Tooljin › Video Caption Generator
Video caption generator for Reels, Shorts & YouTube
Drop in a video and get captions in a minute. Fix any word, give them an animated Reels look, cut a 9:16 Short from a long video, then download the captioned MP4 or an SRT file. Your video never leaves your device.
Add captions to a video in three steps
No editing app, no timeline to learn. It runs in your browser.
Drop your video
MP4, MOV, WebM or MKV from your phone or laptop. Pick the spoken language, or leave it on Auto-detect, and add any names or brand words you want spelled right.
Get captions, fix any word
Captions appear line by line with their timing. Edit them like a document: split or join lines, find and replace a word everywhere, nudge all the timing at once, undo anything.
Style it and download
Pick a caption style and animation, choose a format and an optional clip, then download the captioned MP4 or an SRT, VTT or TXT file.
Captions that look like the ones on top Reels
Five ready-made looks, any font size, colour, position and line width. What you see in the preview is exactly what ends up in the video.
Everything you need to caption a video, in one place
Hindi & Hinglish, done right
Hindi comes out in Devanagari. One click turns it into Hinglish in Roman letters, or into English, and the word timing stays in sync.
Word-by-word animation
Show one to five words at a time, highlight the word being spoken, and make captions pop, slide, glow or fill like karaoke.
Edit like a document
Press Enter to split a line and Backspace to join it. Find and replace, shift every caption with one reset button, undo and redo.
Names spelled right
Type names and brand words before you transcribe, so the speech model listens for them instead of guessing.
Shorts from long videos
Pick a part on the filmstrip timeline, switch to 9:16 and fill the frame with a blurred copy of the video, or crop to the subject.
Reels safe zone
A guide shows where Instagram and YouTube put their buttons, and warns you if a caption would be hidden behind them.
Your video stays with you
The video is never uploaded. Only a small audio track is sent to be transcribed, and the captioned video is made on your device.
Download what you need
A captioned MP4 for Reels and WhatsApp, SRT or VTT for YouTube and editors, or a plain TXT transcript.
One video, every shape
Change the frame without re-shooting. Captions are placed for the new shape automatically.
Made for Indian creators and the people who watch on mute
Reels & Shorts creators
Animated, word-by-word captions in Hindi, Hinglish or English, placed above the app's buttons.
YouTubers
Upload an SRT file so YouTube shows proper captions, or cut Shorts from your long videos.
Podcasters
Turn the best minute of an episode into a captioned clip for Instagram and WhatsApp.
Devotional & bhajan channels
Show the words of a bhajan or aarti on screen so viewers can follow along and sing.
Teachers & coaches
Captioned lessons are easier to follow, and the transcript doubles as notes.
Brands & sellers
Product videos with captions get the message across even with the sound off.

Questions about adding captions to videos
Open the tool, drop in your video, pick the spoken language (or leave it on Auto-detect) and tap Generate captions. Sign in with a free Tooljin account to transcribe. The free plan covers videos up to 10 minutes, 3 videos a month. You can fix the words, choose a style and download the captioned MP4 (with a small Tooljin mark) or a TXT transcript.
Yes. Hindi is transcribed in Devanagari, and one click converts the captions to Hinglish in Roman letters (like “aaj hum seekhenge”) while keeping the word timing, or to English. It also handles Bengali, Marathi, Tamil, Telugu, Gujarati, Punjabi, Urdu and more than 90 other languages.
No. The video stays in your browser. Only a compressed audio track is sent to be transcribed, and the captioned video is made on your own device. If you use Convert (Hinglish, English or Hindi), the caption text is sent to be rewritten.
Yes. Pick the Word pop style, or build your own: captions can pop, fade, slide up or appear word by word, and the spoken word can change colour, sit in a box, fill like karaoke, glow or bounce. You choose how many words show at once, from one word to the full line.
Yes. Pick the part you want on the filmstrip timeline, choose 9:16 and fill the frame with a blurred copy of the video or crop it. Only the clip is transcribed, so a 45-second Short from a long video costs a few credits, not the whole video. A safe-zone guide shows where the Reels and Shorts buttons will sit.
A captioned MP4 video (WebM in browsers that can't make MP4), SRT and VTT subtitle files for YouTube, Facebook and most editors, and a plain TXT transcript. Text and the MP4 with a small mark are free. SRT, VTT and a video without the mark need Pro or Business.
Accuracy is high for clear speech, and every word stays editable. Type names or brand words into the box before you transcribe and they are more likely to be spelled right. Find and replace fixes a word everywhere at once, and Shift all moves every caption earlier or later if the timing is off.
Transcription uses 4 credits per minute of audio, and only the clip if you pick one. Converting captions to Hinglish, English or Hindi uses 5 credits per 100 lines. Making the captioned video itself uses no credits, because it runs on your device. See the pricing page for plans.
Yes. It works in Chrome on Android and on laptops, and on iPhone with Safari 16.4 or newer. Long videos are faster on a laptop, and Chrome or Edge on a computer save them straight to disk.
Up to 10 minutes per video on the free plan, and up to 3 hours on Pro and Business.
