Captions Generator
AI captions and subtitles timed to every word, with no sign-up
About Captions Generator
Captions Generator is a browser-based AI caption and subtitle tool. You drop in a video, an audio file or an existing SRT, the AI transcribes the speech in any of 100 languages and times each word to the audio, and you export either a video with the captions burned in or subtitle files for another editor. It removes the two slow parts of captioning short-form and long-form video: typing or correcting a transcript by hand, and styling animated captions so they look like the ones people see on TikTok and Reels.
The free plan needs no sign-up and covers videos up to 30 minutes in 1080p with a small watermark, plus SRT, VTT and TXT downloads and translation into more than 100 languages. The site publishes its own speed and accuracy comparisons against CapCut, VEED, Descript and others, with the test clips and results posted on GitHub; it reports about 94% of words right on deliberately hard audio and over 99% on clear speech. Pro removes the watermark, raises the limit to 90-minute videos and 4K, and unlocks every style; it is $6.99 a month on a limited-time offer against a $9.99 list price, or $59 billed yearly.
First you upload a file: MP4, MOV, MKV, MP3, WAV or an SRT you already have. The AI detects the language automatically, including English and Chinese mixed in one sentence, transcribes the speech and times each word so captions appear exactly when they are spoken.
Second you edit and style. You can fix any word in the transcript, pick one of the ready-made caption styles, set fonts, colors, outline, background and position, add up to three hook titles on screen, or translate the subtitles into another language. What you see in the preview is what you export.
Third you export. You can download the captioned MP4 with the captions burned in, or SRT, VTT and TXT files for YouTube, Premiere, CapCut or any other editor. The site states that your video never leaves your device.
- •Word-Timed AI Transcription - Speech is turned into text in 100 languages with automatic language detection, and every word is timed to the audio. You can correct any word or import your own SRT instead.
- •Caption Styles and Word Animations - Eight styles are free and 22 come with Pro, including karaoke, word highlight, bounce, word box and one-word-at-a-time animations, with AI keyword highlights on Pro.
- •Copy a Style From a Screenshot - Drop a screenshot of captions you like and the tool matches the font, size, colors, outline, shadow and position, then previews them on your own video.
- •Hook Titles and Safe Zones - Add up to three on-screen texts, such as a title for the first seconds, with a safe-zone check for TikTok, Reels and Shorts so captions are not hidden behind the app interface.
- •Translation and Bilingual Captions - Translate captions or your own subtitle files into 100+ languages for free, including right-to-left scripts, and show two languages at once on Pro.
- •Burn-In or Subtitle Files - Export an MP4 in 1080p for free or up to 4K on Pro, or download SRT, VTT and TXT files for other editors and platforms.
Short-form creators on TikTok, Instagram Reels and YouTube Shorts can add animated, on-brand captions in minutes, copy a caption look they have seen elsewhere, and keep text inside each platform''s safe zone. YouTubers and podcasters publishing longer videos can generate accurate SRT files to upload alongside the video, which also helps viewers who watch with the sound off.
Educators, course creators and teams publishing training or meeting recordings can make their videos accessible to deaf and hard-of-hearing viewers, and translate subtitles for learners abroad or show bilingual captions. Marketers and agencies captioning ad creative and UGC can work without installing software or creating an account for one-off jobs, then move to Pro when they need watermark-free 4K exports, longer videos and the full style library.
