Planoly's strength is the visual grid planner. Drag posts around, see how the next twelve squares look together, schedule from there. The image generation in Planoly is a bonus feature, not the core of the product, and it mostly assumes the user already has artwork to upload. WordPress sites that publish regularly often want the image generated from the post itself, with the post title, category, and brand applied automatically. That is a different problem.

SleekPixel handles that side. Save a post, get a 1080x1080 PNG ready for Instagram or any other square placement, alongside the standard 1200x630 OG image. The PNG lives in uploads, and the Gutenberg sidebar exposes a download button so the file is ready to feed into Planoly's planner, Buffer, or any other scheduler the team uses.

Teams keep Planoly for the grid view if it earns its keep, and use SleekPixel to make sure every square that lands in the grid is a properly branded render of the actual post. The split usually means a smaller Planoly plan and a more consistent visual presentation, because the images stop being one-off uploads and start being a function of the post.

The visual planner pattern assumes the artwork is already done. That model fits agencies and influencer brands, where the artwork is the deliverable and the planner is the staging area. For content sites, the artwork is downstream of the post, not parallel to it.

If the post headline changes, the artwork needs to change. If the category changes, the brand mark color may need to change. Those updates are easy when the artwork is generated from post data, and laborious when the artwork is a static upload sitting inside a planner.

Moving the image into WordPress lines the asset up with the source. The grid in Planoly, if it stays, is now populated with real, post-derived squares instead of generic uploads, and that consistency is what makes a brand grid feel intentional rather than busy.
