Best AI Tools for Subtitles
There are different AI algorithms out there, some of which have been optimized for speech-to-text.
To be fair, this capability has existed for years, with AI only making it better.
For instance, modern AI speech-to-text tools can distinguish between multiple languages, dialects, and accents and will be able to handle it all.
As such, these tools have found their use among folks looking to add subtitles to their videos, as well as those looking to create short clips for platforms such as TikTok, Instagram Reels, and YouTube Shorts.
Here are some of the best tools for adding subtitles to your videos:
vidby
- Probably the best service for video translations
- Includes both AI and actor voices
- Telegram bot can be really handy
- Somewhat complicated pricing
vidby is an AI-powered software for rapid and accurate video and document translation, subtitling, and dubbing.
Unlike traditional services, it is automated and available 24/7 from all around the world, yet a thousand times faster and ten times more cost-effective.
While it can “handle” documents, vidby is primarily made for transcribing and translating videos — allowing organizations of all sizes to make their message easy to understand to the global audience.
And it’s not just a phrase, with the service being used by more than 2,000 companies in over 70 countries. Among vidby’s partners and clients are such well-known brands as Harvard University, Google, European Parliament, Samsung, Microsoft, Amazon, GE, and Axel Springer.
What’s more, the service has been recognized as a recommended vendor by YouTube. And that has to count for something, right?
Opus Clip
- Talk about content repurposing
- It's a true time saver for creating short videos
- Helps everyone master TikTok, Instagram Reels and YouTube Shorts
- Limited customization options (not necessarily a deal breaker)
Opus Clip is a generative AI video tool that repurposes long talking videos into shorts in one click — creating 10 viral clips from a single long video.
The service lets you gain new followers on platforms like TikTok and YouTube, and consequently increase website visitors.
It leverages big data to analyze your video content in relation to the latest social media trends from major platforms, and generates a comprehensive understanding of your video for a data-driven decision on content repurposing. Opus Clip then picks the highlighting moments of your long video, rearranges them into a viral-worthy short and polishes it with captions, AI layout, smooth transition to ensure that the clip is coherent and attention-grabbing, and ends with a call-to-action.
The tool will even highlight keywords and add emojis, which are the two tactics that have proven to work with short viral videos.
We can’t recommend it enough; you should try Opus Clip for yourself and see why it is being used by more than 1 million creators. Simply put – it works. Check it out.
Kapwing
- Allowing anyone to create videos is cool
- You don't even need a text to get started - you can generate it with GPT
- Perfect for everyone looking to expand its social media reach
- It can take some time to get used to Kapwing's interface
Kapwing’s AI Video Editor is an online tool that turns text prompts, scripts, or images into fully edited videos with B-roll, voiceovers, and subtitles in minutes. It utilizes AI models such as MiniMax and Pika to generate content, supporting resolutions up to 1080p and aspect ratios like 9:16 and 16:9, for platforms like TikTok and YouTube. The platform is built for speed, automating tasks such as resizing, subtitling, and trimming, making it accessible to both beginners and professionals alike.
The workflow is simple. Enter a prompt or script, and the AI creates a video with visuals, music, and captions. Trim with Transcript lets you edit by modifying text, while Smart Cut removes filler words and pauses automatically. The AI Assistant refines prompts to ensure better results. Collaborative features, such as shared workspaces and real-time commenting, enable teams to work together seamlessly. This is a strength not fully matched by competitors like Descript, which focuses on audio editing.
Compared to Veed, Kapwing offers more robust video generation and collaboration tools. However, Veed’s interface is slightly more polished. InVideo is another rival, strong for quick edits but weaker in team features. Kapwing’s free plan includes a watermark, which can be removed with a paid plan. Its credit-based AI system is flexible but may limit usage for heavy users. Pricing aligns with that of similar tools on the market.
Key features include Background Remover, which strips backgrounds in seconds, and Auto-subtitles, which generate captions in multiple languages with good accuracy. AI Clip Maker creates short clips for social media, ideal for highlights. However, AI-generated B-roll can sometimes feel mismatched, requiring manual tweaks. Translation tools are reliable but may require minor corrections for less commonly spoken languages. The cloud-based platform works across devices, including mobile, with no downloads needed.
Kapwing excels for creators who need fast, platform-ready content, but may not suit those requiring advanced manual controls, such as Adobe Premiere Pro. The credit system can feel restrictive for high-volume users, and the watermark on free exports may deter some. Still, its ability to automate tedious tasks makes it a strong choice for efficient video production.
