AI Social Media Post Generator

Branded Instagram, Facebook, and X posts with on-image text — in the right platform ratio.

How do I generate a social media post with AI?

Describe the post in Renoise Canvas — brand palette, the text overlay in quotes, and the platform ratio (1:1 for Instagram square, 9:16 for Stories, 16:9 for Facebook/X cover) — then generate on Nano Banana Pro. It renders in-image text at ~94% accuracy and supports ten ratios, so the post comes out sized right and the copy reads cleanly.

Social posts that look on-brand

What social media post generation looks like in Renoise.

Readable text overlay

Nano Banana Pro renders on-image copy at ~94% accuracy — quote the text and name the style.

Platform-correct ratios

Set 1:1 for Instagram feed, 9:16 for Stories and Reels, 16:9 for Facebook and X — all from one model.

Brand colors and style

Prompt the palette, mood, and visual style so posts stay consistent across a campaign.

Generate a social post in 3 steps

From a brief to a platform-ready branded post with legible text.

  1. Typing a social media post prompt with text overlay in quotes in Renoise Canvas
    Step 1

    Write the brief

    Name the platform ratio and put the text overlay in quotes — '1:1 Instagram post reading "NEW DROP", bold sans, brand-blue background, product centered'.

  2. Selecting Nano Banana Pro from the model dropdown in Renoise Canvas for social post generation
    Step 2

    Select Nano Banana Pro

    Pick Nano Banana Pro from the model bar — Studio-grade finish with multi-ratio support and strong text rendering.

  3. Exporting a finished AI social media post at high resolution from Renoise Canvas
    Step 3

    Iterate and export

    Generate, tweak colors or copy, then export at up to 4K. Proofread the text overlay before posting.

Posts for any platform

Instagram feed, Stories, Facebook, X — all from one canvas session.

Which model for social posts

Both live in the same Renoise Canvas. Nano Banana Pro for most branded posts — strong text rendering and multi-ratio. GPT Image 2 when the brief is complex or you fuse reference images from a brand library.

Branded social posts: why size and text both matter

Two things kill a social post before anyone reads it: the wrong crop and unreadable text. Each platform has a native ratio — Instagram feed expects 1:1 or 4:5, Stories and Reels are 9:16, Facebook and X links render best at 16:9. Generating at the wrong ratio means the platform auto-crops the image and your text disappears into the bleed. Setting the ratio explicitly in the Renoise Canvas prompt before generating avoids the re-crop entirely.

Text overlay is the second variable. Nano Banana Pro renders in-image copy at around 94% accuracy — higher than most image models, but not infallible. The technique that makes the biggest difference is quoting the exact words: 'reading "NEW DROP THURSDAY"' tells the model to treat that string as literal copy rather than a stylistic texture. Keep overlay copy short: a headline up to five or six words renders far more cleanly than a long sentence. If the post needs a longer caption, that lives in the social platform's post field, not in the image.

For a campaign where every post needs to match a brand guide, use an earlier post as a reference image in the next Canvas generation. Prompt for the same palette, typeface style, and layout, and the model carries consistency across the batch without you rebuilding the brief each time. The output is generative — not a locked template — so there is natural variation, which is actually fine for feed aesthetics.

Frequently asked questions

1.How do I generate a social media post with AI?

Describe the post in Renoise Canvas — platform ratio, text overlay in quotes, brand colors — then generate on Nano Banana Pro. It renders in-image text at ~94% accuracy across ten ratios. Proofread the copy, export at up to 4K.

2.What Instagram sizes can I generate?

Square 1:1 for the feed, 4:5 portrait for a taller feed card, and 9:16 for Stories and Reels. Set the ratio in your prompt; Nano Banana Pro handles it natively — no manual crop after export.

3.Can I use this for Facebook and X as well?

Yes. Facebook event headers and link previews render best at 16:9; X cards are also 16:9. Name the ratio and the platform in the brief and the model generates to fit.

4.How is a social post different from a flyer or poster?

Social posts are sized for platform feeds and optimized for quick scroll-stopping impact — short copy, platform-native ratios. Flyers are compact handouts for events with more detail. Posters are larger print or display pieces. For event flyers, see the flyer guide; for print posters, see the poster guide.

5.Can I keep branded posts consistent across a campaign?

Use an earlier generated post as a reference image in the next Canvas generation and prompt for the same palette, typeface style, and layout. The model carries the visual style forward. Results will have natural variation — which looks natural in a feed — but the brand feel holds.

6.Which model should I use for social media posts?

Nano Banana Pro for most posts — strong text rendering, multi-ratio output, and Studio-grade finish. GPT Image 2 is the better pick when you fuse multiple brand-library reference images or need precise instruction-following on a complex brief. Both are in the same Canvas.

7.Do I need to run ads to justify this tool?

No. The same Canvas that generates paid ad creatives works just as well for organic feed posts, Stories, and X cards. If you do run ads, see the ad generator guide for conversion-focused framing alongside the social post workflow.
