Brainrotify

Brainrotify generates captioned brainrot shorts and AI lyric swaps from a topic, script or Reddit thread, exports without watermarks, and on the Business plan posts new videos to TikTok and Instagram daily.

Brainrotify is a web-based generator for short-form vertical video and audio built around internet brainrot formats. It turns a topic, a script, a Reddit thread or a PDF link into a captioned clip with gameplay footage, narration and burned-in subtitles, aimed at TikTok, YouTube Shorts and Instagram Reels. A second product line, AI Lyric Swap, rewrites the words of an eligible song and re-sings them using the original beat, melody and timing as guidance. The tool is aimed at meme creators, faceless-channel operators and social media managers who want a steady stream of shorts without opening an editor. Output modes include classic brainrot with gameplay, Reddit story narration, fake iMessage threads, text overlays, top-5 rankings, character scenes, 3D kids stories and lip-synced Italian brainrot. A swapped track can also be sent into the video engine, which produces a before and after clip showing the original line and then the new vocal. In practice a run has four stages: pick a mode, feed it a source, choose a narrator or an eligible RVC voice with captions and background, then preview and export an MP4 or MP3. Exports carry no watermark, including on the free tier. The headline feature is Autopilot, available on the Business plan, where a connected TikTok and Instagram account receives a newly generated episode on a chosen schedule, with Claude able to plan the niche. Usage is metered in credits, and most renders cost 2. A developer API accepts authenticated video and audio jobs, returns a job id, and exposes a status endpoint for polling the finished file, with credits and rate limits kept separate from the app balance. Compared with general video editors or broad AI video generators, Brainrotify is narrow by design: it covers one meme-driven genre end to end, from script to scheduled posting, and trades flexibility for speed.
