About Postmate
Postmate turns what you ship into social content. You connect GitHub with read-only OAuth access, and it pulls commit history, README files and language stats, then reads commit messages and file diffs to draft a post about the work rather than just repeating subject lines.
You pick a generation mode: a single commit post, a full project showcase, a three-post thread for X, or an opinion piece anchored to a trend. Four post styles are offered, including progress update, technical insight and build-in-public. A voice memory prompt and a tone slider shape the wording so drafts sound like you.
Nothing is published for you: you review the draft in the editor, then one click copies it to LinkedIn or opens the X composer. The site says drafts can be produced in under a minute. It can be started for free, and a pricing page lists paid options.
