What is wavreel?

wavreel turns any audio narration into a ready-to-post video — automatically. Upload an MP3, WAV, or M4A file, and AI handles everything: transcription, scene generation, b-roll matching, captions, and rendering.

Time from upload to finished MP4: under 2 minutes.

How it works

1. Upload your audio — record your narration or use any TTS tool
2. AI transcribes it — word-level timestamps via Whisper
3. Scenes are generated — LLM writes a visual description for every ~3 seconds
4. Stock footage is matched — Pexels finds relevant video clips and photos automatically
5. Preview and swap — review every scene in your browser, replace anything you don't like
6. Render and download — MP4 rendered entirely in-browser using WebCodecs API

Who it's for

• Faceless YouTube creators (Reddit stories, AI news, explainers)
• Podcasters repurposing clips for TikTok and Instagram Reels
• Educational creators who want visuals to match their narration
• Anyone publishing YouTube Shorts without showing their face

Key features

• No software to install — runs entirely in the browser
• On-device transcription option — audio never leaves your device
• Ken Burns effects — subtle zoom/pan keeps static images alive
• Word-synced captions — auto-generated and burned in
• Swap any clip — full editorial control before rendering
