- social-overlaysNewhashgraph-online/awesome-codex-pluginsEleven conversion overlays for short-form ads, UGC and creator videos, with presets per platform: CTA pill, follow tap prompt, story sticker tag, LIVE badge with viewer count, notification drop, review proof card, story caption bar, photo wall loop, follower counter and goal bar, comment callout (reply-to-comment) and subscribe-and-bell nudge. Presets use one universal 9:16 safe box built from TikTok, Meta Reels, YouTube Shorts and Snap specs, CTA timing from creator analysts (ask after value, never in the intro), native number formats, contrast and motion tokens, plus the FTC rules: reviews, comments and counts come from real data only and paid content is disclosed.

- varg-unboxing-videoNewhashgraph-online/awesome-codex-pluginsTurns product photos into an unboxing or ASMR video ad on varg: hands-only, top-down or POV, the box tapped, opened and the product lifted out and switched on, with native ASMR sound (taps, crinkle, lid pop) and no music, in timed VISUAL / ACTION / SOUND blocks on Seedance 2.5 with the box and the product as references.
