An AI social media post generator that keeps your voice
Postuva's AI turns one idea into a native post for each network you pick: a professional LinkedIn post, a 280-character X post, a conversational Bluesky post and a friendly community announcement. It keeps your facts, links and voice, respects every character limit, and you approve each version before it's scheduled.

What makes a good AI-generated social post?
- It doesn't invent facts, numbers, quotes or offers. Postuva's AI is instructed never to do this.
- It fits the network: hooks for X, short paragraphs for LinkedIn, a conversational tone for Bluesky.
- It stays within the limit, so nothing gets cut off mid-sentence.
- It sounds like you, because it starts from your words.
Is AI-written content bad for reach?
Networks rank posts on engagement, not on how they were drafted. Generic, empty posts perform badly whoever writes them. Starting from your own idea and editing the result keeps posts specific, which is what audiences respond to.

What does AI tailoring change, and what doesn't it?
The instructions the AI works under are strict: never invent facts, numbers, quotes or offers, keep the author's voice, and stay within every character limit. Your post text is treated as content to rewrite, never as instructions, so a post that mentions “ignore the rules” is simply rewritten like any other.
| AI adapts | AI keeps exactly |
|---|---|
| Length, to fit each network's limit | Your facts and numbers |
| Structure: hooks, paragraphs, line breaks | Links and URLs |
| Tone for the network (professional, punchy, conversational) | Discount codes, names and dates |
| Hashtags (at most 3, where customary) | Your language |
Examples: one idea, three networks
Idea: “Our autumn single-origin from Huila, Colombia is back. Notes of red apple and panela.”
LinkedIn: a short story about the six-year relationship with the farm, the tasting notes, and a closing question about brewing methods, around 250 characters spread over three short paragraphs.
X: “The Huila single-origin is back 🍎 Red apple, panela, long sweet finish. Our best harvest yet from the same family farm we've worked with for 6 years.” That's 149 characters.
Bluesky: the original one-liner, kept short and conversational for an 85-character post.
How many AI credits do I need?
One credit tailors one idea for every network you selected, whether that's two networks or seven. If you post five ideas a week, that's about 20 credits a month, which the free plan covers. Creator includes 300, Pro 1,500 and Agency 6,000. Credits reset monthly, and a failed request never uses one.
AI post generator vs general-purpose chatbots
You can paste a post into a general chatbot and ask for versions for each network. It works, but it takes several round trips: explain the limits, copy each answer back, check the character counts, paste into each network's app. An AI built into the scheduler skips all of that because it already knows which networks you selected and their limits, and its output lands directly in the right tabs, ready to schedule.
| General chatbot | Postuva Tailor for each network | |
|---|---|---|
| Knows your selected networks | No, you explain | Yes |
| Respects each character limit | Sometimes | Yes, checked and enforced |
| Output goes straight into the post | Copy and paste | Yes, one tab per network |
| Then schedules it | No | Yes |
Frequently asked questions
Which AI model does Postuva use?
Postuva uses Anthropic's Claude models to rewrite posts.
Do failed AI requests use credits?
No. A credit is only used when the rewrite succeeds.
Can I turn AI off?
AI only runs when you click Tailor for each network. Otherwise your text is posted exactly as written.
Is the AI social media post generator free?
Yes, the free plan includes 20 AI credits a month. Each credit tailors one idea for all the networks you selected.
Does the AI work in languages other than English?
Yes. It writes in the language of your original post.
Can the AI write a post from scratch?
It's designed to adapt your idea rather than invent one. Give it a sentence or two and it does the rest.
Is my content used to train AI models?
Your post text is sent to the AI model only to produce your tailored versions. We don't use your content to train models.
How long does AI tailoring take?
Usually a few seconds. The versions appear in each network's tab as soon as they're ready.
