What is the best AI social media post generator for product sellers?

It depends on the bottleneck. Shotova is the strongest for visual quality, generating original photographer-grade creatives around the detected product category at 1 credit per image, while Predis.ai is the strongest for workflow, bundling templates, captions, and scheduling from about $19 per month.

Can AI post generators put text on product images?

Approaches differ. Shotova renders text on the image only when the seller types it in the prompt, exactly as written, while general AI image tools like Canva's generation features have known weaknesses with text rendering, so promotions and price callouts should always be proofread on the final image.

What image sizes do Instagram product posts need in 2026?

Feed posts perform best at 4:5 portrait, stories and Reels run 9:16 vertical, and square 1:1 remains standard for grid consistency. A good generator produces all three formats from the same source photo rather than cropping one output.

What should I look for in an AI social media post generator for my shop?

Prioritize style variety, format coverage across feed, square, and story, and product fidelity, meaning the generated post shows your actual product exactly rather than an approximation. A tool with only one style or a single fixed format limits how the content actually gets used.

How much should a small seller spend on social post generation?

At per-credit pricing, three posts per week costs roughly 12 to 15 credits a month, which fits inside Shotova's $12 Starter plan alongside listing work. Subscription tools at $19 to $39 per month only pay off if their captions, scheduling, and publishing features are genuinely used.
