Focused on Accuracy
We don't cut corners when we transcribe your videos, we use the highest quality AI model to make sure the transcription is as accurate as possible. This saves you time and money in your content creation process.
Precise Timestamps
Not every AI transcription tool gives you timestamps precise enough for videos. We add extra processing to align the timestamps so you don't have to spend too much time tweaking them. We also provide word-level timestamps for more fine-grained controls.
Smooth Subtitle Editing Experience
Captioner is built by content creators, for content creators. We spent hours perfecting the editing experience so you can spend more time on your content and less time on the tools.
Import and Align Existing Transcripts
You might already have a transcript written for your video. No problem! You can import it directly into Captioner and we will align it for you. (Think YouTube's auto-sync feature, but better!)
Subtitle File Export
Different platforms and editing softwares use different subtitle file formats. We support the most popular formats (SBV, SRT, VTT) so you can add quickly add subtitles into your YouTube videos. You can also choose a font style directly from the editor and get a video export with the subtitles burned in.

Frequently Asked Questions
What is Captioner?

Which plan fits me?
Free includes 60 one-time credits. Basic includes 300 Monthly Credits for $10/month and clean 1080p + SRT/VTT exports. Creator includes 1,200 Monthly Credits for $20/month, full subtitle styling, 4K, and priority rendering. Weekly Pass is a $7 one-time payment for 120 Permanent Credits and 7 days of Creator features.
How much does it cost?
Free costs $0. Basic costs $10/month or $60/year, and Creator costs $20/month or $120/year; yearly billing saves 50%. Weekly Pass costs $7 once. After its 7-day Creator window, unused Permanent Credits stay available with clean 1080p + SRT/VTT exports while they last.
Can I upload large files?
While you can submit videos up to 2 hours long, the file size limit is currently at 2GB. If you have a larger file, you can shrink it to a smaller resolution (480p) and compress it before uploading, and edit the subtitles on Captioner first, then export the subtitles in SRT / VTT format and import them to your video editing software before rendering.
What video formats do you support?
Captioner currently supports MP4 and MOV file uploads. We recommend using MP4 files for the best results. If you have a different format, you can convert it to MP4 using a free online converter.
How long does it take to transcribe a video?
We are not the fastest because we optimize for accuracy so you don't have to spend too much time editing afterwards. But for an average 30-minute video, it usually takes around 5-6 minutes to transcribe.
How long does it take to render a video?
Rendering a video is the most time consuming step in the process. Usually for a 5-minute video, it takes about 5-10 minutes to render.
The processing is taking too long! I have waited for more than 30 minutes!
I apologize for the delay. Please feel free to reach out to us by using the chat bubble on the bottom right on the dashboard, we will be happy to help you speed up.
What formats can I export the subtitles in?
You can export the subtitles in SBV, SRT and VTT formats. These are the most common formats that are supported by most video editing software.
What languages do you support?
Captioner converts speech to text in over 98 languages using the highest accuracy AI transcription technology. Languages like English and Chinese are most accurate, and we have specifically fine-tuned our Whisper model to support Cantonese, a dialect of Chinese. However, Voice to text accuracy varies by language. Do feel free to try it out and see if it meets your needs. You can check out the full list of supported languages in the documentation.
What languages do you offer translations?
Captioner supports subtitle translation to Chinese, Spanish, Burmese, Portuguese, French, Indonesian, Russian, Arabic, Vietnamese, Polish, Italian, Turkish, Hindi, German, and Thai, alongside existing English, Japanese, and Korean options in the editor.
Can I edit the subtitles?
Yes. After transcription, you can edit subtitle text and timing directly in Captioner, then export the result. Creator and an active Weekly Pass also include full subtitle styling.
Do I need to mute the background music in my video?
Even though it is best to have a clean speech audio for the best transcription results, you don't have to mute the background music in your video. Captioner is designed to transcribe speech even with background noise, because we have a built-in voice extraction process that can separate the speech from the background noise. This ensures that the subtitles are as accurate as possible.
How do I cancel the subscription?
You can cancel your subscription at any time by clicking "Billing" in the dashboard. You'll have full access to Captioner through the end of the current billing period.
Who is behind Captioner?
Hey! I am Simon. I spent over a decade building AI systems at companies like Amazon. Now I'm building products and services like Captioner.
