I APOLOGIZE FOR THE INCONVENIENCE
Problem
Most captioning tools either make you upload your videos to the cloud, charge a subscription, or generate subtitle files without helping you turn them into finished videos.
I wanted something simple: drop in a video or entire folder and get back finished videos with social media style captions already burned in.
Caption Comet is a native Apple Silicon Mac app that handles the complete workflow locally. It includes bundled Whisper models, so there are no models to download separately, no account, no API key, no subscription, and no cloud processing.
It supports:
• Word-level text and timing editing
• Customizable burned captions
• Word by word and karaoke highlighting
• SRT, VTT, ASS, TXT, and MKV softsub exports
• Batch processing
• Configurable Dock Drop targets
• Imported subtitle files
• Caption timing adjustment
Quick Mode can process a folder containing videos with different codecs, aspect ratios, resolutions, and containers, then return them with captions already burned in using your chosen style.
For more control, Project Mode provides a detailed editor where you can correct spelling, adjust individual word timing, or shift an entire subtitle track earlier or later to fix synchronization.
Dock Drop workflows can be configured for anything from automatic transcription and burned video export to batch subtitle generation for later review.
Caption Comet supports the 99 languages available in Whisper Large v3, runs on Apple Silicon Macs with as little as 8 GB of memory, and can translate supported languages into English.
Comparison
• veed - monthly recurring costs, credit based monthly limits, you have to upload your videos for cloud processing.
• Macwhisper - focuses on transcription and subtitle export. Caption Comet also includes tools for styling and burning captions directly into finished videos.
Pricing
The free version includes the full transcription, editing, and batch-processing workflow. Exports are limited to the first 30 seconds, and burned-video exports include a small Caption Comet watermark.
Pro removes all restrictions.
Includes a free 30-day Pro trial.
Lifetime Pro: $14.99 launch special (regular price will be higher)

the local batch workflow is the strongest angle here. i'd make the export behavior really obvious on the page: burned-in mp4 only, srt/vtt sidecar, or both. people doing shorts/reels usually want burned-in captions, but anyone editing longer videos will care a lot about being able to fix timing/text in a separate subtitle file before final export.
Right now it’s basically checking or unchecking a box for each of those (the txt, srt, vtt and ass files are checked by default), the burned one isn’t to draw attention to picking a template or configuring the look, though maybe I should default that one to selected too. But yeah, batching was probably my main focus, still trying to decide what I should have selected and deselected by default
i would leave burned-in off by default unless the user picked a visual template already. sidecar files are safer as the default because they do not destroy the original video and people can still fix timing later. maybe make the first-run choice very plain: 'editing workflow' = srt/vtt/ass checked, 'ready to post' = burned mp4 checked. that maps better to intent than trying to pick one universal default.
I mean exporting the burned subs won't destroy the original, it burns them into a separate copy, but you're right about using different default workflows for different types of workflows
yeah, that makes sense. i'd phrase it as 'export a new rendered copy' everywhere, because 'burned in' sounds destructive to non-video people. the safer default might be sidecar srt/vtt plus an obvious 'render captions into a copy' button. that keeps editors safe while still making the shorts workflow one click.
That’s a good point. I’ll make it clearer that it always creates a new copy and never modifies the original. Thanks!
Love the fact that it's local. definitely gonna use. Any future plans to integrate to premiere?
Thanks! What kind of Premiere integration are you thinking of? Right now Caption Comet can export editor-friendly subtitle formats (SRT, VTT, ASS), so you can import them into Premiere. I’m interested in making workflows smoother though.
It might sound lazy, but if I could just have a plugin that generates the captions right in Premiere, that’d be awesome.
Not lazy at all. The whole point of good software is to eliminate as much work as possible. I like the idea. I can't promise a timeline, but it's definitely something I'll be looking into. The interest in Premiere integration is really helpful feedback. Thanks!
