What it is
Brag reads the code of a website or app you have built and turns it into a 15 to 25 second launch video, complete with motion, music, sound effects, and ready-to-post share copy. It plans a hook, picks real screens and copy from your product, and lets you choose a tone, from polished to deadpan to fake startup parody. It is aimed at founders and makers who want to show off what they shipped without hiring a video editor.
What it does
- Reads your project to understand what the product is and what makes it special
- Writes a beat-by-beat storyboard with a strong opening hook and two or three highlights
- Renders a finished MP4 video with music and sound effects, plus a cover image
- Offers tone presets such as polished, cinematic, chaotic, deadpan, or startup parody
- Supports landscape, vertical, and square formats, with optional voiceover narration
Use it when
- You just launched a site or app and want a video to post on social media
- You need a quick product teaser without paying a video editor
- You want a vertical clip for TikTok, Reels, or Shorts showing what you built
- You want share copy written to go with your launch post
