Heddle

A writing studio for thoughtful social content, in your own voice.

Heddle helps you turn a question, an article or your collected notes into posts and threads for X and LinkedIn. You import sources, Heddle extracts the key ideas with their supporting passages, and an AI writing assistant helps you find an angle, research it, build an outline and shape a draft that you review and edit before publishing.

Build a personal library from URLs and documents (PDF, DOCX, TXT, Markdown), with extracted ideas linked to their sources.
Discover topics from recent conversations and your saved material.
Research with your library and the web, and see which material supports your piece.
Draft hooks, outlines and posts with Light or Heavy review, then edit them yourself.
Keep writing preferences and past work you choose to save, with your current instructions always taking priority.
Publish to the X and LinkedIn accounts you connect, organized by publishing identity.
