Questions
Answers in plain language
Does M18X Post Studio need a backend?
No. This version is an entirely static browser app. It uses clipboard access and platform share/composer URLs.
Does it auto-publish to social networks?
The publish button opens browser-safe platform share/composer flows and copies the prepared text. Fully automatic API posting would require OAuth and secure token handling.
What does Formatting do?
The studio converts markdown into styled social posts: emphasis becomes copy-pasteable Unicode styling, links become text plus URL, lists are normalized, and thread mode numbers each block.
Does it schedule posts?
No. The studio focuses on creating, previewing, copying, and handing off posts to each platform composer.
Is it free?
Yes. The static app is designed to be free to host and free to use under the M18X landing zone.
