  • 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.

"I haven't found an AI transcription software that is not only accurate but also affordable until I came across Captioner. It's a game changer for our channel."
