Common questions
Are documents uploaded to a GrayCat server?
No. GrayCat Markdown does not operate a document server. Files remain in a local folder you choose or in Apple iCloud. Cloud AI is optional; relevant text goes directly to the provider you configure only after you confirm the scope and start the action.
Can Mac and iPhone/iPad use the same documents?
Yes. Use the app's dedicated iCloud Documents folder, or authorize your own writing folder through the system file picker.
Why might images need to be re-uploaded on a publishing platform?
Clipboard and image-hosting rules differ by platform. Select the matching publishing preview first; if the destination rejects local images or data URLs, use that platform's upload tool.
Where can I find the installed version?
On Mac, choose “About GrayCat Markdown” from the app menu. On iPhone or iPad, open Settings → General → iPhone/iPad Storage → GrayCat Markdown.
