What Postdiff is
Postdiff is a command line tool that drafts posts from your finished work. It provides drafts, not finished opinions, and every draft needs your approval before it can be used.

Terms of service
Plain language, no fine print tricks. Last updated October 2026. This is not legal advice, just how we run the project.
Postdiff is a command line tool that drafts posts from your finished work. It provides drafts, not finished opinions, and every draft needs your approval before it can be used.
Your writing samples, drafts, and posted content are yours. We claim no rights over them. If a draft quotes someone else, getting permission is on you.
Read every draft before you share it. Check facts, quotes, and code. We are not liable if a post contains a mistake, breaks a rule of a platform, or causes any loss.
The tool is provided as is, without warranties of any kind. It may change, pause, or stop working with a given provider if that provider changes its service. We will note breaking changes in the repo.
Do not misuse the tool to spam people, impersonate others, or break the law. If you do, that is on you, and we may stop supporting your use.
If these terms change, the new version will be posted on this page with a new date. Continued use after a change means you accept the new version.
