AI SRT Translator for Fast, Accurate Subtitles

Smartcat is the AI-powered enterprise language platform that helps every team move their global content faster—without adding manual work or extra headcount. Whether you’re creating marketing videos, training modules, product docs, or support materials, Smartcat blends expert-enabled AI Agents with real-time collaboration and built-in quality control so teams can produce consistent, global-ready content in one connected workspace.

AI Agents are workflow-aware automation models designed to take on the repetitive, multi-step work that slows teams down. Instead of simple “translate text” AI, Agents follow full processes: translating subtitles, syncing timing, generating voiceovers, or recreating full documents.

Smartcat’s Media Agent, for example, handles subtitle translation and dubbing end-to-end—removing the handoffs, vendor delays, and tool-switching that normally burns time and budget.

Unlike static LLMs, Smartcat AI Agents improve with your feedback, adapt to your brand rules, and stay consistent across teams. They’re increasingly used across industries to boost productivity and reduce operational friction. [1]

An SRT file (SubRip Subtitle) is a simple text file that stores subtitles: a sequence number, timecodes, and caption text. It’s widely used and easy for teams to translate, edit, and publish across any platform.

Yes. Smartcat works with SRT, VTT, and common video formats like MP4, AVI, and MOV—so you don’t have to juggle tools or convert files just to start translating.

Beyond AI-enabled translation, Smartcat connects you with vetted professional reviewers for expert refinements through the Smartcat Marketplace.

Yes. The Media Agent can generate AI voiceovers and dubbing that sound natural and consistent across languages—without waiting on studio time or external vendors. It’s a fast way to produce multilingual training, marketing, or product videos at scale.

Yes. When you need human review for high-visibility or specialized content, Smartcat connects you with vetted experts through the Smartcat Marketplace. They can refine your subtitles directly in the same workflow.

To create an SRT file, use a text editor or subtitle editing software. Enter the sequence number, start and end time codes (hours:minutes:seconds,milliseconds), then the subtitle text. Save with a .srt extension. To use the SRT file, match its name to the video file and place them in the same directory. Most video players will detect and display the subtitles automatically.

With Smartcat, you simply upload your SRT file, pick your target language, and let our AI agents provide an initial translation. Reviewers can then refine the translation within the Editor to confirm accuracy and train the AI if necessary. Once finalized, you can save and download your SRT file in the new language.

If you need subtitles embedded in a video in SRT format, extract the subtitles using video editing or subtitle extraction software. After extraction, save the subtitles as an SRT file.

Some tools let you export directly to SRT format, while others may need manual formatting to ensure proper sequence numbers, time codes, and subtitle text.

Smartcat’s AI agents combine AI translation engines, translation memories, and glossaries to deliver high-quality, consistent SRT translations. With Smartcat’s AI-human collaborative workflows, each translation benefits from AI automation and expert input, improving over time.
