Accessibility, engagement, and discoverability are extremely important factors for digital content, so much so that studies claim closed captions can lead to an 80% increase in video views. However, creating subtitles manually is a time-consuming, tedious process. Thankfully, there are AI subtitle generator tools now to streamline and simplify this important video optimization.

If you want an engaged audience, you always need to be thinking about the user experience. Video subtitles serve as the bridge to a more inclusive, captivating, and far-reaching video experience where viewers can follow exactly what’s being said. Background noise, diction, accent, or just lack of focus on the viewer’s part don’t get in the way of your video message getting through.

This blog explores why subtitles are integral to your video strategy, introduces you to the 15 best AI subtitle generator tools available in the market today, and offers tips on selecting the right AI subtitle generator tool for your video project.

Why Use Subtitles In Videos?

Subtitles may seem like a small addition to your video, but they can quickly override the more painstaking work you did to get your video out. If your audience can’t understand what you’re saying, it’s bound to impact your video’s accessibility, engagement, and discoverability. And here’s how subtitles impact those:


According to the World Health Organization (WHO), 1 in 5 of the global population suffers from hearing loss. This number is estimated to increase to almost 2.5 billion by 2050. Video subtitles are a small step towards inclusivity for those with hearing impairments, and also make sure you’re not leaving out any people who can be the target market for your products/service.

Enhanced Engagement: 

Subtitles engage viewers in noisy environments, making your content accessible even when their surroundings are not. They have been shown to boost watch time stats and make videos stand out from the crowd.

Global Reach: 

Subtitles facilitate comprehension for a global audience, breaking down language barriers. Preston Smalley, Roku’s Vice President of viewer products, supports this fact through a 2022 internal survey that revealed that 58% of subscribers use subtitles. 

SEO Benefits: 

Subtitles are important in boosting your video’s discoverability on search engines like Google, especially if these subtitles contain keywords. Search engines can better understand your video’s content and match it to user queries effectively when they detect keywords within your subtitles.

Why Use AI Subtitle Generator Tools?

Sure, you can generate subtitles manually, but then you’ll miss out on these benefits of using AI subtitle generator tools:

Enhanced Accuracy: AI-powered subtitle generators excel at transcribing spoken words accurately. This precision is particularly valuable when dealing with intricate or fast-paced content.

Time Efficiency: Creating subtitles manually is usually a tedious task. AI-powered tools drastically reduce the time and effort involved in this process. They free up valuable hours better spent on other critical aspects of video production. With some AI subtitle generators, it’s also easy to insert subtitles in different languages for variants of the same video. This feature not only cuts down on time taken but also helps you enhance your content’s reach.

Consistency Across Platforms: AI subtitle generators ensure uniformity in your subtitles, regardless of the platform your audience chooses for viewing the video. You can use the same style of captions for YouTube videos and social media ads. This consistency helps you retain your brand’s visual image and conveys a cohesive message to your audience.
