Most captions don’t need to be written from nothing. They need a first draft, or a second pass on the one you already have.
That is what the caption assistant in BulkPublish is for. It sits in the composer, next to the text you are writing, and it only ever suggests. Nothing changes until you pick an option.
Where to find it
Open the composer and click AI beside the caption box. A menu opens with a prompt field at the top and a list of actions below it.
What the menu offers depends on what is in the composer:
- An empty caption: describe the post and it writes options from scratch
- A caption already written: every editing action works on it
- Some text selected: the actions work on just that selection
- An image attached: you can ask for a caption for the image itself
Writing a new caption
Type what the post is about into the prompt field and run it. You get three different options, each written for the network you are composing for.
The description doesn’t have to be polished. “Summer sale starts Friday, 20% off everything, ends Sunday” is plenty. If there is already a draft in the composer, the assistant reads it for reference, so you can describe the change in direction instead of starting over.
Editing what you have
These work on the whole caption, or on your selection if you have one:
| Action | What you get |
|---|---|
| Improve writing | Two clearer, more engaging versions with the same meaning |
| Rephrase | Three new wordings of the same idea |
| Make shorter | Two tighter versions |
| Make longer | Two versions with more detail |
| Add hashtags | Your caption unchanged, with 3–6 relevant hashtags at the end |
| Add emojis | Your caption with a few emojis added, wording kept |
| Fix spelling & grammar | One corrected version, nothing else changed |
| Change tone | Two rewrites in the tone you pick |
The tones are Professional, Casual, Funny, Inspirational and Informative.
Changing just one sentence
Select a sentence, then type an instruction into the prompt field instead of picking an action. “Mention that shipping is free” or “make this sound less like an ad” works.
The assistant rewrites only the passage you selected, and it reads the rest of the caption so the new sentence still fits around it. You get one version rather than three, because a specific instruction wants doing, not guessing at.
Captioning an image
Attach an image and choose Caption this image. The assistant looks at the picture and writes three options for it.
Add a line in the prompt field first if there is context the picture can’t show: the product name, the event, the offer. It gets woven into the options.
It writes for the network
Every suggestion is written for the platform you are composing for. Captions for X aim to fit its character limit, LinkedIn gets a different register than Instagram, and so on.
If you write one caption per network in the composer, run the assistant on each one. A LinkedIn post shortened for X is usually better than an X post padded out for LinkedIn.
How much you can use it
Each plan includes a monthly allowance:
| Plan | Included each month |
|---|---|
| Free | 50 generations |
| Pro | 300 generations |
| Business | 1,000 generations |
A text action uses one generation. Captioning an image uses two. The allowance resets every month, and if you run out you can buy credits from the assistant’s menu or from Settings, so you are never stuck halfway through a batch.
Getting drafts worth keeping
A few habits make a big difference:
- Give it the facts. It can’t know your prices, dates or product names unless you put them in the prompt.
- Edit the winner. Pick the closest option, then change a word or two. That is faster than asking again.
- Use selection. Rewriting one weak sentence keeps the parts that already sound like you.
- Read before you schedule. The assistant is good at wording and knows nothing about what happened this morning.
That last one matters most. The assistant drafts; you decide what goes out under your name.
