Riffkit

No and yes. Riffkit never re-uploads the source clip; it studies the structure (hook, pacing, beats) and generates completely new footage with your story, product and character. You bring the product and soundtrack, so the rights to what you publish stay yours.

Yes, AI-made video runs as organic posts and paid ads on both platforms. The requirement is to tag videos featuring realistic AI-generated people with the platform's built-in AI-content label; original footage you own goes through the same ad review as any other creative.

Yes. Riffs render 9:16 by default and post natively to TikTok, Instagram Reels and YouTube Shorts, and 1:1, 4:5, 3:4 or landscape ratios can be picked at generation. To start from a Reel or Short you upload the video file; paste-a-link input supports TikTok URLs.

Yes. Any finished video can be reframed into 3:4, 1:1 or 4:5 for Feed and other placements, near frame-identical with only the framing shifted. Each ratio is its own render, billed per second at the reframe rate shown on the pricing page.

Yes. You add a product image, a physical item or a screen from your app, and Riffkit weaves it into the story the formula calls for rather than placing it on a generic stock avatar.

A consistent character you define, which can be you: upload a reference photo, write a persona, and that character stars across every riff. Auto mode casts a character for you if you prefer not to manage one; Riffkit will not put someone else's face in your video.

Yes. Adding a short voice sample of 4 to 15 seconds of clean speech to a character makes that character speak in your voice, keeping one recognizable voice across videos and languages.

Locking the same character and product across riffs keeps one recognizable face, voice and cast, while each video's footage is generated fresh, so the series is consistent but not repetitive.

Yes, described as the fastest way to find out who actually buys: create a character per audience and pair each with a creative direction, then riff the same winning formula across all of them for a batch of tests in an afternoon.

Yes. Riffkit generates natively in 9 languages, with native phrasing, the right fonts, and captions aligned to the spoken audio rather than a translated caption layered on top.
