Questions

What is PostOnce?

PostOnce is a crossposting tool. You post on your main app and it publishes the post to your other accounts on TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Threads, Bluesky and Pinterest, through each app's official posting API.

Will my posts actually go out?

Yes. Every post goes through each app's official API, and you get an email if one ever fails.

Do I need to download or upload anything?

No. Post on your main app. PostOnce does the rest.

Which apps does it work with?

TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Threads, Bluesky and Pinterest.

Does PostOnce post photos, carousels and Stories?

Yes. Photos and carousels go out as image posts, like TikTok photo posts and Facebook albums. Instagram and Facebook Stories go out as Stories on your other Instagram accounts and Facebook Pages.

Can I change captions for each app?

Yes. Set caption rules once for each app, like removing a DM prompt on Instagram or adding #Shorts on YouTube. AI can rewrite a caption for LinkedIn.

Can I schedule posts instead of posting right away?

Yes. Each new post can go out right away or wait for your time slots in each app.

Can I post from ChatGPT or Claude?

Yes. PostOnce has an MCP server, a public API and ready-made skills, so you can post, schedule and read analytics from Claude, ChatGPT, Cursor and other AI tools.

Does PostOnce show analytics?

Yes. See views, likes, comments and shares for every video on every app on one page, and which posts beat your usual views.

Will it hurt my reach?

No. Instagram's head says schedulers don't affect reach, and PostOnce posts through each app's official posting API, so it goes out like a normal upload. What affects reach →

Will there be a watermark?

No. You get clean files, and TikTok's clean version where available.

How fast do posts go out?

Half are live within about 10 minutes, most within 20.

Can I repost my older posts?

Yes, 1 to 5 a day from your back catalog.

Do I have to share my passwords?

No. You use each app's official login.

What's in the free trial?

7 days, up to 10 posts, no card. Full refund within 7 days on paid plans.
