From topic to scroll-stopper

The visual post — not another caption tool.

Genspark drafts the graphic at the right size for the platform, with on-brand typography and consistent style. You refine by typing — change the hook, swap the palette, tighten the CTA.

Hook · Payoff · CTA.

The post structure that earns the stop-scroll: a hook that interrupts the feed, a payoff that delivers the promise, and a CTA that tells the viewer the next move.

Brand-consistent typography and palette.

Tell the agent your colors, fonts, or upload reference images. It applies the brand across every post you generate so the feed feels like one voice, not ten.

Refine in chat. No drag-and-drop canvas.

"Make the headline louder," "shorten the hook," "swap to dark mode," "resize for Stories" — type the change, the agent updates the post in place.

Export PPTX, save as PNG or PDF for the post.

Genspark exports a clean PPTX. Save as PNG or PDF in PowerPoint, Keynote, or Google Slides, then upload directly to Instagram, LinkedIn, Facebook, or TikTok — or send the same deck as a presentation for the team to review.

Frequently Asked Questions

How does the AI generate a social media post?

Describe your topic, target platform, audience, and voice. The agent drafts a visual post — graphic, headline, body, CTA — sized natively for the platform (1:1 for Instagram and LinkedIn feed, 4:5 portrait, 9:16 for Stories and Reels). You refine by chatting.

How is this different from caption AI tools?

Caption AI writes the words. Genspark drafts the actual graphic — typography, layout, color, sized for the feed. The agent produces a visual post you can upload directly, not a paragraph of text you still need to design around.

What platforms does it support?

Instagram (1:1 feed, 4:5 portrait, 9:16 Stories and Reels), LinkedIn (1:1 feed, 4:5 portrait, document carousels), Facebook (1:1 feed, 4:5 portrait), TikTok (9:16 vertical), and X (16:9 cards). Tell the agent the platform and it sizes the canvas.

Can I keep my brand colors and fonts?

Yes. Tell the agent your color palette and font choices, or upload a reference image. It applies the brand consistently across every post you generate, so your feed reads as one voice.

Can I edit the post after generation?

Yes. Refine by typing: "bigger headline," "swap the CTA," "darker palette," "resize for LinkedIn," "add a stat." The agent rewrites and re-renders the post in place.

How do I upload the post to Instagram or LinkedIn?

Export as PPTX, then save the slides as PNG (one click in PowerPoint, Keynote, or Google Slides). Upload the PNG directly to Instagram, LinkedIn, Facebook, or TikTok like any other image post. For LinkedIn carousels, save as PDF and use the document attachment option.

Can I generate multiple variations to A/B test?

Yes. Ask the agent for 3-5 alternative hooks, headlines, or layouts and it generates them as a set. Pick the one that fits, or A/B test across audiences before committing.

Is my social media post data private?

Posts stay in your project's storage and follow Genspark's standard data handling — see our Privacy Policy for full details. You can delete the project at any time, which removes everything in it.
