DemoPolish is an AI-powered tool that converts rough screen recordings into polished product demo videos in approximately 60 seconds. Users upload any MP4 from Loom, OBS, QuickTime, or similar tools, and DemoPolish rewrites the narration script and applies a studio-quality AI voiceover automatically. The service offers six AI voices, allowing founders to lock in a consistent brand voice across multiple clips. Pricing starts with a $1 three-day trial covering five videos, then moves to $29 per month for 100 videos.
