AI caption generation
Upload a video and AutoCaption transcribes the audio, generates timed captions, and applies a styled overlay so the output is ready to publish.
AutoCaption
ClaimAutoCaption is an AI caption and subtitle generator for social video. Add styled captions, export videos or SRT files, and work faster on TikTok, Instagram Reels, YouTube Shorts, and LinkedIn.
Overview
AutoCaption is an AI caption generator for short-form and social video. It takes an uploaded video, transcribes the audio, and turns it into styled captions or subtitles that can be exported as a finished video or a separate SRT file.
The product is aimed at creators and teams that want to add captions quickly without manual timing work. The site emphasizes support for TikTok, Instagram Reels, YouTube Shorts, and LinkedIn, plus multilingual transcription and translation in more than 100 languages.
Features
Custom caption styling
Use presets or build your own caption look with fonts, colors, size, position, animations, and word emphasis, then save the result as a reusable template.
Word-level subtitle editing
Edit individual words and adjust timing in a simple editor when the transcription needs correction or cleanup.
Multi-platform resizing
Auto-resize a captioned video for formats used on TikTok, Instagram Reels, YouTube Shorts, and LinkedIn, with captions repositioned automatically.
Export options
Export burned-in captions as a finished video, and generate an SRT file when a separate subtitle file is needed.
Team and API workflows
Use team collaboration and API access on supported plans to fit the tool into larger workflows.
Use Cases
Captioning social videos quickly
Publishers can upload a clip, let the tool generate captions, and export a ready-to-post video instead of handling transcription and timing manually.
Branding repeated video series
Teams can keep text, color, and animation settings consistent by saving caption templates and reusing them across recurring content.
Preparing one video for several platforms
Creators posting to multiple networks can generate and resize one upload for vertical and horizontal formats used by different platforms.
Cleaning up transcript errors
Editors who need accuracy control can fix individual words and adjust timing before exporting the final video.
Producing subtitles for mixed workflows
Channels that need a separate subtitle file can export an SRT alongside the burned-in video for platform-specific workflows.
