# Hookline

> A free LinkedIn writing studio: hooks that survive the see-more fold, posts in your own voice, a calm calendar and honest analytics. Optional AI.

Hookline is a free LinkedIn writing studio. Write posts in your own voice, get the hook past the see-more fold, check readability and AI-sounding phrases, plan a calm rhythm, post through LinkedIn's official API only when you press the button, and learn from your own analytics export.

AI is optional and runs on each user's own Anthropic API key, straight from their browser, so the key never reaches the server.

Who it's for: Professionals and founders who post on LinkedIn

## What it does