For best results, use clear prompts and lean on the AI Assistant for guidance. Test Smart Cut for dialogue-heavy videos and AI Clip Maker for social media clips. Verify translations before publishing, and use collaborative tools for team projects. Kapwing’s ease of use and speed make it a solid choice for creators who prioritize efficiency and productivity.

LALAL.AI by OmniSale
- Allows everyone to play with music source separation
- Professional-level results with little effort
- LALAL.AI can process up to 20 files at once
- It could be a bit complex for true beginners
LALAL.AI is an AI-powered tool that separates audio and video files into vocals, instruments, and specific stems, such as drums or piano, with high precision. Built on transformer-based neural networks like Phoenix and Perseus, it processes files fast, delivering clean stems in seconds. You can upload MP3, WAV, FLAC, or even MP4 files, choose your stem type, and tweak settings like Enhanced Processing or Noise Canceling Level for tailored results. It is a go-to for musicians, podcasters, and video editors needing isolated audio tracks.
The tool offers 10 stem separation types, including vocals, drums, bass, piano, and guitars, far surpassing competitors like Moises, which focuses on fewer stems, or VocalRemover, which sticks to basic vocal extraction. The Enhanced Processing feature, with Clear Cut and Deep Extraction modes, lets you control bleed between stems. Clear Cut minimizes overlap for cleaner output, while Deep Extraction captures more detail but risks some bleed. The De-Echo feature is a standout, reducing reverb in vocals for a polished sound.
Pricing is minute-based, with options like Lite (90 minutes) and Plus (500 minutes), offering flexibility without an expiration date. The free Starter pack processes 10 minutes but restricts downloads, which may disappoint casual users. Compared to Moises’ subscription model, LALAL.AI’s pay-per-minute system suits irregular users, although heavy users might find it costly, as a 5-minute track with three stem types deducts 15 minutes. Batch processing and API access add value for professionals.
The interface is straightforward, featuring a preview option that allows you to check stem quality before complete processing, saving time and effort. Supported formats are robust, including MP3, WAV, FLAC, MP4, AVI, and, for premium users, the option to choose output formats. However, complex mixes with overlapping sounds can lead to minor artifacts. High-bitrate files, such as 320 kbps or lossless, yield the best results, and the preview step helps avoid wasting time on poor inputs.
Cross-platform support, including a desktop app and API, makes it versatile for creators on the move. Video file support is a unique edge, letting users extract audio from MP4 or AVI files, unlike Moises or VocalRemover, the Noise Canceling Level, Mild, Normal, Aggressive, helps clean up background noise, especially for voice recordings.
For optimal use, upload high-quality files and use the preview to assess stem quality. Experiment with neural network settings, Phoenix, Orion, and Perseus, to find the best fit for your audio. If you are splitting multiple stems, track your minute usage to avoid running out mid-project. Start with the Lite pack to test the waters, and consider the Plus pack for larger projects or frequent use.
What can AI tools for subtitles do?
These tools are made to help anyone add subtitles to their videos with ease. They rely on speech-to-text technology that has further been enhanced with AI to better understand spoken language. Here’s what they can do for you:
-
Automatically generate subtitles
The process of preparing subtitles used to take hours, and now it’s mere minutes, if not seconds. An AI tool can go through the video and automatically generate subtitles for your clips. You may then decide to check for the “quality” of the language, all while saving up to 95% of the time.
-
Multi-language support
These tools are no longer “stuck” to English as they can also understand many other languages. In fact, we have seen some tools offering subtitle generation in more than 100 languages – even promising to distinguish between multiple dialects.
-
Special text effects
You have probably seen videos, especially short ones, that emphasize certain keywords in their subtitles. This is because the video producer decided to do that in order to highlight certain points that have been proven to work (drive engagement and clicks). AI can help you with that, as well.
-
For short and long videos alike
We’ve mentioned short videos above; well, these AI tools for subtitles can be used both with short and long clips. In the former case, they will help video creators generate fancy subtitles that include word highlights to make these clips easier to digest across platforms like TikTok, YouTube Shorts, and Instagram Reels.
-
TikTokers love it
Finally, and related to the previous point, TikTokers love these tools – and the same goes for folks publishing videos on related platforms (YouTube Shorts and Instagram Reels). Fancy subtitles make their clips easier to grasp and more engaging – thus leading to more clicks.
As you have seen, AI is pretty much essential for generating subtitles. Whether you need to do that for a short or a long video, there is a tool to help you out. You just have to try one of the tools from this page…
