MagicPost has two sets of AI tools. Both are optional. Writing, saving, scheduling and publishing all work without them.

​
Before you start

Three things must be in place:
  1. A model. Your administrator adds a provider API key and switches a model on under Publishing → Writing Models for text, and Publishing → Media Models for pictures and video. Until then you see An administrator needs to add a provider API key and switch a model on before this can be used. See AI models.
  2. Your plan. When billing is turned on for the site, your plan must include AI writing and AI media. Where it does not, the tool shows AI writing is not included in your plan (or AI media) with an Upgrade link, and the sidebar marks Brand voices as locked. See Billing and subscription.
  3. Credits. Each run costs credits. Your balance shows in the assistant and in the sidebar plan card. See Credits.
When billing is not turned on for the site, every AI feature is available and nothing is metered by plan. Admin accounts always have access.

​
Write with AI

Open the assistant from the composer’s caption toolbar with Write with AI, or press Ctrl J. The window header shows what a run costs, for example Costs 2 credits a run, and your Balance. With an unlimited balance it reads Runs are covered by your unlimited credits.
1

Pick what you want

Choose one of the eight modes at the top of the window. Each has a one-line hint under it.
2

Describe the post

For Write, the box is labelled What is the post about? A short brief works best: what you are announcing, who it is for, and what you want people to do. The other modes use a box labelled The post to work from. For modes that rework text (Rewrite, Shorten, Hook, Per network and Translate) it is filled with your current caption when you switch to the mode. For From a link, paste a public page address under Link to the page and, if you like, add What to bring out (optional). The link is added to your post when you use an option, if the post has none yet.

Set the options

  • Voice applies one of your brand voices. Set one up and Manage open the Brand voices page. Your default voice is preselected.
  • Language is the language of the result, or Translate into for Translate. The list has 28 languages from English to Vietnamese. A voice with a language sets it for you.
  • Tone is Friendly, Professional, Playful, Bold or Informative. It is hidden for Translate and Hashtags.
  • Options is how many versions to write, from 1 to 5. It is hidden for Per network.
  • Add hashtags and Add emoji add them to the text. They are hidden for Hashtags, Translate and Hook.
  • Look at the attached picture lets the model read up to four attached images when the chosen model can see pictures. Otherwise you see This model cannot look at the attached pictures.
  • Writing model appears when your administrator switched on more than one model.

Generate

Select Generate. The button reads Writing… while it works, then Try again once there are results.
5

Use a result

Each option shows its length with Use this, which replaces the caption you are editing (the shared caption or the open channel’s own caption), and Save, which keeps it in your Captions library without changing the post. For Hashtags the button is Append.
If you open the assistant on a caption you already wrote, the brief is pre-filled with it and the mode starts on Rewrite.

​
Per network versions

With Per network, pick your channels first. MagicPost writes one version per selected network, kept under that network’s character limit. It still counts as a single run at the usual price. Select Use on N channels under a network’s version to put it on every selected channel of that network, or Use every version to apply all of them. A version over the limit is flagged Over the limit. Trim it after using it, or run again.

​
Length

In every other mode, results are kept under the character limit of the tightest channel selected, as the line under the brief tells you.

​
Earlier runs

Switch to the Earlier runs tab to see your last ten runs. Every run you pay for is kept there, so an option you passed over can be used later for free. Select Use or Append next to an option. Nothing is charged again.

​
How credits are charged

  • Each run costs the model’s credit price, whatever you asked it to do. Adapting a post for five networks is one run.
  • The price is held before the model is called and charged only once a usable answer comes back. If the provider fails, the hold is released and you pay nothing.
  • A run is limited to 20 for each person in any 10 minutes.
  • If your balance is too low, the window shows how many credits the run needs against what you have, and the run is refused until you add credits or your allowance refreshes.
Alt text suggestions are separate runs at the same model price, and show the cost when they finish.

​
Alt text suggestions

In the composer, open Alt text and crop on an attached picture and select Suggest alt text. The model looks at the picture and your caption and returns a description of up to 250 characters. Read it, correct it if needed and select Save alt text. It works for pictures only. See Composer.

​
Create and edit pictures and clips

The media studio makes new pictures, changes an existing picture, or turns a picture into a short clip. What you make is saved to your media library, in the Made with AI folder.

​
Open the studio

  • In Library → Media, select Create with AI.
  • In the composer’s Assets panel, select the sparkles button, Create a picture with AI. Results can then be attached to the post straight away with Add to post.
  • In the composer, open an attached picture’s Alt text and crop panel and choose Edit with AI.
  • On a finished run, choose Edit this picture or Bring this picture to life.
The window title changes with what you are doing: Create with AI, Edit with AI or Bring a picture to life.

​
Make a picture

1

Choose Picture

The Picture and Video switch appears when a video model is switched on.
2

Describe it

Under What should it show?, describe the picture. For example: A ceramic mug on a linen tablecloth, morning light, soft shadows, no text. The description can be up to 4,000 characters. To edit, the box asks What should change? and you can say Swap the background for a sunny kitchen and keep the mug exactly as it is. The original stays in your library as it is.
3

Pick model, shape and number

Choose the Model, the Shape the model offers, and How many pictures to make, up to the model’s maximum.
4

Create

Select Create (Make the change when editing). The run appears under Recent and shows Starting…, Making it… and finally the pictures.

​
Make a clip

Choose Video. Describe the clip, or, when you started from a picture, how it should move (How should it move?). Pick a Model that supports it, a Shape and a Length in seconds from the model’s options, then select Make the clip. A clip takes a few minutes. You can close the window and come back, and the clip shows as Rendering… in the meantime. Only models that can start from a picture are offered when you began from one.

​
Cost

  • A picture run costs the model’s price for each picture. The credits are held while it is made and charged only for pictures that arrive.
  • A clip costs the model’s price for each second of length. It is held while the clip is made and charged only if it arrives.
  • Stop appears next to a run that is still Starting…. It cancels the run and returns the held credits.
  • You can start up to 12 picture runs and 6 clip runs in any 10 minutes.
If a run fails the window shows Failed with the reason, and a Stopped label for runs you stopped.

​
Marking and publishing

Files made here show a Made with AI badge in the composer. When you attach one to a post, the composer notes that TikTok and YouTube are told the content is AI-made and label it for viewers.
Say what must stay as well as what should change. The studio’s own example for editing is Swap the background for a sunny kitchen and keep the mug exactly as it is.
