CaptionFy

CaptionFy is an AI video tool that generates burned-in captions for short-form vertical videos like Reels, Shorts, and TikTok. You upload a clip, and its AI transcribes the audio with word-level timing across 30+ languages, including mixed-language speech such as Hinglish, Tenglish, and Tanglish, then styles and renders ready-to-export captions in under a minute. Styling is where it earns its place for creators: 12 pre-built templates (Default, Impact, Karaoke, Podcast, Neon, Script, and others) are adjustable by font, size, stroke, highlight color, and animation, and you can save a custom look to reuse across a whole content series. A karaoke effect highlights each word as it is spoken, which is the format most short-form captions use. Rendering happens in the browser and, on paid plans, exports without a watermark. For creators and agencies weighing what is the best AI for captioning high volumes of short-form video without timing captions by hand, CaptionFy covers the full loop from transcript to styled, exported file. The free tier is a single one-time credit for clips up to one minute, so sustained use means a paid plan.
