AI assistant
On this page
Robopost's AI can write captions, suggest hashtags, fix spelling, turn an image, a video, a web page or your own documents into ready-to-post ideas, generate images, and produce narrated short videos.
You need: nothing extra to start. AI features are part of your plan; some of them count against a monthly allowance (see How many AI credits do I have?).
What can the AI do, and where?
| Tool | Where | Guide |
|---|---|---|
| Post ideas from images, a video, a URL, a prompt or a knowledge base | Posts → New post | Post ideas |
| Write a caption | Composer, Compose Text with AI | Below |
| Fix spelling and grammar | Composer, Check Spelling | Below |
| Suggest hashtags | Composer, Insert Hashtag | Below |
| Generate an image | Composer, Insert Image | AI images |
| Rephrase a repeating post, new image each time | Composer, Recurring post? | Schedule and repeat |
| Captions and images for each new article or product | Posts → Automations | RSS feeds |
| Faceless videos, blog to video, captions, shorts | Content → Videos by AI | Faceless videos |
| Teach the AI about your business | Content → AI Assets | Knowledge bases |
Generate posts from an image, a video, a URL or a prompt
Click Posts → New post (open it). Under AI-Powered Creation, pick From Images, From Video, From URL, From Prompt or From Knowledge Base. Give the AI its source, adjust the word count, tone, hashtags and emojis, and click Generate Posts. Each idea has a Create Post button that opens it in the composer. The full guide is Generate post ideas with AI.
Write a caption in the composer
- In the composer, click the magic wand button (its tooltip reads Compose Text with AI).
- In What type of post would you like to compose?, describe the post, for example "announce our summer sale, 20% off all shoes until Sunday."
- Choose Include Emojis, Include Hashtags, the Approximate Word Count and the Voice Tone.
- Optional: switch on Use knowledge base and pick one in Select knowledge base, so the AI uses your own information.
- Click Generate suggestion. Not happy? Change the description and generate again.
- Click Copy to clipboard and paste the text into your post.
The AI writes in the language of your description.
Fix spelling and grammar
In the composer, click the spell-check button (its tooltip reads Check Spelling). The Spell Checker window shows a corrected version; click Apply Fix to replace your text with it.
Get hashtag suggestions
In the composer, click the hashtag button (Insert Hashtag). The Hashtags window opens on AI Suggestions, with hashtags based on your text and your first image. Click Confirm to add them to the post. The Hashtag Groups tab inserts your saved groups instead: see Hashtag groups.
How many AI credits do I have?
Account → Plan Usage (open it) shows your monthly allowances. The AI-related ones:
| Allowance | What uses it |
|---|---|
| AI Credits | One per post idea run (however many ideas it returns), including Blog to Video |
| Generated Faceless Videos | One per finished video: series, Blog to Video and automations |
| Captioned Videos | One per video finished with Add Captions to a Video |
| Long to Shorts Videos | One per video finished with Convert Long Videos to Shorts |
Each allowance resets on the date shown on Plan Usage. If you've used one up, Robopost shows Plan Limit Hit instead of starting the job. Video credits you buy with Buy Credits on Plan Usage carry over from month to month. See Usage and limits.
Who can use the AI tools?
Anyone who can create posts can use the composer's AI buttons and Post Ideas by AI. Videos by AI needs the Admin or Manage AI Videos right, and AI Assets (knowledge bases, voices, music) needs Admin or Manage AI Assets. See Team members and roles.
