After FrameCheck runs, a ranked panel shows which of the 10 layouts is cleanest for your specific clip — fewest covered regions, best duration fit, native aspect match — with a plain-English reason and a one-tap switch. No more reading all 10 chips manually.
Check your video before the feed UI covers it.
PostProof previews short-form videos with pixel-accurate safe zones, a best-layout recommender, a cover frame scrubber, offline hashtag presets, a caption studio, a specs cheat sheet, explainable scores, a Stop Score trend chart, and a saved-proofs history with side-by-side compare mode. Fully offline, with generic layout names and no platform brands.
A full-range time slider lets you pull any exact frame from the clip as your cover, not just the auto-sampled picks. PostProof extracts it on-device, scores it with the same sharpness, contrast, and face-detection pipeline, and previews it with a score pill.
10 bundled hashtag sets by creator category — Education, Comedy, Lifestyle, Beauty, Fitness, Food, Tech, Travel, Music, Creator Growth — 80 tags total. Tap a category, then Add (merge, no duplicates) or Replace into your draft.
Exact per-edge margins for 10 generic layouts (Tall-Caption Vertical, Right-Rail Vertical, Title-Bar Vertical, Square Timeline, and more), stored as real pixels on each canvas.
See whether detected text, faces, or details collide with the feed controls, with a true coverage percentage per region instead of a binary pass or fail.
Place a 3 to 7 word caption card that snaps inside the center-safe area, with a contrast check so it stays readable, sound on or off.
Tap any score, Stop, muted readability, or loop, to see exactly which credits and deductions produced the number.
A bundled cheat sheet of aspect, durations, resolution, bitrate, and frame rate per layout, plus a caption library and glossary.
Save each run locally to track improvement. No account, no ads, no analytics, no tracking, no in-app purchases.
The Proofs tab shows a live line chart of your Stop Score across your last 20 saved proofs, with a rolling average reference line and Latest / Best / Avg stat pills.
Long-press any saved proof to pick a second one and see a side-by-side comparison with exact deltas and winner indicators for every metric.
Tap any row in Proofs for a full detail view: score bar, metric tiles, your saved caption with one-tap copy, cover-time, and a copyable breakdown text.
