Adding captions to your videos used to mean hours of manual typing, expensive software, or paying a professional service. Today, it takes under 60 seconds — for free. Here's exactly how.
Step 1 — Open Capllio's free editor
Go to Capllio's Subtitle Generator. No account is required. No software to install. It runs entirely in your browser.
Step 2 — Upload your video
Click the video panel and select your file. Capllio supports MP4, MOV, AVI, MKV, and WEBM, with no size or length limits. Your video is never uploaded to our servers — only the audio is sent for processing.
Step 3 — Select your language (optional)
For best accuracy, select the language spoken in your video from the dropdown. You can also leave it on Auto-detect and Capllio's AI will identify the language automatically.
Step 4 — Wait for transcription
Our AI engine processes your video in real time. Typically 15 to 60 seconds depending on length. You can watch a live preview of captions appearing in the transcript panel as it works.
Step 5 — Download your SRT
Click "Download SRT". Your file downloads immediately with precise timestamps for every caption line — free, with no ads or watermark.
Step 6 — Upload to your platform
YouTube: YouTube Studio → your video → Subtitles → Add → Upload file.
TikTok: During upload, tap "Captions" → Upload SRT.
Instagram Reels: Upload flow → Captions → Upload.
Adobe Premiere: File → Import → find your SRT → drag to timeline.
That's it. Accurate, timestamped captions on every platform in under two minutes total.
