Extend AI

Extend AI converts voice notes and rough text ideas into on-brand social posts by first learning from content you’ve already published. The setup runs once: paste a few existing posts, and the tool builds a style profile — tone, rhythm, vocabulary, sentence structure. After that, the loop is record or type a rough idea, receive formatted drafts for multiple platforms simultaneously, copy and adjust whatever single line you want to change, and publish. The vendor states first drafts arrive in under two minutes.

The differentiating claim is the input model. Where most AI writing tools start from a prompt and produce generic output, Extend starts from your own writing history. The vendor frames this directly: ‘better inputs, not better prompts.’ For professionals whose audience follows them specifically — consultants, executives, niche creators — that distinction determines whether the output is usable or embarrassing. The voice profile persists across sessions, so drafts for a Monday post and a Friday post maintain consistency without re-prompting.

Extend AI fits tightly into one scenario: a professional with an established posting voice who wants to post frequently without spending time writing. It supports LinkedIn posts, X posts and threads, Facebook and Telegram posts, Instagram captions, carousels, Reels and Shorts scripts, and hook ideas — all social, all short-form. The free plan covers core text formats and 10 generations per month with no credit card required. Carousels, Reels scripts, X threads, and unlimited generations are paid-only features. Teams running multilingual accounts get language switching on the free plan; unlimited multilingual generation is a paid-only feature. There is no API, no self-hosted option, and no agentic behavior — every draft is generated on demand by a human initiating a request.
