Step by step
- 1
Ask ChatGPT for a list of TikTok ideas for your niche and pick the ones you will actually film.
- 2
Tell ChatGPT how often you post and let it place the chosen ideas on free days in Postika, pending approval.
- 3
Film in batches; for each clip, open the matching pending post in Postika.
- 4
Attach the video (or the slides for a photo carousel), check the caption and approve.
Example prompts
- Give me 20 TikTok hook ideas for a dog groomer. I'll pick five.
- Create TikTok posts for ideas 2, 5, 9, 14 and 18, one per day at 18:00 starting tomorrow, pending approval. Captions under 120 characters, two hashtags each.
- We post TikTok on Tuesdays, Thursdays and Sundays. Which of those days are empty in the next month?
- Write a caption for a photo carousel of 8 before-and-after haircuts and create it as a draft.
- Change the caption of my next TikTok to mention the 20% discount code AUTUMN20, as a new pending post at the same time.
What ChatGPT needs to know about TikTok in Postika
Postika passes ChatGPT each TikTok channel's rules: a video or images are required, captions go up to 2,200 characters, carousels take up to 35 images and posts take one video. Since the connector only carries text, ChatGPT creates TikTok posts as approval or draft, never as schedule or now. If it tried, Postika would answer that the post needs media.
The result is a calendar where each TikTok slot already has a caption and a time, waiting for the clip. That is a useful forcing function for creators who film in batches: you open the calendar and see exactly which videos are still missing. Format details are in TikTok scheduling.
Ideas fast, filming in batches
The workflow that fits ChatGPT best is quantity first, then selection. Ask for 20 ideas, pick 5, and let ChatGPT create the 5 posts. One filming session covers the week. If an idea doesn't work on camera, ask ChatGPT to delete that pending post (it asks before deleting) or replace it with another idea on the same day.
For photo carousels, ask ChatGPT for the slide text too, or have it generate slide images that you download and attach. Up to 35 images fit in one TikTok post in Postika; see TikTok photo carousels. Creators running several accounts can keep one project per account; see Postika for creators. A more source-driven workflow is in the Claude TikTok guide.
