How it works

1

Enter your topic

Describe what you want to post about in a sentence or two. Be specific: the tool works better with clear direction.

2

Pick platform and tone

Choose where you're posting and the tone that fits your brand. Leave them blank for a general-purpose post.

3

Get your post

The tool returns a complete caption formatted for your chosen platform. Copy, edit if needed, and publish.

Platform-specific posts

Pick Instagram, LinkedIn, Facebook, X, or TikTok and the post is written in the length and style that suits that network.

Six tone options

Choose engaging, professional, casual, bold, playful, or formal to match your brand voice and the message you want to send.

Copy first, no templates

This is a text tool. You get the words for the post. It does not create images or design templates.

Full draft, not an outline

You get a complete post, not bullet points. Edit the details and publish it from the tool you already use.

No signup to try

Run the tool 3 times per day without creating an account. Add it to a Letaido workspace for unlimited runs and a saved brand voice.

Works for any topic

Product launches, team updates, industry news, behind-the-scenes posts. If you can describe it in a sentence or two, the tool can draft it.

How to get the most out of the social media post generator

This social media post generator turns a short topic into a draft for the network you pick. It works best when you give it clear direction and treat the result as a starting point you edit before posting.

Give your AI social media post generator a specific topic

Describe the angle or key message, not just the subject. Instead of 'new product launch', try 'launching our project management tool for remote teams, focusing on async collaboration features'. More context gives you a more relevant post.

If you want a specific call to action or a particular benefit in the post, say so in the topic field. The tool can work it into the copy instead of leaving it for you to add at the end.

Write for Instagram, Facebook and LinkedIn separately

Each network has its own rhythm. LinkedIn posts tend to be longer and more narrative, Instagram captions are punchier, X posts are short and direct, and TikTok captions are casual. Pick the platform and the tool adjusts length and structure to suit it.

If you are sharing one message on several networks, run the tool once per platform instead of pasting the same caption everywhere. A product update reads differently on LinkedIn than on Instagram or Facebook.

Use tone to control formality and energy

Tone changes more than word choice. 'Professional' keeps the post buttoned-up and fact-focused. 'Playful' adds humor and personality. 'Bold' makes stronger claims in punchier language.

If you leave tone blank, you get a balanced, engaging style. Try two tones on the same topic and keep the one that sounds most like your brand.

Edit the output so it does not sound generic

Add your own details, rewrite the opening line if it does not grab you, and swap generic examples for real ones from your work. Check any claim or number against what you actually offer before it goes live.

Check hashtags and emojis too. Depending on the platform, the post may include some. Keep what fits your account and delete the rest. In a Letaido workspace you can set a custom brand voice so every post starts closer to your final style.

Frequently asked

Can the generator write posts for Instagram, LinkedIn, Facebook and X? +

Yes. You can pick Instagram, LinkedIn, Facebook, X, or TikTok. You choose one platform per run. For versions on several networks, run the tool again with the same topic and a different platform.

What should I enter to get a good post? +

Describe the topic in a sentence or two, including the angle, the audience, and any call to action. 'Launching our project management tool for remote teams, focused on async work' beats 'new product'.

Does it add hashtags and emojis? +

It depends on the platform. The tool follows the usual style of each network, so an Instagram post is more likely to include hashtags and emojis than a LinkedIn post. Review them and add or remove any to suit your account.

Can I change the tone to fit my brand? +

Yes. Choose engaging, professional, casual, bold, playful, or formal. If none fits exactly, pick the closest and edit the post. In a Letaido workspace you can set a custom brand voice.

Is it free, and do I need an account? +

It is free to try in your browser with no account. You get 3 runs per day. Add the tool to a Letaido workspace for unlimited runs and a saved brand voice.

How do I keep AI posts from sounding generic? +

Give a specific topic with real detail, pick the tone your audience expects, and edit the result. Swap generic lines for your own examples, numbers, and phrasing before you post.

Does it create images or design templates? +

No. This is a copy-first tool that writes the text of the post. Add your own image or video in the app you use to publish.
