AI social media post generator: caption, image, video, and carousel in one

Open the chat or the content generator, describe what you want in plain language, and pick your platforms. Brandlix writes the caption in your brand voice, generates a matching image, video, or carousel, and produces a tailored version for each network. You review the drafts, make any edits, then schedule or publish them directly to your connected accounts. The whole flow, from idea to live post, happens in one place rather than across a writer, a design tool, and a separate scheduler.

Yes. Brandlix generates images with Google Gemini in square, portrait, and landscape ratios, so most posts ship with a ready-to-use visual rather than a caption that still needs design work. You can also generate short-form video with Kling or Seedance, and build multi-slide carousels where the AI writes each slide and renders the artwork. Text and visuals come out of the same prompt, so the image actually matches what the caption is about instead of being a generic stock photo.

Brandlix has a permanent free plan, so you can generate posts and try the AI without paying. Generation uses credits, and the free tier includes a starting allowance. Paid plans add more credits and capacity: Lite is $9 per month, Creator is $29, Pro is $79, and Business is $199. Image, video, and carousel generation cost more credits than plain captions because they use heavier models, and your plan determines how much you can generate each month.

Yes, that is the point of brand voice training. You teach the AI your tone, style, audience, and the words you do and do not use, and it applies that to every caption it writes. The output reads like your team wrote it, not like generic AI filler, across all platforms and all 9 supported languages. You can refine the voice over time, and you can always edit any draft before it publishes, so nothing goes out that does not sound like you.

Brandlix generates and publishes to 10 platforms: Instagram, Facebook, LinkedIn, TikTok, X (Twitter), YouTube, Pinterest, Threads, Bluesky, and WordPress. The generator does not just copy one caption everywhere. It rewrites the length, tone, hashtags, and formatting for each network, because what performs on LinkedIn is not what performs on TikTok. You write the idea once and get a version tuned for every account you have connected.

Those tools are AI-assisted: the AI suggests a caption and you do the rest yourself. Brandlix is agentic. An AI agent with over 100 tools can write the post, generate the image, video, or carousel, schedule it at a good time, run A/B tests, and pull analytics, all from one natural-language chat. Instead of getting suggestions, you get the whole workflow executed end to end, then choose what goes live.

Always. Nothing publishes automatically unless you set it up that way. Every caption is editable, you can swap or regenerate any visual, and you can ask the AI to rework a draft to be shorter, bolder, or in a different angle. Once you are happy, send it live immediately or schedule it for later. You stay in control of every post, with the AI doing the heavy lifting of writing, designing, and adapting it per platform.
