How to use — the complete guide
AI Caption Generator adds Hinglish or English captions to your video automatically — no app to install, one free Google sign-in, and no upload. Here is every step in plain words.
1. Pick a video
On the home page tap “🎬 Pick a video” and choose a video from your gallery. MP4 works best. Videos up to 10 minutes are supported right now.
💡 For the best results: clear voice, phone close to the speaker, and little background music. Videos with songs may get some words wrong.
2. Choose the caption language and a template
- Hinglish: for videos where people speak Hindi — captions come in Roman letters, like “aaj hum baat karenge”. The most popular style on Reels.
- English: for videos where people speak English — English captions, like “today we will talk about this”. (The English model is a one-time ~40 MB download.)
Then pick any of the 165+ templates — 🔥 Trending, Reels Viral, Desi, Gaming, 3D and more. You can change it later. Tap ♡ on a template to save it in ⭐ Favourites.
3. Tap “✨ Create captions”
The first time, the AI model for the chosen language (~40–44 MB) downloads — only once; after that it stays saved on your phone. Then captions are created from your video's audio. Everything runs inside your phone, so keep the screen on.
4. Place the caption anywhere with your finger
- In the preview, press and hold on the caption for half a second — the phone vibrates lightly and a dotted box appears around the caption.
- Now move your finger — take the caption to the top, bottom, side, anywhere.
- Lift your finger — the position is saved and the exported video uses it too.
- Pinch with two fingers to make the caption bigger or smaller, or use Edit → 📐 Size.
For quick placement there are also ⬆ Top / ⏺ Middle / ⬇ Bottom buttons.
5. Edit: style, filter, text
- 🎨 Style: change the template or switch Hinglish/हिंदी.
- 🌈 Filter: 20+ looks like Cinematic, Warm, Vintage and Moody, plus Brightness/Contrast/Saturation sliders.
- 📐 Size: size, position and how many words show at once (1–5).
- ✏️ Text: fix wrong words. You can also tap the caption in the preview to edit it.
6. Save (download MP4)
Tap ⬇ Save. The video is made in real time — a 1-minute video takes about a minute. Then Download it or Share it straight to WhatsApp/Instagram. Most Android Chrome versions create MP4; if your phone can't, it creates WebM (which also works on Instagram/YouTube).
Having a problem?
- Model didn't download: check your internet, try Wi-Fi.
- No words appeared: is the voice clear? Try with less music.
- Phone is slow: close other apps. The 3D effect switches off automatically on older phones.
- A red “What happened” box appeared: take a screenshot and send it to us from the Contact page.
Kaise use karein — poora guide
AI Caption Generator se aap apni video par Hinglish ya English captions apne aap bana sakte ho — bina app install kiye, ek free Google sign-in ke saath, aur bina video upload kiye. Neeche har step simple bhasha mein hai.
1. Video chuno
Home page par “🎬 Video chuno” dabao aur gallery se video select karo. MP4 video sabse achha chalta hai. Abhi 10 minute tak ki video support hai.
💡 Best result ke liye: saaf awaaz, mic paas mein, aur background music kam. Gaane wali video mein shabd galat aa sakte hain.
2. Caption language aur template chuno
- Hinglish: video mein Hindi boli gayi ho to captions Roman letters mein aate hain, jaise “aaj hum baat karenge” — Reels ke liye sabse popular.
- English: video mein English boli gayi ho to English captions, jaise “today we will talk about this”. (English model pehli baar ~40 MB download hota hai.)
Phir 165+ templates mein se koi bhi chuno — 🔥 Trending, Reels Viral, Desi, Gaming, 3D… Template baad mein bhi badal sakte ho. Kisi template pe ♡ dabao to wo ⭐ Favourites mein save ho jaata hai.
3. “✨ Captions banao” dabao
Pehli baar chuni hui language ka AI model (~40–44 MB) download hota hai — ye sirf ek baar hota hai, phir phone mein save rehta hai. Uske baad aapki video ki awaaz se captions bante hain. Ye sab aapke phone ke andar hota hai, isliye screen on rakhein.
4. Caption ko ungli se kahin bhi set karo
- Preview mein caption ke upar ungli 0.5 second dabake rakho — phone halka sa vibrate karega aur caption ke chaaron taraf dotted box aa jayega.
- Ab ungli ghumao — caption upar, neeche, side, kahin bhi le jao.
- Ungli hatao — jagah save. Export mein bhi wahi jagah aayegi.
- Do ungli se pinch karke caption chhota-bada karo, ya Edit → 📐 Size slider use karo.
Jaldi ke liye neeche ⬆ Upar / ⏺ Beech / ⬇ Neeche buttons bhi hain.
5. Edit: style, filter, text
- 🎨 Style: template badlo, Hinglish/हिंदी badlo.
- 🌈 Filter: Cinematic, Warm, Vintage, Moody jaise 20+ looks, aur Brightness/Contrast/Saturation sliders.
- 📐 Size: size, jagah, aur ek baar mein kitne shabd dikhein (1–5).
- ✏️ Text: galat shabd theek karo. Preview mein caption pe seedha tap karke bhi edit kar sakte ho.
6. Save (MP4 download)
⬇ Save dabao. Video real-time mein banti hai — 1 minute ki video ko lagbhag 1 minute lagta hai. Phir Download ya Share karke seedha WhatsApp/Instagram pe bhejo. Zyadatar Android Chrome MP4 banata hai; agar aapka phone MP4 support nahi karta to WebM banegi (wo bhi Instagram/YouTube pe chalti hai).
Problem aa rahi hai?
- Model download nahi hua: internet check karo, Wi-Fi pe try karo.
- Koi shabd nahi aaya: video mein awaaz saaf hai? Music kam karke try karo.
- Phone slow: dusre apps band karo. 3D effect apne aap band ho jaata hai purane phones pe.
