Postmately

TikTok carousel scheduler

Updated 09.11.2026

Postmately makes your TikTok carousels and posts them on schedule: a month of photo posts from one link to your site, approved with one tap. No designing slides at night, no posting by hand every day.

Carousels hold attention on TikTok because people stop to read each slide. The hard part is making one every day: a topic, a hook, five or six slides that look like your brand and a caption. A scheduler that only queues files leaves all of that to you.

How it works

  1. Connect TikTok on TikTok’s own login screen. Postmately never sees your password.
  2. Paste your website. Postmately writes a month plan: topics, hooks and the carousel for each day.
  3. Approve the drafts. Each carousel arrives in Telegram or email a day early; edit any slide or approve as is.
  4. It posts on time through the Content Posting API, and views come back next to each post.

Who it is for

  • Small businesses and experts who want a daily TikTok rhythm without a designer.
  • Brands that post the same idea to TikTok and Instagram as carousels.
  • Agencies that run carousels for several clients.

Who it is not for

  • Creators whose posts live on a specific trending sound: post those from the app.
  • People who want AI-generated pictures: Postmately uses your photos or licensed stock, not AI images.

FAQ

Can you schedule a TikTok carousel? +

Yes. Postmately publishes TikTok photo posts through TikTok’s official Content Posting API at the time you choose, up to 35 images per carousel.

Do I have to design the slides? +

No. Postmately makes the carousel from your website or a topic: a hook slide, the points and a call to action, in your colours, with your photos or a licensed stock pack. You can edit every line before it goes out.

What about trending sounds? +

Photo posts made through the API can get background music automatically, but a specific trending sound is picked in the TikTok app. If the sound is the point of the post, download the slides and post them natively.

What size are the slides? +

Vertical 1080×1920. TikTok takes JPEG or WebP up to 1080p for API photo posts; Postmately converts the slides for you.

Can the same carousel go to Instagram? +

Yes. The same slides can go to Instagram, Pinterest, Telegram, VK and Bluesky, each with its own caption.

Is posting through a scheduler safe for my TikTok account? +

Publishing through the official Content Posting API is allowed; TikTok asks you to confirm privacy and interaction settings, which come from your own account. What hurts accounts is spam behaviour, not the API.

What does it cost? +

Free to start: a month plan, 3 carousels and 1 video, no card. AI Autopilot is $59 a month with 6,000 credits; a carousel costs 20 credits, so about 300 carousels a month.
