Record a region.
Narrate it with AI.
A lightweight Windows tool to record a screen area or smart-capture only the frames that change — then turn them into a video or GIF with an AI (or your own) voiceover and AI-generated captions.
What it does
Region capture
Drag to select any area with an aspect-ratio lock; move and resize with handles.
Smart image capture
Saves a frame only when pixels change — adjustable sensitivity, optional mouse tracking.
Video & GIF
Record to MP4, or build a video/GIF from images with per-image durations.
Voiceover
AI (cloud) or your-own-mic narration, time-fitted to the video length.
Multimodal AI
A vision model reads your frames to write the script and timed captions (.srt). OpenAI, Anthropic, GitHub Models & Copilot.
Themes & polish
System / light / dark themes, a custom frameless window, and a tested codebase.
