About this tool
What is the AI Subtitle Generator?
AI Subtitle Generator is a free, browser-based audio utility for video editors, educators, podcasters, and social media teams. Use it to turn a timestamped transcript into readable SRT or WebVTT caption text. Start with an accurate transcript with timestamps or clear timing cues; LiteTools gives you editable caption blocks ready to validate against the media. There is no account wall, so you can open the page and begin immediately.
The workspace is designed for a focused task instead of a complicated editing suite. Play the captions with the final video and correct names, timing, line breaks, and speaker changes. The page explains the result before you download or copy it, helping you decide whether it fits your final workflow. Browser processing is used where the tool supports it; AI-assisted tools clearly identify when a request may be sent to the selected model provider.
