Previewing and exporting your content
PrismPoster lets you preview how a post will look on each platform, then export the finished image or video as a server-rendered file. Exports come out as landscape 16:9 or portrait 9:16, and every one carries a visible AI label plus embedded machine-readable provenance metadata. Once you export, you download the file and post it yourself. PrismPoster is a content creation studio, not a publisher — it does not post, schedule, or auto-publish to social platforms. That last step is always yours.
How do per-platform previews work?
Before you export, you can preview how your content looks per platform, so you can check the framing and feel for the placement you have in mind. This is a preview of the rendered result, not a publishing connection — there's no post button to a social network. Use it to decide which crop and aspect ratio you want before you commit to the export.
What aspect ratios can I export?
You export server-rendered files in two shapes:
- Landscape 16:9 — for wide placements.
- Portrait 9:16 — for vertical, full-screen placements.
The export is rendered on the server, so the output is a finished file rather than a screen capture.
What's the AI label and provenance on my export?
Every export carries provenance on every plan. There's a visible label — "AI-generated with PrismPoster" for newly generated work, or "AI-enhanced" for edits from Magic Edit — and an always-on machine-readable mark embedded in the file (IPTC, XMP, and EXIF for images; FFmpeg metadata for video and audio; ID3 for audio). The machine mark is never gated by plan tier. This is metadata-based provenance and a visible label, aligned to EU AI Act Article 50; it is not a cryptographic C2PA signature. For why this is mandatory, see why content is labelled.
How do I post my exported content?
You download the file from PrismPoster and post it on the platform yourself. PrismPoster doesn't connect to X, Instagram, TikTok, LinkedIn, or Facebook for posting, and it has no scheduler. (Twitch and YouTube connect only for live-streamer tools, never for feed posting.) You stay in control of when and where your content goes out.
Frequently Asked Questions
Can PrismPoster post my content for me?
No. PrismPoster generates and edits content; you download the finished file and post it manually. It does not post, schedule, or auto-publish to social platforms.
Can I remove the AI label from my export?
No. The visible label and the embedded provenance mark are mandatory on every export and every plan, aligned to EU AI Act Article 50. The machine-readable mark is never gated by tier. See why content is labelled.
My export looks lower quality than the preview — what do I check?
Confirm the resolution and aspect ratio you exported at, since a crop can change perceived sharpness. For video, higher resolution costs more credits but yields more detail. See export quality issues for specifics.
