Reelflex

AI ad generator: paste a product's URL and get a finished video ad. A headless browser reads the site first, its brand colors, fonts, headlines, logo and real product screenshots, then you pick one of four formats: a straight explainer, a direct roast with gag pills, a character monologue, or an App Moment, a vertical ad where a phone walks through real app screens. Claude writes the script and the brand sheet from what the site actually says, beat by beat and with no invented numbers, and writes it natively when the ad is not in English; every line can be edited before anything renders. ElevenLabs performs the voiceover with acted delivery (v3) and composes the music, optional generated b-roll fills the scenes, and Remotion cuts it all into one video. Built on Next.js with Firebase Auth and Firestore, with the ingest and render engines running as separate Cloud Run services behind bearer tokens, a guard that refuses internal addresses on every URL, finished ads kept private in Cloud Storage behind signed links for their owner, and a per-user daily cap so the private beta cannot run up a bill. In private beta, not open to the public yet.
