Drop your video
MP4, MOV or WebM from your phone or editor. It opens inside your browser and is never uploaded anywhere.
AI writes every word
Whisper speech recognition runs on your own device and times each word. Fix any word by clicking it.
Pick a style, export
Download an MP4 ready for posting, SRT and VTT subtitles, or animated captions for After Effects and Premiere Pro.
Write it. We turn it into a video.
Pick AI Images, Stock Videos or Animated. Every sentence becomes a scene, an AI voice reads it, trendy transitions like whip pans, zoom punches and light leaks join the scenes, and the captions animate word by word. Then fine-tune it all in a real timeline editor and export an MP4.
Honest note on AI video
Fully AI-generated footage (models like Wan or LTX-Video) needs big graphics servers, so nobody can offer it free and unlimited. BolCaps makes your video from free AI images with camera motion, free stock clips from Pexels, Pixabay and Wikimedia Commons, and your own clips, all on your device. For one real AI shot, make it with a free Hugging Face demo (daily limit) and drop it into a scene.
Cut, clip, voice and post, all in one editor.

Good to know
Is my video uploaded to a server?
No. The video, the speech recognition and the export all run inside your browser. Only the AI model files are downloaded the first time, and your browser keeps them for next time.
How accurate are Urdu and Hindi captions?
Choose the Accurate model for Urdu and Hindi. It gets clear speech mostly right; strong background music or fast slang can cause mistakes. Every word can be edited before you export.
Which browser works best?
Chrome or Edge on a laptop or desktop is fastest because they support WebGPU. Phones and Safari work too, with slower transcription.
How do the After Effects and Premiere Pro exports work?
For After Effects you download a script and run it from File › Scripts; it builds the animated captions as editable layers. For Premiere Pro you install the free Bridge panel once, then import the caption file and animated overlay with one click. Premiere can also import the SRT file directly.
Can it make AI videos from my script?
Yes, in the way that is free: each sentence gets a free AI picture with camera movement or a free stock clip, plus an AI voice and animated captions. Fully generated AI footage needs paid graphics servers; you can make a short clip with a free Hugging Face demo and add it to any scene.
Do I need keys for stock videos?
AI pictures and Wikimedia Commons clips need nothing. Pexels and Pixabay are free too but ask for a key, which takes a minute to get and is saved only in your browser.
Can I translate captions?
Yes. Pick "Translate to English" before transcribing and Whisper writes English captions for speech in any supported language.
