WriteHero: LinkedIn post checker

Check a LinkedIn post before publishing: character count against LinkedIn's 3000-character limit, the text likely shown before "see more" on desktop, a hook score, Markdown that LinkedIn will not render, placeholders, and phrases that read as AI-written. Returns concrete issues to fix.

{
  "type": "object",
  "properties": {
    "post": {
      "type": "string",
      "minLength": 1,
      "description": "The full post text."
    }
  },
  "required": [
    "post"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Convert Markdown into text that pastes cleanly into LinkedIn: **bold** and headings become Unicode bold, *italic* becomes Unicode italic, list markers become bullets, Markdown links become plain URLs. Optionally replaces em dashes.

{
  "type": "object",
  "properties": {
    "post": {
      "type": "string",
      "minLength": 1,
      "description": "Post text, Markdown allowed."
    },
    "replace_em_dashes": {
      "default": false,
      "description": "Replace em dashes with commas.",
      "type": "boolean"
    }
  },
  "required": [
    "post"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Restyle a short piece of text with Unicode letters that keep their look when pasted into LinkedIn (bold, italic, bold italic, serif, cursive, strikethrough, underline). Use sparingly; screen readers may read styled letters poorly.

{
  "type": "object",
  "properties": {
    "text": {
      "type": "string",
      "minLength": 1,
      "description": "The words to restyle."
    },
    "style": {
      "default": "bold-sans",
      "description": "Style to apply.",
      "type": "string",
      "enum": [
        "bold-sans",
        "bold-serif",
        "bold-italic-sans",
        "bold-italic-serif",
        "bold-script",
        "bold-fraktur",
        "italic-sans",
        "italic-serif",
        "script",
        "strikethrough",
        "short-strike",
        "slash",
        "underline",
        "double-underline"
      ]
    }
  },
  "required": [
    "text"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Opening-line templates for a LinkedIn post, filled with the user's topic, audience and result. Anything the user has not supplied stays in [brackets] to replace with a real detail; nothing is invented.

{
  "type": "object",
  "properties": {
    "topic": {
      "type": "string",
      "maxLength": 80,
      "description": "What the post is about, e.g. hiring engineers."
    },
    "audience": {
      "default": "",
      "description": "Who the post is for, e.g. founders.",
      "type": "string",
      "maxLength": 80
    },
    "result": {
      "default": "",
      "description": "A real result the user can back up, e.g. hired 4 engineers in 30 days.",
      "type": "string",
      "maxLength": 120
    }
  },
  "required": [
    "topic"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Profile headline options built only from the user's role, audience, outcome, proof and keywords. Every option fits LinkedIn's 220-character headline limit. Does not change the profile.

{
  "type": "object",
  "properties": {
    "role": {
      "type": "string",
      "minLength": 1,
      "maxLength": 120,
      "description": "Current or target job title."
    },
    "audience": {
      "default": "",
      "description": "Who the user helps.",
      "type": "string",
      "maxLength": 180
    },
    "outcome": {
      "default": "",
      "description": "The result they deliver, e.g. book more sales calls.",
      "type": "string",
      "maxLength": 180
    },
    "proof": {
      "default": "",
      "description": "A credential or result they can verify.",
      "type": "string",
      "maxLength": 180
    },
    "keywords": {
      "default": "",
      "description": "Skills people search for.",
      "type": "string",
      "maxLength": 180
    },
    "goal": {
      "default": "general",
      "description": "clients: win clients; job: get hired; general: both.",
      "type": "string",
      "enum": [
        "clients",
        "job",
        "general"
      ]
    },
    "tone": {
      "default": "plain",
      "description": "warm phrases the value as \"Helping...\"; plain and bold as \"I help...\".",
      "type": "string",
      "enum": [
        "plain",
        "bold",
        "warm"
      ]
    }
  },
  "required": [
    "role"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Return a link to an approximate preview of the post in the LinkedIn feed on mobile and desktop, including about where "see more" cuts it. Pass author_name and author_headline when you know them. Opening the link saves and publishes nothing. The post text travels in the link, so share it only with people who should read the draft.

{
  "type": "object",
  "properties": {
    "post": {
      "type": "string",
      "minLength": 1,
      "description": "The post text."
    },
    "author_name": {
      "description": "Name shown on the preview.",
      "type": "string",
      "maxLength": 80
    },
    "author_headline": {
      "description": "Headline shown under the name.",
      "type": "string",
      "maxLength": 220
    }
  },
  "required": [
    "post"
  ],
  "$schema": "http://json-schema.org/draft-07/schema#"
