AutoCaption

AutoCaption generates animated, multilingual captions for short-form video in seconds. It offers a timeline editor for timing, reusable brand templates, auto-resize for TikTok, Reels, Shorts, and LinkedIn, plus direct publishing, aimed at creators and small teams.

AutoCaption is an AI-powered caption generator built for short-form video creators. It automatically transcribes speech and renders styled, animated captions on top of the footage, targeting the vertical formats used by TikTok, Instagram Reels, and YouTube Shorts. The tool handles transcription and translation in more than 100 languages and accepts all major video formats up to 4K resolution. Most clips are captioned in under 10 seconds, with longer videos typically finishing in a few minutes. In practice, the workflow is upload, style, export. After dragging in a file, creators pick a caption preset or build one from scratch: fonts, colors, size, position, word emphasis, and animation are all adjustable, and settings can be saved as reusable templates. A timeline editor allows word-level text corrections and timing adjustments. From there, the video can be exported in high quality or published directly to TikTok, Reels, or Shorts without leaving the app. Auto-resize handles the aspect ratio changes needed for 9:16 vertical platforms and for LinkedIn's 1:1 or 16:9 formats. The tool suits individual creators who post frequently and need to keep captions consistent, as well as small teams that want shared projects, saved brand presets, and API access for automated workflows. It also works for repurposing longer content into platform-specific cuts. AutoCaption positions itself as a caption-first tool rather than a general video editor. Its comparison pages contrast it with Submagic and Kapwing, the latter being a broader editing suite where captions are one feature among many. For creators whose main need is fast, stylish, multilingual captions and direct publishing, AutoCaption covers that path end to end. The free tier allows testing without a credit card, while paid plans unlock higher export quality, more templates, and team features.
