  • 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."

Questions & Answers

As answered by people managing Builder.io and Captioner.io.

What makes your product unique?

Builder.io's answer

Builder is driving the next generation of front-end programming, with the only Visual Development Platform that offers an AI-powered design-to-code tool, a visual editor, and an enterprise CMS.

What's the story behind your product?

Builder.io's answer

Our founders, Steve Sewell and Brent Locks, met on the campus of UC Berkeley in 2011, and have been friends and colleagues ever since. In those early days, they bonded over wanting to be entrepreneurs, and having lots of ideas, but not knowing how to code to bring them to life.

Fast forward more than a decade, and Steve is now a visionary technologist (Brent's words) and Brent still doesn't know how to code (beyond some basic HTML and CSS), but they continue to share a passion around building technology that can enable anyone to bring their ideas to life, which is at the core of Builder.io.

How would you describe the primary audience of your product?

Builder.io's answer

Frontend engineering leads who manage a headless site or store. Frontend and full-stack web developers whose team uses Figma to design web and app experiences

Why should a person choose your product over its competitors?

Builder.io's answer

Shipping, iterating, and optimizing high-performing digital experiences eats up a ton of time. As a result, teams donโ€™t get nearly as many experiences, pages, content, or experiments to market as they planned. Builder helps teams ship twice as much, without doubling their effort or team size. Builder does this by offering tools that optimize every step of the journey from design through optimization. No other tool comes close because they donโ€™t consider the entire journey and havenโ€™t embedded AI at the same level as Builder. As a result of shipping twice as much with the same team size, companies can significantly increase top-line revenue or decrease costs.

Who are some of the biggest customers of your product?

Builder.io's answer

  • Zapier
  • Anheuser-Busch
  • Everlane
  • JCREW
  • PetLab.co
  • Fabletics
  • Harry's
