# Hook & Virality Scorer - Rank Titles Before Posting (`dami_studio/hook-virality-scorer`) Actor

Stop guessing which title will pop. Feed it your hook ideas and get a 0-100 virality score, an A-F grade, a six-part breakdown of curiosity, emotion, power words, specificity, relatability and length, the exact words that scored, and concrete rewrites. Batches rank best-first. No AI key, instant.

## Pricing

from $3.00 / 1,000 hook scoreds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Hook & Virality Scorer

Score a title, hook, or opening line for scroll-stopping power and get back a 0-100 number with a letter grade. It's built for short-form creators and copywriters who are sitting on five title ideas and want a fast, repeatable way to pick one instead of arguing about it. Pass a batch of variants and it ranks them best-first.

### How it works

It runs a deterministic rule pass over the text. It counts curiosity phrases, emotion and high-stakes words, power words, numbers, questions, and "you"/"I" framing, then scores six weighted dimensions and applies penalties for filler and excess ALL-CAPS. No AI, no API calls, so the same input always returns the same score.

### Input

You don't have to set anything beyond the text. Pass `text` for one string or `texts` for a batch.

| Field | Required | Notes |
|-------|----------|-------|
| `texts` | no | Array of titles/hooks/scripts to score. Strings or objects (it reads `title`, `hook`, `text`, or `scriptText`). Pass several to compare variants. |
| `text` | no | A single title or hook, as an alternative to the array. |
| `type` | no | `auto`, `title`, or `script`. Auto treats anything up to 18 words as a title. Controls the length scoring. Default `auto`. |
| `rankResults` | no | Sort output best-first and add a `rank`. Default `true`. |

At least one of `text` or `texts` must resolve to a non-empty string, otherwise the run fails.

### Output

One dataset item per scored hook. Each item has the `score` (0-100), `grade` (A through F), and the original `text`, plus a `breakdown` object with the per-dimension points (curiosity, emotion, powerWords, specificity, relatability, length), a `signals` object listing exactly what it matched (word count, numbers, questions, the specific power/curiosity/emotion/filler words found), and a `suggestions` array of concrete rewrites for whatever scored low. When ranking is on, items also carry a `rank`.

### Example

```json
{
  "texts": [
    "I tried the viral 5am routine for 30 days",
    "You won't believe what happened when I confronted my MIL",
    "My morning routine"
  ],
  "type": "auto",
  "rankResults": true
}
```

### Pricing

$0.003 per hook scored, pay-per-result, no subscription.

### Notes

The scoring is keyword and pattern based and tuned for English. It rewards the usual viral signals (open loops, stakes, specificity), so treat it as a fast first-pass filter and A/B comparison tool, not a guarantee that a high-scoring hook will actually go viral.

# Actor input Schema

## `texts` (type: `array`):

Titles, hooks, or scripts to score. Strings OR objects (uses title/hook/text/scriptText). Pass several variants to rank them.

## `text` (type: `string`):

A single title/hook to score (alternative to the array).

## `type` (type: `string`):

Score as a short title, a longer script/hook, or auto-detect.

## `rankResults` (type: `boolean`):

Sort results best-first and add a rank.

## Actor input object example

```json
{
  "texts": [
    "I tried the viral 5am routine for 30 days",
    "You won't believe what happened when I confronted my MIL",
    "My morning routine"
  ],
  "type": "auto",
  "rankResults": true
}
```

# Actor output Schema

## `results` (type: `string`):

Result rows / metadata are stored in the default dataset (one row per item).

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "texts": [
        "I tried the viral 5am routine for 30 days",
        "You won't believe what happened when I confronted my MIL",
        "My morning routine"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("dami_studio/hook-virality-scorer").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});
