See whether detected text, faces, or important details collide with short-form video controls before you upload.
Check your video before the app UI covers it.
PostProof helps creators preview short-form videos with platform-style safe zones, caption checks, face checks, covers, trims, and export tools before publishing.
Draft captions and hashtags, choose a cover frame, trim start and end points, and export a platform-ready MP4.
PostProof does not require an account, does not run ads, and does not include analytics or tracking SDKs.
