Every persona, every platform, every daily post — scheduled, then published on autopilot. Drag to explore, and pick how many phones you run.
From solo devs to multi-app studios, the story is the same: consistent content, finally.
"I shipped my app two years ago and never cracked marketing. Carousel Studio posts more consistently than I ever did, and installs finally started moving."
"We run six channels across two apps. It's the closest thing to hiring a content team without hiring anyone."
"The persona thing is wild. Same girl, every day, totally on brand. Our followers genuinely have a favorite creator and she doesn't exist."
"Pasted our website on a Tuesday. By Wednesday morning we had a carousel live with our actual app UI rendered on the last slide."
"I was quoted $4k a month by a UGC agency. Carousel Studio does the daily grind for less than my coffee budget."
From website to daily TikTok presence in four steps.
AI reads your site and drafts your brand kit: positioning, content style, and a starter creator persona.
Generate portrait options or upload your own AI face. Pick one and it's locked: the same person in every post.
Choose posting windows in your audience's timezone and connect your TikTok in two clicks.
Fresh 5-slide carousels, written, rendered, captioned, and published automatically. You watch the scoreboard.
Everything between "I should post more" and a view counter going up.
Paste your website and Carousel Studio drafts your name, positioning, and a complete content style guide. Tweak anything, or rewrite it all. Your call.
Each channel runs a face-locked AI persona. One reference portrait keeps her identical across every post, so your audience builds a relationship with a creator who never burns out.
Set 1-3 daily posting windows per channel in any timezone. Carousel Studio picks a different random minute every day and keeps channels spaced apart, so nothing looks automated.
Views, likes, comments, and shares sync automatically into a per-channel scoreboard. Double down on the creators that convert and retire the ones that don't.
See why founders pick Carousel Studio over the grind and the retainer.

Spin up AI personas tuned to your niche. Every creator is exclusive to your brand and identical in every post.
It runs your app's organic social content end to end across TikTok, Instagram, Facebook, and YouTube. It learns your brand from your website and App Store listing, invents realistic AI creator personas, and every day generates a fresh 5-slide carousel in each persona's voice — with your real app screen rendered into the final slide. That one carousel goes out as a native photo carousel on TikTok and as a vertical video (a Reel / Short) on Instagram, Facebook, and YouTube. You set it up once; it posts daily.
Exactly. TikTok loves swipeable photo carousels, so that's what it gets. Instagram, Facebook, and YouTube are video-first, so we automatically render the same five slides into a vertical short video — an Instagram and Facebook Reel and a YouTube Short — with a royalty-free music track. One piece of generated content, four native-feeling posts, no extra work.
No. The creators are AI-generated. Every image — her selfies, her day-in-the-life shots, the product, the app call-to-action slide — is generated fresh for every post, and the videos are rendered automatically from those slides. You never film, photograph, or edit anything.
Each persona has a locked reference portrait. You generate portrait options and pick your favorite, or upload your own AI-generated face. Every future post is generated against that reference, so her face, hair, and build stay consistent while the scene, outfit, and content change daily.
You connect each social account once through Zernio, our posting partner, using the platform's official sign-in — your credentials stay with the platform and we never see your password. From then on, each daily carousel fans out automatically: the photo carousel to TikTok and the rendered video to Instagram, Facebook, and YouTube, all in one go.
Every post has native-sounding audio. TikTok attaches its own recommended music to the photo carousel, and the Instagram, Facebook, and YouTube videos are rendered with a royalty-free (CC0, public-domain) track — fully cleared for commercial use, with no copyright risk.
Each persona gets a tap-tracked smart link to your App Store page that you paste into its bio once. Every tap is counted in your dashboard, so you can see exactly which persona drives the most clicks toward installs. The persona's photo, an AI-written bio, and that link all come ready in a copy-paste starter kit.
Yes. Every carousel — slides, captions, title — appears in your dashboard the moment it's generated, and you can delete anything. You control the brand prompt, each persona, and the voice, so the output style is always yours to tune. Most founders review the first week, then let it run.
Posting happens through each platform's official API, and every persona generates unique content — nothing is copied or re-uploaded across accounts, which is what duplicate-content rules target. You use real accounts you own and connect, and an optional AI-content disclosure flag is available per persona if you want posts labeled.
You just pick how many posts a day each persona makes — one, two, or three. The times are pre-optimized for reach (morning, midday, evening) and run in the persona's timezone, so there's nothing to fiddle with. One generated carousel covers all four platforms for that slot.
About ten minutes per persona: paste your App Store link and website, review the drafted brand kit, pick your creator's face, connect your social accounts, and choose how many posts a day. Your first posts can be live the same hour.
Yes — that's the whole point. Each iOS app gets its own brand kit, and you run multiple personas, each with its own face, connected accounts, and schedule. We price by the phone: one phone runs three persona accounts, and you add phones as you scale.
Views, likes, comments, shares, and smart-link taps all sync into your dashboard automatically — per post and per persona. A persona scoreboard shows which creators drive the most attention and clicks, and a projected-reach readout estimates your monthly views, so you can double down on winners.
TikTok, Instagram, Facebook, and YouTube — all four, today. TikTok gets the native photo carousel; Instagram, Facebook, and YouTube get a vertical video rendered from the same content with royalty-free music.
