PostBoost AI Assist: improve the writing, fix spelling and grammar, continue, expand, shorten, simplify, or make a post friendlier, more formal, edgier or more engaging

Alt text on every image

Clear AI labels

Mark a post as AI-generated from the API or your agent. Posts that use images from our AI tools are labelled automatically.

Everything in AI create

How it works

  1. Set your brand voice

    Describe your business, audience, topics and tone once.

  2. Paste a link or write a prompt

    A web page, a YouTube video, a PDF or your own text.

  3. Edit the draft and schedule it

    Change what you like, then schedule or queue it.

Do it from the dashboard, your agent or your code

Dashboard

Open Repurpose under Tools, paste a link and pick the accounts.

Ask your agent

“Turn this blog post into posts for LinkedIn and Threads and save them as drafts.”

How many AI credits do I get?

Free: 10 text and 3 image credits; Pro: 100 text and 30 image credits; Pro Max: 300 text and 100 image credits; Agency: 1000 text and 300 image credits. Credits reset every month.

Does AI publish anything by itself?

No. Captions and repurposed posts are drafts. You or your agent decide when to schedule them.

Can it repurpose a YouTube video or a PDF?

Yes. Paste a YouTube link, a web page or a PDF, or paste text. You get one draft with a caption for each account you pick.

What is a brand voice?

A short profile of your business, audience, topics and tone. PostBoost uses it for captions, repurposing and image prompts so posts sound like you.
