opening lines (hooks) for your social media content. It tests
hooks against virtual audience personas to predict which ones
will grab attention and stop the scroll.

Click "Hook Tester" under Creator Pro in the sidebar, or
navigate to /creator-pro.

Choose the format you are creating hooks for:

  Video/Reel
    The first spoken or on-screen words of a short-form video.
    Viewers decide in 0.5-1.5 seconds whether to keep watching.

  Photo
    The first ~125 characters of an Instagram caption before
    the "more" cutoff. This is what appears in the feed.

  Text
    The opening line of a text-only post on X, Threads, or
    LinkedIn. No image to rely on -- the words do all the work.

  Email
    Subject line (~50 characters) plus preview text (~90
    characters). Tested as they would appear in an inbox scan.

1. Select your content format (Video, Photo, Text, or Email).

2. Enter your hooks (optional):
   Type one hook per line in the "Your Hooks" text area. These
   will be tested alongside AI-generated variations.

3. Describe your content (optional):
   If you want hooks generated from scratch, describe what your
   post or email is about. This gives the AI context.

4. Click "Generate & Test."

You need at least one input (your hooks or a content description)
to start.

The Hook Tester runs through 4 automated steps:

Step 1: Hook Generation
  AI creates 5-10 hook variations based on your input and brand
  voice. If you entered your own hooks, AI improves them and
  generates alternatives. All hooks (yours + AI) go to testing.

Step 2: Persona Building
  AI creates 5 distinct virtual audience personas relevant to
  your format. Each persona has a name, age, scroll style,
  relationship to your brand, and vulnerabilities.

Step 3: Evaluation (3 Rounds)
  Each of the 5 personas independently ranks ALL hooks from
  strongest to weakest across 3 separate rounds. They evaluate
  based on gap creation, reaction provocation, and authenticity.

Step 4: Score Aggregation
  Results from all rounds are combined into a final score and
  ranking for each hook.

You can click "Stop" at any time to cancel a running test.

Each hook receives:

  Score (10-88%)
    Higher is better. Calculated from average rank across all
    persona evaluations.

  Grade
    A+ (85-88%)  -- Exceptional
    A  (75-84%)  -- Excellent
    B  (60-74%)  -- Good
    C  (40-59%)  -- Average
    D  (10-39%)  -- Below average

  Rank
    Position among all tested hooks (#1 is best).

  Average Rank
    Mean position across all persona evaluations (e.g., 2.4/15).

  Evaluation Count
    How many evaluation rounds contributed to the score.

  Persona Notes
    Up to 4 unique observations from the virtual personas
    explaining why the hook works or does not.

Each hook is also tagged as "YOUR HOOK" or "AI" so you can see
how your ideas compare to AI-generated alternatives.

Save your best hooks to keep them for future comparison:

  - Click the save icon on any hook to add it to Saved Winners.
  - Saved hooks are automatically re-tested alongside new ones
    in future sessions.
  - Use "Clear All" to remove all saved winners.

Saved hooks display a "SAVED" badge.

  Save    -- Bookmark the hook for future testing sessions
  Copy    -- Copy the hook text to your clipboard
  Create Post (non-email formats only)
          -- Opens the Post Wizard with the hook pre-filled as
             the caption opening line. Post type, topic, and
             content description are also pre-filled.

After scores are generated, click "Re-Test" to run a new
evaluation on the same set of hooks. This can produce slightly
different results since persona rankings have natural variation.

After testing completes, expand the "Personas" section to see
the 5 virtual audience members who evaluated your hooks. Each
shows their name, age, scroll style, relationship to your brand,
and what they are vulnerable to.

Hook testing uses your AI generation credits. Check the Usage
page to see your remaining balance. If you are on a free or
lower tier, an upgrade prompt may appear.

- Test 3-5 of your own hooks alongside AI variations to see
  which approach performs best.
- A/B test different angles: try a question, a bold statement,
  and a curiosity gap on the same topic.
- Save your A+ and A hooks as winners so they are automatically
  included in future tests for comparison.
- Use "Create Post" directly from a winning hook to start
  building content around your strongest opening line.
- Re-test if scores seem off -- the multi-persona evaluation
  can produce slightly different results each run.
