Subtitle generator in seconds, no training or human needed

Generate subtitles automatically

Ever wondered how you can get around confusing tools like Premiere Pro? Subly is here for you. Premiere Pro is there for those with the time and the training. For everyone else, there’s Subly. 

Generate open or closed captions for videos automatically, in a matter of seconds. No need for big budgets or to spend time on training. Subly will do the heavy lifting, so you can focus on making any small edits and styling your video, ready to share faster with your audience. 

You wouldn’t share a video without image or sound. So why leave out the text? Subtitles can help to get the attention of those with sound off, deaf or hard of hearing. Making sure they can understand your content, whilst your engagement soars too. 

Different file types

Choose from audio or video files when uploading to Subly. Add subtitles to a video or create an audio file into a video with an image.

Over 20 languages

Select the language spoken in your video and we’ll automatically generate captions for you in seconds.

Repurpose your content

Get your video in seconds but also repurpose into VTT, SRT or TXT files so you can use it on different platforms and create blog posts and social media content.

Style your videos

Have the control to edit the font, size, position and colours of your subtitles. Add headlines to help the audience understand what the video is about and move the subtitles to the border to give your video the space it deserves.

24/7 Support

We understand that technology and content isn’t always as simple as it may seem. Subly is an easy-to-use platform, but we’re always on hand via email if you need support at any time.

How accurate is the automatic caption generator?

Subly transcription uses Artificial intelligence (AI). AI has come a long way in recent years but the accuracy is still impacted by a number of different factors.
With no background noise, a good microphone and only one person speaking at a time your subtitles will be most accurate.

Can I work on my subtitles with others and ask for approval on content?

We love to support teams to collaborate on content. Whether this is to approve a piece of work with a client or for your team to help you translate your subtitles to use around the world. You’ll need a Business plan to invite teammates to edit with you.

Can I generate subtitles on my mobile?

Subly was designed for all creators so whether you’re at your desktop or on the move, you can add subtitles to your video or audio content.

Can I make changes to the subtitles even though they’re automatic?

For sure, you’re always in control to change as much or as little as you like. We generate the subtitles for videos automatically but you can make changes to the copy and timestamps as you wish to get exactly what you want.
